At.js @mention - C# Web API

Question

我正在使用 https://github.com/ichord/At.js 库来实现自动完成。

但是当我像他们在 https://github.com/ichord/At.js/wiki/How-to-use-remoteFilter 中所说的那样使用 remoteFilter 时，它会显示 "undefined" 下拉列表。

型号：

public class CaseHistory
{
    public int CaseHistoryId { get; set; }


    [Display(Name = "Symptom/Disease")]
    [Required(ErrorMessage = "Please enter symptom or disease")]
    public string SymptomOrDisease { get; set; }

    public string Description { get; set; }

}

API 操作代码：

   private ApplicationDbContext db = new ApplicationDbContext();

    // GET api/CaseHistories
    public IQueryable<CaseHistory> GetCaseHistories()
    {
        return db.CaseHistories;
    }

这是我在剃刀视图中的代码：

    var myUrl = 'https://localhost:44301/api/CaseHistories';

    $('#inputor').atwho({
    at: ":",
    callbacks: {
        /*
         It function is given, At.js will invoke it if local filter can not find any data
         query [String] matched query
         callback [Function] callback to render page.
        */
        remoteFilter: function(query, callback) {
            $.getJSON(myUrl, { q: query }, function (data) {
                callback(data);
            });
        }
    }
    });

将控制器中的代码更改为：

   public dynamic GetCaseHistories()
    {
        return db.CaseHistories.Select(x => x.SymptomOrDisease).ToList();
    }

问题是您传递给回调的参数应该是字符串数组。

如果你真的想在 js 中这样做：

    var myUrl = 'https://localhost:44301/api/CaseHistories';

    $('#inputor').atwho({
    at: ":",
    callbacks: {
        /*
         It function is given, At.js will invoke it if local filter can not find any data
         query [String] matched query
         callback [Function] callback to render page.
        */
        remoteFilter: function(query, callback) {
            $.getJSON(myUrl, { q: query }, function (data) {
            var targetData = [];
                for(var i = 0;i < data.length;i++){
                        targetData.push(data[i].SymptomOrDisease);
                }
                callback(targetData);
            });
        }
    }
    });
