jQuery Ajax call - Set variable value on success [duplicate]

javascript jquery ajax asp.net web-services

Since you need this behavior in the unload event, you will have to make a synchronous call instead. However it may freeze the browser window/tab dependent on how long the call will take, but because you're effectively trying to prevent the user from closing the window...

Add async: false to your JSON to make a synchronous call.


An example of jquery page:

var html = $.ajax({
  url: "some.php",
  async: false
 }).responseText;
