How to get iframe scroll position in IE using Java Script?

问题

scrollPosition = window.frames[id].document.body.scrollTop;

The above code doesn't work correctly. Please tell me how to correct it.

回答1:

To get scrollTop in a crossbrowser way jQuery does this:

function GetScrollTop()
{
   var doc = document.documentElement
   var body = document.body;
   return ((doc && doc.scrollTop) || (body && body.scrollTop || 0)) - (doc.clientTop || 0);
}

I personally use simply this:

return document.documentElement.scrollTop || document.body.scrollTop

If the frame's document is located on a different domain, you will not be able to access most properties and objects on it due to the same origin policy.

Well, I think that what you're looking for is easy obtainable if you're using jQuery. So that might be worth looking into?
