Introduction to AJAX

AJAX = Asynchronous JavaScript and XML (asynchronous JavaScript and XML).

AJAX is not a new programming language, but a new way to use existing standards.

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

The problems that cannot be refreshed every time IE8 access with ajax are described as follows:

Recently, it has been found that using ajax to access the background and ie8 access can return a normal value for the first time, and then the background will not be executed all the time, always returning the result of the first visit.

There is no problem with ie9,ie10, chrome, and other browsers.

After testing, it is found that ie8 caches the results obtained the first time, so the second time will not be submitted to the background.

Add a random number to ajax's request so that each request is inconsistent and ie will not get the result from the cache.

For example, add ".... & random=" + Math.random () after the ajax request; so that each request is inconsistent and ie will not fetch the result from the cache.
