thank you.

you can this:

$(':checkbox').change(function() {     var chkvalue=$(this).attr("value");       if($(this).is(':checked'))    {           $(':checkbox[value*="'+chkvalue+'"]').prop('checked', true);       //use selector^= or selector*= per need    }    else    {       $(':checkbox[value*="'+chkvalue+'"]').prop('checked', false);    } });
