title: jquery trigger hover on anchor
body: <p>I'm using jQuery to develop in web environment.</p>
  
  <p>I want to know why </p>
  
  <pre><code> $("#a#trigger").trigger('mouseenter');
   $("#a#trigger").trigger('hover');
   $("#a#trigger").trigger('mouseover');
  </code></pre>
  
  <p>All 3 of those aren't working to activate a hover function that I have.</p>
  
  <pre><code>$(function() {
  
  
          $('a#trigger').hover(function(e) {
            $('div#pop-up').show();
  
               }, function() {
            $('div#pop-up').hide();
          });
  
       });
  
        });
  </code></pre>
  
  <p><code>a#trigger</code> is the name of the anchor, and <code>#pop-up</code> is a div element in my web.</p>
  
  <p>The problem is that I want to mouse over some event in FullCalendar plugin and those functions aren't working.
  Thanks. </p>
