js设置、获取单值cookie和多值cookie，代码如下：

 1 var CookieUtil = (function () {
 2     var Cookie = function () {
 3         // 获取单值cookie
 4         this.get = function(name) {
 5             var start = document.cookie.indexOf(encodeURIComponent(name)) ;
 6             var end = document.cookie.indexOf(';', start) ;
 7             if(end == -1) {
 8                 end = document.cookie.length;
 9             }
10             return decodeURIComponent(document.cookie.substring(start+name.length+1,end));
11         };
12         
13         // 设置单值cookie
14         this.set = function(name, value, expires, path, domain, secure) {
15             var cookieText = encodeURIComponent(name) + "=" + encodeURIComponent(value);
16             // 设置默认过期时间为七天
17             if(expires == undefined) {
18                 var date = new Date();
19                 date.setTime(date.getTime() + 7*24*60*60*1000);
20                 expires = date ;
21             }
22             if(expires instanceof Date) {
23                 cookieText += "; expires=" + expires.toGMTString();
24             }
25             if(path != undefined) {
26                 cookieText += "; path=" + path;
27             }
28             if(domain != undefined) {
29                 cookieText += "; domain" + domain;
30             }
31             if(secure != undefined) {
32                 cookieText += "; secure";
33             }
34             document.cookie = cookieText;
35         };
36         
37         // 清除单值cookie
38         this.unset = function(name, path, domain, secure) {
39             this.set(name, '', new Date(0), path, domain, secure );
40         };
41         
42         // 设置多值cookie
43         this.setAll = function(name, subCookies, expires, path, domain, secure) {
44             var cookieText = ";" + encodeURIComponent(name) + "=",
45             arr = new Array();
46             for(var attr in subCookies) {
47                 arr.push([encodeURIComponent(attr)] + ":" + encodeURIComponent(subCookies[attr]));
48             } 
49             this.set(name, arr.join('&'), expires, path, domain, secure);
50         };
51         
52         // 获取多值cookie
53         this.getAll = function(name) {
54             var obj = {};
55             var arr = this.get(name).split('&');
56             for(var i = 0, len = arr.length; i < len; i++) {
57                 var tmpArr = arr[i].split(':');
58                 obj[decodeURIComponent(tmpArr[0])] = decodeURIComponent(tmpArr[1]);
59             }
60             return obj;
61         };
62         
63         // 获取多值cookie的子cookie
64         this.getSub = function(name, subname) {
65             var obj = this.getAll(name);
66             return obj[subname];
67         };
68         
69         // 清除指定的多值cookie
70         this.unsetAll = function(name,path,domain,secure) {
71             this.unset(name, '', new Date(0), path, domain, secure);
72         };
73         
74         // 清除指定多值cookie的子cookie
75         this.unsetSub = function(name, subname,path, domain, secure) {
76             var obj = this.getAll(name);
77             delete obj[subname];
78             this.setAll(name, obj, null, path, domain, secure);
79         };
80     };
81     return new Cookie();
82 })();
