# wx-drawer
小程序模仿QQ6.0侧滑菜单 wx-drawer 😃

## 其他组件
- [wx-alphabetical-listview带字母滑动的列表](https://github.com/zhongjie-chen/wx-alphabetical-listview)
- [wx-scrollable-tab-view可滚动的tabview](https://github.com/zhongjie-chen/wx-scrollable-tab-view)

## 截屏

### 电脑上的截屏
![](https://github.com/zhongjie-chen/blog/blob/gh-pages/img/wx-drawer.gif?raw=true)

## 功能

- [x] 模仿QQ6.0侧滑菜单功能，小程序实现
- [x] 在android ios 平台测试过，确保真实环境一致
- [ ] 小程序目前不支持组件化；后期会抽离一些公共的东西，让使用起来更加方便

## 如何使用

1. 复制page下的文件夹到自己项目中
2. 配置app.json
3. 编译

### 其它
