title: Set the value of element by classname, without having the element's ID
body: <p>Assume that we have the following code:</p>
  
  <pre><code>&lt;span class="input-text"&gt;
      &lt;input type="search"&gt;
  &lt;/span&gt;
  </code></pre>
  
  <p>Is there any way, we could set the <code>value</code> of that without having the <strong>ID</strong> of the <em>element</em>?</p>
