title: jquery: getting any change event on any form
body: <p>I know I can get any change event on one form by using this code: </p>
  
  <pre><code>$("#testForm :input").change(function() {
  console.log($(this).attr('name'));      
  });
  </code></pre>
  
  <p>How would I get it if I have multiple forms?</p>
