title: get json data from external url with jquery
body: <p>I have a simple 2 fields external json url.</p>
  
  <p>it has 2 fields: identifier and description</p>
  
  <p>Here is the code I'm trying to use to get the description from it:</p>
  
  <pre><code>jQuery("#get_json").click(function(event){
     jQuery.getJSON('http://ec.europa.eu/research/participants/portal/data/call/topics/einfra-11-2016.json?callback=?', function(jd) {
        alert(jd.description);
     });
  });
  </code></pre>
  
  <p>But it gives me an error in the browser console: <code>SyntaxError: Unexpected token ':'. Parse error.</code></p>
  
  <p>Can someone please give me a hint what I'm doing wrong? Thank you</p>
