在 React JS 中忘记密码 [英] Forget password in React JS

问题描述

在我的登录页面中，我有一个忘记密码"按钮，我需要，当我点击这个按钮进入正确的页面时.

在我当前的代码中，当我单击忘记密码"时，它会显示在登录名下方，这意味着在同一页面上我会看到登录名"和忘记密码".

我只需要看到忘记密码"页面.

这是我的代码:

<预><代码>从反应"导入反应；从../ForgetPasswrod/Forgotpass"导入 ForgetPage从'react-router-dom'导入{Link，useParams，useRouteMatch，Route，Switch，BrowserRouter}；class Forget 扩展 React.Component{忘记密码 -使成为(){//让匹配 = useRouteMatch();返回(<div><浏览器路由器>{" "} <Link to="/forgetPassword" className="forget">忘记密码?</Link><开关><Route path="/forgetPassword" 精确的严格组件={(ForgetPage)}/></开关></BrowserRouter>

);}}导出默认忘记；

登录页面

从react"导入React；从./UserName"导入用户名；从./Password"导入密码；从./Submit"导入提交；从./RememberMe"导入Rememberme；从./Cancel"导入取消；从./Forget"导入 ForgetPassclass Hub 扩展 React.Component {状态={用户名:登录"，密码:在"}回调用户名=(用户)=>{this.setState({用户名: 用户});console.log("---"+用户)}callbackPassword = (pass) =>{this.setState({密码:pass});}使成为(){返回(<div><h1>{this.state.userName} {this.state.password}</h1><form className="modal-content animate"><用户名 userHub={this.callbackUsername}/><密码 passHub={this.callbackPassword}/><提交/><记住我/><div className="容器"><取消/><忘记通行证/>

</表单>

);}}导出默认集线器；

解决方案

请试试这个例子:

从react"导入React；导出默认类登录扩展 React.Component {构造函数(道具){超级(道具)；this.state = {忘记:假}；}登录() {alert('登录将在这里工作');}忘记() {this.setState({忘记: true})}使成为() {返回 (<div>{this.state.forgot === false &&<div>用户名:<输入/><br/>密码:<input/><br/><button onClick={this.forgot.bind(this)}>忘记</button><button onClick={this.login.bind(this)}>登录</button></div>}{this.state.forgot === true &&<忘记密码/>}

);}}class ForgotPassword 扩展 React.Component {重启() {alert('密码已发送至您的邮箱');}使成为() {return (<div><h1>写你的电子邮件</h1><输入/><button onClick={this.reset.bind(this)}>重置密码</button></div>)}}

In my log in page I have a button "Forget my password", I need, when I click in this button to go to the correct page.

In my current code, when I click "forget my password", it shows under the login, which mean at the same page I see the "login" and the "forget password".

What I need is to see just the "forget my password" page.

Here is my code :

import React from "react";
import ForgetPage from "../ForgetPasswrod/Forgotpass"
import {Link,useParams,  useRouteMatch,Route, Switch, BrowserRouter} from 'react-router-dom';

class Forget extends React.Component{

   Forget password -

render(){
  //  let  match = useRouteMatch();
    return(
        <div>

        <BrowserRouter>
        {" "} <Link to="/forgetPassword"  className="forget">Forgot password?</Link>
        <Switch>
          <Route  path="/forgetPassword" exact strict component={(ForgetPage)} />
        </Switch>
        </BrowserRouter>


        </div>);

}

}

export default Forget;

The page of log in

import React from "react";
import Username from "./UserName";
import Password from "./Password";
import Submit from "./Submit";
import Rememberme from "./RememberMe";
import Cancel from "./Cancel";
import ForgetPass from "./Forget"

class Hub extends React.Component {


state={userName:"Log", password : "In"}

callbackUsername=(user)=>{
    this.setState({userName: user});
    console.log("---"+user)
}


callbackPassword = (pass) => {
     this.setState({ password: pass});
  }


render(){
return(
<div>
<h1> {this.state.userName} {this.state.password}</h1>
    <form className="modal-content animate">

        <Username userHub={this.callbackUsername}/>
        <Password passHub={this.callbackPassword}/>

        <Submit/>
        <Rememberme/>

        <div className="container">
            <Cancel/>     
        <ForgetPass/>


        </div>
    </form> 
</div>

);
}
}

export default Hub;

解决方案

Please try this example:

import React from "react";

export default class Login extends React.Component {
    constructor(props) {
        super(props);
        this.state = {forgot: false};
    }

    login() {
        alert('Login will work here');
    }
    forgot() {
        this.setState({forgot: true})
    }

    render() {
        return (
            <div>
                {this.state.forgot === false && <div>
                    Username: <input/> <br/>
                    Password: <input/><br/>
                    <button onClick={this.forgot.bind(this)}>Forgot</button>
                    <button onClick={this.login.bind(this)}>Login</button>
                </div>}
                {this.state.forgot === true && <ForgotPassword/>}
            </div>
        );
    }
}

class ForgotPassword extends React.Component {

    reset() {
        alert('Password is sent to your email');
    }

    render() {
        return (<div><h1>Write your email</h1>
            <input/>
            <button onClick={this.reset.bind(this)}>Reset Password</button>

        </div>)
    }
}
