Nisbiy sanani formatlash
formatDate(sana) funktsiyasini yozing, u sana ni quyidagicha formatlashi kerak:
- Agar
sana1 soniyadan kam vaqt o’tgan bo’lsa,"hozir". - Aks holda, agar
sana1 daqiqadan kam vaqt o’tgan bo’lsa, unda"n soniya oldin". - Aks holda, agar bir soatdan kam bo’lsa, unda
"m min oldin". - Aks holda,
"DD.MM.YY HH:mm"formatidagi to’liq sana. Ya’ni:"kun.oy.yil soat:daqiqa", barchasi 2 xonali formatda, masalan,31.12.16 10:00.
Misol uchun:
alert(formatDate(new Date(new Date() - 1))); // "hozir" alert(formatDate(new Date(new Date() - 30 * 1000))); // "30 soniya oldin" alert(formatDate(new Date(new Date() - 5 * 60 * 1000))); // "5 daqiqa oldin" // 31.12.2016, 20:00 kabi kechagi sana alert(formatDate(new Date(new Date() - 86400 * 1000)));Sana dan hozirgi kungacha bo’lgan vaqtni olish uchun – sanalarni qisqartiraylik.
function formatDate(date) { let diff = new Date() - date; // millisekundlardagi farq if (diff < 1000) { // 1 soniyadan kam return "right now"; } let sec = Math.floor(diff / 1000); // farqni soniyalarga aylantirish if (sec < 60) { return sec + " sec. ago"; } let min = Math.floor(diff / 60000); // farqni daqiqaga aylantirish if (min < 60) { return min + " min. ago"; } // sanani formatlash // bir joylik kun/oy/soat/daqiqaga yetakchi nollarni qo'shish let d = date; d = [ "0" + d.getDate(), "0" + (d.getMonth() + 1), "" + d.getFullYear(), "0" + d.getHours(), "0" + d.getMinutes(), ].map((component) => component.slice(-2)); // har bir komponentning oxirgi 2 ta raqamini oling // tarkibiy qismlarni sanaga qo'shiling return d.slice(0, 3).join(".") + " " + d.slice(3).join(":"); } alert(formatDate(new Date(new Date() - 1))); // "hozir" alert(formatDate(new Date(new Date() - 30 * 1000))); // "30 soniya oldin" alert(formatDate(new Date(new Date() - 5 * 60 * 1000))); // "5 daqiqa oldin" // kechagi sana kabi 31.12.2016, 20:00 alert(formatDate(new Date(new Date() - 86400 * 1000)));Muqobil yechim:
function formatDate(date) { let dayOfMonth = date.getDate(); let month = date.getMonth() + 1; let year = date.getFullYear(); let hour = date.getHours(); let minutes = date.getMinutes(); let diffMs = new Date() - date; let diffSec = Math.round(diffMs / 1000); let diffMin = diffSec / 60; let diffHour = diffMin / 60; // formatlash year = year.toString().slice(-2); month = month < 10 ? "0" + month : month; dayOfMonth = dayOfMonth < 10 ? "0" + dayOfMonth : dayOfMonth; hour = hour < 10 ? "0" + hour : hour; minutes = minutes < 10 ? "0" + minutes : minutes; if (diffSec < 1) { return "right now"; } else if (diffMin < 1) { return `${diffSec} sec. ago`; } else if (diffHour < 1) { return `${diffMin} min. ago`; } else { return `${dayOfMonth}.${month}.${year} ${hour}:${minutes}`; } }
