如何使用JavaScript将日期"Wed Jan 01 2020 00:00:00 GMT+0530 (印度标准时间)“转换为2020年1月01日？

var dateStr = "Wed Jan 01 2020 00:00:00 GMT+0530 (印度标准时间)";
var dateObj = new Date(dateStr);

var year = dateObj.getFullYear();
var month = dateObj.getMonth() + 1; // 月份从0开始，需要加1
var day = dateObj.getDate();

var formattedDate = year + "年" + month + "月" + day + "日";

var dateStr = "Wed Jan 01 2020 00:00:00 GMT+0530 (印度标准时间)";
var dateObj = new Date(dateStr);
var year = dateObj.getFullYear();
var month = dateObj.getMonth() + 1;
var day = dateObj.getDate();
var formattedDate = year + "年" + month + "月" + day + "日";

console.log(formattedDate);
