Time fragments of everyday life are more easily read using an electronic reading terminal.

For the Hypertext Markup Language (hereinafter referred to as html) page of the electronic reading terminal, the traditional paging typesetting method first determines the character environment of the article, for example, the article is a Chinese environment, and secondly, the characters in the article are all regarded as Chinese. Characters, and according to the correspondence between Chinese character size and pixel, calculate the size of space each character should occupy, so as to get the number of characters that can be accommodated in each line, and the number of lines and the number of displayed pages that can accommodate each page.

However, in html pages, whether it is a single-byte character language or a double-byte character language, there are phenomena in which characters are not unequal. For example, the width of a half-width punctuation mark or English letter in a Chinese environment is half the width of a Chinese character; in an English environment, letters and letters themselves are not equal in width. Taking the Chinese environment as an example, if the electronic reading terminal can display 100 Chinese characters, when a paragraph of text contains 100 Chinese characters, according to the traditional paging typesetting method, the display effect of the electronic reading terminal is shown in Figure 1-1. The height of the character is equal to the height of the page, and the character fills the entire page; however, if the text includes fifty Chinese characters and fifty letters, the layout of the electronic reading terminal is as shown in the traditional page layout method. As shown in 1-2, after all the characters are inserted into the page, a blank line appears at the end of the page. Obviously, using the traditional html paging layout method, it is easy to cause blank lines at the end of some pages, resulting in low page utilization, poor display performance, and affecting the user experience.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Embodiment 1

Referring to FIG. 2, a flow chart of a first implementation method of a page layout method according to an embodiment of the present invention is shown. The page layout method includes the following steps:

Step S101: Determine the number of words that the terminal display area can accommodate.

In this embodiment, when the article characters are different, the manner of determining the number of words that can be accommodated is different. Therefore, when an article is acquired, first, the character type of the article is determined, and the character type of the article is usually capable of being known from the article. Get it directly. After getting the character type of the article, the width of the character is calculated according to the determined character type. Specifically, when the character type of the article is Chinese, the width of each character may be determined according to the correspondence between the font size and the pixel of the character, or determined according to the empirical value, and the present invention does not limit this; when the article is an English character Calculate the average width of English characters. After determining the font and font size, the average width can be determined by calculating the average width value of 26 letters, or calculating the average value of the letter I with the smallest width and the letter W with the largest width. The average width of the letters. After determining the width of each character, the number of words that can be accommodated in each row is determined according to the width of the display area of the terminal, and then the number of lines that can be accommodated is determined according to the height of the display area of the terminal, thereby obtaining the number of words that the terminal display area can accommodate.

Of course, in the technical solution of the present invention, the manner in which the number of words that can be received by the display area of the terminal is determined is not limited to the foregoing description, and may be other determined manners, which are not described herein again.

In the present embodiment, first, the character width is determined, and then the number of words that can be accommodated is calculated according to the character width, and can be applied to any language without using any language, and the application range is wide.

Step S102: The article is divided into a plurality of content blocks according to the number of words that the terminal display area can accommodate.

Based on the above steps, the number of words that the terminal display area can accommodate, that is, the number of words per page, divides the content of the article into a plurality of content blocks according to the number of words per page and the total number of words of the article, and each content block is displayed for each page. Content. For example, a 1000-word article, each page can hold 100 words, and each 100 words is a content block, and the article can be divided into 10 content blocks.

Step S103: Loading the content block into the corresponding content container.

In this step, a content block is correspondingly loaded in a content container, and a content tag is added to the content block in order to facilitate management of the content block. The content tag includes a start tag and a closing tag. The start tag is usually located before the first character of the content block to indicate the start of the content block; the end tag is located after the last character of the content block to indicate the end of the content block. . The start tag and the end tag of each content block wrap the content block to form a content container corresponding to the content block. In addition, the content tag may be any known or upcoming identifier capable of identifying the content of the document, which is not limited by the present invention. In a preferred embodiment of the present invention, the content tag may be a DOM (Document Object Model) node, and each 100 characters are marked by a DOM node starting from the first character. The 100-character content container is formed for the starting DOM node and the ending DOM node of every 100 characters.

In the embodiment of the present invention, the content block is containerized to form a unified management of characters, which facilitates processing of the content, and the processing steps can be saved with respect to the character processing, and the algorithm is simple.

Step S104: Determine the current page container and its corresponding content container.

In order to be able to visually observe the display of each page, it is convenient to typeset the content block. After determining the number of pages of the article, create the same number of page containers as the article page, and the visible area of the page container simulates the display area of the terminal. . Wherein, one page container corresponds to one content container, the first page container corresponds to the first content container, the second page container corresponds to the second content container, and so on. In this step, the current page container may be the first page container, and then the content container corresponding to the current page container is the first content container.

Step S105: Insert the corresponding content container into the page container.

Among them, the characters in the content container can realize natural typesetting such as line feed and stretch alignment. After the content container is inserted into the page container, the page container can simulate the terminal display area and display the content block in the content container. When the 'current page container' is the first page container, after inserting the first content container into the current page container, in the current page container, the content block in the first content container can be visually seen in the terminal. Shows the impression in the area. In addition, the natural typesetting of the content blocks in the content container can be performed by CSS (Cascading Style Sheets) style control characters, and the natural typesetting of the characters is a technical means well known to those skilled in the art, and the present invention is here. No longer.

It should be noted that, after inserting the corresponding content container into the page container, the method may further include: determining whether there is a blank line at the end of the current page container, and when the current page container has a blank line at the end of the page, filling the current page container by performing step S106 A blank line at the end of the page; when there is no blank line at the end of the 'current page container', step S107 is performed on the current page container. The specific method for determining whether there is a blank line at the end of the current page container may be: determining the corresponding content container and Whether the height of the current page container is equal. When the corresponding content container is equal to the height of the current page container, there is no blank line at the end of the current page container; when the height of the corresponding content container and the current page container are not equal, the current page container is There is a blank line at the end of the page. Certainly, the method for judging whether there is a blank line at the end of the current page container may be other methods, and the present invention is not limited herein.

Step S106: Insert the next content container immediately adjacent to the corresponding content container into the current page container.

Among them, since the content block is inserted into the page container, a blank line appears at the end of the page container. In order to fill the blank line of the page container, at the same time, to ensure the consistency of the content displayed in the page container, insert the content container corresponding to the current page container into the current page container, and then insert the next content container immediately adjacent to the content container. After the corresponding content container of the current page container. Need to point out, in order to ensure that the content in the page container is displayed Coherence, before inserting the next content container, first determining the end tag of the current content container, according to which the next content container of the content container is inserted; preferably, the next line of the end tag may be adjacent The starting position is inserted as the starting position of the next content container, and the starting label of the next content container is inserted into the position. Due to the container nature of the content container, when the next content container is inserted into the current page container, the first line in the next content container is displayed in the first line of the hollow line of the current page container.

In addition, since there is only a blank line in the current page container, only the next content container is inserted, only part of the content is displayed, and the other part is located in the invisible area of the current page container, and therefore cannot be displayed.

In addition, in order to ensure that the content container corresponding to the current page container is an entire line when displayed on the last line, when the content block is determined, the characters of the last line can be divided into the next content container. The present invention will not be described in detail for the specific division method.

Step S107: Typesetting the current page container.

Wherein, when the 'current page container' is the first content container, the layout of the current page container has been completed. Since the content displayed by the current page container is partially overlapped with the content displayed by the next next page container, the offset of the repeated portion needs to be calculated so as to typeset the next page container according to the offset.

It can be seen from the above embodiment that the page layout method provided by the embodiment of the present invention divides a plurality of content blocks obtained by the article and loads the content block into the corresponding content container. After determining the current page container and its corresponding content container, the content container is inserted into the page container. Since there is a blank line in the tail portion of the current page container, except for the last page container, the blank line of the current page container is filled by inserting the next content container immediately adjacent to the corresponding content container into the current page container. Compared with the prior art, when there is a blank line in the page after paging, the blank line can be filled, thereby avoiding the phenomenon of blank lines at the end of the page, improving the utilization of the page, and further optimizing the display effect and improving the user experience. .

Embodiment 2

Referring to FIG. 3, this figure shows a flow chart of a second implementation method of a page layout method according to an embodiment of the present invention. This embodiment is an extension of the first embodiment. For the content of the method in the embodiment, the content of the method is not described in detail in the embodiment. In this embodiment, the method includes the following steps:

Step S201: Determine the number of words that the terminal display area can accommodate.

In this embodiment, it is assumed that the article contains 1000 characters and the terminal display area can hold 100 words.

Step S202: The article is divided into a plurality of content blocks according to the number of words that the terminal display area can accommodate.

Starting with the first character of the article, every 100 characters as a block of content, get 10 blocks of content.

Step S203: Loading the content block into the corresponding content container.

Step S204: Determine the current page container and its corresponding content container.

On the basis of the foregoing embodiment, in this embodiment, the first page container corresponds to the first content container; the second page container corresponds to the second content container; and the third page container corresponds to the third content container, This type of push. Of course, the content of the end portion of the first content container is concatenated with the content of the beginning portion of the second content container; the content of the end portion of the second content container is concatenated with the content of the beginning portion of the third content container; Step backwards.

Step S205: Insert the content container into the page container.

Step S206: Insert the next content container immediately adjacent to the content container into the current page container.

Assuming that the current page container is a second page container, since there are two blank lines in the tail portion of the second page container after inserting the second content container, the third content container is inserted into the second page container to fill Two blank lines of the second page container. Of course, as can be seen from the above embodiment, in the second page container, only the content of the first line of the third content container can be displayed, and other parts cannot be displayed.

Step S207: Calculate the offset of the current page container.

Assuming that there are two rows of blank lines in the first page container, the first two lines of content in the first content container are displayed in both the first page container and the second page container, causing repeated display, not only wasting the page. Resources, and affect the user's experience. Therefore, in order to remove the portion of the repeated display, it is necessary to adjust the display area of the second content container in the second page container. In a preferred embodiment of the present invention, the height difference between the first page container and the first content container is obtained by calculation, and the offset of the first page container is obtained, and the second page container is used according to the offset. Adjust the content container. Similarly, there is also a blank line in the second page container, so the offset of the second page container needs to be calculated in order to typeset the subsequent page container.

Step S208: Accumulating the offset amount to obtain a cumulative offset.

On the basis of the foregoing embodiment, when the second content container in the second page container is offset upward by two lines, in order to ensure the content display, the third page container needs to be the third. Content container Offset two lines upwards. The second page container itself already has two blank lines, so the third content container repeats in the second page container, the offset of the first page container and the second page container. The accumulation of shifts. Therefore, it is necessary to accumulate all the previously obtained offsets to obtain a cumulative offset so as to process the subsequent page containers according to the accumulated offset.

Step S209: The next page container of the current page container is used as the current page container, and the display content of the content container in the current page container is adjusted according to the accumulated offset.

The adjusting the content of the content container in the third page container according to the offset includes: determining whether the accumulated offset is smaller than the height of the third content container; and when the cumulative offset is less than the height of the third content container In the third content container, only part of the content is displayed in the second page container, and other parts need to be displayed in the third page container, so the third content container in the third page container Offward shifts the portion of the third content container that is repeatedly displayed with the second page container out of the visible area while shifting the fourth content container in the third page container up by the same amount. When the cumulative offset is greater than or equal to the height of the third content container, the content of the third content container is all displayed in the second content container, thus deleting the third page container. Of course, when the 'current page container' is the last page container, the layout of the article ends.

In this embodiment, by calculating the offset of the repeatedly displayed content, and offsetting the repeated portion from the visible area of the page container according to the offset, the page container is removed on the basis of filling the blank area of each page container. The repeated display between the parts not only makes full use of the page resources, but also improves the user experience.

Embodiment 3

Referring to FIG. 4, a flow chart of a third implementation method of a page layout method according to an embodiment of the present invention is shown. This embodiment transforms the execution order of the above two embodiments to form the execution mode of the embodiment. The content of the implementation of this embodiment is similar to that of the foregoing embodiment. For the content of the method in this embodiment, which is repetitive with the first embodiment or the second embodiment, refer to the content of the first embodiment and/or the second embodiment. I won't go into details here. In this embodiment, the method includes the following steps:

Step S301: Determine the number of words that the terminal display area can accommodate.

Step S302: The article is divided into a plurality of content blocks according to the number of words that the terminal display area can accommodate.

Step S303: Load each content block into a corresponding content container.

Step S304: Insert each content container into a corresponding page container.

Step S305: In addition to the last page container, in each page container, the content container in the next page container is inserted.

In this embodiment, after inserting each content container into the corresponding page container, the last page container is removed, and the blank of each page container may be filled first; or, when the corresponding content container is inserted into the current page container, The next content container of the content container is inserted into the current page container.

Step S306: Determine the current page container.

Step S307: Typesetting the current page container.

If the current page container is the first page container, the current page container has been formatted, and the offset is determined by calculating the height difference between the current page container and the first content container; when the 'current page container' is not the first page container When not the last page container, calculate the height difference between the current page container and its corresponding content container, and then, according to the previously calculated offset, offset the content container in the current page container upward, and complete the current content container. Typography.

Step S308: Calculate the offset of the current page container.

Step S309: Accumulating the offset to obtain a cumulative offset

Step S310: The next page container of the current page container is used as the current page container, and the current page container is typeset according to the accumulated offset.

Step S311: determining whether the current page container is the last container, if not, executing step S308; when yes, executing step S312.

Wherein, when the 'current page container' is not the last page container, according to the above embodiment, the current page container has the same content as in the next page container, therefore, the offset needs to be calculated in order to obtain The offset is accumulated, and the subsequent page container is typeset according to the accumulated offset; when the 'current page container' is the last page container, all the page containers have completed the typesetting, and the operation ends.

In the page layout method provided in this embodiment, a plurality of content blocks obtained by paging the articles are loaded, and the content blocks are loaded into the corresponding content containers. After determining the current page container and its corresponding content container, the content container is inserted into the page container. Since there is a blank line in the tail portion of the current page container, except for the last page container, the blank line of the current page container is filled by inserting the next content container immediately adjacent to the corresponding content container into the current page container. Compared with the prior art, when there is a blank line in the page after paging, the blank line can be filled. Therefore, the phenomenon of blank lines at the end of the page can be avoided, the utilization of the page can be improved, and the display effect can be further optimized to improve the user experience.

Embodiment 4

In order to make the technical solutions of the present invention more clear to those skilled in the art, the technical solutions of the present invention are described in detail in this embodiment through a specific example.

In this embodiment, a Chinese article including 1000 characters is taken as an example. Assume that the electronic reading terminal is a mobile phone, and the height and width parameters of the display interface are known, and the font size when the character is displayed is known. First, the width of each character is calculated according to the relationship between the character size and the pixel; then, according to the width of the display interface of the mobile phone, the number of characters that can be accommodated in each line is calculated. It is assumed that in this embodiment, each line can accommodate 10 characters; finally, the number of lines that can be accommodated per page is calculated according to the height parameter of the display interface of the mobile phone. It is assumed that in the present embodiment, 10 lines can be accommodated, thereby determining that in the present embodiment, each page can accommodate 100 characters. 1000 characters can be divided into 10 pages.

Starting from the first character, a DOM node is inserted for every 100 characters, and the content of each page is represented by a DOM node. Specifically, a start node is added before the first character, and an end node is added after the first hundred characters, and the same operation is performed for every 100 characters in the following.

It should be noted that every 100 characters can be regarded as a content block, and the DOM node can be regarded as a content container of a package content block. In this embodiment, 10 content containers are included. In addition, in order to visually see the display effect of each content block on the mobile phone display interface, after determining to divide the article into 10 pages, 10 page containers are created, and each content container corresponds to one page container. The size of the display area of the page container is set according to the size of the display screen of the mobile phone.

The content container is sequentially inserted into its corresponding page container, as shown in FIG. 5-1, which shows a schematic view of the content container 51 being inserted into the page container 52. Each content container is inserted into the display area of the page container in the order of the content blocks, wherein the contents of the content blocks in any two adjacent page containers are connected to each other. It should be noted that after the content container 51 is inserted into the page container 52, the content block in the content container 51 controls the layout of the characters according to the CSS style, forming a natural typesetting in which the end of each line is aligned. Since there are half-width punctuation marks or English letters in the content of the article, after the content block is naturally typeset, a blank line appears at the end of the page container 52.

To fill the blank line that appears at the end of each page container, any page container other than the last page container is used as the current page container, and the content container in the next page container of the current page container is inserted into the current page container. First, before inserting, first determine the end node of the content container to be inserted first, secondly, the position immediately after the end node, and finally, the position to be inserted as the start node of the post-insertion content container. Need to say The first line of the content inserted in the content container is automatically followed by another line. Of course, if the current page container is the last page container, there is no need to fill in the blank lines at the end of its page.

As shown in Figure 5-2, the page container is displayed after the page container is blank. Each of the page containers includes two content containers, and the first inserted content container 53 is all displayed, and the post-inserted content container 54 is displayed only in the blank portion of the page container 52, and other portions are not visible.

If the current page container is the first page container, at this time, the page container is already filled, that is, the layout of the first page container has been completed; if the current page container is not the first page container, due to the current page container The content displayed by the previous page container contains the same content as the content displayed by the current page container. Therefore, in order to improve the utilization of the page, the same part of the current page container as the previous page container should be removed.

Please refer to Figure 5-3, which shows the display after the content of the page container is offset. In this embodiment, by shifting the content container, the repeated portion inserted into the content container 52 is moved from the visible area of the page container 52 to the invisible area, so that the content displayed by the current page container header is compared with the previous page. The content displayed at the end of the container is connected. It should be noted that, in order to ensure the consistency of the content displayed by the current page container, when the content container 52 is first shifted upward, the post-insertion content container 53 is also offset upward by the same amount, and thus the layout of the current page container is completed. .

In addition, in this embodiment, when the 'current page container' is the second page container, the height difference between the visible area of the first page container and the content container inserted first is calculated, and the height difference is the first page container needs. The filled blank area, the content displayed in the blank area is the height of the duplicate content in the current page container, so the height difference is determined as the offset of the content container in the current page container; when the 'current page container' is When the Nth (N is a natural number greater than 2) page containers, the height difference of the first N-1 page containers is obtained, and the N-1 height differences are accumulated to obtain the offset of the current page container. For example, when N is 3, the offset of the current page container is the sum of the difference between the height difference of the first page container and the height difference of the second page container, and the calculation of the offset of the other page containers is the same as the above, and the present invention I will not repeat them here.

It should be noted that before adjusting the content container according to the offset, it is determined whether the offset is smaller than the height of the content container inserted first in the current page container. If it is smaller, the content inserted in the content container is displayed in the previous page container. The rest of the content is displayed in the current page container, so the content container in the current page is adjusted according to the offset; if the offset is greater than or equal to the height of the content container first inserted, it means that all the content in the content container is inserted first. The previous page container is populated, that is, its entire content is displayed in the previous page container, so the current page container is directly deleted.

Of course, after inserting the content container into the corresponding page container respectively, you can first perform the operation of filling the blank line for each page container, then calculate the height difference of each page container separately, and adjust each page container separately until the end. A page container; or execute on the current page container, fill in the empty line, and then calculate the height difference operation, point to the next page container, and perform the same operation until the last container. The present invention is not limited to the specific order of execution.

It should be noted that the foregoing is only a preferred example of the present invention, and the technical solution of the present invention is not limited in any way. The simple deformation and replacement of each execution step belong to the protection scope of the technical solution of the present invention.

In the page layout method provided by the embodiment of the present invention, a plurality of content blocks obtained by paging the articles are obtained, and the content blocks are loaded into the corresponding content containers. After determining the current page container and its corresponding content container, the corresponding content container is inserted into the page container. Since there is a blank line in the footer portion of the current page container, the blank line of the page container is filled by inserting the next content container immediately adjacent to the corresponding content container into the current page container. Compared with the prior art, when there is a blank line in the page after paging, the blank line can be filled, thereby avoiding the phenomenon of blank lines at the end of the page, improving the utilization of the page, and further optimizing the display effect and improving the user experience. .
