设置管理的重要性

应用设置允许用户根据自己的需求定制应用。通过Cordova框架与OpenHarmony的配置管理能力，我们可以构建一个完整的设置系统。本文将介绍如何实现这一功能。

设置数据模型

class AppSettings {
  constructor(userId) {
    this.userId = userId;
    this.settings = {
      profile: {
        name: '',
        age: 0,
        gender: 'male',
        weight: 0,
        height: 0,
        activityLevel: 'moderate'
      },
      notifications: {
        enabled: true,
        workoutReminders: true,
        goalReminders: true,
        socialNotifications: true,
        soundEnabled: true,
        vibrationEnabled: true
      },
      privacy: {
        profileVisibility: 'public',
        workoutVisibility: 'friends',
        shareData: false,
        allowTracking: true
      },
      display: {
        theme: 'light',
        language: 'zh-CN',
        unitSystem: 'metric',
        dateFormat: 'YYYY-MM-DD'
      },
      data: {
        autoBackup: true,
        backupFrequency: 'weekly',
        cloudSync: true
      }
    };
  }
  
  updateSetting(path, value) {
    const keys = path.split('.');
    let obj = this.settings;
    
    for (let i = 0; i < keys.length - 1; i++) {
      obj = obj[keys[i]];
    }
    
    obj[keys[keys.length - 1]] = value;
    this.saveSetting(path, value);
  }
  
  getSetting(path) {
    const keys = path.split('.');
    let obj = this.settings;
    
    for (const key of keys) {
      obj = obj[key];
    }
    
    return obj;
  }
}

AppSettings类管理应用的所有设置。通过updateSetting和getSetting方法，用户可以修改和获取设置。

个人资料设置

function renderProfileSettings(settings) {
  const container = document.getElementById('profile-settings');
  
  const html = `
    <div class="settings-section">
      <h3>个人资料</h3>
      <div class="setting-item">
        <label>姓名</label>
        <input type="text" value="${settings.profile.name}" 
               onchange="updateSetting('profile.name', this.value)">
      </div>
      <div class="setting-item">
        <label>年龄</label>
        <input type="number" value="${settings.profile.age}" 
               onchange="updateSetting('profile.age', this.value)">
      </div>
      <div class="setting-item">
        <label>性别</label>
        <select onchange="updateSetting('profile.gender', this.value)">
          <option value="male" ${settings.profile.gender === 'male' ? 'selected' : ''}>男</option>
          <option value="female" ${settings.profile.gender === 'female' ? 'selected' : ''}>女</option>
        </select>
      </div>
      <div class="setting-item">
        <label>体重(kg)</label>
        <input type="number" value="${settings.profile.weight}" 
               onchange="updateSetting('profile.weight', this.value)">
      </div>
      <div class="setting-item">
        <label>身高(cm)</label>
        <input type="number" value="${settings.profile.height}" 
               onchange="updateSetting('profile.height', this.value)">
      </div>
      <div class="setting-item">
        <label>活动水平</label>
        <select onchange="updateSetting('profile.activityLevel', this.value)">
          <option value="sedentary" ${settings.profile.activityLevel === 'sedentary' ? 'selected' : ''}>久坐</option>
          <option value="light" ${settings.profile.activityLevel === 'light' ? 'selected' : ''}>轻度</option>
          <option value="moderate" ${settings.profile.activityLevel === 'moderate' ? 'selected' : ''}>中度</option>

          <option value="veryActive" ${settings.profile.activityLevel === 'veryActive' ? 'selected' : ''}>非常活跃</option>
        </select>
      </div>
    </div>
  `;
  
  container.innerHTML = html;
}

个人资料设置允许用户编辑自己的基本信息。这个函数创建了一个表单，用户可以修改个人资料。

通知设置

function renderNotificationSettings(settings) {
  const container = document.getElementById('notification-settings');
  
  const html = `
    <div class="settings-section">
      <h3>通知设置</h3>
      <div class="setting-item">
        <label>启用通知</label>
        <input type="checkbox" ${settings.notifications.enabled ? 'checked' : ''} 
               onchange="updateSetting('notifications.enabled', this.checked)">
      </div>
      <div class="setting-item">
        <label>运动提醒</label>
        <input type="checkbox" ${settings.notifications.workoutReminders ? 'checked' : ''} 
               onchange="updateSetting('notifications.workoutReminders', this.checked)">
      </div>
      <div class="setting-item">
        <label>目标提醒</label>
        <input type="checkbox" ${settings.notifications.goalReminders ? 'checked' : ''} 
               onchange="updateSetting('notifications.goalReminders', this.checked)">
      </div>
      <div class="setting-item">
        <label>社交通知</label>
        <input type="checkbox" ${settings.notifications.socialNotifications ? 'checked' : ''} 
               onchange="updateSetting('notifications.socialNotifications', this.checked)">
      </div>
      <div class="setting-item">
        <label>声音</label>
        <input type="checkbox" ${settings.notifications.soundEnabled ? 'checked' : ''} 
               onchange="updateSetting('notifications.soundEnabled', this.checked)">
      </div>
      <div class="setting-item">
        <label>振动</label>
        <input type="checkbox" ${settings.notifications.vibrationEnabled ? 'checked' : ''} 
               onchange="updateSetting('notifications.vibrationEnabled', this.checked)">

        <label>个人资料可见性</label>
        <select onchange="updateSetting('privacy.profileVisibility', this.value)">
          <option value="public" ${settings.privacy.profileVisibility === 'public' ? 'selected' : ''}>公开</option>
          <option value="friends" ${settings.privacy.profileVisibility === 'friends' ? 'selected' : ''}>仅朋友</option>
          <option value="private" ${settings.privacy.profileVisibility === 'private' ? 'selected' : ''}>私密</option>
        </select>
