问题 I'm writing what will be an intranet application, and one of its features is roughly analogous to content voting - not unlike what SO, Amazon, and many other sites do.

Here is what I wrote in the HTML : $("#q_upvote").click(function() { var vote = "vote_up"; var votedata = ""; votedata = "vote= " + vote; $.ajax({ type:
