Indeed, this is a distinctly AJAX feature, most of the code being on the server side.

The code your posted is very easy to hack... you put the score in the Javascript lol? Someone could just put 10000 in the javascript and have a boost of vote :P

Daok, my code isn't for production. Of course it's not secure. It's meant to convey an idea, not a full solution.

On the server side you would limit scores to "1" or "-1", and your attempt to send 1,000 across will fail.

much as this looks like it will work, you're using a GET request to change data on the server. The arguments are varied, but strictly I think you should use $.post here

As with all things, server-side validation would be a must. Note that he *did* say "do not use as-is".

@David, I went with GET for a fall-back incase scripting isn't available. It work work either way.

fair play, sir :-) I wasn't really trying to 'down' you. Just pointing out so the asker can be aware for future reference.

@David - No worries. I didn't feel like you were "downing" me :)

If I am blocking the user to vote only once on the basis of IP address (for gust users) and userid (for registered users), which means one person can vote one time up or down, user also has the option that he can later change there vote, means if i have voted up then after sometime i can vote it down also, so my up vote will be removed and down vote will be counted. Is there any security measures in this scenario ?

Prashant, As long as you check to see if the user has already voted, you should be safe. If they voted, and their previous vote is different than the one they're now sending, then update their record. If they haven't voted, insert a new record. If they've voted, and it's the same value, bake them a cake :) Just be sure to always check for previous activity.
