js cookie得到多个cookie中的单个cookie对应的值

Question

cookie(名称为cookie1) userName=1&userGuid=3ED70789CC5EA5E755340A73C71DD7B4
cookie(名称为cookie2) userName=2&userGuid=3ED70789CC5EA5E755340A73C71DD7B4
这些cookie都是aspx.cs里面的
js怎么得到cookie2中 userName  Guid 的值

Answer 1

document.cookie;   <script> 
function CookieHelper() 
  {this.key="";//初始化key。 
   this.value="";//初始化key's value。 
   this.expires=0;//初始化cookie的有效时间，单位毫秒。

                  return false; 
                 } 
               var cookie=document.cookie; 
               var start=cookie.indexOf(key+"="); 
               if(start==-1) 
                 {alert("欲查找的cookie不存在！") 
                  return false; 
                 } 
               var end=cookie.indexOf(";",start); 
                             if(end==-1) 
                               end=cookie.length; 
               var getCookie=cookie.substring(start+key.length+1,end);

                    {var dt=new Date(); 
                   dt.setTime(dt.getTime()); 
                                     while(document.cookie!="") 
                                       document.cookie=document.cookie+";expires="+dt.toGMTString(); 
                                     this.init(); 
                                     return true 
                                    } 
  } 
var cookieTest=new CookieHelper() 
function settest() 
{cookieTest.key="test" 
 cookieTest.value="ok" 
 cookieTest.expires=31536000000

<input type=button onclick="cookieTest.destroy()" value=clear>
<input type=button onclick=cookieTest.get("test") value=gettest>
<input type=button onclick=cookieTest.get("a") value=geta>
<input type=button onclick=cookieTest.set("test",1,31536000000) value=resetTest>
<input type=button onclick=cookieTest.del("test") value=delTest> 

Answer 2

function getCookie(objName){//获取指定名称的cookie的值
  var arrStr = document.cookie.split("; ");
  for(var i = 0;i < arrStr.length;i ++){
  var temp = arrStr[i].split("=");
  if(temp[0] == objName) return unescape(temp[1]);
  } 
}var s=getCookie("cookie2");
s=s.split('userGuid')[1].replace('=','');
alert(s)

Answer 3

不知道我是否理解错误。总之getCookie(objName)是可以取得名为objName变量的COOKIE。你自己参照一下试试
