uniapp movable-area、movable-view实现上下滑动

效果图：

 

 <movable-area class="move-content" @touchmove.stop>
      <movable-view
        class="move-incontent"
        :style="'height:' + movableHeight + 'rpx'"
        :y="initY"
        inertia
        :damping="20"
        :friction="1"
        direction="vertical"
        :animation="true"
        @change="movableChange"
        @touchend="touchEnd"
      >
        <slot></slot>  
      </movable-view>
    </movable-area>

data(){
return{
　　　movableHeight: 1000,
     windowHeight: 0,
     initY: 0,
     dragY: 0
}
},
onLoad() {
    this.windowHeight = uni.getSystemInfoSync().windowHeight;
    this.movableHeight = (this.windowHeight) * 2;
        },
methods:{
　　movableChange(e) {
      let y = e.detail.y;
      this.dragY = y;
    },
            //触摸结束
    touchEnd(e) {
      this.initY = this.dragY; //这行必写 不然无法自动滑动到顶部或者底部
    }
}
