两个SVG元素触摸时的事件 [英] Event when two SVG elements touch

问题描述

使用任何方法在SVG中是否可以调用即使两个特定元素接触？或者我要编码很长的路要走，弄清楚他们的边界是否接触到复杂的数学？

Is it possible in SVG, using any method, to call an even if two specific elements touch? Or would I have to code the long way, and figure out if their borders touch with complicated maths?

推荐答案

在SVG 1.1 DOM中用于交叉点处理的最外层SVG元素上可用的方法：

There are actually four methods available on the outermost SVG element for intersection handling in the SVG 1.1 DOM:

1. getIntersectionList


2. getEnclosureList


3. checkIntersection


4. checkEnclosure

1. getIntersectionList
2. getEnclosureList
3. checkIntersection
4. checkEnclosure

不幸的是，我认为跨浏览器支持这些方法是直到不好。

Unfortunately I think the cross-browser support for these methods is still not great.
