Javascript Select/Deselect checkbox

I have a list of checkboxes.  I already have a code that does Select/Deselect all.  Pretty much all that code does is toggle the status.  

What I need is a true Select/Deselect all code.

So when you check the box to Select All, if any boxes are currently checked, it would leave them alone.  Any boxes that aren't checked, it would check them.  

Same for Deselect.  If you uncheck the box, then any boxes that are currently checked would uncheck.  Any boxes that are currently unchecked would remain unchecked.

That code doesn't seem complete or well laid out.  I cannot get it to work.

I have this and it works....but it's individual buttons to select all and deselect all.  I really would rather it just be one checkbox to select all or deselect all.  


<SCRIPT LANGUAGE="JavaScript">
function checkAll(field)
{
for (i = 0; i < field.length; i++)
	field[i].checked = true ;
}
 
function uncheckAll(field)
{
for (i = 0; i < field.length; i++)
	field[i].checked = false ;
}
 
</script>
 
<input type="button" name="CheckAll" value="Select All" onClick="checkAll(document.tstest.bApproved)">&nbsp;
<input type="button" name="UnCheckAll" value="Deselect All" onClick="uncheckAll(document.tstest.bApproved)">

ok glad i could help.  but if you select all on that code, paste it into a blank notepad, and save it as test.html, it will work.  something must have happened when you put the code on your asp page.
