// 手机号码验证  
jQuery.validator.addMethod("mobile", function(value, element) \{  
    var length = value.length;  
    var mobile =  /^(((13\[0-9\]\{1\})|(15\[0-9\]\{1\}))+\\d\{8\})$/  
    return this.optional(element) || (length == 11 && mobile.test(value));  
\}, "手机号码格式错误");    
   
// 电话号码验证    
jQuery.validator.addMethod("phone", function(value, element) \{  
    var tel = /^(0\[0-9\]\{2,3\}\\-)?(\[2-9\]\[0-9\]\{6,7\})+(\\-\[0-9\]\{1,4\})?$/;  
    return this.optional(element) || (tel.test(value));  
\}, "电话号码格式错误");  
   
// 邮政编码验证    
jQuery.validator.addMethod("zipCode", function(value, element) \{  
    var tel = /^\[0-9\]\{6\}$/;  
    return this.optional(element) || (tel.test(value));  
\}, "邮政编码格式错误");  
   
// QQ号码验证    
jQuery.validator.addMethod("qq", function(value, element) \{  
    var tel = /^\[1-9\]\\d\{4,9\}$/;  
    return this.optional(element) || (tel.test(value));  
\}, "qq号码格式错误");  
   
// IP地址验证  
jQuery.validator.addMethod("ip", function(value, element) \{  
    var ip = /^(?:(?:25\[0-5\]|2\[0-4\]\[0-9\]|\[01\]?\[0-9\]\[0-9\]?)\\.)\{3\}(?:25\[0-5\]|2\[0-4\]\[0-9\]|\[01\]?\[0-9\]\[0-9\]?)$/;  
    return this.optional(element) || (ip.test(value) && (RegExp.$1 < 256 && RegExp.$2 < 256 && RegExp.$3 < 256 && RegExp.$4 < 256));  
\}, "Ip地址格式错误");  
   
// 字母和数字的验证  
jQuery.validator.addMethod("chrnum", function(value, element) \{  
    var chrnum = /^(\[a-zA-Z0-9\]+)$/;  
    return this.optional(element) || (chrnum.test(value));  
\}, "只能输入数字和字母(字符A-Z, a-z, 0-9)");  
   
// 中文的验证  
jQuery.validator.addMethod("chinese", function(value, element) \{  
    var chinese = /^\[\\u4e00-\\u9fa5\]+$/;  
    return this.optional(element) || (chinese.test(value));  
\}, "只能输入中文");  
   
// 下拉框验证  
$.validator.addMethod("selectNone", function(value, element) \{  
    return value == "请选择";  
\}, "必须选择一项");  
   
// 字节长度验证  
jQuery.validator.addMethod("byteRangeLength", function(value, element, param) \{  
    var length = value.length;  
    for (var i = 0; i < value.length; i++) \{  
        if (value.charCodeAt(i) > 127) \{  
            length++;  
        \}  
    \}  
    return this.optional(element) || (length >= param\[0\] && length <= param\[1\]);  
\}, $.validator.format("请确保输入的值在\{0\}-\{1\}个字节之间(一个中文字算2个字节)"));  
   
使用：  
   
byteRangeLength\[3,4\]  
   
//整数位，小数位验证  
jQuery.validator.addMethod("decimal", function(value, element, param) \{return this.optional(element) || new RegExp("^-?\\\\d\{1," + (param.integer != null ? param.integer : "") + "\}" + (param.fraction != null ? (param.fraction > 0 ? "(\\\\.\\\\d\{1," + param.fraction + "\})?$" : "$") : "(\\\\.\\\\d+)?$")).test(value);\}, "numeric value out of bounds");  
   
使用：decimal: \{  
         integer: 12, //整数最大位数  
         fraction: 3  //小数点后最多位数  
        \}  
   
//整数位，小数位验证  
   
jQuery.validator.addMethod("decimal2", function(value, element, param) \{  
    return this.optional(element) || new RegExp("^-?\\\\d\{1," + (param\[0\] != null ? param\[0\] : "") + "\}" + (param\[1\] != null ? (param\[1\] > 0 ? "(\\\\.\\\\d\{1," + param\[1\] + "\})?$" : "$") : "(\\\\.\\\\d+)?$")).test(value);  
\}, $.validator.format("内容输入错误或者格式错误：整数位最多\{0\}位，小数位最多\{1\}位"));  
decimal2\[3,4\]
