How to use ajax to across domain?

Question

I post my code here.(I add the jquery into my web page)

var dataString ='username='+ username + '&password=' + password; //alert (dataString);return false; $.ajax({ type: "POST", url: "http://hisencha.sinaapp.com/login.php", data: dataString, success: function(data) { if(data=='success'){ window.location.href='list.html'; } else{ alert(data); }; } });

above is part of javascript

here is php(demo)

<?php if ($_POST['username']=='aaa' && $_POST['password']=='aaa') { echo 'success'; } else { echo 'error'; } ?>

What can I do now?And how to fix the error about acrossing domain.

Thank you thank you!

Yeah, you can use JSONP to do it. Here's some sample jQuery:

 $.ajax({ type: "POST", url: "http://hisencha.sinaapp.com/login.php?callback=?", data: dataString, dataType: 'JSONP', success: function(data) { if(data=='success'){ window.location.href='list.html'; } else{ alert(data); }; } });

And PHP:

<?php $response = array( 'something' => 'something' ); echo $_GET[['callback'].'('.json_encode($response).')'; ?>

This answer helped me.Thank you very much.It made me know php more!

There's no way to use ajax across domains. It's blocked for security reasons.

There are ways if the other domain simply sets a header to allow it...developer.mozilla.org/En/HTTP_access_control

There are many example to do it, with AJAX-CROSS-DOMAIN or Proxy Handle.
