javascript - disable the submit button -

i have contact form on website emails me info interested parties. don't want utilize captcha various reasons. want simple, disable submit button on form until user answers simple question. maintain out bots @ least. found on web absolutely nothing:

<script> document.getelementbyid("submit").disabled=true; </script>

can either right or give me better?

first of create sure if testing code have in onload function such:

window.onload = function(){ document.getelementbyid("submit").disabled=true; }

also create sure id submit , not submit because javascript case-sensitive.
