jquery ajax combined with thinkphp's getjson to achieve cross-domain method

The example of this article describes the method of combining jquery ajax with thinkphp's getjson to achieve cross-domain. Share it with everyone for your reference, the details are as follows:

The post in jquery should not be cross-domain. It is said on the Internet that the get can be cross-domain, but I tried it but it didn’t work, and then I made the final effort to getjson. The result was successful, haha

js writing:

$.getJSON(
    "/index.php/Index/test",
    function(data){
    alert(data.dd);
    }
);

Syntax:

jQuery.getJSON(url,[data],[callback])

Writing at php:

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

This way you can access across domains.

If it still doesn’t work, it prompts a problem with the same origin policy, then on the server side, in the php file, write

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

means Supports access from all other domains. If it is a designated domain access, change the * number to the domain name, such as:

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

I hope this article will help everyone jQuery program Design helps.
