jquery.validate----身份证号码验证

一、js文件中先写入的文件

$(document).ready(function () {
   jQuery.validator.addMethod("isIdCardNo", function (value, element){
       return this.optional(element) || isIdCardNo(value);
    },"请正确输入您的身份证号码");
});

//增加身份证验证
function isIdCardNo(num) {
    varfactorArr = new Array(7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5,8, 4, 2, 1);
    varparityBit = new Array("1", "0", "X", "9", "8", "7", "6", "5", "4","3", "2");
    var varArray= new Array();
    varintValue;
    varlngProduct = 0;
    varintCheckDigit;
    varintStrLen = num.length;
    var idNumber= num;
    //initialize
    if((intStrLen != 15) && (intStrLen !=18)) {
       return false;
    }
    // check andset value
    for (i = 0;i < intStrLen; i++) {
       varArray[i] = idNumber.charAt(i);
       if ((varArray[i] < '0' || varArray[i]> '9') && (i != 17)){
           return false;
       } else if (i < 17) {
           varArray[i] = varArray[i] * factorArr[i];
       }
    }

    if(intStrLen == 18) {
       //check date
       var date8 = idNumber.substring(6, 14);
       if (isDate8(date8) == false) {
           return false;
       }
       // calculate the sum of the products
       for (i = 0; i < 17; i++) {
           lngProduct = lngProduct + varArray[i];
       }
       // calculate the check digit
       intCheckDigit = parityBit[lngProduct % 11];
       // check last digit
       if (varArray[17] != intCheckDigit) {
           return false;
       }
    }
    else{       //length is 15
       //check date
       var date6 = idNumber.substring(6, 12);
       if (isDate6(date6) == false) {
           return false;
       }
    }
    returntrue;
}
function isDate6(sDate) {
    if(!/^[0-9]{6}$/.test(sDate)) {
       return false;
    }
    var year,month, day;
    year =sDate.substring(0, 4);
    month =sDate.substring(4, 6);
    if (year< 1700 || year > 2500) returnfalse
    if (month< 1 || month > 12) return false
    returntrue
}

function isDate8(sDate) {
    if(!/^[0-9]{8}$/.test(sDate)) {
       return false;
    }
    var year,month, day;
    year =sDate.substring(0, 4);
    month =sDate.substring(4, 6);
    day =sDate.substring(6, 8);
    variaMonthDays = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30,31]
    if (year< 1700 || year > 2500) returnfalse
    if (((year %4 == 0) && (year % 100 != 0)) ||(year % 400 == 0)) iaMonthDays[1] = 29;
    if (month< 1 || month > 12) return false
    if (day< 1 || day > iaMonthDays[month - 1])return false
    returntrue
}
二、调用插件后，js添加的代码。

$(function() {
 $("#active").validate({
  rules: {
   FMobileNumber:{
    required:true,
    number:true,
    minlength:7
   }
  },
  messages: {
   FMobileNumber:{   
    required:"必须填写",
    number:'请输入正确的手机号,必须为数字',
    minlength:jQuery.format("手机至少包含{0}个字")
   }
  },
  errorPlacement: function(error,element) {
   error.appendTo(element.parent().next().next());
  }
 });
});

三、html代码
