in a group of check boxes only allow one to be selected at a time

Question

I want a group of check boxes on a page, when you select a check box I want to clear any other check boxes of checks and just check the one you just clicked on. I have a fiddle that I thought should work, but it never checks the one you clicked on. I don't want to use radio buttons as "no selection" is valid as well

$("#mytable input").change(function(){
$("#mytable input").attr('checked',false);
    $(this).attr('checked',true);
})

jsfiddle

Answer 1

You should rather use radio button with same name. using checkboxes, you need to use:

$("#mytable input").change(function() {
 $("#mytable input").not(this).prop('checked', false);  
});
