Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic structural diagram of an implementation environment according to embodiments of the present invention. As shown in fig. 1, the implementation environment includes: terminal device 110, web server 120, and database 130.
The terminal device 110 operates with means for paging display data, such as a browser. The terminal device 110 may be a mobile phone, a tablet computer, a laptop portable computer, a desktop computer, and the like. The browser may include, among other things, means for displaying and managing paginated display data of pages, such as an Internet browser (IE), Internet Explorer, a roaming browser, and the like.
The terminal device 110 may be connected to the web server 120 through a wireless network or a wired network.
The website server 120 may be a server, a server cluster composed of several servers, or a cloud computing service center.
The database 130 may be a device for storing data, and may be connected to the web server 120 through a wired or wireless manner, so that the web server 120 reads data from the database 130.
Fig. 2 is a flowchart illustrating a method for displaying data in a page-wise manner according to an embodiment of the present invention. The method is applied to the browser in the terminal equipment. As shown in FIG. 2, when the browser exposes data from a Uniform Resource Locator (URL), the method includes the following steps.
In an embodiment of the present invention, after a user inputs a search keyword, the browser determines whether a page is the first page when the browser responds to the user's search request and determines to initially load the page. Alternatively, when an operation control for linking to the next page on the page, such as a "next page" button, is clicked, the browser determines whether the next page is the first page when determining that the next page is ready to be presented in response to the click request.
In one embodiment of the invention, a page number value may be set in preparation for presenting data from a URL and initialized to a first value. The first value is typically zero and may be a specific integer. In the subsequent page display process, when a certain page is displayed, the existing page numerical value is increased by one. For example, when the initial first value is zero, and is shown to the first page, then the first value is incremented by one, i.e., the current page value is one. In an embodiment of the present invention, whether the page is the first page is determined by determining whether the current page value is the first value. When the page value is the first value, judging that the page is a first page; otherwise, the page is judged not to be the first page. In an embodiment of the present invention, it may also be determined whether the page is the first page by determining whether the page number value is the first numerical value and whether the data size of the currently cached data is zero. If the current page value is the initialized first value and the data volume of the current cached data is zero, the page is determined to be the first page. If the current page value is not the first value or the data amount of the current cached data is not zero, the page is determined not to be the first page.
Alternatively, when data from a URL is to be presented, the value of the page flag is set and initialized to invalid, e.g., 0 or 1. When the page is displayed, judging whether the value of the page zone bit is invalid, if the value of the page zone bit is invalid, modifying the value of the page zone bit to be valid, for example, if 0 represents invalid, modifying the value of the page zone bit to be 1; if 1 represents invalid, the value of the flag bit of the page is modified to 0. Whether the page is the first page can be judged by judging whether the value of the page flag bit is invalid. And when the value of the page flag bit is invalid, determining that the page is the first page. Or, judging whether the value of the flag bit of the page is invalid or not, and judging whether the data volume of the current cached data is zero or not. And if the value of the page flag bit is invalid and the data volume of the current cached data is zero, judging that the page is the first page. And if the value of the flag bit of the page is valid or the data amount of the currently cached data is not zero, judging that the page is not the first page.
When the page is a first page, the browser acquires first data from the website server according to a first data unit and displays the first data on the page. Specifically, the browser sends a data acquisition request to the website server, where the data acquisition request carries a first data unit. And the website server acquires a certain amount of data from the database according to the first data unit and sends the data to the browser. In an embodiment of the invention, the first data unit is a data amount of which one page can display data. According to the first data unit, the browser can acquire data of one page at most from the website server, namely data which can be displayed by one page. The browser may retrieve less than one page of data, e.g., half a page of data, or may not retrieve data. If the data about the URL currently existing in the website server is greater than or equal to the first data unit, acquiring the data of the first data unit, namely the data capable of being displayed by one page, from the website server. If the amount of data currently existing in the Web server about the URL is less than the first data unit, then data currently existing about the URL, e.g., half-page data, is obtained from the Web server. In an embodiment of the present invention, when the browser obtains a page of data from the web server, the page of data is displayed according to a default page display setting. When the acquired data is less than one page, for example, half page data, the browser may display the half page data according to a default page setting, that is, the data is displayed in a half page, and the half page is blank. Or the browser may present the half page of data on the entire page, except that the spacing between data is approximately twice the default.
In an embodiment of the present invention, the browser further obtains and caches the second data from the website server according to a second data unit. The second data unit is a data amount of which at least one page can display data. For example, the second data unit is a data amount of which two or more pages can show data, or a data amount of which one page can show data, or less than a data amount of which one page can show data, for example, half page data or zero. The second data unit may be determined according to the capacity of the above-described buffering means and the time and resources required to perform one buffering. In the specific process of acquiring the second data, if the amount of data currently existing in the web server about the URL is greater than or equal to the second data unit, the data of the second data unit is acquired from the web server. If the amount of data currently existing in the Web server about the URL is less than the second unit of data, then the currently existing data about the URL is obtained from the Web server.
In an embodiment of the present invention, in the process of displaying data in a paging manner, the browser needs to send a data obtaining request to the web server to request a certain amount of data. And the website server reads a certain amount of data from a database according to the data acquisition request and sends the data to the browser. The browser caches the data in its own cache device, or in a separate cache device. Because the data to be displayed is cached in the cache device, the data is only required to be read from the cache device when the data is displayed subsequently, and the data is not required to be read from a database through a website server when the data is displayed every time, so that the time for reading the data can be shortened, and the efficiency of displaying the data in pages is improved.
In an embodiment of the present invention, it is determined whether the data size of the second data is zero. And if the data volume of the second data cached currently is zero, judging that the page is the last page. If the data size of the second data is zero, it indicates that the browser does not obtain data from the web server, i.e., the database has no more data about the URL. When the data amount of the second data is not zero, it is determined that the page is not the last page.
In an embodiment of the invention, other execution sequences may be utilized to retrieve and present the first data from the web server and to retrieve and cache the second data. For example, the first data and the second data may be first obtained from the website server according to the first data unit and the second data unit, and then the first data is displayed and the second data is cached, or the second data is cached and then the first data is displayed. Or, the second data is firstly obtained from the website server and cached, and then the first data is obtained from the website server and displayed.
In one embodiment of the present invention, data may be obtained from the web server in an asynchronous request manner. Since the web server acquires data from the database after the browser issues a data acquisition request, and the operations of presenting data and caching data are performed by the browser, the above-described operation of acquiring data and the operation of presenting and caching data can be performed in parallel. For example, after a browser acquires first data from a website server, before or after the first data is presented, the browser sends a data acquisition request to the website server, and waits for receiving second data from the website server during presentation of the first data. Because the above operations can be executed in parallel, the time required by the paging display can be shortened, and the paging display efficiency can be improved.
In an embodiment of the present invention, when the page is not the first page, the browser may determine whether the page is the last page according to the data amount of the currently cached data; or the browser can acquire third data from the website server according to the second data unit and judge whether the page is the last page according to the data volume of the third data; or the browser may determine whether the page is the last page according to the data amount of the currently cached data and the data amount of the third data. In an embodiment of the present invention, after determining whether the page is the last page, fourth data may be obtained from the currently cached data according to the first data unit and displayed in the page. Or before determining whether the page is the last page or in the process of determining whether the page is the last page, acquiring fourth data from the currently cached data according to the first data unit and displaying the fourth data in the page.
In an embodiment of the invention, the data amount of the currently buffered data may be smaller than the first data unit, and may also be equal to or larger than the first data unit. And if the data amount of the currently cached data is larger than or equal to the first data unit, the data amount of the fourth data acquired from the currently cached data is equal to the first data unit. And if the data volume of the currently cached data is smaller than the first data unit, the data volume of the fourth data acquired from the currently cached data is the data volume of the currently cached data.
FIG. 2A is a flowchart illustrating a method for determining whether a page is a last page in the embodiment shown in FIG. 2. As shown in fig. 2A, the second data unit requested from the web server is a data amount that can show data for one page each time data is cached. The method comprises the following steps.
FIG. 2B is a flowchart illustrating a method for determining whether a page is a last page in the embodiment shown in FIG. 2. As shown in fig. 2B, the second data unit requested from the web server is a data amount that can show data for one page each time data is cached. The method comprises the following steps.
In step 203B, when the data amount of the third data is zero, it is determined that the page is the last page.
In step 204B, when the data amount of the third data is not zero, it is determined that the page is not the last page.
FIG. 2C is a flowchart illustrating a method for determining whether a page is a last page in the embodiment shown in FIG. 2. As shown in fig. 2C, the method includes the following steps.
And step 204C, when the data volume of the currently cached data is zero, judging that the page is the last page.
In step 205C, when the data amount of the currently cached data is not zero, it is determined that the page is not the last page.
In the embodiment of the present invention, the second data unit may be a data amount larger than one page of data that can be displayed, or may be equal to or smaller than one page of data that can be displayed.
FIG. 3 is a flowchart illustrating a method for displaying data in a page-wise manner according to an embodiment of the present invention. The method is applied to the browser in the terminal equipment. In the embodiment of the invention, the data unit requested from the website server at each caching is the data volume of one page capable of displaying data, which is referred to as one page of data for short. When data is displayed each time, the data unit requested to the website server or the currently cached data is the data volume of the data which can be displayed in one page, which is referred to as one page of data for short. As shown in fig. 3, when the browser exposes data from a URL, the method includes the following steps.
When a page is initialized, a page show event is detected. Alternatively, when the user operates the operation space for linking to the next page, it is detected that the page presentation event is triggered.
In one embodiment of the invention, a page number value may be set and initialized to zero when preparing to present data from a URL. In the subsequent page display, each page of data is displayed, the page number value is increased by one.
In this embodiment, whether the page is the first page is determined by determining whether the page count value is zero. When the page value is zero, step 303 is performed. When the page count value is not zero, step 304 is performed. Or, in the embodiment of the present invention, the value of the page flag is set and initialized to be invalid, when the page is displayed, it is determined whether the value of the page flag is invalid, and if the value of the page flag is invalid, the value of the page flag is modified to be valid. And judging whether the page is the first page or not by judging whether the value of the page flag bit is invalid or not, and judging that the page is the first page when the value of the page flag bit is invalid.
Step 303, requesting the website server to acquire two pages of data, displaying one page of data, caching the rest of data, and executing step 306.
In an embodiment of the present invention, a page of data may be obtained from the website server and displayed, and then a page of data may be obtained from the website server and cached. When the page is displayed, the page number value is added by one, namely the current page number value is one.
And step 304, requesting to acquire a page of data from the currently cached data and displaying the page of data.
In this step, the page count value is incremented by one to obtain a new page count value.
In an embodiment of the present invention, after the operation of presenting the data in step 304 and the operation of the web server receiving the data obtaining request, the operation of obtaining the data from the database and sending the data to the browser may be executed in parallel.
In this embodiment, when the currently cached data is zero, it indicates that the data obtained from the website server in step 303 or step 305 is zero, that is, the data is not obtained.
In the embodiment of the present invention, the process may be directly ended when the page is determined to be the last page.
In step 308, it is determined that the page is not the last page, and a "next" button is displayed on the page. And when it is detected that the user clicks the "next page" button, step 301 is executed in response to the operation applied to the button by the user.
In the embodiment of the present invention, a description is given taking an example in which a page of data is requested to be cached every time caching is performed. In practical applications, it may also be requested to cache more than one page of data capable of showing data, for example, two pages, or it may also be requested to cache less than one page of data capable of showing data, for example, half page or one third page. In the embodiment of the present invention, when a page of data is requested to be obtained from the web server or the currently cached data, if the amount of data of the URL existing in the web server or the currently cached data is greater than or equal to the amount of the page of data, a page of data is obtained from the web server or the currently cached data; otherwise, the existing data of the URL is obtained from the website server or the currently cached data, and the data of the URL may be less than one page or may be zero.
FIG. 4 is a flowchart illustrating a method for displaying data in a page-wise manner according to an embodiment of the present invention. The method is applied to the browser in the terminal equipment. As shown in fig. 4, when the browser presents data from a URL, the method includes the following steps. In the embodiment of the invention, the data volume of the data which can be displayed on one page is requested from the website server by default when the data is cached every time, which is referred to as one page of data for short. And when the data is displayed, the data size of the data capable of being displayed on one page is requested to be acquired from the website server or the currently cached data.
At step 401, a page count value is established and initialized to zero.
At step 402, a page show event is detected to be triggered.
In embodiments of the present invention, when a page is initially loaded, it is detected that a page expose event is triggered. Alternatively, the page presentation event is detected to be triggered when the user clicks a "next page" button, triggering the page presentation event in response to the user's operation of the button.
In step 403, it is determined whether the page is the first page. When the page is the first page, go to step 404; otherwise, step 406 is performed.
In this embodiment, each time of caching, the data amount of the data requested from the web server is the data amount of the data that can be displayed on one page, so the data amount of the cached data is not greater than the data amount of the data that can be displayed on the one page, and therefore when the data amount of the currently cached data is greater than the preset data amount of the data that can be displayed on the one page, it is determined that an error occurs.
And step 408, acquiring and displaying the current cached data.
In step 409, the page is determined to be the last page.
When the page is the last page, then the "next page" button is not presented.
At step 410, a page of data is requested from the web server and cached.
In step 411, it is determined whether the data amount of the data acquired from the web server is zero. When the data amount of the data acquired from the website server is zero, executing step 409; otherwise, step 412 is performed.
In step 412, a page of data is requested from the currently cached data and displayed.
In step 413, it is determined that the page is not the last page, and the "next" button is presented on the page. When it is detected that a page show event is triggered, step 402 is performed.
In the embodiment of the present invention, when a page of data is requested to be obtained from the web server or the currently cached data, if the amount of data of the URL existing in the web server or the currently cached data is greater than or equal to the amount of the page of data, a page of data is obtained from the web server or the currently cached data; otherwise, the existing data of the URL is obtained from the website server or the currently cached data, and the data of the URL may be less than one page or may be zero.
FIG. 5 is a flowchart illustrating a method for displaying data in a page-wise manner according to an embodiment of the present invention. The method is applied to the browser in the terminal equipment. As shown in fig. 5, when the browser exposes data from a URL, the method includes the following steps. In the embodiment of the invention, the data volume of the data which can be displayed on one page is requested to the website server by default when caching is performed each time, and the data volume of the data which can be displayed on one page is requested to be acquired when the data is displayed.
In step 503, it is determined whether the page is the first page. If the page is the first page, go to step 504; otherwise, step 506 is performed.
Step 504 requests a page of data from the web server and presents it, and requests a page of data from the web server and caches it.
At step 506, a page of data is requested from the web server and cached.
And step 508, acquiring and displaying the current cached data.
In step 509, it is determined that the page is the last page.
In the embodiment of the present invention, when a page of data is requested to be obtained from the web server or the currently cached data, if the amount of data of the URL existing in the web server or the currently cached data is greater than or equal to the amount of the page of data, a page of data is obtained from the web server or the currently cached data; otherwise, the existing data of the URL is obtained from the website server or the currently cached data, and the data of the URL may be less than one page or may be zero.
