使用方法:

只需引用jQuery库和YesTop插件,然后一句代码就可以实现返回顶部:

引用代码:

<script type="text/javascript" src="http://hovertree.com/ziyuan/jquery/jquery-1.11.3.min.js"></script>
<script type="text/javascript" src="http://hovertree.com/texiao/yestop/inc/jquery.yestop.js"></script>

使用代码:

<script type="text/javascript">
   $(document).ready(function () { $.fn.yestop(); })
</script>

也就是:

$.fn.yestop();

这句代码就可以了。

当然还有高级的设置,如换图片,设置图标为圆形,设置位置,设置时间等等。详情请查看其他Demo。

完整代码,保存到HTML文件就可以体验效果:

<!DOCTYPE html>

<head><meta charset="UTF-8">
