title: How do I trigger Form Submission in Javascript?
body: <p>I have initialized my form submission like following:</p>
  
  <pre><code>$(document).ready(function() {
     $("#my_form").submit(function(e) {
           ...
           ...
     }
  }
  </code></pre>
  
  <p>As you see above, it is in <code>$(document).ready(...)</code>. When user press "Submit" button on UI, the form will be submitted. </p>
  
  <p>But, How can I also trigger this form submission in Javascript besides user input (e.g. press submit button on UI)?  </p>
