// 倒计时
function countDown(time){
    var inputTime = +new Date(time);  //用户输入时间戳
    var nowTime = +new Date();        //现在输入时间戳
    var times = (inputTime - nowTime)/1000; //总秒数
    var d = parseInt(times/60/60/24);  //天
    d = d < 10 ? '0' + d : d;         
    var h = parseInt(times/60/60%24);  //时
    h = h < 10 ? '0' + h : h;
    var m = parseInt(times/60%60);     //分
    m = m < 10 ? '0' + m : m;
    var s = parseInt(times%60);        //秒
    s = s < 10 ? '0' + s : s;
    return d+'天'+h+'时'+m+'分'+s+'秒'
