How to retrieve an element from another DOM element

[Frinavale]

Is there a method like document.getEle mentByID() which will retrieve an element from another DOM element?

Rephrasing: Say I retrieve a Div element using the getElementID method, is there a method to retrieve an element from within that element?

Yes, getElementsByTa gName() and getElementsByNa me(). These will return an array, so you just need to index them, e.g.

elem.getElementsByTagName("a")[0]

returns the first link element within elem.

Edit: also see Navigating nodes

Thanks acoder

It's actually getElementsByNa me(). Having said that though, it wouldn't work here because it's a method of document only unlike getElementsByTa gName(). You can also use the childNodes property. With some newer browsers, you can also use getElementsByCl assName().

You can use the $find method if developing with the .NET Ajax Framework.
