Question

所以基本上我正在调用MVC控制器并以JSON格式返回查询结果。

<script>
    $("#APINumber").focusout(function () {
        $.getJSON('@Url.Action("CheckAPI", "WellInfo")', { APINumber: $(this).val() }, function (data) {
            if (!data.isDuplicate) {
                toastr.error('API Number does not exist in the database. Please check your API Number.', 'API Number Error')
                $("#APINumber").val("")
            }
            var id = JSON.stringify(data.list);

            $.each(data.list, function (value) {
                viewModel.LeaseName(JSON.stringify(data.list[value]));
            });


        });

    });

我想要做的是从我的查询中提取名为“LeaseName”的值。我创建$ .each循环来尝试解析它们，但我的文本框中填充了 viewModel.LeaseName（JSON.stringify（data.list [value]））; 显示整个JSON字符串！见下文，这就是我得到的。

{"WellKey":221622,"OperatorKey":21,"LeaseKey":519,"APINumber":"03048374","FormattedAPINumber":"030-48374","RedrillCancelFlag":"  ","WellDesignation":"518G1-34","FieldCode":"052","FieldAreaCode":"05200","FieldName":"Belridge, South","AreaCode":"00","AreaName":"Any Area","DistrictNumber":"4","CACountyCode":"030","CountyName":"Kern","LeaseName":"","WellNumber":"518G1-34","IsActive":1,"WellTypeCodeList":"","WellStatusCode":"A","WellStatusDate":"/Date(1342814313397)/","BLMInterestCode":"N","OperatorName":"Aera Energy LLC","OperatorCode":"A0610","IsCurrentActive":true,"Section":34,"Township":"28S","Range":"21E","BaseMeridian":"MD","IsBLMInterest":false,"IsEPAWell":false,"BaseOfFreshWater":"","AssignedEngineerID":-1,"IsHydraulicallyFractured":true,"AbandonedStandardStatusCode":"Not Abandoned","DirectionalStatusCode":"Directionally drilled","LocationDescription":"Fr SW cor 582 N 405 E","Elevation":"592 KB","IsDryHole":false,"Version":4,"Well2Version":3}

我不希望在我的文本框中显示整个内容，我只想从该JSON数据中显示一个SINGLE值。

任何帮助都会很棒!!!!

修改

尝试使用此

            $.each(data.list, function (value) {
                var json = JSON.stringify(data.list[value])
                console.log(json["WellKey"]);
            });

我在控制台中未定义...

编辑2

解决！不需要循环，我想使用$ .getJSON已经将其字符串化，我需要做的就是使用像data.list [0] .FieldName

之类的东西来访问我的数据。

谢谢大家！

Answer 1

从您所写的内容来看，似乎您的字符串太多了。假设

{"WellKey":221622,"OperatorKey":21,"LeaseKey":519,...}

是

的值

data.list[value]

然后简单地做

viewModel.LeaseName(data.list[value].LeaseName);

Answer 2

你只需要：

json["LeaseName"]

见jsFiddle：

但请注意，LeaseName在您返回的json中的值为 no 。

<强>更新

查看您的代码我相信这会输出您的价值：

data["LeaseName"]

当您在getJson电话中时，data变量已经是json。

如果您看一下这个小提琴，它只会以WellKey的相同方式输出一个值，因为它有一个值：
