Fetch meta-tags from url only by jQuery

Question

Now a lot of scripts to facebook-style fetching data from url, but all of them work only in combination of jQuery and PHP. Is it possible to fetch url only by jQuery?

I have found here how to get mata-tags of page by:

$('meta[name=description]').attr("content");
$("meta[property=og:title]").attr("content", document.title);

But how correctly insert this query in jQuery.get() to get text values?

$.get('http://www.imdb.com/title/tt1375666/', function(data) {
  $('meta[name=adescription]').attr("content");
});

And if the most popular sites use OpenGraph should I look in the direction of jQuery.getJSON()?

Answer 1

It seems like this wouldn't be possible because of the Cross Origin Policy

There are definitely ways of doing it with combination client & server side changes. Instead I've been using this API in a project that works well as a simple REST API to get a url's open graph data. GET https://opengraph.io/api/1.0/site/<URL encoded site URL> https://opengraph.io/

It's been working for me as a client-side javascript only solution.
