salesforce Lightning -- 练习Demo添加订单产品

订单添加订单产品

继上一篇博文，已经介绍过，怎样去初始化一个组件，怎样通过一个记录上的button调用组件，以及组件中的各个组块之间起什么作用等。
本篇继续延续上一个文章，简单的搭建一个lightning页面的Demo出来。

批量添加订单产品，我相信这个场景大家应该都有遇到过，可能会涉及到产品的检索，分页。添加价格，数量等操作。下面我们通过lightning的模块实现该功能，主要是体验lightning中的数据传递。

涉及对象：

1. 订单对象
   

2. 订单产品
   

3. 产品
   

实现效果：

总结：这个一个简单的Demo页面，UI没经过涉及的简版，并且功能上也是比较简单的，只是实现了批量添加订单产品的一个功能。
Tips：
1，未使用自定义事件
2，一些细节的逻辑未经过处理，还是存在BUG
