title: Enable a textarea only if a radio button is selected
body: <p>I have a feedback system in this website I'm building and users are asked to provide feedback for the service they've received. They have a choice to either provide an actual feedback or skip the entire thing. I have 2 radio buttons (1 for positive; the other negative)</p>
  
  <pre><code>&lt;input type="radio" name="rating" value="1" id="green" /&gt;&lt;label for="green"&gt;Positive&lt;/label&gt;&lt;br /&gt;
  &lt;input type="radio" name="rating" value="0" id="red" /&gt;&lt;label for="red"&gt;Negative&lt;/label&gt;
  </code></pre>
  
  <p>Then, I have a <code>textarea</code> for users to provide the actual feedback.</p>
  
  <pre><code>&lt;textarea style="width: 95%;" rows="6" name="feedback"&gt;&lt;/textarea&gt;
  </code></pre>
  
  <p>I'd rather have the textarea enabled <strong>ONLY</strong> if the user clicks on an actual radio button. If not, the textarea remains disabled. How should I go about this? (I'm thinking jQuery)</p>
  
  <p>Thanks, guys.</p>
  
  <p>[EDIT]</p>
  
  <p>Thanks for the quick input, guys. Also, if I may add, what if let's say I'm generating the rows from data in MySQL. Which makes the names (ie. for userid 1) name=rating[1] and name=feedback[1]. How do I select them using jQuery?</p>
