Jquery .dialog disable submit button after click

[admin]

I am customizing a wordpress theme. When the user clicks the submit button it should be disabled.

I was not able to figure out how to do it.
Here is the code. Could someone please tell me how to do this.

jQuery('.modal-content').dialog({
                autoOpen: false, 
                title: 'Confirm your Res', 
                resizable: false,
                height: 175,
                width: 300, 
                modal: true, 
                buttons: {
                    Submit: function() {                                    

                        jQuery('form[name="booking-form"]').get(0).submit();
                    }, 
                    Cancel: function() {
                        jQuery(this).dialog("close");

                    }
                }
            });
