How to pick the title of a remote webpage [duplicate]

Answer 1

You won't be able to get this data with jQuery alone, however you can use jQuery to communicate with PHP, or some other server-side language that can do the heavy lifting for you. For instance, suppose we have the following in a PHP script on our server:

loadHTML( file_get_contents( $_POST["url"] ) );
        $xpt = new DOMXPath( $doc );
        $output = $xpt->query("//title")->item(0)->nodeValue;
    } else {
        $output = "URL not provided";
    }

    echo $output;

?>

With this, we could have the following jQuery:

$.post("getTitle.php", { url:'http://example.com' }, function( data ) {
    alert(data);
});
