倒计时：
var date = new Date('2022-5-14 15:00:00');
var now = new Date();
var times = (date - now) / 1000;
var T = parseInt(times / 60 / 60 / 24);
T = T < 10 ? '0' + T : T;
var H = parseInt(times / 60 / 60 % 24);
H = H < 10 ? '0' + H : H;
var M = parseInt(times / 60 % 60);
M = M < 10 ? '0' + M : M;
var S = parseInt(times % 60);
S = S < 10 ? '0' + S : S;
console.log(T +' ' + H + ':' + M + ':' + S);
