Question

I have something like this in a JavaScript control, how does one subscribe to this event?

if(typeof(pnlDialog.onclose) == 'function')
     pnlDialog.onclose();

I thought it was something like this, but haven’t been successful.

var mycontrol = document.getElementById('myDialog');
mycontrol.attachEvent('onclose', function() 
{
         alert('closed');
});

Looks like it’s not using events at all, its just using a late bound function. Therefore use this:

var mycontrol = document.getElementById('myDialog');
mycontrol.onclose = function(){
  alert("Closed");
}
