matteradmin16PV0评论

I want to get checkbox value using jQuery when to uncheck the checked checkbox and show that unchecked value in the popup. I've tried below code but it not work

$("#countries input:checkbox:not(:checked)").click(function(){
    var val = $(this).val();
    alert('uncheckd' + val);
}); 

Is it possible to get unchecked value in this way?

Reset to default 61

Your selector will only attach event to element which are selected in the beginning. You need to determine check unchecked state when value is changed:

$("#countries input:checkbox").change(function() {
    var ischecked= $(this).is(':checked');
    if(!ischecked)
    alert('uncheckd ' + $(this).val());
}); 

Working Demo

You should check the condition on click or change. I hope that my example will help you.

    $("input:checkbox.country").click(function() {
        if(!$(this).is(":checked"))
        alert('you are unchecked ' + $(this).val());
    }); 
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

    <input class="country" type="checkbox" name="country1" value="India" /> India </br>
    <input class="country" type="checkbox" name="country1" value="Russia" /> Russia <br>
    <input class="country" type="checkbox" name="country1" value="USA" /> USA <br>
    <input class="country" type="checkbox" name="country1" value="UK" /> UK

 $("#countries input:checkbox").on('change',function()
 {
   if(!$(this).is(':checked'))
      alert('uncheckd ' + $(this).val());
 });
