这是我第一次进入React,我知道React鼓励单向数据流.我觉得我正在使用jQuery来处理事件而正确地更新兴趣小组.我想知道一些替代兴趣小组更新的方法.

从我所看到的,为了更新父级(我相信它在React文档中称为所有者)组件,您需要在child / ownee组件上定义回调.我会感谢对此的解释,如果我不正确地使用国家vs道具的利益.我试图只有搜索过滤器&复选框是窗口小部件的状态的一部分,因为我看到可过滤的数据应该属于道具.

更新：我改变了要在getDefaultProps中初始化的兴趣,所以现在我将它们用作道具.我认为这更是反动的方式,我是对的吗？我还通过更改handleCategoryRowClick函数来改变兴趣的更新方式.我认为我现在正在做的事情更为反应,但仍然会喜欢任何有使用React的经验的人都可以给予任何建议,谢谢.

任何帮助将不胜感激！
