Detailed Description

In order to make those skilled in the art better understand the technical solutions in one or more embodiments of the present disclosure, the technical solutions in one or more embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in one or more embodiments of the present disclosure. It is to be understood that the described embodiments are only a few, and not all embodiments. All other embodiments that can be derived by one of ordinary skill in the art from one or more embodiments of the disclosure without making any creative effort shall fall within the protection scope of the present application.

When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification. Rather, they are merely examples of systems and methods consistent with certain aspects of the present description, as detailed in the appended claims.

As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information, without departing from the scope of the present specification. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.

In practical application, a screenshot mode of calling a webpage screenshot function of a browser is usually adopted to complete screenshot of a page indicated by a user. However, screenshots obtained by the method when processing a long webpage often include much information irrelevant to screenshot intentions, and when processing a webpage of a "rolling load" type (such as microblog, dynamic bar pasting, and the like), problems such as program crash and the like caused by an overlarge webpage size are also caused.

In view of this, the present specification discloses a technical solution for dynamically determining whether page loading needs to be stopped in the process of loading a page to be captured, and capturing a screenshot only on the loaded part after stopping page loading.

When the method is realized, in the loading process of the page to be subjected to screenshot, judging whether page elements related to screenshot in the page to be subjected to screenshot are completely loaded or not, and stopping the loading of the page to be subjected to screenshot in response to the completion of the loading of the page elements related to screenshot; and then, only the loaded part in the page to be screenshot can be subjected to screenshot.

In the technical scheme, on one hand, the problem of program crash when the screenshot is carried out on the ultra-long page can be avoided due to the fact that the page loading is stopped in time; on the other hand, the loading of the stop page is performed on the premise that the image obtained by the final screenshot contains all the content related to the screenshot after the page elements related to the screenshot are loaded, so that the irrelevant content in the obtained image is reduced, the user experience is improved, and the waste of computer resources is reduced.

The present application is described below with reference to specific embodiments and specific application scenarios.

Referring to fig. 1, fig. 1 is a page screenshot method provided in an embodiment of the present specification, where the method includes the following steps:

s101, analyzing a screenshot request initiated by a user to obtain a uniform resource locator UR L of a page to be screenshot;

s102, loading the page to be screenshot according to the UR L;

s103, judging whether the loading of the page elements related to the screenshot is finished in the loading process;

and S104, responding to the completion of loading of the page elements related to the screenshot, stopping the loading, and performing screenshot on the loaded part in the page to be screenshot.

In the present specification, the main body for executing the above method may be selected according to specific situations and specific requirements, and the present specification is not limited; for example, the system may be a cloud server that receives a screenshot request from a user through a network connection, a personal computer of the user, a screenshot request from the user through a communication mechanism between software modules, and the like.

In an embodiment shown, the method is applied to a distributed server cluster, and the screenshot request may include sub-requests corresponding to a plurality of pages to be screenshot; the distributed server cluster can respectively complete the screenshot tasks of the multiple pages to be screenshot according to a preset distribution algorithm.

In the description, a user-initiated screenshot request can be responded, and a uniform resource locator UR L of a page to be screenshot can be obtained, and specifically, the process has multiple implementation modes, and the description is not specifically limited, for example, a UR L field of the page to be screenshot can be directly carried in the screenshot request, the corresponding UR L can be obtained by analyzing the screenshot request, keywords corresponding to the page to be screenshot can also be carried in the screenshot request, and the corresponding UR L can also be indirectly obtained through the keywords.

In an embodiment shown, the screenshot request may carry a character string for indicating a page to be screenshot, and after the character string is obtained from the request, the character string may be further analyzed to obtain UR L of the page to be screenshot, where the analyzing method may be semantic analysis based on natural language, or analysis based on specific codes such as short website, sharing code, and the like, and those skilled in the art may select the method according to specific situations, and the description is not specifically limited;

for example, the screenshot request may carry a character string of an official microblog page indicating "pay for treasure", and after the request is analyzed and the character string is acquired, semantic information of the character string may be further extracted through a semantic analysis algorithm, and a mapping relation table between preset semantic information and UR L is queried according to the semantic information of "pay for treasure" and "microblog", so that UR L of the official microblog page of "pay for treasure" may be acquired as UR L of the page to be screenshot.

In this specification, after the UR L of the page to be screenshot is obtained, the page to be screenshot may be loaded according to the UR L.

In this specification, in the loading process of the page to be screenshot, whether the screenshot related element is completely loaded or not may be determined, and specifically, the trigger mechanism of the determination is not specifically limited in this specification; for example, the triggering may be performed periodically according to a preset time interval, or according to the number of loaded elements in the page, or according to the capacity of the page file, or may combine the above triggering manners freely; for example, the judgment on whether the screenshot related element is completely loaded may be triggered every 100 milliseconds, or the judgment on whether the screenshot related element is completely loaded may be triggered every 20 page elements.

In this specification, the screenshot related element refers specifically to an element related to the purpose of screenshot, and may be specified by a user; specifically, the mode designated by the user can be based on the screenshot request, and can also be preset in the system; for example, a screenshot request initiated by a user may include a character string such as "photograph steal evidence collection" for specifying a screenshot related element as a photograph in a web page; for another example, the user may preset that, for all screenshots of forum pages, all screenshot-related elements may be specified as the speaking content of the forum user, and do not include related popularization information and the like.

In the description, whether the page elements related to the screenshot are loaded or not can be judged according to various different standards, and the description does not need to be specifically limited; for example, whether the page element related to the screenshot is loaded or not can be judged from the perspective of the page element related to the screenshot, and whether the page element related to the screenshot is loaded or not can be indirectly judged from the perspective of the page element unrelated to the screenshot.

Fig. 2 is a schematic diagram illustrating an embodiment of determining whether loading of a page element related to a screenshot is completed, in which in this example, it may be determined whether loading of the page element related to the screenshot is completed by determining whether a loaded element includes a tail element in the page element related to the screenshot; if the loaded elements comprise the tail elements in the page elements related to the screenshot, the page elements related to the screenshot can be determined to be completely loaded; the page elements related to screenshot can be determined by the screenshot request of the user as described above, or determined according to the preset of the user; the page structure of the page sent by the page server is received firstly in the loading process of the page to be captured; for example, the page structure is in the form of html tree structure, so that the last element in the page elements related to the screenshot can be determined by the abstract structure of the page to be screenshot;

for example, if a user specifies that the user comment content in a certain page is to be intercepted, the last element in the user comment content can be determined according to the tree structure of the html file; in the loading process, after the end element is detected to be completely loaded, the page element related to the screenshot can be considered to be completely loaded.

In an embodiment shown, the screenshot display method can be implemented by judging whether the loaded elements include preset target elements for indicating that the screenshot related elements are possibly loaded; if so, the page element related to the screenshot is considered to be completely loaded;

for example, when screenshot evidence is obtained for a certain page embezzled with a photographic picture, since it is determined that APP promotion information at the bottom of the page obviously does not belong to a related page element that needs to be obtained, in the page loading process, it is detected that APP promotion information appears as loaded content, that is, it can be considered that the page element related to screenshot (in this example, an embezzled photographic picture in the page body) has been loaded.

In one embodiment shown, the screenshot-independent elements may be page elements related to advertisements; such as picture advertisements at the bottom of the page, sharing inducing links, recommendation of related articles, etc.; those skilled in the art can automatically specify the specific types of the screenshot-independent elements according to specific requirements.

In this specification, in response to a judgment result that the page element related to the screenshot is completely loaded, the loading of the page to be screenshot may be stopped, and the screenshot may be performed on the loaded part of the page to be screenshot, and a specific screenshot manner may refer to a related technology, which is not limited in this specification.

In an embodiment shown, the final screenshot can be obtained by a sectional screenshot mode; specifically, under the condition that it is determined that the size of the loaded part in the page to be screenshot is greater than the preset size threshold, the loaded part in the page to be screenshot may be divided into a plurality of fragments, the position relationship among the plurality of fragments is recorded, and after the plurality of fragments are respectively screenshot, the screenshots of the plurality of fragments may be spliced into the screenshots of the loaded part in the page to be screenshot according to the recorded position relationship.

In this specification, before screenshot is performed on a loaded part in the page to be screenshot, the loaded part in the page to be screenshot may be preprocessed to obtain a better screenshot effect; specifically, the preprocessing mode may include deleting screenshot interference elements in a page to be screenshot; for example, floating advertisements, recommendation information, shortcut buttons, etc. that may obscure screenshot related elements are deleted.

In one embodiment, the pretreatment may also include other pretreatment methods; for example, a folding element in a page may be expanded such that the folded content is displayed in its entirety and is screenshot; for another example, the display style of the designated element may be changed to enhance the display effect of the designated element; as another example, screenshot markers can be added to elements in the page to highlight content that needs attention, and so on.

Referring to fig. 3, fig. 3 is a diagram illustrating a comparison between an original page of a page to be captured and an image obtained by capturing a picture; in the example of fig. 3, the text images 1 and 2 are page elements related to screenshot, and it can be seen that, after preprocessing, floating advertisements blocking the text images can be removed, the text image 2 originally hidden by folding can be expanded and displayed, the text image 1 needing important prompt is added with screenshot marks, and related recommendation at the tail of the page and buttons of "returning to the first page" and "adding collection" can not appear in the image obtained by final screenshot due to the stop of loading.

In this specification, the screenshot request of the user may also carry other customized information to implement more customized features of the screenshot function.

In an embodiment shown, a screenshot request of a user may carry requirement information indicating a preprocessing mode, and correspondingly, when the preprocessing process is executed, the preprocessing mode may be determined according to the requirement information carried in the screenshot request of the user, and further, the page to be screenshot is preprocessed according to the determined preprocessing mode;

for example, the screenshot request of the user may carry requirement information indicating that floating advertisements need to be removed and hidden texts need to be expanded, and when the preprocessing process is executed, the preprocessing mode that needs to be executed may be determined to include removing interfering content (floating advertisements) and expanding hidden content (texts) according to the requirement information, and preprocessing is correspondingly executed.

In an embodiment shown, a screenshot request initiated by a user may carry a specification identifier for indicating a screenshot specification; therefore, the loaded part in the screenshot page can be subjected to screenshot according to the screenshot specification indicated by the specification identification carried in the screenshot request initiated by the user;

for example, specification identifiers of screenshot specifications such as a picture format, a resolution, a color specification and the like indicating that a user needs a webpage screenshot can be carried in a screenshot request initiated by the user, and during a screenshot stage, a loaded part in a screenshot page can be subjected to screenshot according to the screenshot specification indicated by the specification identifiers.

In this specification, a better screenshot effect can be obtained by further processing an image obtained by screenshot.

In one embodiment shown, a machine learning model for determining the position of interference information in an image can be used to determine the position of the interference information in the image obtained by screenshot in the image, and further remove the interference information at the position from the image through image processing; specifically, the machine learning model may be obtained by training a page screenshot of a plurality of positions marked with the interference element as a training sample;

for example, an image obtained by screenshot for a page, which still contains a certain type of advertisement information, may interfere with the screenshot, and thus a machine learning model for determining the location of the type of advertisement information in the image may be invoked, located from the image, and removed from the image by an image processing algorithm. By the method, the interference information in the screenshot can be removed from the image angle, so that the screenshot with less interference information can be obtained.

The present specification also provides a page screenshot device, please refer to fig. 4, fig. 4 is a structural example diagram of the device; the device includes:

the UR L obtaining module 401, in response to a screenshot request initiated by a user, obtains a uniform resource locator UR L of a page to be screenshot;

the page loading module 402 loads the page to be screenshot according to the UR L, and judges whether the loading of the page elements related to the screenshot is finished in the loading process, wherein the page elements related to the screenshot are the page elements appointed by the user;

the execution module 403, in response to the completion of loading the page element related to the screenshot, stops loading the page to be screenshot, and performs screenshot on the loaded part of the page to be screenshot.

In this specification, the UR L obtaining module 401 may obtain the uniform resource locator UR L of the page to be screenshot based on a screenshot request initiated by a user, and the above process may have various implementation manners, and this specification is not particularly limited, for example, the screenshot request may directly carry the UR L field of the page to be screenshot, and the corresponding UR L may be directly extracted from the screenshot request, or the screenshot request may carry a character string corresponding to the UR L of the page to be screenshot, and then the corresponding UR L is indirectly obtained by means of querying and the like.

In an illustrated embodiment, the screenshot request may carry a character string indicating UR L of the page to be screenshot, and the UR L obtaining module 401 may further obtain UR L indicated by the character string by parsing the character string, for example, if the character string is "abc bar home page", it may determine, according to the character string, that the UR L indicated by the character string is UR L of "abc bar home page", and thus, the UR L of the page to be screenshot is UR L of "abc bar home page", where the manner of determining the corresponding UR L based on the character string may be a manner of keyword query or a manner of semantic analysis, and may specifically be flexibly selected according to actual development requirements, and this specification is not particularly limited.

In this specification, the screenshot related element refers specifically to an element related to the purpose of screenshot, and may be specified by a user; specifically, the mode designated by the user can be based on the screenshot request, and can also be preset in the system; for example, the screenshot request initiated by the user may include a character string such as "photograph steal evidence collection", and the screenshot related elements are the photographed pictures in the web page; for another example, the user may preset, and for the screenshot of the forum page, the screenshot-related element may be the speaking content of the forum user, but does not include the related promotion information, and the like.

In this specification, the page loading module 402 determines whether the page element related to the screenshot is completely loaded, which may be according to various different standards, and this specification does not need to be specifically limited; for example, whether the page element related to the screenshot is loaded or not can be judged from the perspective of the page element related to the screenshot, and whether the page element related to the screenshot is loaded or not can be indirectly judged from the perspective of the page element unrelated to the screenshot.

In an illustrated embodiment, the page loading module 402 may determine whether the page element related to the screenshot is completely loaded by determining whether the loaded element includes an end element in the page element related to the screenshot; if the loaded elements comprise the tail elements in the page elements related to the screenshot, the page elements related to the screenshot can be determined to be completely loaded; the page elements related to screenshot can be determined by the screenshot request of the user as described above, or determined according to the preset screenshot page element type; and because the page to be screenshot first receives the abstract structure of the page in the form of the html tree structure in the loading process, the tail element in the page elements related to the screenshot can be determined by the abstract structure of the page to be screenshot.

In one embodiment shown, page loading module 402 may determine whether the page elements related to the screenshot are loaded completely by determining whether loaded page elements include screenshot-independent elements indicating that the page elements related to the screenshot are loaded completely; if the judgment result is yes, the page elements related to the screenshot are considered to be loaded completely; for example, the screenshot-unrelated element is a page-based advertisement, generally speaking, the occurrence of the page-based advertisement means that all page elements related to the screenshot in the page are completely loaded, and if the page-based advertisement is already loaded, a judgment can be made, that is, all page elements related to the screenshot in the page are completely loaded.

In one embodiment, the screenshot-independent elements may be page elements related to advertisements; such as photo ads at the bottom of the page, share inducement links, related article recommendations, and so forth.

In this specification, the execution module 403, in response to a judgment result that the page element related to the screenshot is completely loaded, may stop loading the page to be screenshot, and perform the screenshot on the loaded part of the page to be screenshot, where a specific screenshot manner may refer to a related technology, and this specification is not limited specifically.

In an embodiment shown, the execution module 403 may obtain a final screenshot in a sectional screenshot manner; specifically, under the condition that it is determined that the size of the loaded part in the page to be screenshot is greater than the preset size threshold, the loaded part in the page to be screenshot may be divided into a plurality of fragments, the position relationship among the plurality of fragments is recorded, and after the plurality of fragments are respectively screenshot, the screenshots of the plurality of fragments may be spliced into the screenshots of the loaded part in the page to be screenshot according to the recorded position relationship.

In this specification, the apparatus may further include a preprocessing module, which preprocesses the loaded part of the page to be screenshot, so as to obtain a better screenshot effect; specifically, the preprocessing mode may include deleting screenshot interference elements in a page to be screenshot; for example, floating advertisements, recommendation information, shortcut buttons, etc. that may obscure screenshot related elements are deleted.

In one embodiment, the pretreatment may also include other pretreatment methods; for example, hidden elements in a page may be expanded such that hidden content (e.g., folded multi-layer reference comments) is fully displayed and screenshot; for another example, the display style of the specified page element can be changed, and the display effect of the specified element can be enhanced; as another example, screenshot markers can be added to elements in the page to highlight content that needs attention, and so on.

In an embodiment shown, a screenshot request of a user may carry requirement information indicating a preprocessing mode, and correspondingly, the preprocessing module may determine the preprocessing mode according to the requirement information carried in the screenshot request of the user, and further preprocess the page to be screenshot according to the determined preprocessing mode.

In an embodiment shown, a screenshot request initiated by a user may carry a specification identifier for indicating a screenshot specification; therefore, the execution module 403 may perform screenshot on the loaded part in the screenshot page according to the screenshot specification indicated by the specification identifier carried in the screenshot request initiated by the user.

In this specification, the apparatus may further include an image processing module, and may further process an image obtained by capturing the image, so as to obtain a better image capturing effect.

In an illustrated embodiment, the image processing module may train a machine learning model obtained by using a screenshot of a page marked with a position of a plurality of interference elements as a training sample to further process the screenshot image; specifically, the image may be input into the trained machine learning model to determine the position of the interference element in the image, and the image may be further processed based on the position to delete the interference element.

The implementation process of the functions and actions of each module in the above device is specifically described in the implementation process of the corresponding step in the above method, and is not described herein again.

In practical application, a screenshot mode of calling a webpage screenshot function of a browser is usually adopted to complete screenshot of a page indicated by a user. However, screenshots obtained by the method when processing complex webpages often include many elements which can interfere with information related to screenshots, so that key information needing to be proved is accidentally shielded.

In view of this, the present specification discloses a technical solution for preprocessing a page to be screenshot before the page is subjected to screenshot.

When the method is realized, after the loading of the page to be subjected to screenshot is finished, preprocessing operation including deleting interference elements is carried out on the page to be subjected to screenshot; and then, screenshot can be carried out on the preprocessed page to be subjected to screenshot.

In the technical scheme, because the interference elements in the original page are removed by means of preprocessing, the condition that the interference elements exist in the screenshot result or the screenshot related elements are accidentally shielded is avoided, and the completeness of the screenshot related elements in the page is ensured.

Referring to fig. 6, fig. 6 is a page screenshot method provided in an embodiment of the present specification, where the method performs the following steps:

s601, responding to a screenshot request initiated by a user, and acquiring a uniform resource locator UR L of a page to be screenshot;

s602, loading the page to be screenshot according to the UR L;

s603, after the page to be captured is loaded, preprocessing the page to be captured; the preprocessing comprises deleting screenshot interference elements in the page to be screenshot;

and S604, performing screenshot on the preprocessed page to be screenshot.

In the description, after the UR L of the page to be screenshot is obtained, the page to be screenshot can be loaded according to the UR L.

In the description, the page to be subjected to screenshot can be preprocessed to obtain a better screenshot effect; specifically, the preprocessing mode may include deleting screenshot interference elements in a page to be screenshot; for example, floating advertisements, recommendation information, shortcut buttons, etc. that may obscure screenshot related elements are deleted.

In one embodiment, the pretreatment may also include other pretreatment methods; for example, hidden elements in a page may be expanded such that hidden and folded content is displayed and screenshot in its entirety; for another example, the display style of the designated element may be changed to enhance the display effect of the designated element; as another example, screenshot markers can be added to elements in the page to highlight content that needs attention, and so on.

for example, the screenshot request of the user may carry requirement information indicating that floating advertisements need to be removed and a folded text needs to be expanded, and when the preprocessing process is executed, the preprocessing mode that needs to be executed may be determined to include removing interfering content (floating advertisements) and expanding the folded content (text) according to the requirement information, and preprocessing is correspondingly executed.

Referring to fig. 7, fig. 7 is a diagram illustrating a comparison example before and after preprocessing a certain page to be captured; in the example of fig. 7, the text images 1 and 2 are page elements related to screenshot, and it can be seen that, after preprocessing, floating advertisements blocking the text images can be removed, the original folded text image 2 can be expanded and displayed, the text image 1 needing important prompt is added with screenshot marks, and related recommendation and "return to the first page" and "add collection" buttons at the tail of the page can also be regarded as interfering elements to be removed, and will not appear in the image obtained by final screenshot.

In this specification, in the process of loading the page to be screenshot, it may be further determined whether loading of the screenshot-related element is completed, and in response to completion of loading of the page element related to the screenshot, the loading of the page to be screenshot may be stopped; specifically, the trigger mechanism of the determination is not specifically limited in this specification; for example, the triggering may be performed periodically according to a preset time interval, or according to the number of loaded elements in the page, or according to the capacity of the page file, or may be freely combined. And the loading of the page is stopped in time, so that the loading of elements irrelevant to screenshot can be reduced on the premise of ensuring that the page elements relevant to screenshot are not lost, and the occupation ratio of the elements relevant to screenshot in the final screenshot is improved.

In this specification, a screenshot related element refers specifically to an element related to a screenshot purpose, which may be specified by a user; specifically, the mode designated by the user can be based on the screenshot request, and can also be preset in the system; for example, a screenshot request initiated by a user may include a character string such as "photograph steal evidence collection" for specifying a screenshot related element as a photograph in a web page; for another example, the user may preset that, for all screenshots of forum pages, all screenshot-related elements may be specified as the speaking content of the forum user, and do not include related popularization information and the like.

Fig. 8 is a schematic diagram illustrating an embodiment of determining whether the page element related to the screenshot is completely loaded, in this example, it may be determined whether the page element related to the screenshot is completely loaded by determining whether the loaded element includes a tail element in the page element related to the screenshot; if the loaded elements comprise the tail elements in the page elements related to the screenshot, the page elements related to the screenshot can be determined to be completely loaded; the page elements related to screenshot can be determined by the screenshot request of the user as described above, or determined according to the preset of the user; the page structure of the page sent by the page server is received firstly in the loading process of the page to be captured; for example, the page structure is in the form of html tree structure, so that the last element in the page elements related to the screenshot can be determined by the abstract structure of the page to be screenshot;

In an embodiment shown, the final screenshot can be obtained by a sectional screenshot mode; specifically, under the condition that the size of the preprocessed page to be subjected to screenshot is determined to be larger than a preset size threshold, the page to be subjected to screenshot can be divided into a plurality of fragments, the position relation among the plurality of fragments is recorded, and after the plurality of fragments are respectively subjected to screenshot, screenshots of the plurality of fragments can be spliced into screenshots of the page to be subjected to screenshot according to the recorded position relation.

In an embodiment shown, a screenshot request initiated by a user may carry a specification identifier for indicating a screenshot specification; therefore, the screenshot can be performed on the page to be screenshot according to the screenshot specification indicated by the specification identification carried in the screenshot request initiated by the user;

for example, specification identifiers of screenshot specifications such as a picture format, a resolution, a color specification and the like indicating that a user needs a webpage screenshot can be carried in a screenshot request initiated by the user, and during a screenshot stage, a screenshot can be performed on a screenshot page according to the screenshot specification indicated by the specification identifiers.

The present specification also provides a page screenshot device, please refer to fig. 9, fig. 9 is a structural example diagram of the device; the device includes:

a UR L obtaining module 901, which responds to a screenshot request initiated by a user, and obtains a uniform resource locator UR L of a page to be screenshot;

the page loading module 902 loads the page to be captured according to the UR L;

the page preprocessing module 903 is used for preprocessing the page to be captured after the page to be captured is loaded; the preprocessing comprises deleting screenshot interference elements in the page to be screenshot;

and a screenshot executing module 904, which is used for performing screenshot on the preprocessed page to be screenshot.

In this specification, the UR L obtaining module 901 may obtain the uniform resource locator UR L of the page to be screenshot in response to a screenshot request initiated by a user, specifically, the process has various implementation manners, and this specification is not particularly limited, for example, the UR L field of the page to be screenshot may be directly carried in the screenshot request, the corresponding UR L may be obtained by analyzing the screenshot request, the keyword corresponding to the page to be screenshot may also be carried in the screenshot request, and the corresponding UR L may also be indirectly obtained by the keyword.

In this specification, a page preprocessing module 903 in the device preprocesses the page to be captured to obtain a better capture effect; specifically, the preprocessing mode may include deleting screenshot interference elements in a page to be screenshot; for example, floating advertisements, recommendation information, shortcut buttons, etc. that may obscure screenshot related elements are deleted.

In this specification, the apparatus may further include a dynamic loading module, which determines whether the loading of the page element related to the screenshot is completed in the loading process; and stopping loading the page to be screenshot in response to the completion of loading the page elements related to the screenshot.

In the specification, the dynamic loading module judges whether the loading of the page elements related to the screenshot is finished or not according to various different standards, and the specification does not need to be specifically limited; for example, whether the page element related to the screenshot is loaded or not can be judged from the perspective of the page element related to the screenshot, and whether the page element related to the screenshot is loaded or not can be indirectly judged from the perspective of the page element unrelated to the screenshot.

In an embodiment shown in the foregoing, the dynamic loading module may further determine whether the page element related to the screenshot is completely loaded by judging whether the loaded element includes a tail element in the page element related to the screenshot; if the loaded elements comprise the tail elements in the page elements related to the screenshot, the page elements related to the screenshot can be determined to be completely loaded; the page elements related to screenshot can be determined by the screenshot request of the user as described above, or determined according to the preset screenshot page element type; and because the page to be screenshot first receives the abstract structure of the page in the form of the html tree structure in the loading process, the tail element in the page elements related to the screenshot can be determined by the abstract structure of the page to be screenshot.

In an embodiment shown, the dynamic loading module may further determine whether the page elements related to the screenshot are completely loaded by determining whether the loaded page elements include a screenshot-independent element indicating that the page elements related to the screenshot are completely loaded; if the judgment result is yes, the page elements related to the screenshot are considered to be loaded completely; for example, the screenshot-unrelated element is a page-based advertisement, generally speaking, the occurrence of the page-based advertisement means that all page elements related to the screenshot in the page are completely loaded, and if the page-based advertisement is already loaded, a judgment can be made, that is, all page elements related to the screenshot in the page are completely loaded.

In this specification, the screenshot executing module 904 may perform screenshot on the preprocessed page to be subjected to screenshot, and a specific screenshot manner may refer to a related technology, which is not limited in this specification.

In an embodiment shown, the screenshot executing module 904 may obtain a final screenshot in a sectional screenshot manner; specifically, under the condition that the size of the preprocessed page to be subjected to screenshot is larger than a preset size threshold, the page to be preprocessed to be subjected to screenshot can be divided into a plurality of fragments, the position relation among the plurality of fragments is recorded, after the plurality of fragments are respectively subjected to screenshot, the screenshots of the plurality of fragments can be spliced into the screenshot of the preprocessed page to be subjected to screenshot according to the recorded position relation.

In an embodiment shown, a screenshot request initiated by a user may carry a specification identifier for indicating a screenshot specification; therefore, the screenshot executing module 904 can perform screenshot on the preprocessed page to be screenshot according to the screenshot specification indicated by the specification identifier carried in the screenshot request initiated by the user.
