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

The example in this article describes the method of using jquery ajax combined with thinkphp's getjson to achieve cross-domain. I share it with you for your reference. The details are as follows:

Post in jquery should not be cross-domain. It is said on the Internet that get can be cross-domain, but I tried it but it didn’t work. Then I tried my best to getjson and the result was successful, haha

JS writing:

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

Syntax:

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

PHP writing:

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

This way it can be cross-domain Visited.

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 to support access from all other domains. If it is a specified domain access, put * Change the number to a domain name, such as:

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

I hope this article will be helpful to everyone in jQuery programming.
