How to get url of newly created window or tab on button clic

Hi,

Try this :

 var PopupUrl = "";
    PopupUrl = 'http://www.google.com/images';
    if(PopupUrl != "")
    {
        var doc=window.showModalDialog(PopupUrl, window,"scrollbars,resizable,width=500,height=400","");
        alert(window.name);
    }

I have used :

var winX = window.open('http://www.google.com/images', "newStuff", "height=500px,width=500px");
var x = winX.location.href;
alert(x);
The alert is about:blank

Open new window like this :

var winX=window.open("newurl.htm","","width=100,height=50");

Then fetch child window url :

var x=winX.location.href;
alert(x);
