Safari 不保存 cookie 数据，但 IE/FF 会保存？

我在 Safari 中遇到了这个奇怪的问题。我使用 JavaScript 将用户选择数据存储在 cookie 中。

我使用以下代码创建 cookie -

document.cookie = cookieName +
           "=" + encodeURIComponent(cookieValue) +
           "; expires=" + jsDate.toGMTString();

并使用它读取 -

var cookie = document.cookie;
    if(cookie.length !== 0){
         var theCookie=" "+document.cookie;
         var ind=theCookie.indexOf(" "+cookieName+"=");
         if (ind==-1) ind=theCookie.indexOf(";"+cookieName+"=");
         if (ind==-1 || cookieName=="") return "";
         var ind1=theCookie.indexOf(";",ind+1);
         if (ind1==-1) ind1=theCookie.length; 
         return unescape(theCookie.substring(ind+cookieName.length+2,ind1));}
        else { return '';}

该代码在 Firefox 和 IE 中工作正常，但当我在 Safari 中访问此 cookie 的数据时 - 返回一个空字符串。奇怪的是，如果我重复我的选择并重试，我可以访问数据。换句话说，当我第一次访问我的网站时，cookie 数据不可用，但在后续尝试中，数据可用！

要再次看到这个问题，我必须清除 Safari 的缓存、历史记录并从“显示 cookie”部分删除 cookie，然后重新打开浏览器。

另一个观察结果 - 当我无法读取 cookie 数据时，当我们在 Safari > 下查看时，我们可以看到 cookie。首选项>安全>显示cookies

I'm stuck with this weird issue in Safari. I'm storing a user selection data in a cookie using javascript.

I create the cookie using following code -

document.cookie = cookieName +
           "=" + encodeURIComponent(cookieValue) +
           "; expires=" + jsDate.toGMTString();

and its read using -

var cookie = document.cookie;
    if(cookie.length !== 0){
         var theCookie=" "+document.cookie;
         var ind=theCookie.indexOf(" "+cookieName+"=");
         if (ind==-1) ind=theCookie.indexOf(";"+cookieName+"=");
         if (ind==-1 || cookieName=="") return "";
         var ind1=theCookie.indexOf(";",ind+1);
         if (ind1==-1) ind1=theCookie.length; 
         return unescape(theCookie.substring(ind+cookieName.length+2,ind1));}
        else { return '';}

This code works fine in Firefox and IE but when I access this cookie's data in Safari - an empty string is returned. The weird thing is, if i REPEAT my selection and try again, i can access the data. In other words, the first time i access my site, the cookie data is unavailable but in subsequent attempts the data is available!

To see this issue again, i have to clear Safari's cache, history and delete the cookies from the "Show cookies" section and reopen the browser.

Another observation - when i fail to read the cookie data, we can see the cookie when we look under Safari > Preferences > Security > Show cookies

ps:
facing this with Safari version 4 & 5
