am trying some code but that is not working

my Javacsript Code

<script type="text/javascript">
    $('input.chk').on('change', function () {
        $('input.chk').not(this).prop('checked', false);
    });
</script>

Please Give the any suggestion. Thanks

Answer 1

Your selector is wrong. None of your elements have a class of chk . It should be chkClass :

 $('input.chkClass').on('change', function () { $('input.chkClass').not(this).prop('checked', false); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <input type="checkbox" class="chkClass"> <input type="checkbox" class="chkClass"> <input type="checkbox" class="chkClass">
