JScript Wait function

Question

I have a function written in JScript (Not javascript) I need to suspend until a certain global variable becomes true. The global variable is changed to true when another function is called after an ajax response:

function(req, event, data) {
  globalVariable = true;
 }

When I try to loop until the variable is true:

while (globalVariable!= true) {
}

I go into a busy waiting and the callback function is never called.

Some suggested the use of WScript.wait() but my app doesn't seam to know WScript. SetTimeout() also won't help because it's asynchronic call and won't suspend my original function.

Any other suggestion?

Some more information regarding my question: I want my script to call 2 functions:

waitWhileAjaxIsNotCompleted();
doSomthingElse();

I want the waitWhileAjaxIsNotCompleted() to click a button that submits an ajax request (implemented by A4J) and terminate upon the ajax completion. In order for me to know when does tha ajax completed, I registered a function as a listener that will be awaken when the ajax completes. This function changes a globalVariable value. My waitWhileAjaxIsNotComplete() goes into an infinite loop, waiting for the glovalVariable value to change. When it does change (After the listener has awaken), I can end the function ad continue with the doSomthingElse() function.

This has been an issue for me as well. Doing a while overloads the processor. The only way I've found so far to solve is to use a state machine, call setTimeout and return.

E.g.

var state = 'unfinished';

function mainFunc()
{
 if(state=='unfinished')
 {
   setTimeout('mainFunc()',1000);
   return;
 }
 alert('The function executed')
}
