小程序齐层看板 scrollview 解决抖动

        

　　  这个图分解成4块 上左：楼层    上右：基础数据  下左：固定文字  下右：楼栋

　　  楼层可上下滑动

　　  楼栋可左右滑动

         基础信息可上下左右滑动

         楼层scroll-view 与基础信息scroll-view 上下滑动关联

     　楼栋scroll-view 与基础信息scroll-view 左右滑动关联

　　 当同时滑动  楼层与基础信息 并且滑动方向相反就会导致scroll事件的监听进入死循环导致页面抖动

　　为了解决这个问题就设想同时只能滑动一个scroll-view

       就写了三个遮罩层在三个scroll-view上

       当 一个scroll-view 触发了 touchstart 事件其他两个scroll-view 上面的遮罩层显示

 　  当 scroll-view 触发了 touchend 事件三个scroll-view 上面的遮罩层隐藏

       这样就解决了同时触发两个@scroll事件进入死循环
