This works:
<script language="Javascript">
function checkForm(myform) {
if(myform.comments.value.match(/^\s*$/)) {
// it's empty
alert('You must enter a value for comments');
return false;
}
else {
return true;
}
}
</script>
<cfform action="action.cfm" name="a">
<textarea name="comments" cols="50" rows="12"></textarea>
<input type="image" src="images/submit.gif" value="Submit Form"
onClick="return checkForm(this.form);" />
</cfform>
