jQuery: Having trouble selecting/acting on parent element

I'm playing around with jQuery and AJAX for the first time, and I seem to have run into a little stumbling block in trying to delete an entry from the database. Or, to be clearer, the item gets deleted from the database successfully, but I can't seem to select the correct element to hide once it's deleted.

Here's what s开发者_运维知识库ome sample code looks like (in this case, I'm simply trying to change the background color for testing purposes: I'll be using fadeOut or equivalent in my production environment -- more explanation follows):

    //When link with class .deleter is clicked, get the parent element's id (which is also that element's id in the database)
    $('.deleter').click(function() {
        var recordToDelete = $(this).closest('ul').attr('id');

    //Send the id to the PHP script, which returns 1 if successful and 0 if not
        $.post("databasefuncs.php?func=delete", { postedMessage : recordToDelete },
            function(result){
                if(result == 1) {
                    //Change the background color of the parent UL to red if successful
                    $(this).closest('ul').css('background-color', 'red');
                } else {
                    //Change the background color of the parent UL to blue if successful
                    $(this).closest('ul').css('background-color', 'blue');
                }

            });
    });

To clarify what it looks like on the front-end, my ULs are set to display: table-row, my LIs are set to display: table-cell, and I have a DIV that contains them all and is set to display: table. Essentially, I have a UL per record and an LI per column in each record.

Thanks!

You have different context inside AJAX callback. So, $(this) points to another object. I suggest you should use closure - variable "item" in following example:

//When link with class .deleter is clicked, get the parent element's id (which is also that element's id in the database)
$('.deleter').click(function() {
    var item = $(this).closest('ul');
    var recordToDelete = item.attr('id');

//Send the id to the PHP script, which returns 1 if successful and 0 if not
    $.post("databasefuncs.php?func=delete", { postedMessage : recordToDelete },
        function(result){
            if(result == 1) {
                //Change the background color of the parent UL to red if successful
                item.css('background-color', 'red');
            } else {
                //Change the background color of the parent UL to blue if successful
                item.css('background-color', 'blue');
            }

        });
});
