使用 jQuery.TypeAhead 让文本框自动完成 （三）（服务器返回 JSON 复杂对象数组）

项目地址：https://github.com/twitter/typeahead.js

直接贴代码了：

@section headSection
{
    <script type="text/javascript">
    $(document).ready(function () {
        var bestPictures = new Bloodhound({
          datumTokenizer: Bloodhound.tokenizers.obj.whitespace('value'),
          queryTokenizer: Bloodhound.tokenizers.whitespace,
          identify: function(obj) { return obj.id; } /* 这个函数是告诉引擎对象的 ID */,
          remote: {
            url: '@Url.Action("Trade_Code_List_Search_By_Trad_Cod")?searchTradCode=%QUERY',
            wildcard: '%QUERY'
          }
        });

        $('#trad_cod_textbox').typeahead(null,{
            name: 'best-pictures',
            source: bestPictures,
            display: 'value',
            limit:10
        }).bind('typeahead:select', function(ev, suggestion) {
            alert("you select: " + "(id=" + suggestion.id + ", value="+ suggestion.value +")"); //绑定自定义事件
        });
    });
    </script>
}
@Html.Partial("UCjQueryTypeAheadJsScript")

<!-- 这里就是文本框 -->
<input id="trad_cod_textbox" class="text-input" type="text" value="">

UCjQueryTypeAheadJsScript.cshtml

<!-- both bloodhound.js and typeahead.jquery.js have a dependency on jQuery 1.9+. -->

Controller.cs

        public ActionResult Trade_Code_List_Search_By_Trad_Cod(string searchTradCode)
        {
            List<Trd_Mas_Simple_Info> simpleTradMasList = new Trd_MasService().GetSimpleListByTradCode(searchTradCode);
            return Json(simpleTradMasList.Select(c => new
            {
                value = c.trd_cod + " - " + c.trd_des,
                id = c.trd_cod
            }), JsonRequestBehavior.AllowGet);
        }
