每天多个固定时间倒计时

function Time(){
var NowTime = new Date();
var ntime=NowTime.getFullYear()+‘/‘+(NowTime.getMonth()+1)+‘/‘+NowTime.getDate()
var ntime2=NowTime.getFullYear()+‘/‘+(NowTime.getMonth()+1)+‘/‘+(NowTime.getDate()+1)
var EndTime= new Date(ntime+ ‘ 9:30:00‘);
var EndTime2= new Date(ntime+ ‘ 13:30:00‘);
var EndTime3= new Date(ntime2+ ‘ 9:30:00‘);
cha1=EndTime.getTime() - NowTime.getTime();
cha2=EndTime2.getTime() - NowTime.getTime();
cha3=EndTime3.getTime() - NowTime.getTime();
if(cha1>0){
t=cha1
}
if(cha1<=0&&cha2>0){
t=cha2
}
if(cha2<=0&&cha3>0){
t=cha3
}
var d=Math.floor(t/1000/60/60/24);
var h=Math.floor(t/1000/60/60%24);
var m=Math.floor(t/1000/60%60);
var s=Math.floor(t/1000%60);
document.getElementById("pro_djs").innerHTML="倒计时"+h +"时"+m +"分"+s +"秒";
}

setInterval(Time,1000);
