一个6年的菜鸟,在4年之前做的一些功能(二)

前戏:针对上一篇列出来的功能点,今天和大家分享下这个自定义的公式是怎么设计的,由于我的第一篇博客在首页被管理员移走了,大家可以点击这里来跳转,看下第一篇的目录结构。本人作为老菜鸟,和大家分享的也是一些老菜鸟的想法,大神千万别喷我.

设计背景:当初为什么要设计这个自定义的计算公式呢,原因就是,这个价格是不确定的,计算方式也是不确定的,那如果在代码里面写死,那将来修改起来会比较麻烦,作为老菜鸟,我想偷懒了,也是为了省事。

如何设计:这对目前项目的情况,计算的过程应该是按照线性的方式来计算的,那么问题就简单了。

首先我们先要定义一个范围控件,这个控件的目的就是,在某个区间之内,设置固定的金额或者单价,

350

那么对于上限,其实他也是个线性的,那么我们也来建立一个控件

这个控件用来计算最后临界值。

到此以上就是设置了定义计算规则的逻辑,是不是很简单,有了这些数据的规则之后,接下来就是解析这些数据了,有兴趣的朋友可以自己设计下,然后自己解析,因为这些在老菜鸟看来这些都是儿科的玩意,好了今天就和大家分享到这里,明天给大家分享下,我这个老菜鸟是如何开发发票设计器的,如何来动态设计发票模板,各位88
