我有使用 JSON 响应的 WCF 服务。我想从我在 phonegap android 上的 javascript 从我的 WCF 服务中获取 JSON 字符串。但是当我从我的 javascript 调用 WCF 服务时，来自 WCF 服务的响应是空的。我已经测试调用这个 WCF 服务并且它可以工作。我的javascript错了吗？

这是我的javascript：

<script type="text/javascript">
        function displayText()
        {
            $.ajax(
                    {
                        type: "GET",
                        contentType: "application/json; charset=utf-8",
                        url: "http://10.80.3.73/webservice/Service1.svc/json/weeklyflash/id",
                        dataType: "json",
                        success:function(data){
                            alert(data);
                        },
                        error: function () { 
                            alert("ERROR"); 
                        }
                    });

        }   
</script>

警报消息仅显示[object Object]，当我尝试使用 firebug 跟踪它时，响应为空。

这是来自 WCF 服务的 JSON 字符串：

当您使用 jquery 并指定dataType: 'json'时，jQuery 会在运行时将 json 字符串反序列化为一个 javascript 对象，然后再调用您的成功回调。

您看到的原因[object object] 是：这是 javascript 对象的字符串表示形式。
