Question

I have a DOM object obj of the type <input>, and want to get is parent node, but obj.parentNode gives back the same obj.Is this a specification of <input> objects? If so, what other kinds of DOM objects behave irregularly (returns anything other than its parent in an intuitive sense) like this?

Edit I must have done something wrong. sorry.

Answer 1

input behaves no differently than any other element on a page, and returning its parentNode() should not return the input itself. Try it out:

<p><input type='text' id='my_id' onfocus="alert(this.parentNode.tagName)" /></p>

This will alert “P”.

I’m guessing that you’re not correctly testing for the parentnode.
