如何用网站模板百度seo关键词优化排名

看了下市场的代码，要么写的不怎么好，要么过于复杂。于是把市场的代码下下来了自己改。200行代码撸了个弹出层组件。兼容H5和APP。

功能：

  1)只支持上下左右4个方向的弹层不支持侧边靠齐

  2)不对屏幕边界适配

  3)支持弹层外边点击自动隐藏

  4)支持3种内容模式：

    1. 弹出提示文本

    2. slot内容占位

    3. 支持菜单模式

BWT：弹层外点击自动隐藏基于unibest框架的页面模板技术，这里就不放代码了，自己想想怎么弄😏 。提示：使用事件总线模式，放出的代码也提示了部分用法。

效果，H5下：

APP下：

小程序下：

对了，菜单的图标支持还没写。等用到的时候再加上去，代码放这存档，后面再更新:）
