如何制作倒计时器?
当用户加载页面时,时钟开始倒计时,当时间结束时,将浏览器重定向到新页面。

像这样的吗?
<div id="countDiv"></div>
<script>
function countDown (count) {
if (count > 0) {
var d = document.getElementById("countDiv");
d.innerHTML = count;
setTimeout (function() { countDown(count-1); }, 1000);
}
else
document.location = "someotherpage.html";
}
countDown(5);
</script>
使用纯JavaScript,您可以像这样做:
window.onload=function(){ // makes sure the dom is ready
setTimeout('function(){document.location = "http://www.google.com"}', 10000) // redirects you to google after 10 seconds
}
<p>
When this counter reaches 0, you will be redirected to
<a href="http://path.to.wherever/" id="redirectme">wherever</a>.
<span id="counter">10</span>
</p>
<script type="text/javascript">
(function(){
var
counter = document.getElementById("counter"),
count = parseInt(counter.innerHTML),
url = document.getElementById("redirectme").href,
timer;
function countdown() {
count -= 1;
counter.innerHTML = count;
if (count <= 0) {
clearTimeout(timer);
window.location.assign(url);
}
}
timer = setInterval(countdown, 1000); // 1000 ms
})();
</script>
setTimeout(function() { countDown(count-1); }, 1000);
