使用 jquery scrollify 更改固定 div 的 Div 内容

Changing Div content of fixed div using jquery scrollify

我有一个固定的DIV和3个部分A、B、C

我正在使用 jquery scrollify 来更改部分的数据,我想更改特定的 div 滚动鼠标滚轮的数据。

如您所知,scrollify 允许我们滚动鼠标滚轮旋转的部分,当部分更改时我需要更新固定的 div 数据和 相应的部分内容

部分高度和宽度将为 屏幕高度屏幕宽度

我用 using scrollify website example 问了几乎 same question 但我没有得到任何回应,所以我决定用图形示例再次询问

这是视差你需要做的就是看这个例子
