localstorage存取json

本篇简单介绍如何从localstorage中存取json数据。
将json数据存入localstorage前，需要使用JSON.stringify将其转化成字符串

var students = {        liyang: {            name: "liyang",            age: 17        },        lilei: {            name: "lilei",            age: 18        }    } //要存储的JSON对象   students = JSON.stringify(students);//将JSON对象转化成字符串  localStorage.setItem("students",students);//用localStorage保存转化好的的字符串

从localstorage中获取数据字符串，使用JSON.parse将其转化成json

var students = localStorage.getItem("students"); //取回students变量students = JSON.parse(students);//把字符串转换成JSON对象
