代码格式化是这样的：

if (flag == 1 && yemian.shop_price == ‘0.00’) {

    if (yemian.member_price != ‘0.00’) {

        yemian.shop_price = yemian.member_price;

    } else if (yemian.retail_price != ‘0.00’) {

        yemian.shop_price = yemian.retail_price;

    }

}

可不可以做成这样：

if (flag == 1 && yemian.shop_price == ‘0.00’)

{

    if (yemian.member_price != ‘0.00’)

    {

        yemian.shop_price = yemian.member_price;

    }

    else if (yemian.retail_price != ‘0.00’)

    {

        yemian.shop_price = yemian.retail_price;

    }

}

这样感觉很清晰
