Checking (and unchecking) all Checkboxes with JQuery

If you wish to check (tick) or uncheck (untick) all checkboxes with JQuery use the find, each and attr functions. This will loop through every checkbox element and set the attribute you want.

Example of checking every checkbox:

1
2
3

$("#div").find("input[type='checkbox']").each(function(){
                $(this).attr('checked', true);
         });
