比较简单的日期字符串(例如console.log(“24.3.2018”<“20.3.2017”))

function CompareDate(dateStr1,dateStr2) {
       var dateArry1 = dateStr1.split(".");
        var dateArry2 = dateStr2.split(".");
        //JavaScript counts months from 0 index so we have to do -1:January - 0, February - 1, and so on..... 
       var dateOne = new Date(dateArry1[2], dateArry1[1]-1, dateArry1[0]); //Year, Month, Date
      var dateTwo = new Date(dateArry2[2], dateArry2[1]-1, dateArry2[0]); //Year, Month, Date
      if (dateOne > dateTwo) {
          console.log("Date One is greather then Date Two.");
          return true;
       }else if(dateOne < dateTwo) {
         console.log("Date Two is greather then Date One.");
         return false;
      }else if(dateOne.toDateString() === dateTwo.toDateString()) {
         console.log("Date are same.");
         return false;
      }
      return false;
 }

console.log(CompareDate("23.3.2018","24.3.2018"));
//VM16380:1 false
