I'm assuming that what you want is to have a single check-box that allows
the user to select all in that group.
If so, the easiest way to do that would be to wrap the group up inside a
block level element. You can then retrieve the block level object and loop
over it's children checking all elments that are checkboxes.
Something like this:
<script>
function updateBoxes(src) {
fieldset = src.nextSibling.nextSibling;
for (i=0;i<fieldset.childNodes.length;i++) {
thisNode = fieldset.childNodes[i];
if (thisNode.tagName == 'INPUT'
&& thisNode.getAttribute('type').toLowerCase() ==
'checkbox') {
thisNode.checked = src.checked;
}
}
}
</script>
<input type="checkbox" onClick="updateBoxes(this)"> Select All
<fieldset>
<input type="checkbox" name="foo"> Foo
<input type="checkbox" name="foobar"> Bar
<input type="checkbox" name="foo"> Foo
</fieldset>
