messages: {
??? required:"This field is required.",
??? remote:"Please fix this field.",
??? email:"Please enter a valid email address.",
??? url: "Pleaseenter a valid URL.",
??? date:"Please enter a valid date.",
??? dateISO:"Please enter a valid date (ISO).",
??? dateDE:"Bitte geben Sie ein g眉ltiges Datum ein.",
??? number:"Please enter a valid number.",
??? numberDE:"Bitte geben Sie eine Nummer ein.",
??? digits:"Please enter only digits",
??? creditcard:"Please enter a valid credit card number.",
??? equalTo:"Please enter the same value again.",
??? accept:"Please enter a value with a valid extension.",
??? maxlength:$.validator.format("Please enter no more than {0}characters."),
??? minlength:$.validator.format("Please enter at least {0} characters."),
??? rangelength:$.validator.format("Please enter a value between {0} and {1}characters long."),
??? range:$.validator.format("Please enter a value between {0} and{1}."),
??? max:$.validator.format("Please enter a value less than or equal to{0}."),
??? min:$.validator.format("Please enter a value greater than or equal to{0}.")
},

如需要修改，可在js代码中加入：

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
<script src="../js/messages_cn.js"type="text/javascript"></script>

<scriptsrc="../js/jquery.js"type="text/javascript"></script>
<script src="../js/jquery.validate.js"type="text/javascript"></script>
<script src="./js/jquery.metadata.js"type="text/javascript"></script>

$().ready(function() {
?$("#signupForm").validate();
});

<form id="signupForm" method="get"action="">
???<p>
???????<labelfor="firstname">Firstname</label>
???????<input id="firstname" name="firstname"/>
???</p>
?<p>
??<labelfor="email">E-Mail</label>
??<inputid="email" name="email" name="password" type="password"/>
?</p>
?<p>
??<labelfor="confirm_password">确认密码</label>
??<inputid="confirm_password" name="confirm_password" type="password"type="submit"value="Submit"/>
???</p>
</form>

使用method="get"action="">
???<p>
???????<labelfor="firstname">Firstname</label>
???????<input id="firstname" name="firstname"/>
???</p>
?<p>
??<labelfor="email">E-Mail</label>
??<inputid="email" name="email" />
?</p>
?<p>
??<labelfor="password">Password</label>
??<inputid="password" name="password" type="password"/>
?</p>
?<p>
??<labelfor="confirm_password">确认密码</label>
??<inputid="confirm_password" name="confirm_password" type="password"/>
?</p>
???<p>
???????<input type="submit"value="Submit"/>
???</p>
</form>

required:true 必须有值
required:"#aa:checked"表达式的值为真，则需要验证
required:function(){}返回为真，表时需要验证
后边两种常用于，表单中需要同时填或不填的元素
