title: How can I handle events with dynamic ID in javascript?
body: <p>I have used dynamic id for the elements of the table. I would like to handle it in javascript. How can I do this? </p>
  
  <pre><code>&lt;table&gt;
      &lt;%@task.each do |task|%&gt;
          &lt;tr id="task-&lt;%=task.id%&gt;"&gt;
              ....
          &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>Now in Javascript, how to get the id of the particular row to handle events like <code>onclick()</code> or <code>onchange()</code>?</p>
