Question

formatTime: function (format = 'yyyyMMddhhmmss', time) {
        var formateArr = ['y', 'M', 'd', 'h', 'm', 's'];
        var returnArr = [];
        var time = time.replace(getRegExp('-', 'g'), '/');
        var date = getDate(time);
        returnArr.push(date.getFullYear());
        returnArr.push(date.getMonth() + 1);
        returnArr.push(date.getDate());

        returnArr.push(date.getHours());
        returnArr.push(date.getMinutes());
        returnArr.push(date.getSeconds());
        
        for (i = 0, l = returnArr.length; i < l; i++) {
            format = format.replace(getRegExp(formateArr[i] + '+'), returnArr[i]);
        }
        return format;
    }
