我写了以下联系表单验证脚本.如何验证电子邮件字段？

<style type="text/css">
    div.contactForm { width:370px; margin:0 auto; }
    form.contactUs label { display:block; }
    form.contactUs input { margin-bottom:10px; }
    input.submit { margin-top:10px; }
    input.error { background:#FF9B9B; border:1px solid red; }
    div.errorMessage { color:#f00; padding:0 0 20px; }
</style>

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>

<script type="text/javascript">
    $(document).ready(function() {
        $('.errorMessage').hide();
        $('.submit').click(function() {

            var name = $('input.name').val();
            var email = $('input.email').val();
            var phone = $('input.phone').val();

            if (name == '') {
                $('input.name').addClass('error');
                $('input.name').keypress(function(){
                    $('input.name').removeClass('error');
                });
            }
            if (email == '') {
                $('input.email').addClass('error');
                $('input.email').keypress(function(){
                    $('input.email').removeClass('error');
                });
            } …
