停止javascript执行直到jquery JSON响应

Question

I am calling a third party webservice using getJSON callback. The function does not have a success handler attached to the function and since it is third party, I cannot edit the code also. By the time I receive the response, some of the javascript function in the page already executes.

Is there any way I can delay the execution of the Javascript function till I receive the response data from web service except setTimeout method.

Answer 1

Description

You can use jQuery's .ajaxStart() and .ajaxComplete() events to get noticed if your ajax call is running. You can create a bool variable, something like isAjaxRunning and put this around the other javascript. So if isAjaxRunning is true, dont execute other javascript.

More Information

• jQuery.ajaxStart()
• jQuery.ajaxComplete()

Answer 2

if you have access to the code you can make it synchonize by adding the attribute

async : false - then it won't be a asynchronous call like the normal ajax .

If you can post the sample code - that will give a clear picture.
