“资源被解释为脚本，但以MIME类型text / html传输”响应

Question

I have an ajax call to a PHP (on a different domain) login-script, which looks as the following:

var request = $.ajax({
        crossDomain: true,
        url: "http://www.domain.com/PHP/fct.login.php",
        type: "POST",
        data: $('#loginForm').serialize(),
        dataType: "jsonp",
        contentType: "application/json; charset=utf-8",
    });

And in my PHP script I have following:

<?php
header('Content-Type: text/javascript');
echo $_GET['callback'] . '(' . "{'status' : '1'}" . "{'text' : 'ok'}" . "{'userid' : $member['user_id']}" . ')';
?>

But it doesn't work. In my console I just get a Resource interpreted as Script but transferred with MIME type text/html message...

EDIT : I updated my response as 'Felix Kling' said, but now I'm getting a parse error.

My updated response looks like:

echo $_GET['callback'] . "({status : 1},{text : 'ok'},{userid : ".$member['user_id']."})";

And the error looks like:

Error: Parse error on line 1:
{status : 1},{text :
-^
Expecting 'STRING', '}'

EDIT 2 : Never mind, it works now (with the updated response). I just got the parse error when I had a direct look at the php script via the browser (without ajax call, etc.).

Answer 1

The JS code you generate is incorrect. It will look like

callbackName({'status': '1'}{'text' : 'ok})

but you cannot put to object literals after each other.

Either you have to generate one literal:

callback({status: 1, text: 'ok'})

or multiple arguments, separated by commas:

callback({status: 1}, {text: 'ok'})

although I think jQuery expects only one argument to be passed to the callback.
