自学的js，准备用js写一个倒计时网页，单个倒计时已经写好了，但是多个倒计时遇到了麻烦。
据我观察，我写的js函数只在一个倒计时中调用了，如何同时多次调用呢？

function timeee(tim) {

//为了实现每秒刷新，写的很难看...
function timer(time) {
var start = new Date(time).getTime();
var t = start - new Date().getTime();
var h = ~~(t / 1000 / 60 / 60 % 24);
if (h < 10) {
h = "0" + h;
}
var m = ~~(t / 1000 / 60 % 60);
if (m < 10) {
m = "0" + m;
}
var s = ~~(t / 1000 % 60);
if (s < 10) {
s = "0" + s;
}
document.getElementById('d').innerHTML = ~~(t / 1000 / 60 / 60 / 24);
document.getElementById('h').innerHTML = h;
document.getElementById('m').innerHTML = m;
document.getElementById('s').innerHTML = s;
}谢谢各位大神！
html5
window.onload = xxx;这种赋值的方式，后面的会覆盖前面的，所以永远只有最后一个有效想要多个都生效，使用
addEventListener事件监听即可
