JavaScript FAQ Knowledge Base

Very worth reading

I have been using the JavaScript FAQ Knowledge Base quite consistently over the past few days. It has been EXTREMEMLY helful. Since this site has been so helpful to me, I just wanted to point out a possible solution to Q272. I noticed that you solved the problem by depending on frames. However, this solution only works provided the hidden frame remains when URLs change. Another possible solution that will work all the time (it took me much time to figure this out) is as follows:

function MyOpen(url, name, features)
var aWindow = open("", name, features);

if( aWindow.location.href == "about:blank" )
aWindow.location.replace( url );

When you pass the open function a "" for the url, it does not change the url of the existing window (if indeed it does exist... otherwise it creates one with a href of "about:blank"). This works just as good as checking to see if the window exists.
