I have a contact form on my website that emails me info from interested parties. I don't want to use a captcha for various reasons. I just want to do something simple, like disable the submit button on the form until the user answers a simple question. Hopefully this will keep out some bots at least. I found this on the web but it does absolutely nothing:
<script>
document.getElementById("Submit").disabled=true;
</script>
Can someone either correct this or give me something better?
