},

jQuery.extend(jQuery.validator.messages,{
required: "必选字段",remote: "请修正该字段",email: "请输入正确格式的电子邮件",url: "请输入合法的网址",date: "请输入合法的日期",dateISO: "请输入合法的日期 (ISO).",number: "请输入合法的数字",digits: "只能输入整数",creditcard: "请输入合法的信用卡号",equalTo: "请再次输入相同的值",accept: "请输入拥有合法后缀名的字符串",maxlength: jQuery.validator.format("请输入一个 长度最多是 {0} 的字符串"),minlength: jQuery.validator.format("请输入一个 长度最少是 {0} 的字符串"),rangelength: jQuery.validator.format("请输入 一个长度介于 {0} 和 {1} 之间的字符串"),range: jQuery.validator.format("请输入一个介于 {0} 和 {1} 之间的值"),max: jQuery.validator.format("请输入一个最大为{0} 的值"),min: jQuery.validator.format("请输入一个最小为{0} 的值")
});
推荐做法，将此文件放入 messages_cn.js 中，在页面中引入：
$().ready(function() {
$("#signupForm").validate();
});
<form id="signupForm" method="get" action="">
