jQuery Ui Dialog Buttons, How to add class?

I found this answer on another thread..

How to add multiple buttons in Jquery UI dialog box?

Using this syntax, how do you add class to a particular button?

 $("#mydialog").dialog({
      buttons: {
        'Confirm': function() {
           //do something
           $(this).dialog('close');
        },
        'Cancel': function() {
           $(this).dialog('close');
        }
      }
    });

It doesn't look like there's a great way to do this via the API, however you could add the classes in an event handler for create:

$("#dialog").dialog({
    buttons: {
        'Confirm': function() {
            //do something
            $(this).dialog('close');
        },
        'Cancel': function() {
            $(this).dialog('close');
        }
    },
    create:function () {
        $(this).closest(".ui-dialog")
            .find(".ui-button:first") // the first button
            .addClass("custom");
    }
});

If you wanted the second button, you could use:

$(this).closest(".ui-dialog").find(".ui-button").eq(1).addClass("custom") // The second button

The key is the $(this).closest(".ui-dialog").find(".ui-button"), which will select the buttons in your dialog. After that, you could apply any selector you want (including :contains(...) which might be useful if you want to select a button based on its text instead of its order).

Here's an example: http://jsfiddle.net/jjdtG/

Also note that the CSS selector for the style(s) you want to apply has to be more specific than jQueryUI's built-in selectors in order for the styling to be applied.
