Ofd file merge display and directory generation method

Abstract

The invention discloses a method for merging and displaying OFD files and generating a directory. The client traverses several OFD files, then copies several OFD files into a new file directory, and decompresses them; reads the files under the decompressed OFD folder , to obtain the file path of the folder, splice several OFD file page number information and content information into a JSON array; parse the file data of the JSON array, and organize the file directory; each directory in the file directory hyperlinks a file address path, click Each directory loads corresponding files; initializes the height of the scroll bar in the display area of ​​the client, and reads multiple OFD files across pages and files. The present invention does not destroy the original OFD files. On the basis of ensuring the independence of multiple OFD files, the file data is used to reorganize the new directory and a directory display tool is added. Multiple OFD files are directly displayed without opening OFD files one by one. The overall reading experience is effectively improved.

Description

technical field [0001] The invention relates to a method for merging and displaying files and generating a directory, in particular to a method for merging and displaying OFD files and generating a directory, and belongs to the field of computer software. Background technique [0002] On October 14, 2016, World Standards Day, the National Standardization Management Committee officially approved the release of the national standard GB / T 33190-2016 "Electronic File Storage and Exchange Format Format Document" (OFD) based on independent technology.

Problems solved by technology

At the same time, when multiple OFD files need to be combined and read, the existing reader breaks up the multiple OFD files and reassembles them into one OFD file. In this way, the original OFD file is destroyed every time it is read, and the user needs to keep backing it up. To ensure that the original file is not damaged, the operation is extremely cumbersome
