javascript - iPad Safari iOS - SECURITY_ERR：访问“document.cookie”时出现 Dom 异常 18

Question

Running Safari on iOS 5.1 (iPad), my JavaScript code is throwing the following exception:

SECURITY_ERR: Dom Exception 18: An attempt was made to break through the security policy of the user agent

...whenever I make a call to document.cookie

Now this is a remotely hosted website accessed via a proper URL. All desktop browsers run fine, this only affects Safari on my iPad. I tried to Google the error, but I'm just getting references to calling local files (file://) which I'm not doing as it's a remote website.

Any ideas?

Answer 1

1. 启用 cookie？可能是 cookie 被阻止了。
2. 协议不匹配？例如 https 页面中的 Http 脚本。
3. 到大饼干大小？
4. cookie 值中的非法字符？
5. 你在使用 iOS UIWebView 吗？它可以是非 uri 方案协议（又名 file://）
6. 您是否尝试从 iframe 获取 cookie？

检查所有这些，有时它像魔术一样奇怪。
