Question

I have the following code that pushes check-box values to an array. I want to be able to remove the values from array if check-boxes are unchecked. Can anyone tell me how to do this.

var arr_sort = new Array();

$(".sort").change(function(){

        $.each($("input[name='sort']:checked"), function() {
           arr_sort.push($(this).val());
        });

    });

Notes:

• Use a key/value system. This way you can know which array item to set or unset. This probably means giving your checkboxes names.
• Don’t loop over the array each time every time something changes. That’s bad design and could lead to bad performance. I restructured the HTML.
