AJAX is not a new programming language, but a new way of using existing standards.

AJAX is the art of exchanging data with the server and updating parts of the Web page without reloading the entire page.

IE8 with Ajax access can not be refreshed each time the issue is described as follows:

Recently found that using AJAX to access the background, with IE8 access, the first time you can return the value of the normal, the following will not perform the background, always return the results of the first visit.

There is no problem with IE9,IE10, Chrome, and so on browsers.

After testing, it is found that the IE8 cache the results of the first fetch, so the second time will not be submitted to the background.

After the AJAX request plus a random number, so that each request is inconsistent, IE will not get the results from the cache.

After the AJAX request, add "... &random=" +math.random (); So each time the request is inconsistent, IE will not take the result from the cache.
