Hi,
Given an <input/> field, I'm trying to determine the <form/> in which it's
contained. I've
written
this recursive function:
/** Returns null if there is no form **/
findForm : function(node) {
// |node| is an <input type="text"/> field
if (node.nodeName == "FORM")
return node;
return node.parentNode ? this.findFormName(node.parentNode) : null;
},
This works for all pages I've tried except this one:
http://passwordmaker.org/proto/eraseme.html.
In that case, the function returns null. I don't understand why it's not
working. Anyone care
to
take a look?
Doesn't just node.parentNode work for this?
No, because the DOM might look like this:
<form><div><input/></div></form>
in which case, node.parentNode = <div/>
But the question is now moot since I've learned about the form attribute of
input elements. Oops,
I didn't test if that works in Mozilla... just Firefox.
Right, never answer before waking up HJ (I'm working remote again).
