jquery - 为什么ajax显示DateTime格式错误 "/Date(1493818989603)/"？

Question

我想将表单发送到MVC Controller Controller 返回DateTime但显示此格式/日期(1493818989603)/。我有一个简单的表单，它包含(一个输入和按钮)。

    [HttpPost]
    [DynamicCache(VaryByParam = "none")]
    public ActionResult DynamicCache(int duration)
    {
        var configuration = WebConfigurationManager.OpenWebConfiguration("~");
        configuration.AppSettings.Settings["Duration"].Value = duration.ToString();
        configuration.Save();

        System.Web.HttpRuntime.UnloadAppDomain();

        var timeNow = DateTime.Now;
        return Json(new { result = timeNow });

    }

                    $("#result").html("Result: " + data.result);
                }
            });
        });
    });
</script>

我已将其添加为答案，以便您可以正确阅读。默认 .NET json 序列化程序返回以下格式的日期:例如/日期(1493818989603)/

如果您定义原型(prototype)函数，例如:

// .NET Date/String converter
if (!String.prototype.parseNETDate) {
    String.prototype.parseNETDate = function () {
        if (this.indexOf('-') == -1) {
            return new Date(parseInt(this.slice(6, 19)));
        } else {
            return new Date(parseInt(this.slice(6, 20)));
        }
    };
}

然后在你的对象上你可以这样做:

var dateParsed = data.result.parseNETDate();

在调用此函数之前，您必须定义该函数。
