Ajax post and Web-kit browsers

Ajax post and Web-kit browsers

I posted this problem in the old mailing list, but I thought I’d try here with a larger set of eyes.

My issue seems to concern webkit browsers.  I am sending information from a form with a jQuery click function. I am loading the response from one form that is a DIV called rightContent to the same DIV and passing  the information along.   While in IE and FireFox the data is passed to the DIV rightContent, in Chrome and Safari the data is plotted as a new page, as I can see from looking at the address bar.

The test website is http://www.rouse.ws/furiTest/.  To see the problem click on the Donation option and then click on continue.

Below is the code used for processing the event.

 Any suggestions? 
Thanks! 

[code]

            $("#donateButton").click(function () {

                $('#rightContent').html(ajax_load);

                $.ajax({

                    type: 'POST',

                    url: 'content/creditCardAuthorize.php',

                    data: {

                        amount: $('#amount').val(),

                        description: $('#donation').val()

                    },

                    success: function(html){

                        $('#rightContent').html(html);

                    },

                    dataType: 'html'

                });

            });

[/code]
