CocosCreator3.x开发笔记3:时间相关

秒转换为时分秒

private formatTime(totalSeconds: number): string
    { 
        let hours: number = this.rounding((totalSeconds / 3600));
        let hh: string = (hours < 10 ? "0" + hours : hours).toString();
        let minutes: number = this.rounding((totalSeconds - hours * 3600) / 60);
        let mm: string = minutes < 10 ? "0" + minutes : minutes.toString();
        let seconds: number = this.rounding(totalSeconds - hours * 3600 - minutes * 60);
        let ss: string = seconds < 10 ? "0" + seconds : seconds.toString();
        let num: string = hh + ":" + mm + ":" + ss;
        return num;
    }
    private rounding(num: number): number
    { 
        return Math.floor(num);
    }

获取时间戳

/*** 时间戳换算日期* */
    formatDateTimeBySelf(): string {
        var date = new Date();
        // date.setTime(timeStamp * 1000);
        let y = date.getFullYear();
        let m = date.getMonth() + 1;//月份是0-11
        let mS = m < 10 ? ('0' + m.toString()) : m.toString();
        let d = date.getDate();
        let dS = d < 10 ? ('0' + d.toString()) : d.toString();
        let h = date.getHours();
        let hS = h < 10 ? ('0' + h.toString()) : h.toString();
        var minute = date.getMinutes();
        var second = date.getSeconds();
        let minuteS = minute < 10 ? ('0' + minute) : minute;
        let secondS = second < 10 ? ('0' + second) : second;
        return y + '-' + mS + '-' + dS + ' ' + hS + ':' + minuteS + ':' + secondS;
    }

number转年月日

 formatDateTimeBySelf(saveTimeN: number): string {
        let date =  new Date(saveTimeN)
        // date.setTime(timeStamp * 1000);
        let y = date.getFullYear();
        let m = date.getMonth() + 1;//月份是0-11
        let mS = m < 10 ? ('0' + m.toString()) : m.toString();
        let d = date.getDate();
        let dS = d < 10 ? ('0' + d.toString()) : d.toString();
        let h = date.getHours();
        let hS = h < 10 ? ('0' + h.toString()) : h.toString();
        var minute = date.getMinutes();
        var second = date.getSeconds();
        let minuteS = minute < 10 ? ('0' + minute) : minute;
        let secondS = second < 10 ? ('0' + second) : second;
        return y + '-' + mS + '-' + dS + ' ' + hS + ':' + minuteS + ':' + secondS;
    }
