myp-timetool/src/getDay.js

提供了格式化时间功能

//定义获取几天前几天后的函数
function getDay(day) {
    var today = new Date();
    var targetday_milliseconds = today.getTime() + 1000 * 60 * 60 * 24 * day;
    today.setTime(targetday_milliseconds); //注意，这行是关键代码
    var tYear = today.getFullYear();
    var tMonth = today.getMonth();
    var tDate = today.getDate();
    tMonth = doHandleMonth(tMonth + 1);
    tDate = doHandleMonth(tDate);
    return tYear + "-" + tMonth + "-" + tDate;
}

function doHandleMonth(month) {
    var m = month;
    if (month.toString().length == 1) {
        m = "0" + month;
    }
    return m;
}

module.exports = {
    getDay
}
