asp.net mvc将ViewBag字典显示为javascript

我是C＃asp.net mvc中的新成员。 我正在制作一个ViewBag，其中包含控制器中的Dictionary数据类型，我想通过.cshtml中的javascript获取并显示值，以便用googlemaps函数对其进行编码。

这里是我的控制器字典和视图代码：

Dictionary<string, string> alamatVehicleMarker = new Dictionary<string, string>();
alamatVehicleMarker.Add("v1","Bali");
alamatVehicleMarker.Add("v2","Jakarta");
alamatVehicleMarker.Add("v3","Bandung");

ViewBag.getAlamatVehicle = alamatVehicleMarker;

你能帮助我如何获得ViewBag.getAlamatVehicle和如何循环它请

EDITED

我试过这个：

<script>
function GetViewBagDictionary(id) {

            @foreach (var item in ViewBag.getAlamatVehicle)
            {
                var key = item.Key;
                var Value = item.Value;

                if (key == id)
                {
                    return Value;
                }
            }

            return "not found";
        }
<script>

但在if函数内部会出现一个错误： The name 'id' does not exist in the current context

像这样的东西只会小心数据类型

var dictionary = @Html.Raw(Json.Encode(ViewBag.getAlamatVehicle));
for(var key in dictionary ){
    var value = dictionary[key];
    console.log(value);
}

以下是我如何将VeiwBag转换为JavaScript的ViewBag对象

<script type="text/javascript">
var ViewBag = {
    IsDesigner: ("@ViewBag.IsDesigner").toLowerCase() === 'true',
    IsAdmin: ("@ViewBag.IsAdmin").toLowerCase() === 'true',
    EmptyGuid: "@ViewBag.EmptyGuid",
    Advertisers_ID: "@ViewBag.Advertisers_ID",
    Primary_Category: "@ViewBag.Primary_Category",
    Primary_Category_ID: "@ViewBag.Primary_Category_ID",
    Advertiser_Name: "@ViewBag.Advertiser_Name",
    Advertiser_NameMM: "@ViewBag.Advertiser_NameMM",
    BookTypeName: "@ViewBag.BookTypeName",
    getAlamatVehicle: { 
        @{
            int marker_count = 0;
            string markers_str = "";                
            foreach (var item in ViewBag.getAlamatVehicle) 
            {
                markers_str += """ + item.Key + "": "" + item.Value + """;
                marker_count++;
                if (marker_count < ViewBag.getAlamatVehicle.Count)
                {
                    markers_str += ", ";
                }
            }
            var html_str = new HtmlString(markers_str);
        }
        @html_str
    }
}
console.log(ViewBag.getAlamatVehicle);
</script>

结果：

var ViewBag = {
    IsDesigner: ("False").toLowerCase() === 'true',
    IsAdmin: ("True").toLowerCase() === 'true',
    EmptyGuid: "00000000-0000-0000-0000-000000000000",
    Advertisers_ID: "7e49def2-3887-4149-b419-5f1f51d4ec58",
    Primary_Category: "Construction Services",
    Primary_Category_ID: "ca9381c7-0379-4a72-80df-270287954164",
    Advertiser_Name: "Dolphin Ayeyarwady Pile Construction Co., Ltd.",
    Advertiser_NameMM: "",
    BookTypeName: "YD",
    getAlamatVehicle: { 
        "v1": "Bali", "v2": "Jakarta", "v3": "Bandung"
    }
}

安慰：

Object {v1: "Bali", v2: "Jakarta", v3: "Bandung"}

以下是您可以如何实现该功能的方法：

function GetViewBagDictionary(id) {
    if (ViewBag.getAlamatVehicle.hasOwnProperty(id))
        return ViewBag.getAlamatVehicle[id];
    return "not found";
}
console.log(GetViewBagDictionary("v2"));

安慰：

Jakarta

测试：

console.log(GetViewBagDictionary("v4"));

安慰：

not found

请尝试在JavaScript中foreach循环。

         function GetViewBagDictionary() {

            @foreach (var item in ViewBag.getAlamatVehicle)
             {
                 var key = item.Key;
                 var Value = item.Value;
             }


            }
