微信小程序实现弹出菜单功能

前端之家收集整理的这篇文章主要介绍了微信小程序实现弹出菜单功能前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

需求

点击标签栏按钮,向下弹出菜单,再次点击,收回菜单

解决的问题

  1. 标签栏三栏样式,标签栏固定不动;
  2. 点击标签栏弹出菜单,并且出现透明遮罩;
  3. 遮罩优先级在弹出框之下;
  4. 弹出框内标签的设置;
  5. 滚动栏滚动条的隐藏

如何解决

  1. 弹性布局,横向,三者平分整栏;
  2. 状态监听点击事件,数据控制hide或者show,通过rgba设置透明度
  3. 弹出框设置z-index;
  4. 弹性布局flex 横向排列 超出后wrap 然后space-around控制间距
