1、项目开发需要去查看页面上的四幅图片，而且需要同时查看这些图片的相同的相对位置来进行比对，因此想实现滚动图片1的滚动条时，图片2伴随一起运动。
2、

3、图片效果如图，如何实现呢？

监听所有图片容器 p 的 onscroll 事件
修改其他 p 的 scrollTop 为当前事件触发元素的 scrollTop

那个，没做过类似的项目，找了一个方法，获取滚动距离的，你可以用js来动态修改图2 的滚动距离：
function ___getPageScroll() {
var xScroll, yScroll;
if (self.pageYOffset) {

yScroll = self.pageYOffset;
xScroll = self.pageXOffset;

} else if (document.documentElement && document.documentElement.scrollTop) { // Explorer 6 Strict

yScroll = document.documentElement.scrollTop;
xScroll = document.documentElement.scrollLeft;

} else if (document.body) {// all other Explorers

yScroll = document.body.scrollTop;
xScroll = document.body.scrollLeft;

}
arrayPageScroll = new Array(xScroll,yScroll);
return arrayPageScroll;
};
