核心代码：
代码如下:


var cookie={ 
setCookie:function (name, value, iDay) { 
var oDate = new Date(); 
oDate.setDate(oDate.getDate()+iDay); 
document.cookie = name+'='+value+';expires='+oDate; 
}, 
getCookie:function (name) { 
var arr = document.cookie.split('; '); 
for (var i = arr.length - 1; i >= 0; i--) { 
var arr2 = arr[i].split('='); 
if(arr2[0]===name){ 
return arr2[1]; 
} 
} 
return ''; 
}, 
removeCookie:function (name) { 
cookie.setCookie(name,1,-1); 
} 
}; 
 
测试： 
 
<html> 
<head> 
<title></title> 
</head> 
<script> 
var cookie={ 

setCookie:function (name, value, iDay) { 
var oDate = new Date(); 
oDate.setDate(oDate.getDate()+iDay); 
document.cookie = name+'='+value+';expires='+oDate; 
}, 
getCookie:function (name) { 
var arr = document.cookie.split('; '); 
for (var i = arr.length - 1; i >= 0; i--) { 
var arr2 = arr[i].split('='); 
if(arr2[0]===name){ 
return arr2[1]; 
} 
} 
return ''; 
}, 
removeCookie:function (name) { 
cookie.setCookie(name,1,-1); 
} 
}; 
cookie.setCookie('username','iceshu',33); 
// setCookie('pwd','ff',365); 
cookie.removeCookie('username'); 
alert(document.cookie) 
alert(cookie.getCookie('pwd')); 
</script> 
<body> 
</body> 
</html>
