Isonjululwe: i-javascript guqula imilliseconds ukuya ku-hh mm ss

Ingxaki ephambili yokuguqula i-millisecond kwiiyure, imizuzu, kunye nemizuzwana kukuba azihlali zihambelana. Umzekelo, ukuba uguqula i-10,000 milliseconds ukuya kwiiyure, iziphumo ziya kuba ziiyure ezili-10. Nangona kunjalo, ukuba uguqule i-10,000 milliseconds ukuya kwimizuzu, isiphumo siya kuba yimizuzu eli-10 kunye nemizuzwana engama-40.

var date = new Date(milliseconds);
var hh = date.getHours();
var mm = date.getMinutes();
var ss = date.getSeconds();

Le khowudi idala into entsha yomhla isebenzisa iimillisecond ezinikiweyo, emva koko ifumana iiyure, imizuzu, kunye nemizuzwana ukusuka kuloo nto yomhla.

Ixesha kunye neJavaScript

IJavaScript lulwimi lwenkqubo oluqhutywa kwisikhangeli. Yadalwa ngo-1995 nguBrendan Eich kwaye ngoku yenye yezona lwimi zidumileyo kwiwebhu.

Enye yezona zinto zibaluleke kakhulu kwiJavaScript kukukwazi kwayo ukuqhuba i-asynchronously. Oku kuthetha ukuba ikhowudi inokusebenza ngokuhambelanayo, enokwenza imisebenzi ngokukhawuleza. IJavaScript nayo inomhla kunye nethala leencwadi eyakhelwe-ngaphakathi, eyenza kube lula ukusebenza kunye nemihla kunye namaxesha.

Ukuguqulwa kwexesha

Kukho iindlela ezimbalwa zokuguqula ixesha kwiJavaScript. Eyona ndlela ixhaphakileyo kukusebenzisa into ethi Umhla.

var ngoku = Umhla omtsha (); // 12/5/2015 3:00 PM

Ungasebenzisa kwakhona i-Date.now () eyakhelwe-ngaphakathi umsebenzi.

var ngoku = Umhla.ngoku (); // 12/5/2015 3:00 PM
