貼文討論:求助我要做一個計時器小程序



``` var time_val; var go_timer; var stop_time = 0; function add_zero(num, digit) { let numString = String(num) while (numString.length < digit) { numString = "0" + numString } return numString }

go_timer = new Date(); time_val = setInterval(() => { let temp_timer = new Date().getTime() - go_timer.getTime(); let day = add_zero(Math.floor(temp_timer / 1000 / 60 / 60 / 24), 2); let hours = add_zero(Math.floor(temp_timer / 1000 / 60 / 60) % 24, 2); let minutes = add_zero(Math.floor(temp_timer / 1000 / 60) % 60, 2); let seconds = add_zero(Math.floor(temp_timer / 1000 % 60), 2); let milliseconds = add_zero(temp_timer % 1000, 3); var timers = [day, hours, minutes, seconds, milliseconds]; console.log(timers[0] + "天\n" + timers[1] + "時\n" + timers[2] + "分\n" + timers[3] + "秒\n" + timers[4] + "毫秒"); }, 1)
