In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Example 1:
fig. 1 shows an implementation flow Of a division printing method provided by an embodiment Of the present invention, where a flow execution subject Of this embodiment may be a transaction terminal, and the transaction terminal includes a payment terminal, a cash register terminal, and the like, for example, a pos (point Of sale) terminal, an ATM device, and the like.
As shown in fig. 1, a method for division printing according to an embodiment of the present invention includes:
step S101, creating a DOM element containing printing information, and creating an HTML transaction document according to the DOM element;
wherein the HTML transaction document includes a DOM element and transaction information.
Step S102, judging whether an unprinted node exists in the HTML transaction document, if so, segmenting the DOM element according to a preset sequence, and acquiring a printing element meeting the requirement;
the unprinted node refers to content which is not printed in the HTML transaction document.
The embodiment judges whether unprinted nodes exist in the HTML transaction document, if so, the steps S102-S103 are sequentially executed, and if not, the method indicates that all documents are printed and directly ends.
And step S103, combining the printing elements into a printing template, and printing the printing template by calling printing equipment.
In this embodiment, the segmentation printing is successively completed, and after the segmentation is completed once and the printing template is formed for printing, the printed DOM elements are deleted from the HTML transaction document.
After the execution of step S103 is completed, the process again proceeds to step S102 to determine whether or not there is an unprinted node. If so, steps S102-S103 are repeated. If not, the printing of all the documents is finished, and a transaction list is obtained. The transaction order may be a transaction voucher, a transaction report or transaction detail, etc.
According to the embodiment of the invention, the DOM elements containing the printing information are created and are divided to form the printing template for printing, so that the divided printing is realized, the data volume of each printing is reduced, and the problem of abnormal printing of hardware equipment is solved; the method of combining the printing templates simplifies the complexity of typesetting, organization and the like of the printing templates, so that the printing contents are concise and beautiful, and the user experience is improved.
In one embodiment of the present invention, step S101 includes:
1) creating the DOM element containing the printing information;
2) and wrapping the DOM element containing the printing information by using a standard IFrame to obtain a wrapped DOM element, and putting the wrapped DOM element into a Document object to obtain the HTML transaction Document.
In this embodiment, the HTML is HyperText Markup Language and HyperText Markup Language, and is used to organize web page contents, including text, pictures, audio/video contents, and provide semantic tags such as links, paragraphs, and lists. The HTML transaction document is a graphical page file, and the HTML transaction document in this embodiment includes transaction order data information.
Each HTML transaction Document has a Document object available that allows a user to access all of the elements in the HTML transaction Document from the script.
The DOM is the Document Object Model. The DOM elements define the objects and attributes of the elements in the HTML transaction document, as well as the methods of accessing them. By using the DOM element, operations of obtaining, modifying, adding or deleting the HTML transaction document can be realized.
In one embodiment of the present invention, after step S101, the division printing method further includes:
and setting the attribute of the DOM element in the HTML transaction document to be invisible, and acquiring the height of the DOM element.
In this embodiment, the DOM element is set to be invisible, so as to prevent a CSS (Cascading Style Sheets) Style of the printed DOM from affecting the layout Style of Document, thereby affecting the acquisition of the actual height of the DOM element.
In one embodiment of the invention, the segmenting the DOM element in step S102 comprises:
1) combining the size of the printing buffer area and the user requirement, and testing to obtain the length of the printing area;
2) analyzing the DOM elements according to the preset sequence to obtain critical points which accord with the length of the printing area;
3) analyzing the critical point according to the length of the printing area and the height of the DOM element to obtain a segmentation position;
4) and segmenting the DOM element according to the segmentation position to obtain the printing element.
In one embodiment, the size of the print buffer of the transaction terminal and the user best experience data are combined, and the length of the print buffer is estimated to be more appropriate after relevant tests are performed.
The DOM element is composed of a plurality of nodes and is divided into a father node and a child node, and each father node comprises a plurality of child nodes.
For example, starting from the first child node of the first-layer parent node of the DOM element, the idea of layer-by-layer analysis from top to bottom is adopted, and if the height from the starting position to a certain node just meets the length of the printing area, the node is a critical point. Analyzing the critical point, considering the requirements of a user on the simplicity, the attractiveness and the like of a printing interface, if the critical point is taken as a printing node and does not meet the requirements, analyzing the nodes near the critical point until the maximum limited printing length is reached and the user requirements are met, and taking the nodes as the segmentation positions.
In one embodiment, the combining of the print elements into a print template in step S103 comprises:
and combining the template container with the printing elements to obtain the printing template.
It will be appreciated that the print elements are filled into the template container, resulting in a printed document for printing, i.e. a print template. The print template may be used to print a ticket.
The template container is fixed, and the printing elements are filled into the template container to obtain a printing template for printing. The method for combining the template container and the printing element comprises VUE template grammar, a data binding mechanism and the like. The complexity of typesetting, organization and the like of the printing template is greatly simplified.
In one embodiment of the present invention, after step S103, the division printing method further includes:
and after printing is completed, clearing the DOM element containing the printing information from the HTML transaction document.
The deletion function of the DOM element is set in the initial Document, and the function is started after printing is finished, so that the content in the Document can be reduced, the file is lighter, and various influences caused by data redundancy are avoided.
In this embodiment, after each time the divided printing of the DOM element is completed and deleted, the above entire flow is repeated for the unprinted nodes.
According to the embodiment of the invention, the divided printing method based on the HTML technology is adopted, so that the capacity limitation of the printing cache region of the hardware equipment and the limitation of the length of the transaction list are solved, the complexity of typesetting, organizing and the like of the printing template is simplified, the printing abnormity can be reduced, and the user experience is improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
