1.处理当前时间前后的日期范围 2.处理日期格式

Month(month) {//处理当前时间前后的日期范围
    var time = new Date();
    time.setDate(time.getDate());//获取Day天后的日期
    var y = time.getFullYear();
    var m;
    if (time.getMonth() + month + 1>12){
        y = y+1;
        m = time.getMonth() + month - 11;//获取当前月份的日期 d
    }else{
        m = time.getMonth() + month + 1;//获取当前月份的日期 d
    }
    var d = time.getDate();
    return y + "-" + m + "-" + d;
}

getdate(now) {//处理日期格式

    let y = now.getFullYear();
    let m = now.getMonth() + 1;
    let d = now.getDate();
    return y + "-" + (m < 10 ? "0" + m : m) + "-" + (d < 10 ? "0" + d : d) + " " + now.toTimeString().substr(0, 5);
