Question

How can I refer to a nested div by id when it has the same id as a div nested in a similarly named div

eg

<div id='obj1'>     <div id='Meta'>         <meta></meta>     </div> </div>  <div id='obj2'>     <div id='Meta'>         <meta></meta>     </div> </div> 

I want to get the innerHTML of meta

document.getElementById('obj1').getElementById('Meta').getElementsByTagName('meta') 

doesn’t work

Answer 1

IDs should only be used when there is one of that item on the page, be it a SPAN, DIV or whatever. CLASS is what you should use for when you may have a repeating element.

Code there doesn’t work because you’re referring to an element by unique ID, but have more than one on the page.
