你去查上下文 data.curTop 和 data.lastTop 的取值然后官方文档里有描述A listener function that gets called each time right before we render everything. The function will be passed an object with the following properties:{ curTop: 10, //the current scroll top offset
lastTop: 0, //the top value of last time
maxTop: 100, //the max value you can scroll to. curTop/maxTop will give you the current progress.
direction: 'down' //either up or down}Returning false will prevent rendering.当返回 false 停止渲染
