How can i set a time that a person can vote again?

Question

i have a voting system that you dont have to login to and i want to know how i can set it to where they can vote once per day, either by blocking IP or something of the sort. i prefer not to have a database

<script type="text/javascript">

var clicks = 0;
function linkClick(){
document.getElementById('clicked').value = ++clicks;
}

document.write('<a href="#" onclick="linkClick()">Vote Now!</a>');

$('#clicked').parent().bind('click', function(evt) {
$(this).unbind('click');   
/* do long time task....

evt.preventDefault();
});


</script>

You have clicked the link <input id="clicked" size="3" onfocus="this.blur();" value="0" > times

this code as it stands will only let a use vote once and only once, i would like it to be every 24 hours and in html, thank you in advance

Answer 1

You could create a cookie and check that each day to see if they have voted already. Although JCO611 is correct, this is easily bypassed. I would recommend using some server side code.
