封装localstorage为对象 js

export const LocalStorageManager = {recordKey: "Record",// 获取本地存储中的值get(key) {try {const value = localStorage.getItem(key);if (value === null || value === undefined || value === "") {return null;}return JSON.parse(localStorage.getItem(key));} catch (err) {return null;}},// 设置本地存储中的值set(key, value) {return localStorage.setItem(key, JSON.stringify(value));},// 删除本地存储中的值remove(key) {return localStorage.removeItem(key);},// 清空本地存储clear() {return localStorage.clear();},// 获取 localsotrage 中以某个字符开头的所有数据// const data = LocalStorageManager.getDataStartingWith(LocalStorageManager.recordKey);getDataStartingWith(prefix) {let data = {};for (let key in localStorage) {if (key.startsWith(prefix)) {data[key] = JSON.parse(localStorage.getItem(key));}}return data;}
};
