title: How can I disable an <option> in a <select> based on its value in JavaScript?
body: <p>I have a <code>&lt;select&gt;</code> with a number of <code>&lt;option&gt;</code>s. Each has a unique <code>value</code>. I need to disable an <code>&lt;option&gt;</code> with a given defined <code>value</code> (not <code>innerHTML</code>).</p>
  <p>Anyone have an idea how?</p>
