Abstract

The invention discloses an AJAX-based method for importing / exporting a large file into / from a web page on line. AJAX technology and DHTML are adopted, so that the page can be partially refreshed. Simultaneously, a mode of circularly transmitting a short request for multiple times is adopted so as to effectively lighten the burdens of processing and accessing the large file and inserting a database on a server and the burden of exporting a large amount of data by inquiring the database. Due to the adoption of the method, the problem of over time when the large file is imported into the database through the web page and the large amount of data is exported from the database through the web page in the prior art is solved, the limit that an imported application program or service cannot be written on a background without the authority of installing the application program on the server in the prior art is avoided and the aim of overcoming the defects of importing / exporting the large file into / from the web page on line is fulfilled.

Description

technical field [0001] The invention relates to AJAX web page technology, in particular to an AJAX-based method for online importing / exporting large files of web pages. Background technique [0002] With the continuous development of the Internet, the traditional dynamic webpage development technology has become familiar to many webpage producers. High requirements, traditional technology can no longer meet the needs of RIA development, and AJAX (Asynchronous JavaScript and XML, referred to as AJAX) began to become the mainstream RIA development model. AJAX is a programming technology that combines DHTML technology, XML (Extensible Markup Language, eXtensible Markup Language) and JavaScript. It is a combination of several technologies in a certain way to play their respective roles in common collaboration. AJAX is a web application development technology that uses client-side scripts to exchange data with web servers. In this way, web pages can be dynamically updated witho...
