小程序悬浮可移动按钮（taro框架）

不用自己再去计算按钮的位置直接使用

class App extends Components {

render () {

return (

<MovableArea style='height: 200px; width: 200px; background: red;'>

<MovableView style='height: 50px; width: 50px; background: blue;' direction='all'>旅行的意义</MovableView>

</MovableArea>

)

}

}

但是这里有一个小坑，对于初次使用来说，就是设定他的可移动区域，在底层的所有点击事件就无法点击，这里就要用到css中事件穿透属性：

pointer-events:none;

 /* 这个属性设置为none,让所有事件穿透过去 */

如下代码：

.movable-area{
 pointer-events:none;
 /* 这个属性设置为none,让所有事件穿透过去 */
 z-index: 100;
 width: 100%;
 height: 100%;
 position: fixed;
 top: 0;
 left: 0;
 right: 0;
 bottom: 0;
}
.movable-view{ 
 pointer-events:auto;
 /* 重设为auto,覆盖父属性设置 */
 height: 100rpx;
 width: 120rpx;
 /* background: red; */
}

当然自己也可以写移动位置，但是人家写出啦就直接用，不过还是自己去写比较好哟，taro小程序悬浮按钮移动参考：

用taro组件写的如下：

 <MovableArea className='customPage-MovableArea'>
        <MovableView
          direction='vertical'
          y={windowData.safeArea.height-300}
          x={windowData.safeArea.width-30}
          className='customPage-MovableView'
        >
          <View className={`home-service ${isChooseMore ? 'active' : ''}`}>
            {
              isChooseMore ?
                <View className='home-service-choose'>
                  <View className='choose-wechat' onClick={this.copyWechat.bind(this)}>
                    <View className='choose-call-logo'></View>
                客服微信
              </View>
                  <Button openType='contact' hoverClass='none' className='choose-call'>
                    <View className='choose-call-logo'></View>
                   客服聊天
                </Button>
                  <View className='choose-phone' onClick={this.callPhone.bind(this)}>
                    <View className='choose-call-logo'></View>
                客服电话
              </View>
                  <View className='choose-hide' onClick={this.setChooseState.bind(this, false)}></View>
                </View> :
                <View className='home-service-pic' onClick={this.setChooseState.bind(this, true)} ></View>
            }
          </View>
        </MovableView>
      </MovableArea>

样式如下：

.customPage-MovableArea {
