<!doctype html> <html lang="en"> <head> <meta charset="UTF-8" /> <title></title> <script src="js/jquery-1.12.2.js"></script> <script> var pre='css/'; $(function(){ if(!window.sessionStorage.getItem('style') || window.sessionStorage.getItem('style')==='') { $('#link').attr('href',pre+'link1.css'); $('#change').val('link1'); }else { $('#link').attr('href',pre+window.sessionStorage.getItem('style')); $('#change').val(window.sessionStorage.getItem('style')); } }) </script> <link rel="stylesheet" rev="stylesheet" id="link" type="text/css" media="all" href="" /> <script> var pre='css/'; $(function(){ $('#change').on('change',function(){ window.sessionStorage.setItem('style',this.value); location.reload(false); }) }) </script> </head> <body> <div></div> <select name="" id="change"> <option value="link1.css">link1</option> <option value="link2.css">link2</option> </select> </body> </html>
