jquery Ajax combines thinkphp Getjson to implement Cross-domain methods _jquery

This article illustrates a cross-domain approach to the Getjson implementation of jquery Ajax combined with thinkphp. Share to everyone for your reference, specific as follows:

jquery in the post should not be cross-domain, the net said get can cross the domain, but I tried not to, and then on the final struggle Getjson, the results of success, haha

JS Office writing:

$.getjson (
    "/index.php/index/test",
    function (data) {
    alert (DATA.DD);
    }
);

Grammar:

Jquery.getjson (Url,[data],[callback])

Parameters	Description
Url	The URL address of the page to be loaded.
Data	The Key/value parameter to be sent.
Callback	The callback function that is executed when the load succeeds.

Writing at PHP:

$data [' dd ']= ' zonglonglong ';
$this->ajaxreturn ($data, ' JSON ');

This allows for cross-domain access.

If still not, hint homologous strategy problem, then in the server, PHP file, then write

Header ("access-control-allow-origin:*");

It means to support access to all other domains, and if you specify domain access, change the * number to a domain name, such as:

Header ("access-control-allow-origin:www.baidu.com");
