DomHelper offers similar functionality to that provided by static utility methods within goog.dom. The difference is that a DomHelper instance can be bound to a document object corresponding to a different window, such as an IFrame, or the parent frame. This basically allows UI controls to conduct their DOM manipulations within the confines of the correct window, even if the actual objects live in another.

Assuming you are referring to goog.dom.DomHelper - it looks like it provides an efficient, cross-browser solution to DOM manipulation.

thanks. there's dom_helper optional parameter everywhere, what is it for? – Evgeny Feb 18 '10 at 22:55
turns out it's a reference to an alternative dom object that javascript has access to - like the one from another frame – Evgeny Feb 19 '10 at 05:02
it's not necessary if you have a single frameless page – Evgeny Feb 19 '10 at 05:02
