title: Select element by exact match of its content
body: <p>All right, I wonder if there is a way to make the <code>:contains()</code> jQuery's selector to select elements with <strong>only</strong> the string that is typed in</p>
  
  <p>for example -<br /></p>
  
  <pre><code>&lt;p&gt;hello&lt;/p&gt;
  &lt;p&gt;hello world&lt;/p&gt;
  
  $('p:contains("hello")').css('font-weight', 'bold');
  </code></pre>
  
  <p>The selector will select both <code>p</code> elements and make them bold, but I want it to select only the first one.</p>
