大家好,我在这里发现了一些有用的东西:
我试图按照以下方式运行,但由于某些原因我在网页上没有收到任何输出 - 我是一个完整的新手,所以如果这很简单许多道歉,但如果有任何人那么好,请指点我在正确的方向 - 代码如下:
<script type="text/javascript">
$(function() {
var count = localStorage.getItem('count') || 20,
countdown = setInterval(function() {
localStorage.setItem('count', count);
$("p.countdown").html(count + " seconds remaining!");
if (count == 0) {
clearInterval(countdown);
localStorage.removeItem('count');
window.location = 'http://stackoverflow.com/';
}
count--;
}, 1000);
});
</script>
<p class="countdown"></p>
非常感谢提前

你唯一想念的就是调用jQuery库
<script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<script type="text/javascript">
$(function() {
var count = localStorage.getItem('count') || 20;
var countdown;
countdown = setInterval(function() {
--count;
if(count>0){
localStorage.setItem('count', count);
$("p.countdown").html(count + " seconds remaining!");
}else{
clearInterval(countdown);
localStorage.removeItem('count');
window.location = 'http://stackoverflow.com/';
}
}, 1000);
});
</script>
<p class="countdown"></p>
