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cookie14 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cookie38 this.unset = function(name, path, domain, secure) {39 this.set(name, '', new Date(0), path, domain, secure );40 };41 42 // 设置多值cookie43 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cookie53 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cookie64 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cookie70 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cookie75 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 })();
