表单响应更改值

Question

我试图让它成为当你提交我的表格时 - 如果你输入名字中的'Martin'，姓氏中的'Neuhard'，并在下拉列表中选择'Binghamton University'，它会改变背景绿色和弹出窗口宾汉姆顿大学的一个小调。如果我使用||，它可以工作但不是当我使用＆amp;＆amp;。

另外我想这样做，如果两个电子邮件字段不一样那么警告（'错误'）

我已经尝试了几个小时，但无法理解。 jsfiddle在

像这样的东西

$(document).ready(function () {
    $('#check-btn').click(function (e) {
        e.preventDefault();
        var $form = $('form');
        var fName = $('#name', $form).val();
        var lName = $('#lname', $form).val();
        var school = $('#dropdown', $form).val();
        if(fName == 'Martin' && lName == 'Neuhard' && school == 'bing'){
            //do something here
            $('#contact').addClass('green');
        }
        else if(fName == 'martin'){
            alert('thats our profs name!')
        }

        //if the 2 emails are not the same
        var email = $('#email', $form).val();
        var repeatEmail = $('#emailCheck', $form).val();
        if(email != repeatEmail){
            alert('Email does not match!');
        }
    });
});
