It seems that the server does not allow a cross domain request. Nothing you can do.
You can set up a PHP script that can curl that page and then you can just ajax the PHP script. Like what kuncajs said
You can use this short PHP curl script on your server:
<?php
$ch = curl_init();
// URL to grab
curl_setopt($ch, CURLOPT_URL, 'http://jquery-ui.googlecode.com/svn/tags/1.8.23/themes/');
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);
print_r($output);
?>
Then it is just a simple ajax script:
$.ajax({
url: "linktoscript.php",
dataType: "html",
success: function(data) {
console.log(data);
},
error: function (request, status, error) {
console.log(request);
console.log(status);
console.log(error);
}
});
