仿苹果返回首页按钮(移动端div拖动 返回首页)

Posted

tags:

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了仿苹果返回首页按钮(移动端div拖动 返回首页)相关的知识，希望对你有一定的参考价值。

参考技术A 参考了网上的文章，然后又完善了一下

大概思路：

1、实现页面的拖动效果：首先是明白移动端的touchstart touchmove touchend的用法

2、div移动其实就是它的left 和 top 的移动

3、touchstart 的时候，记录鼠标的坐标和div的偏移量，由此可以计算出鼠标和div左侧和顶部的距离

4、touchmove 的时候，记录新的鼠标坐标，用新的坐标-起点鼠标和偏移量的差值=div需要移动的距离

5、边界值限制，防止div 移出来

6、禁止底层滑动

7、跳转到首页或者百度
