Help! Ajax not getting an external page content?

I want to extract the source code of a webpage which is hosted by other website, but the problem is that O get an empty response, I tried to pull the source of multiple websites but the problem is from my code:

$(document).ready(function(){
    $.get('http://www.xxxx.com', function(xdata) {
        alert("content: "+xdata);
    });
});

Is there any mistake?

Note: when I try to get the source of a local page, it works, but I don't know why it doesn't for an external one

Thanks

I have a server using a virtual domain and created an apache proxy.

Super fast, works, no quirks.

Copy this, fix paths (mod_proxy, domains, etc...), add to your .conf file, restart server

LoadModule proxy_module /usr/local/zend/apache2/modules/mod_proxy.so
LoadModule proxy_http_module /usr/local/zend/apache2/modules/mod_proxy_http.so
ProxyRequests Off
ProxyPreserveHost On 
ProxyPass /datadomain http://datadomain.com/webservices
ProxyPassReverse /datadomain http://datadomain.com/webservices

Now http://datadomain.com/webservices/data.php = http://yourdomain.com/datadomain/data.php

Enjoy!!!

If you're not interested in building your own proxy, there's a very easy-to-use public proxy (hosted on AppEngine) for this, with a JavaScript library. CurlJS: http://curljs.azoffdesign.com/

Your example could be done like this (after including the library):

curl("http://www.xxxx.com", function (status, xdata) {
  alert("content:" + xdata);
});

Hope that helps!

Because of the SOP (same origin policy), You can't use URL's from other domains. Try accessing a page from local server and don't use http.

Access-Control-Allow-Origin: * header need to set on external site to do cross domain access.

You cannot use contain from an other domain because of the same origin policy

please look into JsonP.

This isn't allowed, according to the Same Origin Policy.

The only way to approach this is to use some server-side pull of the data, which you would then process using your AJAX requests, this is known as a Cross-Domain Proxy.
