Check/Uncheck All

I'd like the ability to have a checkbox that will check all elements with a certain name when selected, and to have another checkbox that will do the same with another set of elements.

I had found the following code, and it worked:

function toggleChecked(oElement)
{
oForm = oElement.form;
oElement = oForm.elements[oElement.name];
if(oElement.length)
{
bChecked = oElement[0].checked;
for(i = 1; i < oElement.length; i++)
oElement[i].checked = bChecked;
}
}

function toggleController(oElement)
{
oForm=oElement.form;oElement=oForm.elements[oElement.name];
if(oElement.length)
{
bChecked=true;nChecked=0;for(i=1;i<oElement.length;i++)
if(oElement[i].checked)
nChecked++;
if(nChecked<oElement.length-1)
bChecked=false;
oElement[0].checked=bChecked;
}
}
I was able to the use the following HTML for my check/uncheck checkboxes:

<input type="checkbox" name="addsuggestedjokes[]" onclick="toggleChecked(this)" />
<input type="checkbox" name="removesuggestedjokes[]" onclick="toggleChecked(this)" />

And the following for my other checkboxes:

<input type="checkbox" name="addsuggestedjoke[]" value="<?php print $jokeid ?>" onclick="toggleController(this)" />
<input type="checkbox" name="removesuggestedjoke[]" value="<?php print $jokeid ?>" onclick="toggleController(this)" />

However, this presented a problem because I do not want my check/uncheck checkboxes to be part of my addsuggestedjoke[] or removesuggestedjoke[] arrays!

I tried to change everything as follows, but it doesn't work:


Changed toggleChecked:

function toggleChecked(oElement, elementName)
{
oForm = oElement.form;
oElement = oForm.elements[elementName];
if(oElement.length)
{
bChecked = oElement[0].checked;
for(i = 1; i < oElement.length; i++)
oElement[i].checked = bChecked;
}
}
Changed check/uncheck HTML:

<input type="checkbox" name="addallsuggestedjokes" onclick="toggleChecked(this, 'addsuggestedjoke[]')" />
<input type="checkbox" name="removeallsuggestedjokes" onclick="toggleChecked(this, 'removesuggestedjoke[]')" />

How can I make this work?
