title: Loader on PHP form submit
body: <p>I'm trying to establish a 'Loader' upon user submitting the form (PHP). Here's what I've got so far which doesn't seems to be working.</p>
  
  <p>Can you please highlight where could be the potential issue?</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html lang="en"&gt;
  &lt;head&gt;
      &lt;meta charset="UTF-8"&gt;
      &lt;title&gt;Document&lt;/title&gt;
      &lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"&gt;&lt;/script&gt;
  
      &lt;script type="text/javascript"&gt;
       $('#myForm').submit(function() {
         $('#loaderImg').show(); 
         return true;
       });
      &lt;/script&gt;
  &lt;/head&gt;
  
  &lt;body&gt;
  &lt;div class="wrapper"&gt;
      &lt;form action="" method="post" id="myForm" name="myForm"&gt;
          &lt;img src="../images/loader.gif" alt="loader1" style="display:none; height:30px; width:auto;" id="loaderImg"&gt;
          &lt;input type="submit" id="clicknow" value="Click the button to go to another page"&gt;
      &lt;/form&gt;
  
  &lt;/div&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
