How to access parent iframe elements from a child javascript page?

Question

I have 2 pages: Parent and child.

In the parent page I have an iframe whose value I want to fetch in the JavaScript of child page. Is there any way?....Please suggest

Answer 1

Use

parent.getElementById('elementId').value;

to get the element. If you have multiple nested iframes, you can get the root parent by using

top.getElementById('elementId').value;

Either will work in your case.
