我正在处理一个需要JavaScript和会话的页面.我已经有代码来警告用户是否禁用了javascript.现在,我想处理禁用cookie的情况,因为会话ID存储在cookie中.
I am working on a page that requires javascript and sessions. I already have code to warn the user if javascript is disabled. Now, I want to handle the case where cookies are disabled, as the session id is stored in cookies.
我想到的只是几个主意:

基于链接的文章,我想出了自己的方法,并认为我会分享,其他人也许可以使用它,也许我会得到一些批评. (假设您的PHP会话存储在名为PHPSESSID的cookie中)
Based on the articles linked, I came up with my own approach and thought I would share, somebody else might be able to use it, maybe I will get a few critiques. (Assumes your PHP session stores in a cookie named PHPSESSID)
<div id="form" style="display:none">Content goes here</div> <noscript>Sorry, but Javascript is required</noscript> <script type="text/javascript"><!-- if(document.cookie.indexOf('PHPSESSID')!=-1) document.getElementById('form').style.display=''; else document.write('<p>Sorry, but cookies must be enabled</p>'); --></script>推荐答案
JavaScript
在JavaScript中,您可以对 cookieEnabled 属性进行简单测试.主要浏览器.如果您使用的是较旧的浏览器,则可以设置Cookie并检查其是否存在. (从 Modernizer 借用):
JavaScript
In JavaScript you simple test for the cookieEnabled property, which is supported in all major browsers. If you deal with an older browser, you can set a cookie and check if it exists. (borrowed from Modernizer):
if (navigator.cookieEnabled) return true; // set and read cookie document.cookie = "cookietest=1"; var ret = document.cookie.indexOf("cookietest=") != -1; // delete cookie document.cookie = "cookietest=1; expires=Thu, 01-Jan-1970 00:00:01 GMT"; return ret;
- Modernizer cookie检查提交
- 检查是否已启用Cookie
- Modernizer cookie check commit
- Checking if Cookies are Enabled
- 检测是否Cookie已通过PHP启用

在PHP中,它相当复杂",因为您必须刷新页面或重定向到另一个脚本.在这里,我将使用两个脚本:
In PHP it is rather "complicated" since you have to refresh the page or redirect to another script. Here I will use two scripts:
somescript.php
<?php session_start(); setcookie('foo', 'bar', time()+3600); header("location: check.php");check.php
<?php echo (isset($_COOKIE['foo']) && $_COOKIE['foo']=='bar') ? 'enabled' : 'disabled';
