如何让我的chrome扩展记住切换开关或其他操作？

{
  "manifest_version": 2,
  "name": "My Extension",
  "version": "1.0",
  "permissions": [
    "storage"
  ],
  "background": {
    "scripts": ["background.js"],
    "persistent": false
  },
  "browser_action": {
    "default_popup": "popup.html"
  },
  "icons": {
    "16": "icon16.png",
    "48": "icon48.png",
    "128": "icon128.png"
  }
}

// 存储开关状态
function saveSwitchState(state) {
  chrome.storage.sync.set({ switchState: state }, function() {
    console.log('开关状态已保存');
  });
}

// 读取开关状态
function getSwitchState(callback) {
  chrome.storage.sync.get('switchState', function(result) {
    var state = result.switchState;
    if (state === undefined) {
      state = true; // 默认开启状态
    }
    callback(state);
  });
}

// 切换开关状态
function toggleSwitch() {
  getSwitchState(function(state) {
    var newState = !state;
    saveSwitchState(newState);
    // 执行开关切换的其他操作
    // ...
  });
}
