my javascript hangs the browser (make it unresponsive)

ok. i see. thanks.

so. i need to change my code to make it asynchronous.

But i have one such request in loop how can i make it asynchronous.

eg

function tmp()
{
    do
            {
                  tmp = getParentName(idarr[idx-1]);
                  if(tmp === false)
                        break;

                  idarr[idx] = tmp;
                  idx++;
            //      alert(idarr);
            }while(1);
}

getParentName does some SOAP request. I can add an extra parameter for a callback routine but how to implement loop logic.

Thanks

well, you would need to make getParentName function asynchronous.
It seems, it waits until the soap request is finished - and inside this function loop causes browser to hang.

SOAP requests should be simple enough not to make several calls to request for data.
You might try to refactor your code, so only one SOAP call is required - which would return an array you need, not to make call for each item.

If you still need to implement loop asynchronously without refactoring the webservice, then:

implement a function, that starts precalculation (in pseudocode):

var idarr= new Array();
var idx;
function PerformCalculation()
{
  // todo: initialize your array
   StartRequest(myCallback); //you need to make sure everything is set up (SOAP Header and so on)
  // it should set asynchronous callback on result to myCallback
}
function myCallback(result)
{
         if(result == false){
            CalculationFinished(idarr);
        } else {
           idarr[idx] = tmp;
           idx++;
           StartRequest(myCallback);
        }
}

function CalculationFinished(arr)
{
   // do whatever you need with the result :)
}

StartCallback should return immedietaly after setting asynchronous callback.

thanks VovinE for your help.
