required:function(){}的示例如下：
<meta http-equiv=”Content-Type” content=”text/html; charset=UTF-8″ />
<script language=”JavaScript” type=”text/JavaScript” src=”jquery-1.6.1.js”></script>
<script language=”JavaScript” type=”text/JavaScript” src=”jquery.validate.min.js”></script>
<script language=”JavaScript” type=”text/JavaScript” src=”jquery.metadata.js”></script>
<script>
$().ready(function() {
$(“#signupForm”).validate({
rules:
{
firstname: “required”,
email:
{
required: function()
{
return true;
},
email: function()
{
return false;
}
}
},
messages:
{
firstname: “请输入姓名”,
email:
{
required: “请输入Email地址”,
email: “请输入正确的email地址”
}
}
});
});
//messages处，如果某个控件没有message，将调用默认的信息
