Answer 2

It seems to me removeProp is not working properly in Chrome : jsfiddle

        $('#badBut1').click(function () {
        checkit('Before');
        if( $('#chk').prop('checked') )
        {
          $('#chk').removeProp('checked');
        }else{
            $('#chk').prop('checked', true);
        }
        checkit('After');
    });
    $('#But1').click(function () {
        checkit('Before');
        if( $('#chk').prop('checked') )
        {
          $('#chk').removeClass('checked').prop('checked',false);
        }else{
            $('#chk').addClass('checked').prop('checked', true);
        }
        checkit('After');
    });

    $('#But2').click(function () {
        var chk1 = $('#chk').is(':checked');
        console.log("Value : " + chk1);
    });

    $('#chk').on( 'change',function () {
        checkit('Result');
    });
    function checkit(moment) {
        var chk1 = $('#chk').is(':checked');
        console.log(moment+", value = " + chk1);
    };

Answer 3

Use :checkbox selector:

$(':checkbox').change(function() {

        // do stuff here. It will fire on any checkbox change

});

Answer 4

Hope, this would be of some help.

$('input[type=checkbox]').change(function () {
    if ($(this).prop("checked")) {
        //do the stuff that you would do when 'checked'

        return;
    }
    //Here do the stuff you want to do when 'unchecked'
});

Answer 5

get radio value by name

  $('input').on('className', function(event){
        console.log($(this).attr('name'));
        if($(this).attr('name') == "worker")
            {
                resetAll();                 
            }
    });

Answer 6

You can use Id of the field as well

$('#checkbox1').change(function() {
   if($(this).is(":checked")) {
      //'checked' event code
      return;
   }
   //'unchecked' event code
});
