title: If a <td> contains "a" then make the <tr> background red but the each() is to slow
body: <p>How do you write this so it runs faster. It looks like because I'm using an each() it is slowing it down.  </p>
  
  <p>Can I use filter()?</p>
  
  <pre><code> $("#X tr").each(function () {       
       if ($(this).find("table td:eq(1)").text() == "a") {
           $(this).css("background":"red");    
    }
  
  });   
  
       &lt;table id = "X"&gt;
          &lt;tr &gt;
          &lt;td&gt;a&lt;/td&gt;
          &lt;td&gt;b&lt;/td&gt;
          &lt;td&gt;c&lt;/td&gt;
          &lt;/tr&gt;
          &lt;tr &gt;
          &lt;td&gt;&lt;/td&gt;
          &lt;td&gt;&lt;/td&gt;
          &lt;td&gt;&lt;/td&gt;
          &lt;/tr&gt;
          ...
          &lt;tr &gt;
          &lt;td&gt;a&lt;/td&gt;
          &lt;td&gt;b&lt;/td&gt;
          &lt;td&gt;c&lt;/td&gt;
          &lt;/tr&gt;
     &lt;/table&gt;
  </code></pre>
  
  <p>thanks</p>
