wordpress-为博客添加倒计时功能。

倒计时也行以后会用得到,在这记录下来吧!

 

创建js文件:

将下面的代码复制进去。

可以将下面的代码放在自定义HTML小工具,也可以放在想要显示的地方。

<style type="text/css">
.zzsc-content{
padding-left:10%;
}
#clock{
font-family: 'Days One',"Microsoft YaHei", Arial,sans-serif;
font-size: 2em;
}
</style>
<div class="zzsc-content bgcolor-8">
<span id="clock"></span>
</div>

<script type="text/javascript" src="https://www.9izy.net/countdown.js"></script> //此处修改你的地址
<script type="text/javascript">
$(function(){
$('#clock').countdown('2021/5/19', function(event) {
$(this).html(event.strftime('%D 天 %H:%M:%S'));
});
})
</script>
