salesforce Lightning - Lightning Demo实例

salesforce Lightning 批量操作,及分页
前段时间简单整理了一下,使用lightning的开发方式做一个批量添加产品的功能。近期我又去对这个功能点增加了一些逻辑,比如分页,批量操作等。
总体来说还是一个批量添加产品的功能吧。

Tips:

  1. 使用按钮弹出的页面,是不能使用标准的那种提示的,这是一个saleforce 团队的 一个已知bug
  2. 使用css样式调节弹出页面的宽度,是不能够放到css中写的,这个目前不知道什么原因导致的,只能放到comment中写样式。
  3. 如果将样式写在comment中,那么对于comment的版本是有要求的,目前我使用的是41.0版本的。

这此首先做一个Demo的展示效果给大家:

这次我们换了两个对象去使用,一个是使用的Contract,另外一个使用的是自定义的Product。 因为项目搭建Demo的时候突然变了。。。。所以可能代码中有些变量的命名还是没换过来,不过应该不影响阅读。

先贴代码如下:
