Value; / / stores the value in the local browser sessionStorage.setItem ("name", name); sessionStorage.setItem ("pwd", pwd) Alert ("chenggong!"); localStorage.setItem ("name1", name); localStorage.setItem ("pwd1", pwd) } function my2 () {/ / clear the data stored in the browser localStorage.clear () LocalStorage.removeItem ("name1"); sessionStorage.removeItem ("name"); sessionStorage.clear () / / get the values stored in the local browser var name = sessionStorage.getItem ("name"); var pwd = sessionStorage.getItem ("pwd"); alert ("name:" + name+ "--pwd:" + pwd) } this is the end of the article on "how to use sessionStorage and localStorage".
