The problem that IE8 cannot be refreshed every time using ajax is introduced as follows: I recently discovered that using ajax to access the background and ie8 to access, The value can be returned normally for the first time, and the background will not be executed thereafter, and the result of the first access will always be returned.

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

After testing, it was found that ie8 cached the result obtained for the first time, so it would not be submitted to the background the second time.

Add a random number after the ajax request to make each request inconsistent, and ie will not obtain the results from the cache.

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