How Do I Loop Through Different Iframes?

I am stuck on how to load one iframe and have the next one queuing to be displayed. How would I write a script that loops through different iframes after time?

Solution 1:

for (var i=0;i<self.frames.length;i++) {
    var buttons = self.frames[i].document.getElementsByTagName("button");
    // Do stuff with buttons
}

Hope it will do your work
