Jquery表单值确认

Question

有人能告诉我为什么这会出现错误吗？我正在尝试使用类似的代码在我使用jquery mobile构建的Cordova应用程序中的用户身份验证系统，以确保密码和密码确认是相同的。然后将这些数据发送到我服务器上的php文件，然后根据验证，然后php将返回＆＃34; success＆＃34;或＆＃34;失败＆＃34;。因此，我有另一个问题是如何根据从php文件返回的结果我可以改变我对应用程序的看法？如果有人可以建议我这样做的好方法或者我可以学习的教程，那将是很棒的，因为我无法找到这方面的好教程，因为我是这一切的新手。

$(document).on('pagebeforeshow', '#signuppage', function () {
$(document).on('click', '#signupbutton', function () {
    if ($('#confirmpassword').val() === $('#password').val()) {
        $.ajax({
            url: 'http://localhost/appAuth/profiling.php',
            data: {
                action: 'signup',
                formData: $('#signupform').serialize()
            },
            type:'post',
            async: true,
            dataType: 'json',
            beforeSend: function () {
                //this is the callback function will trigger before data is sent
                $.mobile.showPageLoadingMsg(true);
            },
            complete: function () {
                //this is the callback functino will trigger on data sent/received complete
                $.mobile.hidePageLoadingMsg();
            },
            success: function (result) {
                resultObject.formSubmitionResult = result;
                $mobile.changePage("#collections");
            },
            error: function (request, error) {
                //this is the callback function will trigger on unsuccessful action
                alert('Network error has occured please try again!');
            }
        });
    }
    else
    {
        alert('Please make sure the two passwords match!');
    }
    return false; //cancel original event to prevent form submitting
});
});

以下是请求的HTML：
