Dom Walking For Dummies
Dec 20, 2006
I'm working on a little javascriptlet/greasemonkey script, and I've run
into a challenge that I think can be solved with walking the DOM, but I
feel like I'm kludging my way through and wondering if there might be a
better answer out there.
Here's the problem: I want to insertCell(0) into an existing table, but
the table doesn't have a NAME or ID. I don't have the option of adding
these (it's for Wikipedia) and would like to programatically navigate
my way to the table. The table is inside a FORM element that _does_
have an ID, so it's pretty close to a known entry point. I was
originally planning on using .firstChild a few times in a nested
sequence to work my way down to the table, but it's proving trickier
than I thought it would, hence my question here. Code:

I have a ul I want to access via the DOM that is here:
<div id="options>
<form>
<div>
<div>
<span>Some text</span>
<ul>
...
</ul>
</div>
</div>
</form>
</div>
Each child of #options has text nodes besides the HTML elements. Short of doing
document.getElementById('options').childNodes[1].childNodes[1].childNodes[1].childNodes[3]
or giving the UL an ID, is there any other way I could access that UL? I'm imagining something like an array containing every single child (even grandchildren, etc.) of #options but I don't know if it exists. I know the most sensible thing to do is to give the UL an ID, but I'm curious.

On my page, I have a delete button. But when I press trhe button to delete, I put a standard javascript confirm pop-up window with a "Are you sure..." How do I change the message to read "Are you sure you want to delete the member firstName, LastName"? So that an idiot would know who they are deleting?

After playing with all of the different jQuery interactions, widgets, visual effects, etc. (on the demo pages), I wonder of there is an online website builder that would allow me to easily create web pages with all of these functions, but without having to do any real programming ?

I'm trying to use the plugin at [url] for a form. All the examples I find seem to assume I already have worked with javascripting for 30 years and have 3 PhD's in computer science or they have the code buried in a bunch of other bells and whistles, etc. Can someone show the full code to use to mask a phone # using (999) 999-9999 as the mask assuming the formstarts as follows:
