【JS工具方法】-时间操作篇

当前时间

export const nowTime = () => {
    const now = new Date();
    const year = now.getFullYear();
    const month = now.getMonth();
    const date = now.getDate() >= 10 ? now.getDate() : ('0' + now.getDate());
    const hour = now.getHours() >= 10 ? now.getHours() : ('0' + now.getHours());
    const miu = now.getMinutes() >= 10 ? now.getMinutes() : ('0' + now.getMinutes());
    const sec = now.getSeconds() >= 10 ? now.getSeconds() : ('0' + now.getSeconds());
    return +year + "年" + (month + 1) + "月" + date + "日 " + hour + ":" + miu + ":" + sec;
}

格式化时间

export const dateFormater = (formater, time) => {
    let date = time ? new Date(time) : new Date(),
        Y = date.getFullYear() + '',
        M = date.getMonth() + 1,
        D = date.getDate(),
        H = date.getHours(),
        m = date.getMinutes(),
        s = date.getSeconds();
    return formater.replace(/YYYY|yyyy/g, Y)
        .replace(/YY|yy/g, Y.substr(2, 2))
        .replace(/MM/g,(M<10 ? '0' : '') + M)
        .replace(/DD/g,(D<10 ? '0' : '') + D)
        .replace(/HH|hh/g,(H<10 ? '0' : '') + H)
        .replace(/mm/g,(m<10 ? '0' : '') + m)
        .replace(/ss/g,(s<10 ? '0' : '') + s)
}
// dateFormater('YYYY-MM-DD HH:mm:ss')
// dateFormater('YYYYMMDDHHmmss')
