批量更新记录

Posted 2020-12-05 sunny-technology

界面上通过按钮批量更新数据很常见，列个更新的例子，方便查阅。

销售订单界面，批量更新行地址：

1.定义继承Runbase的类，使用框架更方便

class UpdateSalesLineAddress extends RunBase
{
    DeliveryAddress       deliveryAddress;
    SalesLine               salesLine;
    DialogField             d_deliveryAddress;
}

2.Dilog界面设计：

    public Object dialog()
    {
        Dialog dialog = super();

        dialog.caption("标题");

        d_deliveryAddress = dialog.addField(extendedTypeStr(DeliveryAddress));
        //d_deliveryAddress = dialog.addFieldValue(extendedTypeStr(DeliveryAddress),salesLine.DeliveryAddress);

        return dialog;
    }

3.获取Dialog界面中需要更新的值：

  public boolean getFromDialog()
    {
        boolean ret;

        ret = super();

        deliveryAddress = d_deliveryAddress.value();

        return ret;
    }

4.主方法中进行更新
