sessionStorage.setItem('xxx',{}), get the result "[object Object]"
How Save other types?

Answer 2

sessionStorage和localStorage只能存字符串，针对对象需要存储storageIf you want, you can serialize it to achieve the effect:

var obj = {};
sessionStorage.setItem('xxx', JSON.stringify(obj)); //序列化
obj = JSON.parse(sessionStorage.setItem('xxx')); //这时候需要反序列化一下

Reference:

• localStorage stores JSON objects

• JS operation JSON

Answer 3

webStorage itself can store non-strings, but no browser has implemented it yet
