复制代码 代码如下:

function getCookie(name)

{

var offset,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;

}

//name表示cookie的键的名字
