JavaScript设置、获取、清除单值和多值cookie的方法_javascript技巧

废话不多说了，直接给大家贴代码了。

具体代码如下：

var CookieUtil = (function () {
   var Cookie = function () {
     // 获取单值cookie
     this.get = function(name) {
       var start = document.cookie.indexOf(encodeURIComponent(name)) ;
       var end = document.cookie.indexOf(';', start) ;
       if(end == -) {
         end = document.cookie.length;
       }
       return decodeURIComponent(document.cookie.substring(start+name.length+,end));
     };
     // 设置单值cookie
     this.set = function(name, value, expires, path, domain, secure) {
       var cookieText = encodeURIComponent(name) + "=" + encodeURIComponent(value);
       // 设置默认过期时间为七天
       if(expires == undefined) {
         var date = new Date();
         date.setTime(date.getTime() + ****);
         expires = date ;
       }
       if(expires instanceof Date) {
         cookieText += "; expires=" + expires.toGMTString();
       }
       if(path != undefined) {
         cookieText += "; path=" + path;
       }
       if(domain != undefined) {
         cookieText += "; domain" + domain;
       }
       if(secure != undefined) {
         cookieText += "; secure";
       }
       document.cookie = cookieText;
     };
     // 清除单值cookie
     this.unset = function(name, path, domain, secure) {
       this.set(name, '', new Date(), path, domain, secure );
     };
     // 设置多值cookie
     this.setAll = function(name, subCookies, expires, path, domain, secure) {
       var cookieText = ";" + encodeURIComponent(name) + "=",
       arr = new Array();
       for(var attr in subCookies) {
         arr.push([encodeURIComponent(attr)] + ":" + encodeURIComponent(subCookies[attr]));
       } 
       this.set(name, arr.join('&'), expires, path, domain, secure);
     };
     // 获取多值cookie
     this.getAll = function(name) {
       var obj = {};
       var arr = this.get(name).split('&');
       for(var i = , len = arr.length; i
