jquery ajax Async Parameters cause Firefox browser splash screen

Async default is True, which is asynchronous, $. After Ajax executes, it will continue to follow the footsteps of Ajax until the server side returns data, triggering $. The success method in Ajax. Two threads are executed at this time.

My flash-screen situation is:

The code is as follows	Copy Code
$.ajax ({ Type: "Post", URL: "index.php", Data: {}, Async:false, Beforesend:function () {}, Success:function (data) { //... }, Complete:function () {} });

Here, my async is set to False, the original intention is to return the data and then execute $. Ajax behind the script, did not think this place has led to a splash screen in Firefox browser. (Firefox 11.0), the scroll bar down to the bottom of the trigger Ajax situation. Splash screen

Finally, the Async:false comment out, that is, async for ture case, successfully resolved the Firefox browser scroll down to the bottom of the trigger Ajax flash screen problem.
