js 日期比较

参考一：
function checkDate(){
var startTime=document.getElementById("startTime").value; //获得系统日期的文本值
var endTime=document.getElementById("endTime").value; //获得用户选择的日期文本值
var aStart=startTime.split('-'); //转成成数组，分别为年，月，日，下同
var aEnd=endTime.split('-');
var startDate = aStart[0]+"/" + aStart[1]+ "/" + aStart[2];
var endDate = aEnd[0] + "/" + aEnd[1] + "/" + aEnd[2];
if (startDate > endDate) {
$("#moneyMessage").html("<font color=red>开始日期必须小于结束日期</font>");
return false;
}
return true;
  }

参考二：
<SCRIPT LANGUAGE="JavaScript">

</SCRIPT>

月<input type="text" id="month" value="6">
日期 <input type="text" id="date" value="2009-11-01">
<input type="button" value="submit" >

function dateDifferent()
{
var time1 = document.form1.time1.value;
var time2 = document.form1.time2.value;
var date1 = new Date(time1);
var date2 = new Date(time2);
//var DiffDate = DateDiff("d",time1,time2);

//long begintime = begindate.gettime();

参考四：
function CompareDate(inputDate){
   var currentDate = new Date();
   if(currentDate.getYear() > inputDate.getYear())
   return -1;
   else if(currentDate.getYear() < inputDate.getYear())
   return 1;

   if(currentDate.getMonth() > inputDate.getMonth())
   return -1;
   else if(currentDate.getMonth() < inputDate.getMonth())
   return 1;

   if(currentDate.getDate() > inputDate.getDate())
   return -1;
   else if(currentDate.getDate() < inputDate.getDate())
   return 1;

   return 0;
}

function Compare() {
var sday = document.getElementById("day").value.split('-');
   var inputDate = new Date(sday[0],sday[1]-1,sday[2]);
   if(isNaN(inputDate)){
   alert("不是日期");
return;
   }
   var result = CompareDate(inputDate);
   if(result < 0)
   alert(inputDate.toLocaleString() + "小于当前日期");
   else if(result > 0)
   alert(inputDate.toLocaleString() + "大于当前日期");
   else
   alert(inputDate.toLocaleString() + "等于当前日期");
}
参考五：
JavaScript代码

function dateCompare(startdate,enddate)
{
var arr=startdate.split("-");
var starttime=new Date(arr[0],arr[1],arr[2]);
var starttimes=starttime.getTime();

var arrs=enddate.split("-");
var lktime=new Date(arrs[0],arrs[1],arrs[2]);
var lktimes=lktime.getTime();

if(starttimes>=lktimes)
{
return false;
}
else
return true;

}

第二种：

JavaScript代码
//验证是否合法日期
function CheckDate(strDate){
   if(strDate.length>0){
   var reg= /^(\d )-(\d{1,2})-(\d{1,2}) (\d{1,2}):(\d{1,2}):(\d{1,2})$/;
   if(!reg.test(strDate)){
      return false;
   }
   }
   return true;
}



function isStartEndDate(startDate,endDate){
   //alert(startDate "===" endDate);
   if(startDate.length>0&&endDate.length>0){
   var startDateTemp = startDate.split(" ");
   var endDateTemp = endDate.split(" ");
   var arrStartDate = startDateTemp[0].split("-");
   var arrEndDate = endDateTemp[0].split("-");
   var arrStartTime = startDateTemp[1].split(":");
   var arrEndTime = endDateTemp[1].split(":");
   var allStartDate = new Date(arrStartDate[0],arrStartDate[1],arrStartDate[2],arrStartTime[0],arrStartTime[1],arrStartTime[2]);
   var allEndDate = new Date(arrEndDate[0],arrEndDate[1],arrEndDate[2],arrEndTime[0],arrEndTime[1],arrEndTime[2]);
   if(allStartDate.getTime()>allEndDate.getTime()){
   return false;
   }
   }
   return true;
}



function checkAskDate(StartDate,EndDate){
   if(!CheckDate(StartDate.value)){
   alert("开始日期格式不正确!\n正确格式为:2004-01-01 00:00");
   StartDate.focus();
   return false;
   }
   if(!CheckDate(EndDate.value)){
   alert("结束日期格式不正确!\n正确格式为:2004-01-01 00:00");
   EndDate.focus();
   return false;
   }
   if(!isStartEndDate(StartDate.value,EndDate.value)){
   alert("开始日期不能大于结束日期");
   return false;
   }
   return true;
}
