javascript - 当我在phonegap android上从javascript调用WCF服务时，为什么来自WCF服务的响应为空？

我已经用JSON响应了WCF服务。我想从phonegap android上的JavaScript从WCF服务获取JSON字符串。但是，当我从JavaScript调用WCF服务时，来自WCF服务的响应为空。我已经测试过将此呼叫称为WCF服务，并且可以正常工作。我的JavaScript错误吗？

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进行跟踪时，响应为空。

这是来自WCF服务的JSON字符串：

{"GetReportIdResult":[{"bulan":"4","total":"1728","type":"CHEESE1K","uang":"8796383"},{"bulan":"4","total":"572476","type":"ESL","uang":"5863408410"},{"bulan":"4","total":"46008","type":"ESL500ML","uang":"234498301"},{"bulan":"4","total":"190369","type":"UHT","uang":"1367063805"},{"bulan":"4","total":"33507","type":"WHP","uang":"235653242"},{"bulan":"5","total":"4761","type":"CHEESE1K","uang":"134877865"},{"bulan":"5","total":"648663","type":"ESL","uang":"6645764498"},{"bulan":"5","total":"49305","type":"ESL500ML","uang":"266817346"},{"bulan":"5","total":"245867","type":"UHT","uang":"1446787280"},{"bulan":"5","total":"47974","type":"WHP","uang":"631929807"},{"bulan":"6","total":"5762","type":"CHEESE1K","uang":"293393832"},{"bulan":"6","total":"594942","type":"ESL","uang":"6088671790"},{"bulan":"6","total":"39457","type":"ESL500ML","uang":"221983181"},{"bulan":"6","total":"236803","type":"UHT","uang":"2219506085"},{"bulan":"6","total":"24853","type":"WHP","uang":"386175022"}]}

最佳答案

当您使用jquery并指定dataType: 'json'时，jQuery在调用成功回调之前会在运行时将json字符串反序列化为javascript对象。

您看到[object object]的原因：这是字符串的表示形式
一个javascript对象。
