[JavaScript]localStorage对象

// Key = 键名 Value = 值
localStorage.setItem(Key,Value); //存储
localStorage.Key = Value; //同等于上面的方法
localStorage[Key] = Value;

localStorage.getItem(Key); //获取
localStorage.Key; 
localStorage[Key];

localStorage.removeItem(Key); //删除

localStorage.clear(); //清空缓存
// 使用localStorage保存对象的方法
function saveObject(key,obj){
 if(typeof(obj) == ‘object‘){
  localStorage.setItem(key,JSON.stringify(obj));
 }else{
  localStorage.setItem(key,obj);
 }
}
// 使用localStorage获取储存的对象方法
function getObject(key){
 obj = localStorage.getItem(key);
 return JSON.parse(obj);
}
//用法:
saveObject("test",{name:‘Himpq‘,age:20,sex:‘男‘});
alert(getObject("test").name);//输出： Himpq
