Disable/Enable checkboxes using jQuery and special cases

Hi all,

I have this code working well (thanks to leakim):

$.disableFilter = function(queryString)
{
	var url = "getTags.php" + queryString;
	$.get(url, function(filterdata) {
		
		var arr = filterdata.split(",");
		$(":checkbox", "#filter_column").each(function() {
			if( $.inArray($(this).attr("id"), arr) == -1 ) {
				$(this).attr("disabled", true);
			}
			else {
				$(this).attr("disabled", false);
			}
		})

	});
}

Select allOpen in new window

This ajax call returns a set of values after sending a set of values via queryString variable.

Now, I have a load of checkboxes:

<input type="checkbox" onClick="ajaxFunction();" name="filter_option[]" value="25-436 />
<input type="checkbox" onClick="ajaxFunction();" name="filter_option[]" value="25-437 />
<input type="checkbox" onClick="ajaxFunction();" name="filter_option[]" value="25-438 />
<input type="checkbox" onClick="ajaxFunction();" name="filter_option[]" value="26-449 />
...more...

Select allOpen in new window

The value is split into 2, first part being the group_id and the second being the option_id

The jquery code above is used to disable any checkboxes that are NOT in the returned string from the AJAX call.

I need to amend this code based on value as opposed to id and extend it to do the following.

- Depending on the group_id in the first part of the queryString var, only make those appliceable for disabling that do not belong to this group.
- Do not disable any checkboxes already checked

An example of queryString var might be:

filter_options=1-1,1-2,1-5,2-6,2-10,3-15,3-16

([group_id]-[option-id])

Return value is just option_ids which are appliceable for further filtering: 16,17,18,19 etc..

So I need to adjust my code to:

- Extract the group_id from the first value in queryString
- Run trhough the checkboxes and disable those not in the returned value (except those that belong to the first group_id and those that are already selected)

Hope that makes sense, bit hard to explain!

huge thanks
