title: Temporarily disable all events
body: <p>Let's say I have this part of javascript code :</p>
  
  <pre><code>$('a').on('mouseenter', function() {console.log('you just hovered a link')});
  </code></pre>
  
  <p>And that sometimes, I want to disable all events because the page is for example, loading. I can achieve this via :</p>
  
  <pre><code>$(*).off();
  </code></pre>
  
  <p>However, how can i re-enable all events when page finished loading ?</p>
