Something like:
<textarea name="comments" cols="50" rows="12"></textarea>
Then in the submit button (note it's actually a type="button" not "submit"
as that is done in the JS):
<input type="button" value="Submit Form" onClick="checkForm(this.form);" />
Then in the JS:
<script language="Javascript">
function checkForm(myform) {
if(myform.comments.value.match(/^\s*$/)) {
// it's empty
alert('You must enter a value for comments');
}
else {
myform.submit();
}
}
</script>
NOT tested for cross-browser compatibility (but from what I recall, there
isn't anything in there that isn't pretty generic anyway).
