I have two radio button on HTML page. Each radio button has a name.
The first radio button is "No" and the second radio button is "Yes"

I have a text area on page. I want to lock text area if User select NO button, and allow text area if user select "Yes" radio button.

Is hard to do this ? Anyone help me with some idea?

Moved to Javascript.

EDIT:

Something like that?

Code:

<script type="text/javascript">

function enable_area(opt)
{
	document.form.textarea.disabled = (opt == 'yes' ? false : true);
}

</script>

<form action="" method="post" name="form">
Yes <input type="radio" name="radio" value="yes" onclick="enable_area(this.value);" />
No <input type="radio" name="radio" value="no" onclick="enable_area(this.value);" />
<br />
<textarea name="textarea"></textarea>
</form>
