Javascript new window - activate old if already popped up

Hi,

I'm maybe onto nothing here.

I have button that lets user popup a unit calculator, see javascript below. If the user clicks to open it again, instead of opening a another new window, I'd like to activate existing popup...can I do this ?

Thanks in advance
function openConvertor() {
        var load = window.open('../UI/UnitConvertor.aspx','','scrollbars=no,menubar=no,height=450,width=400,resizable=yes,toolbar=no,location=no,status=no');
 
     }

Open in new window

Just name the window that you are opening in JavaScript.  I believe it is the second parameter you have as blank now.  What this will do is open the JavaScript in the same named window, so as long as it is still open it will use it.
var load = window.open('../UI/UnitConvertor.aspx','MyWIN','scrollbars=no,menubar=no,height=450,width=400,resizable=yes,toolbar=no,location=no,status=no');

Open in new window

you can just add a check like this:

if (load.closed){
  var  load = window.open('../UI/UnitConvertor.aspx','','scrollbars=no,menubar=no,height=450,width=400,resizable=yes,toolbar=no,location=no,status=no');

}else{
   load.focus();
}

Sorry, need more coffee.  Brad2575, nice catch.  I was thinking needed to open in same window, but the question clearly is asking to reactivate existing. :)

hi, thanks for helpers this is the kind of idea

I have tried code from brad2575 but get "closed" is null or not an object.

There is a page called UnitConvertor.aspx with link, user clicks on that to get popup.
they may navigate away from UnitConvertor.aspx, go to another page, and back and click on the popup again

Thanks for further help

Hi,

The idea is the same but you need a little to make it works.

Put this in your code and test it out

Hope this helps

var newwindow = '';
 
function openConvertor() {
	if (!newwindow.closed && newwindow.location) {
		newwindow.location.href = '../UI/UnitConvertor.aspx';
	}
	else {
		newwindow=window.open('../UI/UnitConvertor.aspx', 'myPopup',  'scrollbars=no,menubar=no,height=450,width=400,resizable=yes,toolbar=no,location=no,status=no');
		if (!newwindow.opener) newwindow.opener = self;
	}
	if (window.focus) {newwindow.focus()}
	return false;
}

Open in new window
