用useState对设置的值响应fire事件或fire方法

Question

对于这样定义的变量:

const [voivodeshipDict, setVoivodeshipDictValues] = useState<IDictionary[]>([] as IDictionary[]);

对于每个调用'setVoivodeshipDictValues'，我想在值设置后触发其他代码。怎么实现呢?

对不起，我的英语不好。

我想你是在找useEffect()钩子:

useEffect(() => {
// Do stuffs whenever voivodeshipDict is changed
}, [voivodeshipDict])
