我刚刚学会了一些东西在React和尝试实践对我自己我有一个小问题.我试图得到一个输入字段的数据都到一个对象.即用户名字段和值与密码字段和值应该是这样的
{username:"bob", password:1234}
但是我得到的结果是这样的
{inputName:1234}
输入名称是保存输入字段的名称属性的变量。
整个代码是这样的。

import './App.css';
import { useState } from 'react';

export default function Login() {
  const [inputs, setInputs] = useState({});

  const [username, setUsername] = useState('');

  const [password, setPassword] = useState('');

  const saveInputData = (e) => {
    let inputName = e.target.name;

    let inputValue = e.target.value;

    inputName == 'username' ? setUsername(inputValue) : setPassword(inputValue);
    setInputs({ ...inputs, inputName: inputValue });
  };

  const submitForm = () => {
    console.log(inputs);
  };

  return (
    <div className='container box'>
      <div className='columns is-mobile df'>
        <div className='column is-full-mobile'>
          <figure className='image is-5by3 box'>

          </figure>

我试图检查inputName变量的值,并显示它应该与On change事件。
提前感谢您的帮助!!!

有更简单的方法可以实现这一目标。但更简单的方法是改变:

setInputs({ ...inputs, inputName: inputValue });

setInputs({username, password});

为了使用变量作为对象中的键,你需要用[] Package 它,尝试更改这一行:

setInputs({ ...inputs, inputName: inputValue });

致:

setInputs({ ...inputs, [inputName]: inputValue });

除此之外,我认为保存一个inputs状态加上一个usernamepassword的单独状态有点多余,要么只保存输入,要么保存用户名和密码,然后在提交构建对象时...
