如何在Javascript中将此日期格式2021-03-30T06:14:00.000Z转换为2021-03-30T06:14:00+00:00此日期格式

// 原始日期格式
const originalDate = "2021-03-30T06:14:00.000Z";

// 创建Date对象
const date = new Date(originalDate);

// 获取年、月、日、时、分、秒
const year = date.getUTCFullYear();
const month = ("0" + (date.getUTCMonth() + 1)).slice(-2);
const day = ("0" + date.getUTCDate()).slice(-2);
const hours = ("0" + date.getUTCHours()).slice(-2);
const minutes = ("0" + date.getUTCMinutes()).slice(-2);
const seconds = ("0" + date.getUTCSeconds()).slice(-2);

// 构建转换后的日期格式
const convertedDate = `${year}-${month}-${day}T${hours}:${minutes}:${seconds}+00:00`;

console.log(convertedDate);
