数据插入成功但jquery仍然返回错误

Question

我使用以下jQuery通过数据服务插入数据.事件虽然我得到状态响应201并且数据已成功插入我的数据库,但系统仍将其视为错误并给我"失败"警报？

我在这里错过了什么？

$.ajax({
    type: "POST",
    url: "http://localhost:49223/Form/WebDataService.svc/XMLForm(guid'1eaef3a0-d6df-45bf-a8f6-3e7292c0d77e')/XMLRecord/",
    data: JSON.stringify(record),
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function() {
        alert("Success");
    },
    error: function(xhr) {
        alert("fail");
    }
});

get readyState 4

get responseText "{ "d" : {\r\n"__metadata"...\')/XMLForm"\r\n}\r\n}\r\n} }"

get responseXML null

get status 201

get statusText "Created"

Answer 1

您必须发送{dataType:'text'}才能使成功函数与jQuery和空响应一起使用.

即使我仍然无法解决我如何从以前的代码中获得错误,我得到了这个替代解决方案,对我有用.(至少现在(是).
