下面是一个例子：

<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body><script type="text/javascript">var i=localStorage.pagecount;if(i){localStorage.pagecount=Number(i)+1;}else{localStorage.pagecount=1;}document.write("local:"+localStorage.pagecount);var j=sessionStorage.pagecount;if(j){sessionStorage.get.pagecount=Number(j)+1;}else{sessionStorage.pagecount=1;}document.write("session:"+sessionStorage.pagecount);</script></body></html>

localStorage和sessionStorage 是window对象，他们都实现了Storage接口

interface Storage {  readonly attribute unsigned long length;  DOMString? key(unsigned long index);  getter DOMString getItem(DOMString key);  setter creator void setItem(DOMString key, DOMString value);  deleter void removeItem(DOMString key);  void clear();};
