As shown in fig. 4, fig. 4 is a computer-side signing diagram of a method for rendering workflow electronic forms by using a reader for secure parsing, where the reader at the computer side can select an enterprise inspection application form for opening than a handwriting device for signing.

As shown in fig. 5, fig. 5 is a schematic diagram of mobile terminal signing in a method for rendering an electronic form of a workflow by secure parsing through a reader, where a reader page of a mobile terminal may select an enterprise inspection application form to open and sign through a touch screen.

As shown in fig. 6, fig. 6 is a mobile terminal multi-page signing diagram of a method for rendering workflow electronic forms by secure parsing through a reader, where a reader page of a mobile terminal may select multiple enterprise inspection application forms to open and perform signing through page turning on a touch screen.

The steps of signing at the computer end and the mobile end are the same, an analysis module of the reader opens a text of an enterprise checking application form, the analysis module strips elements such as a primary title, a secondary title, a text, a header, a footer and a background of the text to form a plurality of element queues, simultaneously analyzes page information such as the length and the width of the text and stores the page information into a storage module, then the analysis module calls a resource package to analyze a plurality of element resource packages, and takes a certain basic element TD (common text) of the page as an example, the element package of the basic element TD can analyze a rendering pattern of the basic element TD (common text), so that patterns such as the font, the size, the color and the format of the text can be selected in a customized manner, and the corresponding element patterns are distributed into attributes of the element queues after the selection is completed.

And a rendering module of the reader generates a blank text with the same size as the check application form according to the page information, generates a traversal array from all the element queues, executes traversal one by one from the first of the array, and draws the selected element attributes in the blank text according to the format of the original text. Because basic elements are more and the rendering time is longer, the rendering module can acquire the number of the total elements before rendering, and when the rendering style is loaded, a progress bar is generated according to the ratio of the number of the completed elements to the number of the total elements, so that the rendering progress can be known in real time. And when the rendering is finished, generating a rendering text, and displaying the rendering text according to the style of the initial text.

When the rendering module loads the electronic form, the rendering module can carry out memory management on the displayed electronic form resource and is used for reasonably displaying the dynamic file.

And adding related interface operation events such as an acquisition focus and the like aiming at an input box of the transactants in the inspection application form, binding script methods such as JS (JavaScript) and the like into corresponding elements, and adding the name of the transactants into the input box of the transactants to display after adding the name of the transactants into the JS.

When the user inputs more names of the transactor input boxes, the rendering module can calculate whether the input names exceed the preset height in real time; if the height is smaller than the preset height, keeping the height unchanged; and if the input content exceeds the preset height, automatically extending the rendered page.

The encryption signature module of the reader adopts a handwriting pen or a hand to perform relevant handwriting operation in a designated area aiming at a blank area needing handwriting (such as a signature area).

For example, in the event of important items of the office content and the reply content in fig. 5, circles are drawn and written for annotation to emphasize the importance of the important items and remind the specific implementer of the important items.

After signing is finished, when storage is executed, signing and encrypting the content page content to ensure that the related reading information and signing information are not tampered and cannot be repudiated; and the storage module of the reader carries out remote storage so as to facilitate the next direct reading.

The foregoing is only a preferred form of the invention and it should be noted that several similar variations and modifications could be made by one skilled in the art without departing from the inventive concept and these should also be considered within the scope of the invention.
