Abstract

The invention provides an OFD document webpage end browsing method and system, and the method comprises the steps: a browser transmitting an OFD document identification to a server, and the server returning the page structure information of an OFD document to the browser; and the browser grouping the OFD documents according to the received information, generating HTML tags of all groups, and generating HTML tags containing pages under the current group; if the current page is the nth page, the browser querying whether the (n-1)th page, the nth page, the (n + 1)th page and the (n + 2)th page are loaded or not in a browser cache, if yes, not processing, and if not, requesting corresponding page data to be loaded to the server. An asynchronous loading mode is adopted, loading is carried out according to needs, waiting time of a browser end is shortened, an HTML document structure is simplified, rendering pressure of a browser can be reduced, and response speed of the browser is improved.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a method and system for browsing an OFD document on a web page. Background technique [0002] For a long time, most of my country's formatted electronic documents use foreign software products and foreign standards, such as the PDF (Portable Document Format) portable document format that is often used in daily work.

AI Technical Summary

Problems solved by technology

[0012] 1. The opening of the webpage is slow, especially for OFD documents opened for the first time and with a large number of pages. Due to the long parsing time of the server, the waiting time will be very long;

[0013] 2. The page turning is stuck and not smooth, especially for documents with a large number of pages, such as documents with thousands of pages, the page turning experience is quite poor;

[0014] 3. The HTML page document structure is complex and multi-layer nested, which will occupy too much browser memory, make the browser very stuck, and even cause the browser to crash;

[0015] 4. The server needs to decompress the OFD document first, and then parse it. For documents with a large number of pages, the decompression time will be longer;

[0016] 5. Synchronously parse all the pages of the OFD document, the first loading will be very slow, and cause a lot of pressure on the server
