将日期字符串从 ISO 8601 格式 (YYYY-MM-DDTHH:mm:ss.sssZ ) 转换为 LWC 中的“MM-DD-YYYY HH:mm”

Question

尝试过：-

const dateStr = '2020-06-21T10:15:00Z',
[yyyy,mm,dd,hh,mi] = dateStr.split(/[/:-T]/)
控制台.log(

${dd}-${mm}-${yyyy} ${hh}:${mi}

)

Split 工作正常，我得到 21-06-2020 10:15。我们如何将 AM/PM 添加到此？

Answer 1

const dateStr = '2020-06-21T10:15:00Z';
const [yyyy, mm, dd, hh, mi] = dateStr.split(/[-:T]/);

// Convert hh to a 12-hour format and determine AM/PM
const hour12 = (hh % 12) || 12; // Ensure 12-hour format, not 0 for midnight
const ampm = hh < 12 ? 'AM' : 'PM';

// Create the formatted date string
const formattedDate = `${dd}-${mm}-${yyyy} ${hour12}:${mi} ${ampm}`;

console.log(formattedDate);
