title: Get the value of a twitter bootstrap radio button. JQuery
body: <p>I'm using the Radio-button from twitter bootstrap: <a href="http://twitter.github.com/bootstrap/javascript.html#buttons" rel="noreferrer">http://twitter.github.com/bootstrap/javascript.html#buttons</a>.</p>
  
  <p>In my html in looks like this:</p>
  
  <pre><code>  &lt;div class="btn-group" data-toggle="buttons-checkbox"&gt;
    &lt;button type="button" class="btn"&gt;Left&lt;/button&gt;
    &lt;button type="button" class="btn"&gt;Middle&lt;/button&gt;
    &lt;button type="button" class="btn"&gt;Right&lt;/button&gt;
    &lt;/div&gt;
    &lt;input type="submit" onclick="get_the_value_and_do_something_with_it"
  </code></pre>
  
  <p>I would like to know how to get the value of the button the user checked thanks to Jquery or Javascript.</p>
  
  <p>I saw several question on this topic, but I think it is different with this kind of button, because it looks like they do not accept a "checked" attribute.</p>
  
  <p>Any help would be very welcome</p>
  
  <p>PS: if someone knows how to check by default one of the button, it would also help me a lot. Thank you.</p>
