jQuery的validate验证功能十分强大，但是能够自定义验证方法更具有灵活性，所以我只是把自定义的说明一下。
添加自定义方法是使用jquery的jQuery.validator.addMethod方法，这个方法的完整定义如下：
jQuery.validator.addMethod("myValidateName", function(value, element, param) {
//myValidateName是自己定义的验证方法值
//value是指当前校验域的值
//element是指当前检验的域
//param是指在rules中设定的参数
},$.validator.format("xxx"));定义完之后，就可以通过在页面中声明和调用了。调用方法如下：
var validator = $("#formName").validate({//formName是form的名字
submitHandler: function(form) { //提交时候调用的方法
formSubmit();//调用成功后的处理函数
} ,
rules: {
inputName1: "myValidateName",//如果只用一个验证方式的话，需要用引号标记上，而且这种方式是认为强制执行的，也就是一定要验证的
inputName2: {//如果想使用多种验证方式，就需要使用花括号标记上，且逗号隔开，记住：最后一项不要有逗号
myValidateName1: true,//这种是强制执行的验证
myValidateName2: function(){if(某条件满足){return true;}else{return false;}},//这种根据条件判断要不要验证，更佳的灵活，用在多条件输入的时候极为方便
myValidateName3: [//使用方括号的是对于普通验证的更佳高级方法，这种方法也十分好用
function(){if(某条件满足){return true;}else{return false;}},//同上，验证条件判断，条件不满足，本验证就不生效
rangeValue1,//阈值控制值，这个值可以有任意多个，就看你的验证方法中是怎样声明的了
rangeValue2//阈值控制值
]
}
},
messages: {//验证到不合法的值的提示信息，如果不加这部分，就会执行你声明函数的时候的默认提示：“xxx”，就是在$.validator.format("xxx"));中声明的那个提示
inputName1: "AAA",//这种写法是将所有验证不通过的全部提示AAA
inputName2: {//这种就是更佳详细的提示，当然也可以使用上面的这种方式，无论myValidateName1，2还是3，只要有不通过的，都会提示同一条信息。
myValidateName1:"BBB",//但是如果详细些的提示，就需要用花括号标记上，并且内部用逗号隔开，且最后一个后面不能有逗号，就相当于使用数组的方式
myValidateName2:"CCC",
myValidateName3:"DDD"//这里后面不能有逗号了，不然在有些浏览器中会报错
}
},
errorPlacement: function(error, element) {//这里定义的是出错或者叫提示信息出现的位置
error.insertAfter(element.parent().find('label:first'));//这句话的意思就是说，在验证不通过的那个标签上面的父节点开始向下找到第一个lable标签的后面，进行插入
}, //就是这样，如下面：
//<div>
// <lable>mylablename</lable> 这里是你定义的一个lable标签
// <input name="inputName1" type="text" />
//</div>
//如果验证不通过，那么就会从名字为inputName1的标签开始查找它的父标签，也就是div，然后再从div开始乡下找到第一个lable标签，就是mylablename那行，然后再在这行之后进行插入错误信息
//执行之后，大概就是下面的样子：
//<div>
// <lable>mylablename</lable> 这里是你定义的一个lable标签
// <lable>AAA</lable>这里是你验证不通过时的提示信息
// <input name="inputName1" type="text" />
//</div>
success: function(label) {
// set as text for IE
label.html(" ").addClass("ok");//这个就是如果验证通过了，就再在提示的那行lable标签中添加名字为ok的class类，用于改变css样式，至于名字随便起
}
});下面举一个具体的例子
首先定义自己的验证方法，定义到myvalidate.js中，内容如下
$(document).ready(function(){
//验证IP地址
jQuery.validator.addMethod("isIP", function(value, element, param) {
if ( !this.depend(param, element) )//这个判断必须要加上，这个是判断是否要执行这个检测，就是对于rules中定义的isIP后面的条件的判断，如果不满足，就不再验证了
return "dependency-mismatch"; //所以我说，这里必须要加上，其实也不是必须，但是这样会十分灵活，根据你的意愿让它到底何时验证
var reg = new RegExp(getReg("ip"),"i"); //这里是一个正则表达式，具体是怎样的，就不列出来了，不懂的，自己百度一下正则表达式，很简单的
return this.optional(element) || (reg.test(value)); //前面optional这部分我也不清楚是啥意思，但是看官方的js脚本都是加上的，那么咱们也照样加上，
//然后后面的这部分才是你真正的判断，注意：只有return false的时候，才会显示你的提示，如果返回的是true，那么就进入到了前面success函数哪里
}, $.validator.format("not IP"));//这里就是如果没有通过验证要提示给用户的信息，显示位置由你声明调用的时候规定，在前文中有说明
//验证在一定范围内的数值，这个例子就比较麻烦的那个，也就是前面说的是用方括号的那个
jQuery.validator.addMethod("isMyRange", function(value, element, param) {
if ( !this.depend(param[0], element) )//这里的param[0]，就代表调用定义中的方括号中的第一个元素，如果按照前面myValidateName3的例子的话，它就是对应function那一行
return "dependency-mismatch";
var reg = new RegExp(getReg("integer65535"),"i"); //因为是判断数值，所以首先用正则表达式判断一下是不是数值，别验证半天，结果人家用户根本就没输入数值
return this.optional(element) || (reg.test(value) && value >= param[1] && value <= param[2]);//这里的param[1]和param[2]就分别代表着第二和第三个元素，也就是rangeValue1和rangeValue2，那么这个验证的目的就是验证在rangeValue1和rangeValue2之间的数值
}, $.validator.format("请输入 {1} 和 {2} 之间的数值"));//这里也需要注意，其中的{1}和{2}是分别代表你定义的rangeValue1和rangeValue2这两个值，其实，这里的{1}和{2}就是你在rulse中的那个方括号中定义的元素的下标，有过c语言或者程序开发的肯定再熟悉不过了，对，就是数组嘛
}); 下面在html页面中添加定义
比如我有个页面，叫test.html，内容如下：
<html>
<script type="text/javascript" src="js/jquery-1.4.2.min.js"></script><!-- 先要包含jquery库 -->
<script type="text/javascript" src="js/jquery.validate.js"></script><!-- 还要包含jquery.validate库 -->
<script type="text/javascript" src="js/myvalidate"></script><!-- 最后才是你自己定义的库 -->
<script type="text/javascript">
$(document).ready(function(){//开始声明验证方法
var validator = $("#myform").validate({
submitHandler: function(form) { //提交时候调用的方法
formSubmit();
} ,
rules: {
myipaddr: {
isIP: "#myradio_on:checked"//这里就是说当id为myradio_on的radio元素被选中的时候开始验证
},
mycount: {
isMyRange: [
"#myradio_on:checked",//同上
200,
800
]
}
},
//这里我省略掉了message，使用默认的提示，也就是我定义验证方法时给出的提示
// the errorPlacement has to take the layout into account
errorPlacement: function(error, element) {
error.insertAfter(element.parent().find('label:first'));
},
// set new class to error-labels to indicate valid fields
success: function(label) {
// set as text for IE
label.html(" ").addClass("ok");
}
});
});
</script>
<body>
<form name="myform" id="myform" method="post" action="myaction.html">
<div>
<p>
<label>是否验证</label><br/>
<input type="radio" name="validate" id="validate_on"/>
<input type="radio" name="validate" id="myradio_off"/>
<label for="myradio_off">算了</label>
</p>
</div>
<div>
<p>
<label>IP验证</label><br/>
<input type="text" name="myipaddr" id="myipaddr"/>
</p>
</div>
<div>
<p>
<label>Count验证</label><br/>
<input type="text" name="mycount" id="mycount"/>
</p>
</div>
</form>
</body>
</html>
到此一个完整的验证就出来了，你可以试一下，现在感觉确实很强大，如果有错误，希望大家指正，相互学习
下面附注一下jquery.validate.js文件中的内容，有部分有些改动，并非原版官方的，但是绝大多数都是一样的，大家可以看看，相信一定能学到很多东西
