title: Text input readonly attribute not recognized in IE7?
body: <p>I am setting readonly="readonly" (in other words, true) via javascript:</p>
  
  <pre><code>document.getElementById("my_id").setAttribute("readonly", "readonly");
  </code></pre>
  
  <p>This is having the intended effect (making the field no longer editable, but its contents are submitted with the form) in FF, Safari and Chrome, but not for IE7. In IE7 I can still modify the contents of the text input field.</p>
  
  <p>I have tried setting ("readonly", "true") as well, which works in all three other browsers that I am testing, but which IE7 also ignores.</p>
  
  <p>Does anyone have experience with trying to do this with IE7? I do not want to use the disabled attribute as I want the value within the text input field to be submitted with the form.</p>
