我正在尝试学习React with TypeScript,我似乎一直遇到有点模糊的TS错误。
我在下面的三个文件中编写了代码,编译和运行时工作正常。我只是不断得到TypeScript抛出的这个错误,超级烦人
“类型”{ id:任意;键:任意;“}"缺少类型”ProfileCardProps“的以下属性:登录,名称”
//表格.tsx
import * as React from 'react';
import Axios from 'axios';
export default class Form extends React.Component<any,any>{
constructor(props: any){
super(props);
this.state = { userName: ""};
}
handleSubmit = (event: React.FormEvent<EventTarget>): void => {
event.preventDefault();
//get request...
.then(resp => {
this.props.onSubmit(resp.data);
console.log(resp.data);
this.setState({userName: ''});
};
public render() {
return(
<div>
<div className="col-sm-12">
<form onSubmit={this.handleSubmit}>
<label>Run lookup:<br />
<input type="text"
value = {this.state.userName}
onChange = {(event) => this.setState({userName: event.target.value})}
placeholder = "Enter Username..." >

<button type="submit">Add user info</button>

};
}

当你传递卡片给ProfileCard组件时,它传递4个属性值。
但你的界面只有两个
添加key和id应该可以解决这个问题。

这种类型的接口使用要求接口的所有成员都为null

我已经花了大约一个小时来找出类似的错误信息,终于明白,我忘了导入适当的接口:)也许这将是有帮助的人...
