Your code working fine for me and get back the window object. So issues would be browser compatibility.

//Error:Microsoft JScript runtime error: 'null' is null or not an object
Error is self explanatory. You have tried to open a new window but the paramters were not provided properly.

Here you go and see all about Window.Open[^] method.

function callpopup()
{
var j;
j= showModalDialog("frmPopUp.aspx",window,"status:no;dialogWidth:400px;dialogHeight:350px;unadorned:yes;help:no");
}

Ok. Now you use showModalDialog. Further, the name given to it is a keyword 'window'. + I have no idea why you have posted this comment here!

For showmodalDialog, go here: http://msdn.microsoft.com/en-us/library/ms536759%28v=vs.85%29.aspx

Solution 1

You should give the full URL for this.

var popUrl = "www.domainname.com/frmPopUp.aspx"
