将表单转换为 JSON [重复]

Question

我需要获取表单的值并将其转换为 JSON。虽然“tickets”、“DriverAge”和“PurchaseDateYear”字段需要转换为 int，但其余字段仍为字符串。我的目标是能够从用户输入中获取数据，更改某些输入的数据类型并将其全部放入 JSON。解决此问题的最佳方法是什么。

运行代码，写入表单，提交即可查看JSON格式的表单数据。

const submitBtn = document.querySelector('button[type="submit"]');
const form = document.querySelector('form');

submitBtn.addEventListener('click', (e) => {
  e.preventDefault();
  const data = new FormData(form);
  const json = Object.fromEntries(data.entries());
  console.log(json);
});
