You can use the onClick
event to do that:
Working Example
HTML:
<button id="some_id">Hide div</button>
<form id="some_form">
<form>
javascript:
<script type="text/javascript">
var theButton = document.getElementById('some_id');
theButton.onclick = function() {
document.getElementById('some_form').style.visibility='hidden';
}
</script>
