How to Do htis Voting Mechanism

[om20]

There is a "voting type mechanism" on www.fmylife.com . Where you can simply press and add your vote, without having to log in. can someone help me find the code for this? I;m rather new

[Asperon]

<a href="#" onclick="addVote(); return false;">Vote!</a>

<script type="text/javascript>
function addVote(){

    // Run ajax function here that changes a database value for the number of votes

}
</script>

Some like this perhaps would work, depends on what you need.
