给安知鱼主题添加倒计时卡片

1.在博客目录的 source 文件夹下创建_data文件夹并创建widget.yml文件内容如下

top:
  - class_name: card-countdown
    id_name: 
    name: 
    icon:
    html: |
      <div class="cd-count-left">
        <span class="cd-text">距离</span>
        <span class="cd-name" id="eventName"></span>
        <span class="cd-time" id="daysUntil"></span>
        <span class="cd-date" id="eventDate"></span>
      </div>
      <div id="countRight" class="cd-count-right"></div>

2.在 _config.anzhiyu.yml 主题配置文件的 inject 配置项的 bottom 中引入 JS 文件:

inject:
  bottom:
    - <script src="/static/countdown.js"></script>

3.在博客目录的 source 文件夹下创建 static 文件夹并创建然后创建countdown.js文件内容如下

const CountdownTimer = (() => {
    const config = {
        targetDate: "2025-01-29",
        targetName: "春节",
        units: {
            day: { text: "今日", unit: "小时" },
            week: { text: "本周", unit: "天" },
            month: { text: "本月", unit: "天" },
            year: { text: "本年", unit: "天" }
        }
    };

    const calculators = {
        day: () => {
            const hours = new Date().getHours();
            return {
                remaining: 24 - hours,
                percentage: (hours / 24) * 100
            };
        },
        week: () => {
            const day = new Date().getDay();
            const passed = day === 0 ? 6 : day - 1;
            return {
                remaining: 6 - passed,
                percentage: ((passed + 1) / 7) * 100
            };
        },
        month: () => {
            const now = new Date();
            const total = new Date(now.getFullYear(), now.getMonth() + 1, 0).getDate();
            const passed = now.getDate() - 1;
            return {
                remaining: total - passed,
                percentage: (passed / total) * 100
            };
        },
        year: () => {
            const now = new Date();
            const start = new Date(now.getFullYear(), 0, 1);
            const total = 365 + (now.getFullYear() % 4 === 0 ? 1 : 0);
            const passed = Math.floor((now - start) / 86400000);
            return {
                remaining: total - passed,
                percentage: (passed / total) * 100
            };
        }
    };

    function updateCountdown() {
        const elements = ['eventName', 'eventDate', 'daysUntil', 'countRight']
            .map(id => document.getElementById(id));
        
        if (elements.some(el => !el)) return;
        
        const [eventName, eventDate, daysUntil, countRight] = elements;
        const now = new Date();
        const target = new Date(config.targetDate);
        
        eventName.textContent = config.targetName;
        eventDate.textContent = config.targetDate;
        daysUntil.textContent = Math.round((target - now.setHours(0,0,0,0)) / 86400000);
        
        countRight.innerHTML = Object.entries(config.units)
            .map(([key, {text, unit}]) => {
                const {remaining, percentage} = calculators[key]();
                return `
                    <div class="cd-count-item">

                `;
            }).join('');
    }

    function injectStyles() {
        const styles = `

                display: flex;
                flex-direction: column;

            .cd-percentage,
            .cd-remaining {

                font-size: 12px;
                margin: 0 6px;
                transition: opacity 0.3s ease-in-out, transform 0.3s ease-in-out;

                opacity: 0;
                transform: translateX(10px);
            }
            .card-countdown .item-content:hover .cd-remaining {
                transform: translateX(0);
                opacity: 1;
            }
            .card-countdown .item-content:hover .cd-percentage {
                transform: translateX(-10px);
                opacity: 0;
            }
        `;

        const styleSheet = document.createElement("style");
        styleSheet.textContent = styles;
        document.head.appendChild(styleSheet);
    }

    let timer;
    const start = () => {
        injectStyles();
        updateCountdown();
        timer = setInterval(updateCountdown, 600000);
    };
    
    ['pjax:complete', 'DOMContentLoaded'].forEach(event => document.addEventListener(event, start));
    document.addEventListener('pjax:send', () => timer && clearInterval(timer));
    
    return { start, stop: () => timer && clearInterval(timer) };
})();

4. 然后修改日期就实现了倒计时

const config = {
    targetDate: "2025-01-29", // 目标日期
    targetName: "春节", // 名称
    ...
}
