This article is about how Ajax implements asynchronous submission of classes and supports cross-domain. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The code is as follows:

Asynchronous request class

Creation time: 2009.2

Modify the record:

2009.4.27Mel-add URL detection, if it is "http://xxxx.xxx.xx.xx/.." This format can be obtained using the "/ getUrl.aspx" provided by the system.

To solve cross-domain problems.

There are two main parameters of getUrl.aspx: 1. The url value is the target URL (you can have parameters in URL)-- must be; 2. The method value is the method used by the agent (optional)

If method is empty, the POST method is used by default; if the FORM parameter is empty (that is, request.content-length=0), it is automatically set to the GET method

(note: getUrl.aspx redesigned on April 27, 2009, adding a Cookie agent on the basis of the original completed agent.)
