title: Upgrade from jQuery 1.x to jQuery 2.x
body: <p>I am trying to upgrade from jQuery 1.x to jQuery 2.x. </p>
  
  <p>I have jQuery 1.8 and jQueryUI 1.8, and now I want to upgrade to jQuery 2.x and enhance my web app.  </p>
  
  <p>So my question is what to change and remove, like for <strong>Ajax</strong> and <strong>events</strong>.</p>
  
  <p>Like these errors I am talking about </p>
  
  <pre><code>Uncaught TypeError: Object [object Object] has no method 'live'
  </code></pre>
  
  <p>Did functions like .on() and .ajax() change any? (I know .live was deprecated).</p>
  
  <p>P.S. I have to add Zurb Foundation 5 which uses jQuery 2.</p>
