How to get unchecked checkbox value in jquery

Question

I have created bellow script to select/deselect multiple check-box and store selected check-box value in hidden filed. Now I need your small help to complete this things. When user deselect any check-box I want that deselected check-box value to perform some task.

My JS Code:

jQuery.noConflict();
function toggle_chkbox(source,group,lbl) {
    checkboxes = document.getElementsByName(group);

    for(var i=0;i<checkboxes.length;i++)
    {
        var chkid = '#'+lbl+i;

        checkboxes[i].checked = source.checked;

        if(jQuery(chkid).hasClass('c_on') && checkboxes[i].checked == false  )
        {
            jQuery(chkid).removeClass('c_on').addClass('c_off');
        }
        else if(jQuery(chkid).hasClass('c_off') && checkboxes[i].checked == true  )
        {
            jQuery(chkid).removeClass('c_off').addClass('c_on');
        }
    }
    updateTextArea();       
}

function updateTextArea() {   
    var allVals = [];
    jQuery('.taglist :checked').each(function(i) {
        allVals.push((i!=0?"":"")+ jQuery(this).val());
     });
        jQuery('#textValue').val(allVals).attr('rows', allVals.length);
     }
     jQuery(function() {
        jQuery('.taglist input').click(updateTextArea);
});

My Live Code:

Sorry for not creating jsFiddle or jsbin as I am getting error on that. :(

Any ideas or suggestions? Thanks.

$(".taglist :not(:checked)").each(function() {
  alert($(this).val());
}

Like this you can get all the unchecked values and u can store it in an array or perform any operations on it as u want...Hope it helps you..

you can bind a onChange function to the checkboxes and perform needed actions there:

$(<selector>).on("change",function(){
    //doThings 
});

like in your sample code:

for(var i=0;i<checkboxes.length;i++){
    var chkid = '#'+lbl+i;
    $(chkid).on("change",function(){
        //do things
    });
}

i don't really know what you mean by that....just checking if(!checkboxes[i].checked) does not work for you?
