JavaScript: 2 window.opener.location.href statements with alert() in between not functioning - Stack Overflow

I need to make a little JS app to scroll automatically through a list of URLs. I've chosen to have the functionality in a pop-up, for various reasons.

The syntax to change the opening window's URL is:

window.opener.location.href = "";

This works fine with one URL, but if two statements are called, only one is executed. I experimented with an alert statement between two of the above statements, and the alert event made the second statement function properly:

window.opener.location.href = "";
alert("hello world");
window.opener.location.href = "";

Question is: does anyone know how to get the first and second window.opener statements to work, without the intervening alert();? Also, how can I add a pause between the two statements, so that the second executes a couple of seconds after the first?

Thanks so much!

• see if that title works any better (if not change it back :). Hard to describe concisely. – Gordon Gustafson Commented Jun 8, 2010 at 0:44
• "This works fine with one URL, but if two statements are called, only one is executed" Which one? I suspect they're both executed, it's just that you only see the result from one of them. – T.J. Crowder Commented Jun 8, 2010 at 0:50

You need to call setTimeout, like this:

window.opener.location.href = "http://www.example1.";

setTimeout(function() {
    window.opener.location.href = "http://www.example1.";
}, 5000);        //5,000 milliseconds

Is the original location of the opener page also at http://www.example1.? If not, then when the first statement executes and it changes the location of the opener to a different domain, then the window.opener property bees not accessible -- hence the second statement fails.
