使用 useState 对设定值反应触发事件或触发方法
React fire event or fire method on set value with useState
对于这样定义的变量:
const [voivodeshipDict, setVoivodeshipDictValues] = useState<IDictionary[]>([] as IDictionary[]);
对于每个调用 'setVoivodeshipDictValues' 我想在设置值后触发其他代码。热衷于实施吗?
对不起我的英语。
我想你正在寻找 useEffect()
钩子:
useEffect(() => {
// Do stuffs whenever voivodeshipDict is changed
}, [voivodeshipDict])
