基于x& D获取DIV id你的位置 [英] Getting DIV id based on x & y position

问题描述

我试图解决的问题是这个位置是什么？

The problem I'm trying to solve is "What's at this position?"

获得DIV的x / y位置（偏移量）是相当简单的，但反过来呢？如何获得给定x / y位置的DIV（或任何元素）的id？

It's fairly trivial to get the x/y position (offset) of a DIV, but what about the reverse? How do I get the id of a DIV (or any element) given an x/y position?

推荐答案

不幸的是，触发a制造/模拟鼠标事件将无法工作，因为当您发送它时，您必须提供目标元素。由于那个元素是你想要弄清楚的元素，你所能做的就是将它分配到身体上，好像它已经冒泡了。

Unfortunately, triggering a manufactured/simulated mouse event won't work, since when you dispatch it, you have to provide a target element. Since that element is the one you're trying to figure out, all you could do is dispatch it on the body, as if it had already bubbled.

你真的是左手自己做，即手动浏览你感兴趣的元素，并将它们的位置/大小/ zIndex与你的x / y点进行比较，看看它们是否重叠。除了IE和更近期的FF3，你可以使用

You really are left to do it on your own, that is manually walk through the elements you're interested in, and compare their position/size/zIndex to your x/y point and see if they overlap. Except in IE and more recently FF3, where you can use

var el = document.elementFromPoint(x, y);
