Encouraging people to explain down-votes
Recently I posted an answer to a question. Somebody downvoted it (without leaving a comment). But the solution is working. I have even provided a link to a working demo. How can we stop such kind of downvoting? If someone has done it, how can we recover it? I think by providing a working demo's link I have proven my solution's correctness.
An example of such a downvote is at How to get the ID of a div when using bind() in jQuery?
