title: how to enter a random value in a textarea without an id?
body: <p>I have to enter a random value in a <code>textarea</code> of a web site by using grease monkey script the text area didn't have an <code>id</code> so <code>document.getElementById</code> doesn't work.</p>
  
  <p>Can I use another method to do that?</p>
  
  <p>My current HTML showing my <code>textarea</code>:</p>
  
  <pre><code>&lt;tr&gt;
      &lt;td class="tdv pd5"&gt;&lt;span class="tbg"&gt;
          Message&lt;/span&gt;&amp;nbsp;&lt;/span&gt;
      &lt;/td&gt;
      &lt;td class="pd5"&gt;
          &lt;textarea name="inpx_msg" class="msgbox"&gt;&lt;/textarea&gt;
          &lt;br /&gt;
          &lt;div class="tsm"&gt;140 characters max.&lt;/div&gt;
      &lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
