how to getElementsByName() with context other than document?

Question

I am unable to search for nodes with a specific name with any other context than document.

is there a cross browser way to search getElementsByName() with a context other than document.getElementsByName()?

Answer 1

getElementsByName is a property of the document only, in all browsers. You cannot add it to the element object prototype in all browsers, and even if you could it would be less efficient than the native implementation. You can do whatever filtering you need on the nodelist returned from document.
