If I am using srcElement (or "target" for non-IE models) to return
various properties of an object I have clicked on, can I access for
"label for" value in any way? I'm thinking, for example, of an input
text box like this:
<label for="fred">Username:</label>
<input type="text" name="hello" id="hello1" size="10">
Now, once a function has:
var obj=event.srcElement || event.target;
... at the top, I should be able to access obj.name and get "hello"
etc, but how can I access the label value of "fred"? I did try
obj.label but it didn't work...

One of the problems you have right away, is that the <label> element is
supposed to reference the <input> element properly, and your example is
not doing so.
This would be a proper setup:
<label for="username">Username:</label>
<input type="text" name="username" id="username" size="10">
As you can see, the <label> element’s FOR attribute has a value that is
now identical to the <input> element’s NAME attribute. That way, when
someone clicks on the “Username:†text, their browser knows that they
want to edit or add to the contents of the <input> element whose NAME
attribute has a value of “usernameâ€, and will place the cursor inside
the <input> element’s field automatically. By sharing the same attribute
value, the browser knows that the <label> is linked to the <input>.
Another problem that you have, is that the <label> is not a parent of
the <input> element. As such, you cannot simply reference the parent of
the <input> tag and expect to be able to access the properties of the
<label> element. As such, you will have to walk up the DOM and walk back
down it to the <label> element.
Of course, another really easy way of accessing the <label> element is
to make sure that its FOR attribute is the same as the <input> element’s
NAME and ID attributes (the way it is supposed to be). That way, all you
have to to is get the <input> element’s ID, and you then have the
<label>’s FOR attribute value to filter for.
Without seeing more of your JS, this is the best example I can provide.
I hope this helps.
