jQuery Ui Dialog Buttons, How to add class?

Question

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?<

Answer 1

Use the open event handler:

open: function(event) {
     $('.ui-dialog-buttonpane').find('button:contains("Cancel")').addClass('cancelButton');
 }

Clean, simple, piece of cake!
