Abstract
The invention provides a method for transforming and displaying a document on a webpage. The method comprises the following steps: a Web server receives an uploaded document to be transformed, runs a document transformation detection function, and recursively detects whether a transformation state document exists in a Web server returned document transformation directory. A document transformation server acquires the document to be converted from the Web server, calls a portable document format (PDF) transformation tool to acquire and store a PDF document, and returns to an absolute path of the PDF document. The document transformation server calls a small web format (swf) transformation tool which converts the PDF document into a swf document according to the absolute path of the acquired PDF document. The Web server acquires the transformation state document which is positioned in the document transformation directory. After the document transformation detection function detects that the transformation state document exists in the Web server returned document transformation directory, the transformation state document is analyzed, and the swf document acquired by transformation is played on the webpage according to the transformation state document.
