jQuery UI Dialog Code Help

Okay, don't laugh, but my friend gave me a fix to a jQuery UI code before I asked for another fix here, and now I have no idea how to combine the two. I'm a total n00b so please help me out here. I tried, but keep getting a syntax error?

I need to merge this (I think it goes right after title):

beforeClose: function(){   $(this).remove();   }

Into this:

function openDialog(url) {
    $("<div class='popupDialog'>Loading...</div>")
        .dialog({
            autoOpen: false,
            closeOnEscape: true,
            width: '900',
            height: 'auto',
            modal: true,
            title: 'Bonus Features'
        }).bind('dialogclose', function() {
            jdialog.dialog('destroy');
        }).load(url, function() {
            $(this).dialog("option", "position", ['center', 'center'] ).bind('dialogopen', function() {

                });
                $(this).dialog("open");
        });
}

$(window).resize(function() {
    $(".ui-dialog-content").dialog("option", "position", ['center', 'center']);
});

Can anyone please help? Thanks.

function openDialog(url) {
    $("<div class='popupDialog'>Loading...</div>")
        .dialog({
            autoOpen: false,

            width: '900',
            height: 'auto',
            modal: true,
            title: 'Bonus Features', //don't forget the comma
            beforeClose: function(){   $(this).remove();   } //placed here
        }).bind('dialogclose', function() {
            jdialog.dialog('destroy');
        }).load(url, function() {
            $(this).dialog("option", "position", ['center', 'center'] ).bind('dialogopen', function() {
                    adjustJQueryDialogOverlay();
