Callback function not working when using getJSON

This is the code that I use when I write a link in a browser (IE or Mozilla), it works as a (MyFunc ({ "memes": [{ "-source": " http: //www.knall ..... . ), but when I try to run it as an HTML file, I have an error in the status bar.what is the problem ?. Thanks

<head>
  <style>img{ height: 100px; float: left; }</style>
  <script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
    <div id="images"></div>
<script>$.getJSON("http://tagthe.net/api/?url=http://www.knallgrau.at/en&view=json&callback=MyFunc",function(data){         
               alert(data);
        });
</script>
</body>

You don't define MyFunc anywhere in your code. You would rather put ?

in the URL instead of an arbitrary name, and jQuery will replace it with the generated callback name.

Eureka! It doesn't work with the latest version ... you must be using jquery 1.3.1 not newer ...

You should use getScript

instead getJSON

as you are calling the url of a different domain name.

Update:

The following code works fine for me:

<head>
  <style>img{ height: 100px; float: left; }</style>
  <script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
    <div id="images"></div>
    <script>
        function MyFunc(data) {
            alert(data)
        }
        $.getScript("http://tagthe.net/api/?url=http://www.knallgrau.at/en&view=json&callback=MyFunc");
</script>
</body>

you cannot make ajax calls on other domains

http://en.wikipedia.org/wiki/Same_origin_policy

Also, your url is not a valid url, copy and paste it into the browser and you will see the error http://tagthe.net/api/url=http://www.knallgrau.at/en&view = json & callback = MyFunc

valid url: http://tagthe.net/api/?url=http://www.knallgrau.at/en&view=json&callback=MyFunc

$.getJSON("
    http://tagthe.net/api/url=http://www.knallgrau.at/en&view=json&callback=MyFunc",
    function(data){         
        alert(data);
    });
