最近和同事吹水时常以xh代指距下班时间还有多久，想了想干脆写一个组件。

window.offWork = () => {
    let time = new Date().toTimeString().substr(0, 8).split(":"),
        ms =
            (17 - +time[0]) * 60 * 60 * 1000 - +time[1] * 60 * 1000 - +time[2] * 1000,
        h = parseInt(ms / (60 * 1000 * 60)),
        min = parseInt((ms % (1000 * 60 * 60)) / (1000 * 60)),
        s = Math.floor((ms % (1000 * 60)) / 1000);
    return "距下班还有:" + h + "小时" + min + "分钟" + s + "秒";
};

计算时间很简单，分别计算时分秒就行。写代码写麻了就控制台来个offWork()。

                s = Math.floor((ms % (1000 * 60)) / 1000);
            return "还有:" + h + "小时" + min + "分钟" + s + "秒";
        },
    },
};
</script>

<style></style>

vue组件形式，可以挂个窗口看。
