How do you get a browser window ID?

The following code can be used to refresh a browser window. What I need to know is how to get the ID of a window.

<script language=""javascript"">theotherwindowid.document.reload();</script>

I could be wrong, but I don't know if you can. There are other ways, like:

Code:

---

var newWin = window.open();
newWin.document.reload(true);

---

or I think:

Code:

---

window.opener.document.reload();

---

Maybe if we could see what you're trying to do in context we could help more.
