javascript - Event when two SVG elements touch

Question

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?

Answer 1

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

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