Quirks to strict mode in IE

Are there Javascript implications?

[Robin_reala]

We're redoing an older web app of ours and want (for styling purposes) to move from quirks mode to strict. I can think of a couple of changes needed to be made to the JS straight away - 'px' on units, '#' on colours - but is there anything more fundamental that might be an issue?

Thanks!

Certain properties move up in the DOM hierarchy.

scrollTop

is one that comes to mind: in strict mode, it no longer belongs to

body

but becomes a property of the

documentElement

element. Try this to see it in action in different modes:

alert(document.body.scrollTop); 
alert(document.documentElement.scrollTop); 

(make sure there is a scrollbar...)

Edit: this also applies to

scrollLeft, offsetWidth, offsetHeight

and probably a few more.

Ah yeah, I remember seeing that on Quirksmode. Thanks!
