I want to delete an entry from a user list and the rows classes

  • 0

I want to delete an entry from a user list and the rows classes should be rearrange, so that no two consecutive rows have the same class. How can I reorder the rows classes after deleting an item from the list? For example: If I delete the item ‘five’, the elements ‘four’ and ‘six’ have the same rows classes.

    Try changing your JS to something like this:

    <script type="text/javascript">

$(document).ready(function(){

    function reassign()
    {
    var i =0;
    $.each($('ul#users > li'), function() {
            $(this).attr('class', 'col' + (i % 2));
            i++;
    });
    }

    // hover class
    var clshover = "col2";

    // confirm message
    var msgconfirm = "You really want to delete this entry?";

    // Hover effect
    $('ul#users > [class^=col]').hover(
        function () {
            $(this).addClass(clshover);
        },
        function () {
            $(this).removeClass(clshover);
        }
    );

    // Delete a defined entry
    $('ul#users > li > a.delete').click(function (){
        if (confirm(msgconfirm)) {
            $(this).parents('li').remove();
            reassign();
        }
    });

});

</script>
