javascript倒計時

javascript倒計時。首先我們要設置倒計時時間格式，方法如下：

function currTimeForm(currTime){
    var day = Math.floor(currTime/60/60/24);
    var hour = Math.floor(currTime/60/60%24);
    var min = Math.floor(currTime/60%60);
    var sec = Math.floor(currTime%60);
    if(day<10){
        day = "0"+day;
    }
    if(hour<10){
        hour = "0"+hour;
    }
    if(min<10){
        min = "0"+min;
    }
    if(sec<10){
        sec = "0"+sec;
    }
        return day+":"+hour+":"+min+":"+sec;
}

這個倒計時時間格式：00：00：00：00。
倒計時方法：

function DateFormate(time){
    var dateObj = parseInt(time);
    var intervel = setInterval(function(){
        var currTime = dateObj-parseInt(new Date().getTime()/1000);
        if(currTime == 0){
            clearInterval(intervel);
            window.location.reload();
        }else if(currTime>0){
            document.getElementById("daojiTime").innerHTML = currTimeForm(currTime);
        }else{
            clearInterval(intervel);
            alert("結束了！");
        }
    },1000);
}
