title: this.getElementById is not a function
body: <p><a href="https://jsfiddle.net/r3kfjx6a/" rel="nofollow noreferrer">https://jsfiddle.net/r3kfjx6a/</a></p>
  
  <pre><code>let myForm = document.getElementById('myForm')
  
  myForm.addEventListener('submit', function(e){
    e.preventDefault()  
    console.log( this.getElementById('email') )
  })
  
  &lt;form id="myForm"&gt;
    &lt;input type="email" id="email" placeholder="email"&gt;
    &lt;button type="submit"&gt;Send&lt;/button&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>Why I can't start from <code>this</code> to query inside the form? </p>
