我正在使用mongodb创建注册登录模块,表达并做出反应,但是在创建该模块时我遇到的属性历史记录不存在错误:
类型'Readonly&Readonly <{子代?:ReactNode; }>'。ts(2339)
import React, { Component } from 'react'
import { login } from './userfunctions'
interface userprops{}
interface data{
email:string;
password:string;
errors: string;
}
//主类:
class Login extends Component<userprops, data> {
constructor(props: userprops) {
super(props)
this.state = {
email: '',
password:'',
errors: ''
}
this.onChange = this.onChange.bind(this) //binding the function
this.onSubmit = this.onSubmit.bind(this) //binding the function
}
onChange(e:any) { //on change function
this.setState({ email: e.target.value })
}
onSubmit(e:any) { //on submitting the form in render function this function will fire
e.preventDefault()
const user = {
email: this.state.email,
password: this.state.password
}
login(user).then(res => { //I had created login function in another component
if (res) {
this.props.history.push(`/profile`) //this line is giving error
}
})
}
render() {
//rendering data
}
export default Login
错误消息:
类型'Readonly&Readonly <{子代?:ReactNode; }>'。ts(2339)
我尝试了很多事情,但是不会出错
这应该运行
答案 0 :(得分:0)
我猜你在用反应路由器
如果这样,您可以使用确切的类型扩展接口,路由器将传递给您的组件
import { RouteComponentProps } from 'react-router-dom';
interface userprops extends RouteComponentProps {}
