Let me start out by saying that I’m not a JavaScript developer so this question may be rather basic.
When simulating IE’s nonstandard all property I’m using getElementsByTagName('*'), is there a significant performance difference between both methods?
Essentially there should be no noticeable performance hit, and the use of
document.allis unacceptable anyway.There is however a question as to why you would be interested in collecting a set of every element anyway? I can’t think of a single use case for that off-hand that couldn’t be handled better another way.
