Cordova与OpenHarmony养护技巧分享

欢迎大家加入开源鸿蒙跨平台开发者社区，一起共建开源鸿蒙跨平台生态。

养护技巧系统概述

养护技巧系统为用户提供了专业的植物养护建议和技巧。在Cordova框架与OpenHarmony系统的结合下，我们需要实现一个完整的技巧库系统，包括技巧内容管理、搜索和推荐功能。

养护技巧数据模型

javascript 复制代码

class CareTip {
    constructor(id, title, category, content, difficulty) {
        this.id = id;
        this.title = title;
        this.category = category; // 浇水、施肥、修剪等
        this.content = content;
        this.difficulty = difficulty; // easy, medium, hard
        this.createdDate = new Date();
        this.likes = 0;
        this.views = 0;
        this.author = '';
        this.tags = [];
    }
}

class CareTipManager {
    constructor() {
        this.tips = [];
        this.initDefaultTips();
        this.loadFromStorage();
    }
    
    initDefaultTips() {
        this.tips = [
            new CareTip('tip_1', '如何判断植物是否需要浇水', '浇水', 
                '检查土壤表面，如果干燥则需要浇水。也可以用手指插入土壤2厘米深处，如果感觉干燥则浇水。', 'easy'),
            new CareTip('tip_2', '施肥的最佳时间', '施肥', 
                '通常在生长季节（春夏）每2-4周施肥一次。冬季减少施肥频率。', 'easy'),
            new CareTip('tip_3', '修剪技巧', '修剪', 
                '使用锋利的剪刀，在叶节下方修剪。移除枯死或病弱的枝条。', 'medium')
        ];
    }
    
    searchTips(keyword) {
        return this.tips.filter(tip => 
            tip.title.toLowerCase().includes(keyword.toLowerCase()) ||
            tip.content.toLowerCase().includes(keyword.toLowerCase())
        );
    }
    
    getTipsByCategory(category) {
        return this.tips.filter(tip => tip.category === category);
    }
    
    getTipsByDifficulty(difficulty) {
        return this.tips.filter(tip => tip.difficulty === difficulty);
    }
}

这个养护技巧数据模型定义了CareTip和CareTipManager类。

与OpenHarmony的集成

javascript 复制代码

function loadCareTipsFromServer() {
    cordova.exec(
        function(result) {
            console.log("养护技巧已加载");
            careTipManager.tips = result;
            renderCareTips();
        },
        function(error) {
            console.error("加载失败:", error);
        },
        "NetworkPlugin",
        "getCareTips",
        [{
            limit: 50
        }]
    );
}

这段代码展示了如何与OpenHarmony的网络服务集成，加载养护技巧。

技巧列表展示

javascript 复制代码

function renderCareTips() {
    const container = document.getElementById('page-container');
    container.innerHTML = `
        <div class="care-tips">
            <h2>养护技巧</h2>
            <div class="tips-filters">
                <select id="category-filter" onchange="filterTipsByCategory()">
                    <option value="">所有分类</option>
                    <option value="浇水">浇水</option>
                    <option value="施肥">施肥</option>
                    <option value="修剪">修剪</option>
                    <option value="换盆">换盆</option>
                </select>
                <select id="difficulty-filter" onchange="filterTipsByDifficulty()">
                    <option value="">所有难度</option>
                    <option value="easy">简单</option>
                    <option value="medium">中等</option>
                    <option value="hard">困难</option>
                </select>
                <input type="text" id="tips-search" placeholder="搜索技巧...">
                <button onclick="searchTips()">🔍 搜索</button>
            </div>
        </div>
    `;
    
    const tipsList = document.createElement('div');
    tipsList.className = 'tips-list';
    
    careTipManager.tips.forEach(tip => {
        const tipCard = document.createElement('div');
        tipCard.className = `tip-card difficulty-${tip.difficulty}`;
        
        tipCard.innerHTML = `
            <div class="tip-header">
                <h3>${tip.title}</h3>
                <span class="tip-category">${tip.category}</span>
            </div>
            <p class="tip-content">${tip.content}</p>
            <div class="tip-tags">
                ${tip.tags.map(tag => `<span class="tag">#${tag}</span>`).join('')}
            </div>
            <div class="tip-stats">
                <span>👁️ ${tip.views}</span>
                <span>👍 ${tip.likes}</span>
            </div>
            <div class="tip-actions">
                <button onclick="likeTip('${tip.id}')">👍 赞</button>
                <button onclick="shareTip('${tip.id}')">📤 分享</button>
            </div>
        `;
        
        tipsList.appendChild(tipCard);
    });
    
    container.appendChild(tipsList);
}

这个函数负责渲染养护技巧列表。

技巧搜索和筛选

javascript 复制代码

function filterTipsByCategory() {
    const category = document.getElementById('category-filter').value;
    const tips = category ? careTipManager.getTipsByCategory(category) : careTipManager.tips;
    renderFilteredTips(tips);
}

function filterTipsByDifficulty() {
    const difficulty = document.getElementById('difficulty-filter').value;
    const tips = difficulty ? careTipManager.getTipsByDifficulty(difficulty) : careTipManager.tips;
    renderFilteredTips(tips);
}

function searchTips() {
    const keyword = document.getElementById('tips-search').value;
    if (!keyword) {
        renderCareTips();
        return;
    }
    
    const results = careTipManager.searchTips(keyword);
    renderFilteredTips(results);
}

function renderFilteredTips(tips) {
    const container = document.getElementById('page-container');
    container.innerHTML = `
        <div class="filtered-tips">
            <h2>搜索结果</h2>
            <p>找到 ${tips.length} 个技巧</p>
        </div>
    `;
    
    if (tips.length === 0) {
        container.innerHTML += '<p class="empty-message">未找到匹配的技巧</p>';
        return;
    }
    
    const tipsList = document.createElement('div');
    tipsList.className = 'tips-list';
    
    tips.forEach(tip => {
        const tipCard = document.createElement('div');
        tipCard.className = `tip-card difficulty-${tip.difficulty}`;
        
        tipCard.innerHTML = `
            <h3>${tip.title}</h3>
            <p>${tip.content}</p>
            <button onclick="likeTip('${tip.id}')">👍 赞 (${tip.likes})</button>
        `;
        
        tipsList.appendChild(tipCard);
    });
    
    container.appendChild(tipsList);
}

这段代码实现了技巧的搜索和筛选功能。

技巧推荐

javascript 复制代码

class CareTipRecommendation {
    constructor() {
        this.careTipManager = careTipManager;
    }
    
    getRecommendedTips(plantId) {
        const plant = plants.find(p => p.id === plantId);
        if (!plant) return [];
        
        const recommendations = [];
        
        // 根据植物健康状态推荐
        if (plant.health === 'warning') {
            recommendations.push(...this.careTipManager.getTipsByCategory('浇水'));
            recommendations.push(...this.careTipManager.getTipsByCategory('施肥'));
        }
        
        // 根据季节推荐
        const month = new Date().getMonth();
        if (month >= 5 && month <= 8) { // 夏季
            recommendations.push(...this.careTipManager.searchTips('浇水'));
        }
        
        return recommendations.slice(0, 5);
    }
    
    getTipsForBeginners() {
        return this.careTipManager.getTipsByDifficulty('easy');
    }
}

function renderRecommendedTips(plantId) {
    const recommendation = new CareTipRecommendation();
    const tips = recommendation.getRecommendedTips(plantId);
    
    const container = document.createElement('div');
    container.className = 'recommended-tips';
    container.innerHTML = '<h3>为您推荐</h3>';
    
    tips.forEach(tip => {
        const tipItem = document.createElement('div');
        tipItem.className = 'tip-item';
        tipItem.innerHTML = `
            <h4>${tip.title}</h4>
            <p>${tip.content.substring(0, 100)}...</p>
        `;
        container.appendChild(tipItem);
    });
    
    return container;
}

这段代码实现了技巧推荐功能。

技巧统计

javascript 复制代码

class CareTipStatistics {
    constructor() {
        this.careTipManager = careTipManager;
    }
    
    getTotalTips() {
        return this.careTipManager.tips.length;
    }
    
    getTipsByCategory() {
        const counts = {};
        
        this.careTipManager.tips.forEach(tip => {
            counts[tip.category] = (counts[tip.category] || 0) + 1;
        });
        
        return counts;
    }
    
    getMostPopularTips(limit = 10) {
        return this.careTipManager.tips
            .sort((a, b) => b.likes - a.likes)
            .slice(0, limit);
    }
    
    getMostViewedTips(limit = 10) {
        return this.careTipManager.tips
            .sort((a, b) => b.views - a.views)
            .slice(0, limit);
    }
}

这个CareTipStatistics类提供了技巧的统计功能。

总结
