title: Set focus on input field with jquery in specific table row
body: <p>I have following html:</p>
  
  <pre><code>&lt;table&gt;
    ....
    &lt;tr&gt;
      ....
    &lt;/tr&gt; 
    ....
    &lt;tr id="myid"&gt;
       &lt;....&gt;
          &lt;input value="..." /&gt;
       &lt;/....&gt;
    &lt;/tr&gt;
    &lt;tr id="myanotherid"&gt;
       &lt;....&gt;
          &lt;input value="..." /&gt;
       &lt;/....&gt;
    &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>How can I set the focus on this input field in table row "myid" with jquery ? I can't set id on input field, because this html was generated automatically.</p>
