我正在尝试使用React钩子解决一个简单的问题
const [personState,setPersonState] = useState({ DefinedObject });
具有以下依赖性。
"dependencies": {
"react": "^16.8.6",
"react-dom": "^16.8.6",
"react-scripts": "3.0.0"
}
但我仍然收到以下错误:
./src/App.js
第7行:
在函数“ app”中调用React Hook“ useState”,该函数既不是React函数组件也不是定制的React Hook函数react-hooks / rules-of-hooks第39行: 未定义
“状态”搜索关键字以了解有关每个错误的更多信息。
组件代码如下:
import React, {useState} from 'react';
import './App.css';
import Person from './Person/Person';
const app = props => {
const [personState, setPersonSate] = useState({ person:[ {name:'bishnu',age:'32'}, {name:'rasmi',age:'27'}, {name:'fretbox',age:'4'} ], });
return (
<div className="App">
<h2>This is react</h2>
<Person name={personState.person[1].name} age="27"></Person>
<Person name={personState.person[2].name} age="4"></Person>
</div> );
};
export default app;
人组成
import React from 'react';
const person = props => {
return(
<div>
<h3>i am {props.name}</h3>
<p>i am {props.age} years old</p>
<p>{props.children}</p>
</div>
)
};
export default person;
