 1.全局引用

import publicUtils from '@/util/publicUtil';
Vue.prototype.publicUtils = publicUtils;

2.工具类编写

export default {
    getSize(val) {
        var KB = val / 1024;
        var MB = KB / 1024;
        if (MB < 1024) {
            return `${MB.toFixed(2)}MB`;
        } else {
            let GB = MB / 1024;
            if (GB < 1024) {
                return `${GB.toFixed(2)}GB`;
            } else {
                return `${(GB / 1024).toFixed(2)}TB`;
            }
        }
    },

    getProportion(width, height) {
        if (height && width) {
            return `${width} * ${height}`
        }
        return ``;
    },

    padZero(number) {
        return number < 10 ? '0' + number : number;
    },

    timeFormat(seconds) {
        var hours = Math.floor(seconds / 3600);
        var minutes = Math.floor((seconds % 3600) / 60);
        var remainingSeconds = seconds % 60;

        // 在小时、分钟、秒数小于10时，在前面补零
        var formattedHours = this.padZero(hours);
        var formattedMinutes = this.padZero(minutes);
        var formattedSeconds = this.padZero(remainingSeconds);

        return formattedHours + ':' + formattedMinutes + ':' + formattedSeconds;
    }
}
