一、首先，引用（已下载在本地）：

二、默认校验规则
(1)required:true 必输字段
(2)remote:"check.php" 使用ajax方法调用check.php验证输入值
(3)email:true 必须输入正确格式的电子邮件
(4)url:true 必须输入正确格式的网址
(5)date:true 必须输入正确格式的日期
(6)dateISO:true 必须输入正确格式的日期(ISO)，例如：2009-06-23，1998/01/22 只验证格式，不验证有效性
(7)number:true 必须输入合法的数字(负数，小数)
(8)digits:true 必须输入整数
(9)creditcard: 必须输入合法的信用卡号
(10)equalTo:"#field" 输入值必须和#field相同
(11)accept: 输入拥有合法后缀名的字符串（上传文件的后缀）
(12)maxlength:5 输入长度最多是5的字符串(汉字算一个字符)
(13)minlength:10 输入长度最小是10的字符串(汉字算一个字符)
(14)rangelength:[5,10] 输入长度必须介于 5 和 10 之间的字符串")(汉字算一个字符)
(15)range:[5,10] 输入值必须介于 5 和 10 之间
(16)max:5 输入值不能大于5
(17)min:10 输入值不能小于10

三、默认的提示（在jquery.validate.js中）
messages: {
required: "This field is required.",
remote: "Please fix this field.",
email: "Please enter a valid email address.",
url: "Please enter a valid URL.",
date: "Please enter a valid date.",
dateISO: "Please enter a valid date (ISO).",
dateDE: "Bitte geben Sie ein gltiges 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，在jquery.validate.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")
});

四、添加自定义验证方法：

//先（可用正则表达式）写自定义验证
jQuery.validator.addMethod(
"IsPhone", //规则名称
function(value, element) {
var Phone = /^1[3|4|5|7|8][0-9]{9}$/;
return this.optional(element) || (Phone.test(value));
},
"请输入正确的手机号码格式"
);

//然后再如同默认规则一样引用，如下图：

<script>
$.validator.setDefaults({
submitHandler: function() { alert("submitted!"); }
});

$().ready(function() {
// validate the comment form when it is submitted
$("#commentForm").validate();

// validate signup form on keyup and submit
$("#signupForm").validate({
rules: {
firstname: "required",
lastname: "required",
username: {
required: true,
minlength: 2
},
password: {
required: true,
minlength: 5
},
confirm_password: {
required: true,
minlength: 5,
equalTo: "#password"
},
email: {
required: true,
email: true
},
topic: {
required: "#newsletter:checked",
minlength: 2
},
agree: "required"
},
messages: {
firstname: "Please enter your firstname",

});

// propose username by combining first- and lastname
$("#username").focus(function() {
var firstname = $("#firstname").val();
var lastname = $("#lastname").val();
if(firstname && lastname && !this.value) {
this.value = firstname + "." + lastname;
}
});

//code to hide topic selection, disable for demo
var newsletter = $("#newsletter");
// newsletter topics are optional, hide at first
var inital = newsletter.is(":checked");
var topics = $("#newsletter_topics")[inital ? "removeClass" : "addClass"]("gray");
var topicInputs = topics.find("input").attr("disabled", !inital);
// show when newsletter is checked
newsletter.click(function() {
topics[this.checked ? "removeClass" : "addClass"]("gray");
topicInputs.attr("disabled", !this.checked);
});
});
</script>
