Abstract

The invention discloses a partial updating method based on an Ajax webpage. The method includes the steps of clicking a button for refreshing of a browser to obtain updated content, processing the updated content with an MSXML to create an XMLHttpRequest object, updating partial content of the webpage, sending a request to a background, building an xmlHttp and waiting a server to respond. When the attributive value of the xmlHttp is 4, it is indicated that the request is finished, a corresponding ready state is reached, and a status code always maintains at 220. The method has the advantages that transient white screen, flashing and delaying phenomena cannot occur during loading of the webpage, load of the server is greatly reduced and a user feels smoother.
