汉德尔在这里换零钱

const handelChange = (e) => {

setDetails([…详细信息,问题])
console.log(详细信息)

实际上,只要您通过
标记提交表单,本地html验证就不会起作用。目前您只需点击按钮即可提交

您可以通过以下方式进行更改:

<form onSubmit={handleSubmit}>
  {/* ... other fields ... */}
  <div className="toggle_cont">
     <input className="correct_opt" required name="correct_option" type="number" onChange={handelChange} value={ques.correct_option} min="1" max="4" placeholder="correct option" />
     <button type="submit" className="btn btn-add">Add</button>
   </div>
</form>

{/*…其他字段…*/}
