If you want to minimize the 'impact' on the original document put all the circle in a special group (probably dynamically created) so you can just delete the group to 'reset' the document. This way you can let the SVG engine do all the event tracking. You could add an event listener (mouse move or the like) to the rootmost SVG element and you will get notified of any mouse event over any element in the document. You could then manually check these points against your circles. But this seems like a bunch of extra work for nothing. > > yasmin > > > > Hello, > > For events, I attach an event to the entire document. For > > individual elements, this may work.
