sessions tor log 永久 用法 utf oca 一個 style
localStorage和sessionStorage的區別:
localStorage(本地存儲) 大(5M)/cookie(4K) 1.大：1280倍 2.localStorage不會被發往服務器 3.方便 localStorage/sessionStorage localStorage 永久存儲 sessionStorage 會話期存儲（瀏覽器關了就沒了） localStorage的用法跟json一模一樣 localStorage.a=xxx 設置 localStorage.a 讀取 delete localStorage.a 刪掉 for in 遍歷 sessionStorage用法和localStorage一模一樣
1.存一個對象進localStorage
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title></title> <script> let obj={ name: ‘blue‘, age: 18 }; localStorage.a=JSON.stringify(obj); let obj2=JSON.parse(localStorage.a); alert(obj2.name);</script> </head> <body> </body> </html>
