时间操作

JavaScript

var date = new Date()

function showTime(d){
    console.log(d.getFullYear() + '-' + (d.getMonth() + 1) + '-' + d.getDate() + ' ' + 
        d.getHours() + ':' + d.getMinutes() + ':' + d.getSeconds());
}

showTime(date);

//两位对齐 不足两位补0
function formatTime(d){
    function format(n){
        let tmp = n.toString();
        return tmp.length === 1 ? '0' + tmp : tmp;
    }
    return d.getFullYear() + '-' + format(d.getMonth() + 1) + '-' + format(d.getDate()) + ' ' +
        format(d.getHours()) + ':' + format(d.getMinutes()) + ':' + format(d.getSeconds());
}

function addYear(n,_d) {
    let d = _d?_d:new Date();
    d.setFullYear(d.getFullYear()+ n);
    return d;
}

function addMonth(n,_d) {
    let d = _d?_d:new Date();
    d.setMonth(d.getMonth()+ n);
    return d;
}

function addDay(n,_d){
    let d = _d?_d:new Date();
    d.setDate(d.getDate()+ n);
    return d;
}

function addSecond(n,_d) {
    let d = _d?_d:new Date();
    d.setSeconds(d.getSeconds() + n);
    return d;
}

showTime(addYear(1));

时间分割函数设计：

export const splitTime = t => {
    const f = s => {
        return s.toString().padStart(2, '0')
    }
    let d = new Date(t * 1000)
    let year = d.getFullYear().toString()
    let month = f(d.getMonth()+1)
    let date = f(d.getDate())
    let hour = f(d.getHours())
    let minute = f(d.getMinutes())
    let second = f(d.getSeconds())
    return {year, month, date, hour, minute, second}
}
