Question

I’m sure there is a simple explanation to this. I am having problems understanding why the following alert does not display in my javascript:

<script>
   theURL = "gb.json?callback=?";
   $.getJSON(theURL, null, function(data) {
      alert('in json proc');
   });
</script>

the file gb.json is in the same folder as the html containing the script. When I run it in Firebug it gets a return code of 200 OK and I see the contents of gb.json.

This must be something very simple that I’m missing. The alert should display, shouldn’t it?

Answer 1

It seems your server is returning regular JSON, not JSONP. Just pass the URL directly, without the added callback query string:

$.getJSON('gb.json', function(data) {
    alert('in json proc');
});
