title: jQuery: get value of clicked element
body: <p>I have this piece of code:</p>
  
  <pre><code>&lt;tr class="editField"&gt;
    &lt;td&gt;abc&lt;/td&gt;
    &lt;td&gt;123&lt;/td&gt;
    &lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr class="editField"&gt;
    &lt;td&gt;dfg&lt;/td&gt;
    &lt;td&gt;456&lt;/td&gt;
    &lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p>And then I have this javascript to open a dialog with jQuery:</p>
  
  <pre><code>$( ".editField" ).click(function() {
          alert(...); // should get me 123
  });
  </code></pre>
  
  <p>Suppose I click on first <code>tr</code> and I would get the content of second <code>td</code> (i.e 123), what should I write?</p>
