$.ajax(): Origin null is not allowed

Tags:

ajax

I'm just starting with $.ajax(). This is my code:

<html>
<head>
    <title>Commons app</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
</head>
<body>
<script type='text/javascript'>
    if($) console.log('jQuery loaded!\n');

    $(function () {
        $.ajax({
            url: 'http://en.wikipedia.org/w/api.php?action=query&list=allimages&ailimit=5&aifrom=Albert&aiprop=dimensions|mime&format=jsonfm&callback=?'
        })
        .done(function () { console.log('Yay!'); })
        .fail(function () { console.log('Error!'); })
        .always(function () { console.log('Complete!'); });
});
</script>
</body>
</html>

For some reason I get the following error message:

XMLHttpRequest cannot load http://commons.wikimedia.org/w/api.php?action=query&generator=allimages&gailimit=4&gaifrom=T&prop=imageinfo&iiprop=url&callback=?. Origin null is not allowed by Access-Control-Allow-Origin.

Update: This method is deprecated from jQuery 1.9. Does not work anymore.

Old answer:

Try this (updated):

$.support.cors = true;

$(function () {
     $.ajax("http://commons.wikimedia.org/w/api.php?action=query&generator=allimages&gailimit=4&gaifrom=T&prop=imageinfo&iiprop=url&callback=?")
     .complete(function () { alert('complete'); })
     .error(function () { alert('error'); })
     .success(function (data) { alert(data); });
});

More about jQuery.support.cors setting here: jQuery.support

P.S. thanks for a nice question! I believe it will be useful for me also in future.
