jQuery show setTimeout timer
提问by sophistry
I'm trying to build a simple countdown application. Is it possible to show the timer value on setTimeout, or would I have to use a for loop?
我正在尝试构建一个简单的倒计时应用程序。是否可以在 setTimeout 上显示计时器值，还是必须使用 for 循环？
Thanks!
谢谢！

with setTimeout:
与setTimeout：
var n = 100;
setTimeout(countDown,1000);
function countDown(){
n--;
if(n > 0){
setTimeout(countDown,1000);
}
console.log(n);
}
or using setInterval:
或使用setInterval：
var n = 100;
var tm = setInterval(countDown,1000);
function countDown(){
n--;
if(n == 0){
clearInterval(tm);
}
console.log(n);
}

<script>
var timer = setInterval("mytimer()",1000);
seconds = 0;
function mytimer()
{
document.getElementById("div_timer").innerHTML = seconds; // this is the same as $("div_timer").html(timer) in jquery.
seconds++;
}
</script>
<body>
<div id="div_timer"></div>
</body>
