javascript - 大家一起看看这段js代码，有引用skrollr.js，到底做了哪些事情？

Question

一段代码

js
skrollr.js

Answer 1

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
