jQuery Validate （1.时间比较 2.验证身份证号）

1.结束时间不能早于开始时间

html 代码：

<input type="text" class="form-control input-date" id='starttime' required/>
<input type="text" class="form-control input-date" id='endtime' data-rule-compareDate="true"/>

JS 代码：

 //引入JS库
 <script src="http://static.runoob.com/assets/jquery-validation-1.14.0/lib/jquery.js"></script>
 <script src="http://static.runoob.com/assets/jquery-validation-1.14.0/dist/jquery.validate.min.js"></script>
 //结束时间不能大于开始时间
 $.validator.addMethod("compareDate", function(value, element) {  
      var startDate = $("#starttime").val();                        
      var date1 = new Date(Date.parse(startDate.replace("-", "/")));            
      var date2 = new Date(Date.parse(value.replace("-", "/")));            
      return date1 <= date2;        
 },"结束时间不能早于开始时间");

2.验证身份证号码

html 代码：

<input type="text" id="useridcard" placeholder="请输入人员证号" data-rule-isIdCardNo="true"/>

JS 代码：

 // 身份证号码验证	
$.validator.addMethod("isIdCardNo", function(value, element) {		
     return this.optional(element) || isIdCardNo(value);	
 }, "请正确输入您的身份证号码");
 
//身份证验证 引入的方法
function isIdCardNo(num) {
      var factorArr = new Array(7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5,8, 4, 2, 1);
      var parityBit = new Array("1", "0", "X", "9", "8", "7", "6", "5", "4","3", "2");
      var varArray= new Array();
      var intValue;
      var lngProduct = 0;
      var intCheckDigit;
      var intStrLen = 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;
       }
    }
    return true;
}

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
    return true
}


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);
    var iaMonthDays = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30,31]
    if (year< 1700 || year > 2500) return false
    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
    return true
