Why isn’t the callback function called in IE?

  1. A call to Flickr:

    $.getJSON("http://api.flickr.com/services/rest/?method=flickr.photosets.getPhotos",
{
    api_key: APIKey,    
    photoset_id: photoSetID,
    format: "json",
    per_page: 40,
    nojsoncallback: 1           
}, displayImages);

function displayImages(data) { alert('called'); }

  2. A call to YouTube:

    $.getJSON('https://gdata.youtube.com/feeds/api/users/username/favorites?alt=json', function(data)
{
    alert('called');
})

Both of these types of calls work on any other browser, except IE.
Can you please explain me why?

    jQuery only supports cross-domain ajax in non-IE<=9 browsers. To use those APIs in IE, you need to use JSONp if available or add a jQuery plugin that adds support for the XDomainRequest api used by IE.

    If possible use JSONp; XDR has quite some limitations – see http://blogs.msdn.com/b/ieinternals/archive/2010/05/13/xdomainrequest-restrictions-limitations-and-workarounds.aspx for details.
