我正在学习React并构建一个CV申请表。
我在将表单中的值存储到数组中的对象时遇到了问题。这很奇怪，因为它似乎对未定义的变量有效，但对已定义的位置变量无效。
我假设我可以让一个对象保持一种状态，换句话说，我不必为每个表单输入都有单独的状态。

import { useState } from 'react';
function EducationInfo() {
  const [input, setInput] = useState([]);
  const onChange = (e) => {
    const { name, value } = e.target;
    console.log(`${name}: ${value}`);
  };
  const addEducation = () => {
    const educationNew = {
      school: school.value, // 'school' is undefined, red squiggly line in vsCode
      degree: degree.value, // 'degree' is undefined, red squiggly line in vsCode
      startDate: startDate.value, // 'startDate' is undefined, red squiggly line in vsCode
      endDate: endDate.value, // 'endDate' is undefined, red squiggly line in vsCode
      location: location.value, // actual variable but undefined when saving to array.
    };
    setInput([...input, educationNew]);
  };
  console.log(input);
  return (
    <>
      <form onSubmit={(e) => e.preventDefault}>
        <h2>Experience</h2>
        <div className='experienceContainer'>
          <label htmlFor='school'>School</label>
          <input type='text' name='school' id='school' onChange={onChange} />
          <label htmlFor='degree'>Degree</label>
          <input type='text' name='degree' id='degree' onChange={onChange} />
          <div className='dateContainer'>
            <label htmlFor='startDate'>Start Date</label>
            <input type='date' name='startDate' id='startDate' onChange={onChange} />
            <label htmlFor='endDate'>End Date</label>
            <input type='date' name='endDate' id='endDate' onChange={onChange} />
          </div>
          <label htmlFor='location'>Location</label>
          <input type='text' name='location' id='location' onChange={onChange} />
        </div>
        <button
          className='SubmitBtn'
          type='button'
          onClick={addEducation}
          onSubmit={(e) => e.preventDefault}
        >
          Save
        </button>
      </form>
    </>
  );
}
export default EducationInfo;
