Update script for disabling checkboxes with jquery

I use this piece of code that was written with jquery 1.4.2 I didn't write it my self obviously and I don't have enough knowledge of jquery to know how to rewrite this for the latest version of jquery so it doesn't break when importing the new jquery library.

$('input[type=checkbox]').change(function(){
    name = $(this).attr('class');
    id = $(this).attr('id');
    checked = $(this).attr('checked');
    $('input[type=checkbox][class='+name+']:not(#'+id+')')
        .attr('disabled',checked)
        .each(function(){
            lid = $(this).attr('id');
            if (checked) {
                $('label[for='+lid+']').addClass('disabled');
            } else {
                $('label[for='+lid+']').removeClass('disabled');
            }
        });

});

This is the original post where I got it from, it includes a jsfiddle link :) Thanks in advance!
