title: Redirect based on user input
body: <p>I have 20 different pages. Let's say that IDs of the pages are for example: <code>mysite.com/page1</code>, <code>mysite.com/page2</code> and so on...</p>
  
  <p>I need to create an input field where the user can enter numbers, and if he inputs number 16 for example, it will redirect him to <code>mysite.com/page16</code>.</p>
  
  <p>I believe that this is possible with JavaScript. Has anyone got any advice?</p>
