js 取后台定义的cookies

Question

我在后台定义了几个cookies 
Response.Cookies.Add(new HttpCookie("Msg001", "1234"));
Response.Cookies.Add(new HttpCookie("Msg002", "5678"));
我想在前台用JS取这些cookies的值
怎么用判断Msg001的cookies是否为空？
怎么取到Msg001的value值？

Answer 1

你看下js 获取cookie，或者用jq的cookie插件

Answer 2

var strCookie=document.cookie;
//将多cookie切割为多个名/值对
var arrCookie=strCookie.split("; ");
var value;
for(var i=0;i<arrCookie.length;i++)
{
    if(arrCookie[i].indexOf('Msg001')>0)
    {
        value=arrCookie[i].split('=')[1];
    }
}

Answer 3

以下内容来自Dreamweaver
// Example:// alert( readCookie("myCookie") );function readCookie(name){  var cookieValue = "";  var search = name + "=";  if(document.cookie.length > 0)  {     offset = document.cookie.indexOf(search);    if (offset != -1)    {       offset += search.length;      end = document.cookie.indexOf(";", offset);      if (end == -1) end = document.cookie.length;      cookieValue = unescape(document.cookie.substring(offset, end))    }  }  return cookieValue;}
