Question

我有从Dictionary（int，string）中检索数据的下拉列表：

<select 
    class="form-control" 
    data-ng-model="model.Case.OwnerUserId" 
    data-ng-options="key as value for (key,value) in model.OwnerUsers" >
</select>

model.Case.OwnerUserId是int值，我尝试通过ng-model指令绑定并为dropdown设置选定的值。但是未选中下拉列表。我在这种情况下做错了什么？

更新：部分视图模型数据

public class CaseViewModel
{
    public Case Case { get; set; }

    public Dictionary<int,string> Facilities { get; set; }

    public Dictionary<int, string> OwnerUsers { get; set; }
}

public class Case
{
    public int CaseId { get; set; }

    public int ResidentId { get; set; }

    public int OwnerUserId { get; set; } ...

序列化后的JS模型示例：

{
"Case": {
    "CaseId": 27,
    "ResidentId": 4478,
    "OwnerUserId": 15,
    "CreatedByUserId": 20,
    "LastUpdatedUserId": null,
    "ReceivedDate": "2014-06-23T12:49:54.713", ...


"OwnerUsers": {
    "35": "a.markov",
    "15": "a.zaharov",
    "20": "e.martynov",
    "36": "a.oryel",
    "40": "test01"
}

Answer 2

如果要包含值和描述

，请尝试以下操作

key as value for (key , value) in CONTROLLER.DICTIONARY

为Angular中的字典生成的下拉列表设置ng-model
