Description

A Method of Printing Document Pages Based on HTML Tags

technical field

The invention relates to the technical field of mobile law enforcement document printing, in particular to a method for page-by-page printing of documents based on HTML tags.

Background technique

In the process of on-site law enforcement, law enforcement officers need to take notes according to the on-site law enforcement situation, and save the contents of the notes locally on the mobile terminal, and then connect the mobile terminal to a printer to print out the content as evidence for filing or filing a case.

At present, the transcript content of on-site law enforcement is generally stored in HTML pages, and the transcript content is stored in one or more HTML pages by setting the height and number of lines of each HTML page, as well as the number of words in each line. Specifically, if the number of characters of the on-site law enforcement situation is less than the number of characters that can be accommodated in one page, the content of the transcript will be displayed on one page; After satisfying the set height, number of lines and number of words per line, continue to fill in the next page, thus realizing pagination.

However, since the content of the on-site law enforcement transcript is filled in according to the actual situation of the on-site law enforcement, there are no regulations or restrictions on the number of words or the type of characters. In the same law enforcement transcript, many different types of characters may be involved. Since different types of characters have different occupancy sizes, use the above method to perform pagination after the conditions are met according to the set page height, number of lines and words. If the printed text contains more numbers or characters during pagination, Then each line is still calculated according to the fixed number of words, and there will be a situation where one line cannot be filled, resulting in blanks in some positions on the front pages, and no characters are displayed, resulting in irregular pages after printing.

Contents of the invention

The purpose of the present invention is to provide a method for page-by-page printing of documents based on HTML tags, so as to solve the aforementioned problems in the prior art.

In order to achieve the above object, the technical scheme adopted in the present invention is as follows:

A method for page-by-page printing of documents based on HTML tags, comprising the following steps:

S1, filling the content of the document to be printed into the HTML tag;

S2, setting a paging container in each paging page, setting the height of the paging container according to the height of the HTML tags that can be displayed in each paging page, and the height of the paging container is the same as that of the displayable HTML tags in the paging page HTML tags have the same height;

S3, setting the OverFlow attribute and the Position attribute of the paging container in each paging page;

S4. According to the OverFlow property and the Position property of the paging container, fill the HTML tags into all the paging pages.

Further, after S1, a step of calculating the height of the HTML tag is also included.

Furthermore, between S3 and S4, there is also a step of calculating the number of paging pages according to the height of the HTML tag and the height of the paging container.

Wherein, the calculation of the number of paging pages according to the height of the HTML tag and the height of the paging container specifically includes the following steps:

Compare the height of the HTML tag with the height of the paging container in the first paging page, if the height of the HTML tag is less than the height of the paging container in the first paging page, then the paging page The number is 1; if the height of the HTML tag is greater than the height of the paging container in the first paging page, then count the number of the paging pages.

Wherein, if the height of the HTML tag is greater than the height of the paging container in the first paging page, then calculate the number of the paging pages, specifically, if all the paging containers in the paging page If the heights are all equal, divide the height of the HTML tag by the height of one paging container to obtain the number of paging pages; if the heights of the paging containers in the paging pages are not equal, start from the first The pagination container starts with the pagination page and counts the number of pagination pages.

Specifically, for page-by-page printing of HTML documents of law enforcement documents, the height of the page-by-page container is obtained by the following method:

Obtain the height of the paging page where the paging container is located;

Obtain the height of the fixed template in the pagination page;

The height of the paging container is obtained by subtracting the height of the fixed template from the height of the paging page.

Preferably, the height of the paginated pages is the height of A4 printing paper.

Preferably, the fixed templates in the first paginated page include a top fixed template and a bottom fixed template; the fixed templates in the second to nth paginated pages are bottom fixed templates.

Preferably, the HTML tag is TR, TD or div.

Preferably, the paging container is div.

The beneficial effects of the present invention are: the method for page-by-page document printing based on HTML tags provided by the embodiment of the present invention firstly fills the transcript content into the HTML tag, completely displays the transcript content in the HTML page, and then, by calculating the page-by-page The height of the paging container that can be filled with content, set the hidden attribute and position attribute of the paging container, so that part of the content of the corresponding HTML tag is displayed in the paging container of each paging page, and other content is hidden, so that by using HTML The hidden attribute of the label realizes page-by-page printing of the transcript content, and fills each page-by-page to make the page-by-page more beautiful without blanking, and solves the problem of irregular page-by-page printing files in the prior art .

detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

As shown in Figure 1, the embodiment of the present invention provides a method for page-by-page printing of documents based on HTML tags, including the following steps:

S1, filling HTML tags with the content of the document to be printed. In actual operation, in order to be able to display the complete document to be printed in one HTML page, set the attribute of the HTML tag to not hide, so that the complete document to be printed can be displayed instead of only displaying a part and hiding a part.

For law enforcement documents, in this application, the document to be printed is the transcript content generated according to the situation of the law enforcement scene. Both the top fixed template and the bottom fixed template in the law enforcement document are set as templates, and can also be directly displayed in the HTML page.

S2, setting a paging container in each paging page, setting the height of the paging container according to the height of the HTML tags that can be displayed in each paging page, and the height of the paging container is the same as that of the displayable HTML tags in the paging page HTML tags have the same height; .

In the present invention, since the paginated pages need to be printed by the printer, the height of the paginated pages is set according to the height of the printing paper used. As those skilled in the art can understand, the height can be default or set according to requirements of. However, the height of the HTML page is determined according to the on-site record content filled in its tags. If there is more content, the height of the HTML tag will be larger, and vice versa, the height of the HTML tag will be smaller.

The pagination container is also a kind of HTML tag. By setting its OverFlow property, the paging of the label can be realized, and it can be used to display the content of the page in different paging pages. By setting its Position property, the positioning of the content in the paging container can be realized.

As those skilled in the art can understand, if there is no other content within the height of the paging page, the height of the paging container is the height of the paging page, and if other content is to be displayed within the height of the paging page, the height of the paging container is The height of the paginated page minus the height occupied by other content.

S3, setting the OverFlow attribute and the Position attribute of the paging container in each paging page;

S4. According to the OverFlow property and the Position property of the paging container, fill the HTML tags into all the paging pages.

In the present invention, by setting the hidden attribute and position attribute of the HTML tag, the content of the document to be printed in the HTML tag is displayed on different paging pages. When working specifically, first calculate the height of the paging container set in each different paging page, calculate the content of the HTML tags that can be displayed in the paging page according to the height of the paging container, and set the hidden attribute of the HTML tag. The content of the height of the HTML tag corresponding to its height is displayed in the paging container, while other content is hidden. As those skilled in the art can understand, the hidden attribute of the HTML tag itself has. In the present invention, it is more ingenious The hidden attribute is used in document paging printing; and by setting the position attribute of the HTML tag, different paging pages can display the content of the HTML tag of the corresponding height, and hide other content, so as to realize pagination. In the process of paging, according to the height of the paging container in different paging pages, the hidden attribute of the HTML tag is used to display the content of the corresponding height and hide the content of other heights. Therefore, in the paging process , does not involve the process of fixing the number of characters per page according to the number of lines and the number of words in each line, and paging after the number of characters is satisfied, so the paging container will be filled without blank pages.

In the embodiment of the present invention, after S1, a step is further included to calculate the height of the HTML tag.

Through this step, it is possible to know the amount of on-site law enforcement transcripts. If there are many transcripts, a larger height value of the pagination page can be set; otherwise, a smaller height value of the pagination page can be set.

In this embodiment, between S3 and S4, a step is further included to calculate the number of paging pages according to the height of the HTML tag and the height of the paging container. Specifically, the following methods can be adopted, including the following steps:

Compare the height of the HTML tag with the height of the paging container in the first paging page, if the height of the HTML tag is less than the height of the paging container in the first paging page, then the paging page The number is 1; if the height of the HTML tag is greater than the height of the paging container in the first paging page, then count the number of the paging pages.

Wherein, in this embodiment, if the height of the HTML tag is greater than the height of the paging container in the first paging page, then calculate the number of the paging pages, specifically, if all the paging pages The heights of the paging containers are all equal, then divide the height of the HTML tag by the height of one paging container to obtain the number of the paging pages; if the heights of the paging containers in the paging pages are not equal, Then start from the paging container of the first paging page to calculate the number of paging pages. For example, the height of the HTML tag is 200, the height of the paging container of the first pagination page is 50, and the height of the paging container of the second paging page to the nth paging page is 100, then the content of the HTML tag is filled To the paging page, you need to add 1 to (200-50)/100, that is, 3 paging pages.

In the embodiment of the present invention, for the page-by-page printing of the HTML document of law enforcement documents, the height of the page-by-page container is obtained by the following method:

Obtain the height of the paging page where the paging container is located;

Obtain the height of the fixed template in the pagination page;

The height of the paging container is obtained by subtracting the height of the fixed template from the height of the paging page.

Law enforcement documents have a fixed format. For example, at the beginning of the law enforcement document, it is necessary to record the time and place of law enforcement, the information of the law enforcement person and the person subject to law enforcement, and the description of law enforcement to form a fixed template at the top. At the end of the law enforcement document, law enforcement documents need to be The person's signature and the person's signature, etc., form a fixed template at the bottom.

If there is a top fixed template and a bottom fixed template, or a bottom fixed template in the paging page, its height needs to be removed to obtain the height of the paging container, and the height of the paging container is used to display the content of the HTML tag of the corresponding height.

In the embodiment of the present invention, the fixed templates in the first paginated page include a top fixed template and a bottom fixed template; the fixed templates in the second to nth paginated pages are bottom fixed templates.

In order to make the law enforcement documents more standardized and make each pagination page have legal benefits, in this embodiment, a bottom fixed template is set in each pagination page; and in order to simplify the law enforcement documents, in this embodiment, only the first The top pinned template is displayed in the pagination page.

Then, in the first paging page, the height of the paging page is subtracted from the height of the top fixed template and the height of the bottom fixed template; in the second to nth paging pages, the height of the paging container is the height of the paging page minus The height of the bottom fixed template, the height of the pagination container.

Wherein, the height of the pagination page is the height of A4 printing paper.

Using A4 printing paper can make law enforcement documents more standardized and beautiful.

In the embodiment of the present invention, the HTML tag is TR, TD or div.

In the embodiment of the present invention, the paging container is div.

As those skilled in the art can understand, the height of the div can be set, and the Overflow property can be set according to the height. After these two properties are set, the text exceeding this height will be hidden.

The specific process of paging printing of law enforcement documents can be as follows:

(1) Obtain the height of the paging container on the first page: subtract the header and footer according to the size of the A4 paper to obtain the height of the paging container of the paging page.

(2) Obtain the height of the paging container from page 2 to page N: the height of the paging container from page 2 to page N is the height of the A4 paper minus the height of the footer.

(3) Calculate the number of pages for paging: fill the content of the on-site law enforcement transcripts into HTML tags without hidden attributes, and obtain the height of the HTML tags. If the height of the obtained HTML tags is smaller than the height of the paging container on the first page, then display one page The content does not need to be paginated; if it is greater than the height of the paging container of the first page, the number of pages other than the first page is obtained by dividing the height of the greater part by the height of the paging container from the second to the Nth page. Total number of pages.

(4) Control of the display content of each paging page: fill all the content in the HTML tag in the paging container, control the hiding of the excess content through the height of the paging container and the OverFlow property, display the content of the corresponding height, and pass the property of the paging container Position is used to determine the content display position in the paging container to control the display content of different pages.

Adopt the method for page-by-page printing of documents based on HTML tags provided by the embodiment of the present invention, when the scene content is too much, page-by-page is performed, and each page has legal benefits. For law enforcement personnel, this record has authenticity and portability; and It can make the interface of the on-site record more beautiful and enrich the content; make the whole law enforcement process more standardized and formalized.

By adopting the above-mentioned technical solution disclosed in the present invention, the following beneficial effects are obtained: the method for page-by-page printing of documents based on HTML tags provided by the embodiment of the present invention firstly fills the transcript content into the HTML tag, and completely displays the transcript content in the In the HTML page, then, by calculating the height of the paging container that can be filled with content in the paging page, setting the hidden attribute and the position attribute of the paging container, thereby displaying part of the content of the corresponding HTML tag in the paging container of each paging page, and Hide other content, so that the page-by-page printing of the transcript content is realized by using the hidden attribute of the HTML tag, and each page-by-page is filled to make the page-by-page more beautiful without blanking, which solves the problem There is a problem that the pagination printing file is not neat in the technology.
