HTML5 学习之web存储localStorage
localStorage 实例：<!DOCTYPE><html><head> <title>test2.html</title> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="this is my page"> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <!--<link rel="stylesheet" type="text/css" href="./styles.css">--><script type="text/javascript">function submitL(obj){var lname=document.getElementById("logname");if(lname.value=='test'){localStorage.lname=lname.value;}var ln=document.getElementById("msg");ln.innerHTML=localStorage.lname;}</script></head> <body> 页面计数器<br /> localStorage <br/> <input id="logname" value="" /> <input type="button" value="submit" > <div id="msg"> </div> <div id="numcount"> </div> <script type="text/javascript"> if(localStorage.pagecount){ localStorage.pagecount=Number(localStorage.pagecount)+1; }else{ localStorage.pagecount=1; } document.write("Visit: "+localStorage.pagecount+" times"); </script> </body></html>http://www.w3school.com.cn上说localStorage 方法存储的数据没有时间限制。第二天、第二周或下一年之后，数据依然可用。本人小小测试了一下，当我们将数据存储下来后，关闭浏览器再次打开数据还能取出来，但是当你清除掉cookie时它就木有啦，木有啦！这个实际上还是和cookie相关的。其次，本人还发现一个问题是，从history访问页面时，计数器同样会计数。
