使用jsonp而不调用成功回调函数的jQuery .ajax()。

I have a facebook iframe application that makes a cross domain request to my server and requests data in JSONP format. This is my client side code:

我有一个facebook iframe应用程序，它向我的服务器发出跨域请求，并以JSONP格式请求数据。这是我的客户端代码:

jQuery.ajax({
                url: '***',
                type: 'post',
                data: {
                    method: 'set_user_prizes'
                },
                dataType: 'jsonp',
                jsonp: false,
                jsonpCallbackString: 'callback123',
                success: function(data, textStatus, jqXHR){
                    console.log('success_function');
                    console.log(data);
                }
});

The problem is my success callback method isn't being invoked and I'm not sure why. Using Firebug I can see my server's response:

问题是我的成功回调方法没有被调用，我也不知道为什么。使用Firebug，我可以看到我的服务器的响应:

callback123({"success":true,"associated_prizes":[{"prizes_id":"6"},{"prizes_id":"1"}]})

#1

Remove the word String from the callback key as is illustrated in the following transformation. The value needs to remain a string.

从回调键中删除字串，如下面的转换所示。该值需要保持为字符串。

Change:

变化:

jsonpCallbackString: 'callback123',

来

jsonpCallback: 'callback123',
