cookie.js文件
偶尔发现ExtJS中有操作cookie的js方法，拿来给大家分享下。 var Cookies = {}; Cookies.set = function(name, value){ var argv = arguments; var argc = arguments.length; var expires = (argc > 2) ? argv[2] : null; var path = (argc > 3) ? argv[3] : '/'; var domain = (argc > 4) ? argv[4] : null; var secure = (argc > 5) ? argv[5] : false; document.cookie = name + "=" + escape (value) + ((expires == null) ? "" : ("; expires=" + expires.toGMTString())) + ((path == null) ? "" : ("; path=" + path)) + ((domain == null) ? "" : ("; domain=" + domain)) + ((secure == true) ? "; secure" : ""); }; Cookies.get = function(name){ var arg = name + "="; var alen = arg.length; var clen = document.cookie.length; var i = 0; var j = 0; while(i < clen){ j = i + alen; if (document.cookie.substring(i, j) == arg) return Cookies.getCookieVal(j); i = document.cookie.indexOf(" ", i) + 1; if(i == 0) break; } return null; }; Cookies.clear = function(name) { if(Cookies.get(name)){ document.cookie = name + "=" + "; expires=Thu, 01-Jan-70 00:00:01 GMT"; } }; Cookies.getCookieVal = function(offset){ var endstr = document.cookie.indexOf(";", offset); if(endstr == -1){ endstr = document.cookie.length; } return unescape(document.cookie.substring(offset, endstr)); };
示例：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>OperateCookie.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"> <script type="text/javascript" src="cookie.js"></script> <script type="text/javascript"> function set() { Cookies.set("name", "tom"); Cookies.set("sex", "男"); } function get() { alert(Cookies.get("name")); alert(Cookies.get("sex")); } function clear(s) { Cookies.clear(s); } </script> </head> <body> <input type="button" value=" set " onclick="set()"/> <input type="button" value=" get " onclick="get()"/> <input type="button" value=" clear sex " onclick="clear('sex')"/> <input type="button" value=" clear name " onclick="clear('name')"/> </body> </html>
