I have this JS
http://jsfiddle.net/xzf0ffcu/18/
jsPlumb.ready(function() {
How can I find out whitch element is connected with whitch, can I console.log something like #div1 connected with #div4, #div2 with #div5?
Where you have your console.log() in your jsfiddle.
Replace it with:
console.log("connection", i.sourceId , i.targetId);
