EasyUI设置Combobx类型

前台代码：

<input class="easyui-combobox" name="ProcessType" style="width: 150px;"
                data-options="valueField:'id',textField:'text',url:'GetProcessType',required:'true'" panelHeight="auto" editable="false"/>

 

后台代码，返回Json格式数据：

public ActionResult GetProcessType()
{
            DataTable dt = DAL.DBConn.GetDataTable("select userid,name from sys_user where userid='A01'");
            var query = from p in dt.AsEnumerable()
                        select new
                        {
                            id = p["userid"].ToString(),
                            text = p["name"].ToString()
                        };

            return Json(query, JsonRequestBehavior.AllowGet);
}
