  <pre><code>&lt;p&gt;Variable Text&lt;/p&gt;
  </code></pre>
  
  <p>And I want to it to be;</p>
  
  <pre><code>&lt;p&gt;Variable &lt;span&gt;Text&lt;/span&gt;&lt;/p&gt;
  </code></pre>
  
  <p>Is this possible by a javascript function? / or jQuery.</p>
  
  <p>Oh yeah, and the p-element got an ID and the text inside the p-element is variable but always consists of 2 words. I want a span around the last word of the text by a javascript function.</p>
