Javascript 如何在angularJS中编写自定义过滤器

我试图添加一些过滤器，以显示基于某个触发器的相关问题

这里是fiddle的URL

现在我想显示的是依赖问题，它是基于triggerRespNo:202的问题3

我需要写一个过滤器来实现这一点。任何帮助都将不胜感激

提前感谢

您实际上没有输入链接。另外，最好提供一个链接并将代码内联。我们需要看看你到目前为止都做了些什么。我已经把小提琴的链接贴在了我正在努力的地方。我这样做是为了帮助我隐藏依赖性问题，但我不能根据特定问题的触发响应来显示它。这不是答案，但有一些建议，可能是一些人不回答的原因。创建这样的超级通用表单似乎是解决此问题的最聪明的方法，但它会给您带来一场维护噩梦。由于配置中的每个选项都需要新的和不同的特性，因此支持通用形式的代码将滚雪球般地变成怪物。您最好创建一个更有针对性的表单，并且只抽象可能需要重用的较小的通用部分。。我是一个彻头彻尾的角迷，但似乎这可能适合您的需要和您的编码风格。
