localStorage存储方法

localStorage存储方法

localStorage.name = localStorage["name"]='vanida'；

localStorage.setItem("name","vanida");//这三种设置值方式是一样的；

 

localStorage获取值方法

var name=localStorage.name = localStorage["name"] = localStorage.setItem("name");//这三种取值方式是一样的；

 

localStorage清值方法

localStorage.removeItem("name");或者localStorage.name＝'';//清除name的值

 

localStorage只能存储字符串，如果需要存储对象，首先要转化为字符串。利用JSON.stringify()；
例子：
var person = {name:"vanida","sex":"girl","age":25};localStorage.setItem("person",JSON.stringify(person));
// localStorage.person="{"name":"vanida","sex":"girl","age":25}"

要特别注意JSON.stringify()中不要忘了“i”,stringify而不是stringfy。已经被坑了好几次！
然后取出person的对象你可以用JSON.parse();
例子：
person = JSON.parse(storage.getItem("person"));
// {name: "vanida", sex: "girl", age: 25}
