Or use jQuery and do
$('#myDiv').find('#elemInMyDiv');
Or, if elemInMyDiv is a direct child of myDiv:
$('#myDiv > #elemInMyDiv');

Subject: Re: [WEB400] javascript - use getElementById to get element within a div
The following should work fine:
document.getElementById('elemInMyDiv');
If you this is an issue because you are creating elements with duplicate ID
names, it is allowed but considered bad practice. I would recommend adding
a counter of something similar so that all the "id" attributes are unique.
When you want to group elements together using an attribute, use "class" or
"name" - keep ID unique and your life will be a lot easier.
That all said, if you want to dig out a specific element within a DIV, it
can be done but it is a little extra work. You would have to loop through
all the elements until you find the one with a matching ID. Having a unique
ID for each element is usually a much simpler way of handling things.
