问题描述

frmdate = document.getElementById("txt_fromdate").value;
          todt = document.getElementById("txt_todate").value;
var date1 = new Date(frmdate);
         var date2 = new Date(todt);
         var date3 = new Date();
         var date4 = date3.getMonth() + "/" + date3.getDay() + "/" + date3.getYear();
         var currentDate = new Date(date4);
         if (date2 > currentDate) {
             alert("To date can not be greater than current date");
             return false;
         }

推荐答案

熟悉 JavaScript中的日期对象 [ ^ ]并为每个日期构造一个，并使用普通比较运算符进行比较。

Get familiar with the Date object in JavaScript[^] and construct one for each date and compare them using normal comparison operators.
