title: Find a table row below to highlight it
body: <p>I got checkbox:</p>
  
  <pre><code>&lt;input class="_checkbox" type="checkbox"/&gt;
  </code></pre>
  
  <p>And , when I click it:</p>
  
  <pre><code>$(function() {
      $('._checkbox').click(function() {
          [..]
      });
  });
  </code></pre>
  
  <p>I need to highlight a table row that is below the checkbox.
  I've tried with :</p>
  
  <pre><code>$(function() {
      $('._checkbox').click(function() {
          $(this).siblings("#table_row").css("background-color", "blue");
      });
  });
  </code></pre>
  
  <p>But doesn't work.</p>
  
  <p>I guess I'll have to add some unique IDs, but have no idea how should I read them , etc.</p>
