aren't you the same person that said you like to use coldfusion's <cfform>
and <cfinput> tags?  why not flex your geek muscles there and resist the
urge to use those cf_newbie tags?

;p

j/k.  couldn't resist.

<tip type="JavaScript" author=".jeff">

Passing an object reference to a form element that shares its name with
other form elements on the page is likely going to not yield the results
you're looking for:

function toggleChecked(oElement)
{
  alert(oElement.length);
  // you'd think this would return the number of elements
  // that share this element's name.
}

<input type="checkbox" name="archive" onclick="toggleChecked(this)"
value="0" />
<input type="checkbox" name="archive" value="1" />

clicking the first checkbox results in an alert() dialog that contains the
string "undefined".  instead, you'll have to perform alittle bit of dom 0
gymnastics to get what you're looking for.

function toggleChecked(oElement)
{
  var oForm = oElement.form;
  var oElement = oForm.elements[oElement.name];
  alert(oElement.length);
}

clicking the first checkbox will now result in an alert() dialog that
contains the number 2, what you'd expect.
