JS實現簡單倒計時

標籤：

/*倒計時*/var downTime =  function (endTime,obj,callback){    /*基本判斷*/    if(!endTime || typeof endTime !== "string") return false;    /*基本判斷*/    if(!obj || typeof obj !== "object") return false;    /*擷取日期的毫秒*/    var endTime = Date.parse(endTime);    /*定時器*/    setInterval(function () {        var nowTime  = +new Date();        /*2個時間的差 毫秒*/        var minus =endTime - nowTime;        /*相差的天數*/        var day = parseInt(minus/1000/60/60/24);        /*相差的小時*/        var hours = parseInt(minus/1000/60/60%24);        /*相差的分鐘*/        var mintue = parseInt(minus/1000/60%60);        /*擷取相差的秒*/        var second = parseInt(minus/1000%60);        obj[0].innerHTML = parseInt(hours/10);        obj[1].innerHTML = hours%10;        obj[3].innerHTML = parseInt(mintue/10);        obj[4].innerHTML = mintue%10;        obj[6].innerHTML = parseInt(second/10);        obj[7].innerHTML = second%10;    },1000);    callback && callback();};
