verifyRequired and vairables

[cjh088]

Hi, im a n00b at javascript. I am trying to create a simple test to make sure the user is human and not a bot.

so what i did was
<script language=javascript>
var check
var check2
check= (Math.random());
check2= (Math.round(check*100000));
document.write(check2);
</script>

I then created a verifyRequired script

<script language=javascript>
function verifyRequired(){
if (document.formcheck.security !=check){
alert("The security key entered is invalid")
return false;
}
return true;
}


My problem is that the verify function does not appear to beable to check the random number generated each time the page loads, any ideas on a possible work around.

Suggest that you try CAPTCHA as a solution -

Hi

Please note that bots usually not execute JavaScript code. Even more, many of them does not request the once visited [tt]form[/tt] again, only submit again and again. ( So if your [tt]form[/tt] is already known by such bots, they will never notice that you modified your page. ) Your "verification" will only annoy humans.

So do as Greg suggested. ( But avoid other JavaScript based messing like Internet Captcha. ) Or try jpadie's solution.
