EasyUI combobox无法显示下拉框？ 后台已经返回了正确的 JSON 格式的值

Question

前台代码：

 <div class="fitem">
            <label>户主名称:</label>
                   <input id="Name" name="holderName" class="easyui-combobox"
                    data-options="valueField:'holder_id', textField:'holderName',panelHeight:'70', url:'ashx/GetName.ashx' " />
        </div>

后台代码：

public void Query(HttpContext context)
{
//调用B层的方法从而获取数据库的Dataset

ADO.SqlAdo ado = new ADO.SqlAdo();
string sql = "select holder_id,holderName from t_householdsInfo";
DataSet ds = ado.getTable(sql);
//将Dataset转化为Datable

DataTable dt = ds.Tables[0];
int count = dt.Rows.Count;
string strJson = Dataset2Json(ds, count);//DataSet数据转化为Json数据

context.Response.Write(strJson);//返回给前台页面

context.Response.End();

返回的json:

{"total":5,"rows":[{"holder_id":"2","holderName":"王晓宇"},{"holder_id":"3","holderName":"小苏"},{"holder_id":"4","holderName":"万面"},{"holder_id":"7","holderName":"我的家"}

Answer 1

直接返回:[{"holder_id":"2","holderName":"王晓宇"},{"holder_id":"3","holderName":"小苏"},{"holder_id":"4","holderName":"万面"},{"holder_id":"7","holderName":"我的家"}]

不要total，rows这种属性，combobox数据源和datagrid不一样

要么就配置loadFilter返回rows属性

<input id="Name" name="holderName" class="easyui-combobox"
                    data-options="valueField:'holder_id', textField:'holderName',panelHeight:'70', url:'d.txt',loadFilter:function(d){ return d.rows} " />
