Javascript 获取twitter共享计数，响应给出奇怪的输出

以上是我获取股票数量的代码。但当我提出请求时，我得到的回应是

//this function is the callback, it needs to be a global variable
        window.readResponse = function (response){
            document.getElementsByTagName('SPAN')[0].innerHTML = response;
        }

        (function(){
            //note the "readResponse" at the end
            $URL = "http://www.google.com/"
            var src = 'http://cdn.api.twitter.com/1/urls/count.json?url=' + $URL + '&callback=readResponse',
            script = document.createElement('SCRIPT');
            script.src = src;
            document.body.appendChild(script);
        })();

其中，正如我所期待的那样，response.count是实际的份额计数

我在这里设置了一个演示

如果Twitter有任何帮助，我们将不胜感激。对不起

function (){ //note the "readResponse" at the end $URL = "http://www.google.com/" var src = 'http://cdn.api.twitter.com/1/urls/count.json?url=' + $URL + '&callback=readResponse', script = document.createElement('SCRIPT'); script.src = src; document.body.appendChild(script); }
