Specifically, formats other than the format of the pdf are converted to the format of the pdf, which is then converted to the swf format, and if the document format is already the pdf, no conversion to the pdf is necessary. As shown in FIG. 2, various types of documents may be converted to SWF files using a pdftoswf.jar conversion tool, which is one of the SWF Tools, and played using a document reader. After conversion, each page of original document is converted into one swf file.
Step 104: and loading a target swf file in the at least one swf file in response to a browsing request of a user. The target swf files comprise swf files corresponding to current pages browsed by a user, and first preset number of pages before the current pages and/or second preset number of pages after the current pages.
In the case that the user uses the terminal to open the document for reading and browsing, the user clicks the document or otherwise issues a browsing request, and the server loads the target swf file in the generated swf file. Firstly, loading swf files corresponding to the first page number and the preset number of page numbers. Under the condition that a user inputs a page number switching command, designating a page number to be hopped to, and loading swf files corresponding to the page number to be hopped to and the page numbers preset before and after. When the user browses the swf file of the last page, the swf file of the last page is loaded and the swf files corresponding to the preset number of pages. The first preset number may be the same or different from the second preset number, for example, the first preset number is 1 and the second preset number is 2.
