I have a jquery variable that is storing a comma separated list of id names. I need help writing something in jquery that separates that variable and uses those values to populate a forms checkbox values when the page loads.

so my jquery variable is $storedFormValues that is a comma separated list of values "checkbox1, checkbox, etc."

and my form

```
<form name="formname" id="formid">
<input type='checkbox' class='catcheck' id='checkbox1' value='checkbox1' name='catselect' />Checkbox 1
<input type='checkbox' class='catcheck' id='checkbox2' value='checkbox2' name='catselect' />Checkbox 2
<input type="submit" name="submit" value="Submit" />
</form>

```

Any help would be greatly appreciated!
