How to remove the unchecked item from Array using jquery

Question

I have this code to put it in array when user checks the check box.. but when user unchecks the check box how do I need to remove from the Array?

 $(function () {
   var listval = [];
        $('input[name="checkedRecords"]').bind('click', function () {
            if ($(this).is(':checked')) {
                listval.push($(this).val());
            }
            else {
                //How to remove the Unchecked item from array..
            }
        });
    });

Thanks in advance.

Why not generate the array whenever you need it?

If you have an array

var mylist = ['a','b','c','d'];

To remove the value 'b':

if ((index = mylist.indexOf('b')) !== -1)
    mylist.splice(index, 1);

Results in:

mylist == ['a','c','d'];

For your application:

 $(function () {
   var listval = [];
        $('input[name="checkedRecords"]').bind('click', function () {
            if ($(this).is(':checked')) {
                listval.push($(this).val());
            }
            else {
                if ((index = listval.indexOf($(this).val())) !== -1) {
                    listval.splice(index, 1);
                }
            }
        });
    });

I am getting a page error saying Object does not support this property or method.

Are you sure that error is coming from this code? Do a console.log($(this)) at the top of the function and see what is triggering the click

I am sure error is coming from this line of code if ((index = listval.indexOf($(this).val())) !== -1)

You could use $.inArray instead.
