日期格式化
第一個(gè)參數(shù)傳入標(biāo)準(zhǔn)時(shí)間
第二個(gè)參數(shù)傳入格式例如： 'yyyy-MM-DD' 'yyyy-MM-DD HH:mm:ss' 'HH:mm:ss' 'getDay'
function formatDate(date,format) {
let myyear = date.getFullYear();
let mymonth = date.getMonth() + 1;
let myday = date.getDate();
let myHours = date.getHours()
let myMinutes = date.getMinutes()
let mySeconds = date.getSeconds()
if (mymonth < 10) {
mymonth = "0" + mymonth;
}
if (myweekday < 10) {
myweekday = "0" + myweekday;
}
if (myHours < 10) {
myHours = "0" + myHours;
}
if (myMinutes < 10) {
myMinutes = "0" + myMinutes;
}
if (mySeconds < 10) {
mySeconds = "0" + mySeconds;
}
let dayNames = ["星期日","星期一","星期二","星期三","星期四","星期五","星期六"]
let weekday = dayNames[date.getDay()]
switch(format){
case 'yyyy-MM-DD' : return (myyear + "-" + mymonth + "-" + myweekday);
break;
case 'yyyy-MM-DD HH:mm:ss' : return (myyear + "-" + mymonth + "-" + myweekday + " " + myHours + ":" + myMinutes + ":" + mySeconds);
break;
case 'HH:mm:ss' : return (myHours + ":" + myMinutes + ":" + mySeconds);
break;
case 'getDay' : return weekday;
break
}
}
export { formatDate }
組件中(例如)：
import { formatDate } from '../config/DateFormatter'
formatDate(new Date() , 'HH:mm:ss')
