First, a structured document synchronization page is provided, wherein the first area includes a plurality of forms, and the second area receives uploaded structured documents and converts the structured documents into files in a web page format. The files in the web page format contain a plurality of bookmarks. When the form content in the first area is modified, the first web page communication tool is called to transmit the modified content, and then the modified content is received through the second web page communication tool. After receiving the modified content, the bookmark corresponding to the second area is modified through an event handler. Through the web page communication tool and the event handler, the user can operate on one side and make modifications on the other side at the same time, without downloading documents and repeatedly uploading documents. By sharing online documents, cross-platform document online processing is performed. In business work, the application effect is significant and office efficiency is improved.

[0038] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0039] First, one or more embodiments of the present disclosure provide a key unit synchronization method for a structured document. Figure 1 , the method comprises the following steps:

[0040] Step S101: providing a synchronization page including a first area and a second area on a user interface.

[0041] In the embodiment of the present disclosure, a synchronization page is provided on the user interface, including a first area and a second area.

[0042] Step S102, displaying a form including multiple key fields in the first area, wherein the content in each of the key fields is extracted from a database of the business system using an identifier of the structured document and an identifier of the key field. For example, the multiple key fields may include structured key fields used to create the structured document according to the needs of the business system.

[0043] Step S103, in response to detecting a predetermined operation of the user on the user interface, based on a plurality of bookmark attributes maintained in advance according to the plurality of key fields, converting the structured document into a web page format file including the plurality of bookmark attributes through a document parsing engine, and displaying the web page format file in the second area.

[0044] In the present disclosure, Figure 3 As shown, the user can maintain the bookmark attribute in advance according to the key field of the structured document, and the bookmark attribute name is consistent with the key field name of the form in the first area. The second area of ​​the synchronization page can receive the uploaded structured document, convert the structured document into a web page format file including the maintained bookmark attribute through the document parsing engine, store the web page format file in the server, and display the web page format file in the second area.

[0045] The user can maintain the bookmark attributes according to the key fields of the structured document in advance, which can ensure the uniqueness of the bookmark attribute name and the association between the bookmark attribute and the key fields of the form in the first area, providing a basis for document synchronization and ensuring the accuracy of document synchronization. The document conversion is performed using the existing document conversion engine, and a web page format file can be directly generated without manual conversion.

[0046] Specifically, as an optional manner, the document parsing engine may be a cross-platform document parsing engine OpenOffice, and the web page format file includes a hypertext markup language HTML format file.

[0047] After obtaining the structured document through the document parsing engine, it can be converted directly without the user having to consider the specific steps and format of the conversion, saving the user's time and being convenient and quick.

[0048] OpenOffice document parsing engine contains many tools, such as word processing like Word, making simple graphics, powerful chart functions, web page editing, mathematical symbols that are difficult to handle in MS Office, etc. It supports XML, Microsoft doc, Excel, ppt file formats, etc. It has integrated pdf output function.

[0049] Step S104, in response to a first event triggered by a user modifying a first content of a first key field among the multiple key fields in the first area monitored by the web multi-threaded tool, sending a first identifier of the first key field and the modified first content to a second web communication tool through the first web communication tool.

[0050] Specifically, as an optional method, the web page multithreading tool is Web Workers. The first web page communication tool is postMessage, and the second web page communication tool is onmessage. postMessage and onmessage are tools of HTML5, which are used to solve cross-page communication. postMessage is the sender, and onmessage is the receiver.

[0051] In the disclosed embodiment, Web Workers are used to provide a method for scripts on Web front-end web pages to run in a background process. Once it is created, Web Workers can send messages through the postMessage tool, and the other side can use the onmessage tool to receive messages. The Web Workers process can process tasks without affecting the user interface. When a user modifies the key fields in the first area of ​​the synchronization page, Web Workers can directly monitor the user's modifications to certain key fields. For example, when the structured document is a contract document, the key fields are the name of the goods, the amount of the goods, the name of the contract, and the amount of the contract. Then the first identifier of the first key field and the modified content are sent to the onmessage tool through the postMessage tool. Among them, the first identifier is the name of the key field, such as contract_name, contract_price, etc. The onmessage tool receives the message, and after successful reception, the data synchronization operation can be performed. Through the web communication tool, data can be transmitted across regions, and the data of the first region can be sent to the second region, providing a basis for data synchronization.

[0052] Step S105, returning a message including the received first identifier and the modified first content to a pre-specified event handler through the second web page communication tool, so that the event handler determines the first bookmark attribute corresponding to the first identifier among the multiple bookmark attributes, and modifies the second content in the first bookmark attribute in the second area according to the modified first content.

[0053] In the disclosed embodiment, the onmessage tool receives a message of a first identifier and a modified first content, and returns the message to a pre-set event handler. The event handler can determine a second identifier corresponding to the first identifier through the received message, where the second identifier is contract_name, contract_price, etc., find the corresponding first bookmark attribute according to the second identifier, and then modify the corresponding content of the first bookmark attribute according to the received message of the modified content.

[0054] Optionally, the method also includes the following steps: in response to a second event triggered by a user modifying a third content of a second bookmark attribute among the multiple bookmark attributes in the second area monitored by the web multi-threaded tool, sending a second identifier of the second bookmark attribute and the modified third content to the second web communication tool through the first web communication tool; returning a message including the received second identifier and the modified third content to the event handler through the second web communication tool, so that the event handler determines a second key field among the multiple key fields corresponding to the second identifier, and modifies the fourth content in the second key field in the first area according to the modified third content.

[0055] When the user modifies the key fields of the second area of ​​the synchronization page, Web Workers can directly monitor the user's modification of certain key fields, and then send the bookmark attribute name and the modified content of the second key field to the onmessage tool through the postMessage tool. The onmessage tool receives the message, and after successful reception, the onmessage tool receives the message of the second identifier and the modified third content, and returns the message to the pre-set event handler, which can determine the first identifier corresponding to the second identifier through the received message, find the first key field according to the first identifier, and then modify the content of the first key field according to the received message of the modified content.

[0056] The following takes the synchronization of contract document content as an example. Figure 2 The key unit synchronization method of the structured document disclosed in the present invention is described.

[0057] The user modifies the contract name field in the first area of ​​the provided synchronization page to an order contract. Web Workers monitor the modification of the contract name field and send contract_name and the order contract to the onmessage tool through the postMessage tool. The onmessage tool returns the received contract_name and order contract messages to a pre-specified event handler, so that the event handler determines the first bookmark attribute named contract_name and modifies the content of the first bookmark attribute named contract_name in the second area to an order contract.

[0058] You only need to modify the key fields in the first area to automatically synchronize and modify the same key fields in the second area, realizing cross-regional message transmission and synchronization, avoiding time-consuming and tedious manual comparison and modification, and making data synchronization more efficient and accurate.

[0059] Based on the same inventive concept, corresponding to any of the above-mentioned embodiment methods, the present disclosure also provides a key unit synchronization device for a structured document.

[0063] The document conversion and display module 403 is used to: in response to detecting a predetermined operation of the user on the user interface, based on a plurality of bookmark attributes maintained in advance according to the plurality of key fields, convert the structured document into a webpage format file including the plurality of bookmark attributes through a document parsing engine, and display the webpage format file in the second area;

[0064] The first sending module 404 is configured to: in response to monitoring through the webpage multithreading tool a first event triggered by a user modifying a first content of a first key field among the multiple key fields in the first area, send a first identifier of the first key field and the modified first content to a second webpage communication tool through the first webpage communication tool;

[0065] The first synchronization modification module 405 is used to return a message including the received first identifier and the modified first content to a pre-specified event handler through the second web page communication tool, so that the event handler determines the first bookmark attribute corresponding to the first identifier among the multiple bookmark attributes, and modifies the second content in the first bookmark attribute in the second area according to the modified first content.

[0066] Optionally, the key unit synchronization device of the structured document may further include:

[0067] a second sending module, configured to: in response to monitoring by the webpage multithreading tool a second event triggered by a user modifying a third content of a second bookmark attribute among the plurality of bookmark attributes in the second area, send a second identifier of the second bookmark attribute and the modified third content to the second webpage communication tool through the first webpage communication tool;

[0068] The second synchronization modification module is used to return a message including the received second identifier and the modified third content to the event handler through the second web page communication tool, so that the event handler determines the second key field corresponding to the second identifier among the multiple key fields, and modifies the fourth content in the second key field in the first area according to the modified third content.
