easyui-combobox绑定json数据

用的C#语言

后台取数据，就不用废话了，先看看序列化json数据

/// <summary>
        /// 对象转JSON
        /// </summary>
        /// <param name="obj">对象</param>
        /// <returns>JSON格式的字符串</returns>
        public static string ObjectToJSON(object obj)
        {
            JavaScriptSerializer jss = new JavaScriptSerializer();
            try
            {
                return jss.Serialize(obj);
            }
            catch (Exception ex)
            {
                throw new Exception("JSONHelper.ObjectToJSON(): " + ex.Message);
            }
        }

public class RoleEntity
    {
        public Int32 RoleID { get; set; }
        public string RoleName { get; set; }
    }

 string writeStr = ClassHelper.ObjectToJSON(SqlDataHelper.GetRoles());
            context.Response.Write(writeStr);

前台调用

<input id="com_roles" class="easyui-combobox" name="role" />

$('#com_roles').combobox({
                url: 'HandlerHelper/RolesBindHandler.ashx', valueField: 'RoleID',
                textField: 'RoleName',
                panelWidth: 150,
                panelHeight: 'auto'
            });

关于组合框各属性的作用，请查看官网API，这里就不赘述
