title: Input .value returns undefined
body: <p>The value of the input entered is returned as <code>undefined</code>. I already saw other questions like this, but nothing worked. Anyway, when I use my jQuery it always gives me <code>undefined</code>. </p>
  
  <p>jQuery:
  <div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>$( document ).ready(function() {
  $('#Input').keypress(
      function(e){
          if (e.keyCode == 13) {
              alert( "&gt;" + $("#Input").value );
          }
      });
  }); </code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt;

  &lt;style type="text/css"&gt;
  body{

  input{

   float: left;
   margin-left: 10px;
   list-style-type: none;
   position: absolute; 
   bottom: 17px;
  }
  
  input:focus {
      outline: 0;
  }
  h1{
   text-align: center;
   font-size: 50px;

  h2{

  ::-webkit-input-placeholder {

  &lt;h2&gt;&gt;Welcome to Fun Time&lt;/h2&gt;
  &lt;h2&gt;&gt;Press F11 to enter full screen&lt;/h2&gt;
  
  &lt;/div&gt;
  
  &lt;h3 style="float:left;list-style-type: none; position: absolute; bottom: 5px;"&gt;&gt;&lt;/h3&gt; 
  
  &lt;input name="Input" id="Input" type="text" autofocus&gt; &lt;/input&gt;
  &lt;/body&gt;
  &lt;/html&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>When I alert, <code>undefined</code>. Console log, <code>undefined</code>. Append, gives back an error(the error is irrelevant). I tried changing up the code many times. </p>
