title: binding on change event to group of input fields in jquery
body: <p>I have three input fields as below:</p>
  
  <pre><code> &lt;input type="text" name="address" id="address"/&gt;
   &lt;input type="text" name="city" id="city"/&gt;
   &lt;input type="text" name="country" id="country"/&gt;
  </code></pre>
  
  <p>How can i add onChange event to all of these fields at once something like this:</p>
  
  <pre><code>$("select the elements with id address,city,country").bind("change", function() {
              //do something
          });
  </code></pre>
