        success: function (layero, index) {
            //alert(layero +"00000"+ index);
            var Childbody = layer.getChildFrame('body', index); //获取弹框DOM
            Childbody.find('#nav_hiddn').hide(); //隐藏弹出框元素，已实现

            //获取基层的值打算赋值给弹出框，已实现
            Childbody.find('#弹出层元素id').val($('#基层元素id').val());

            //用基层值当做参数运行弹窗里的js方法，无效
            selectPerson( $("#基层元素id").val());
        }
    });
}
