使用Javascript设置Cookie并清理值 [英] Set Cookie with Javascript and sanitize value

问题描述

我需要使用以下命令通过javascript设置cookie：

I need to set a cookie with javascript which I'm doing this with the following command:

document.cookie = name+"="+value;

我的问题是 value 是一个字符串，可以包含任何Unicode字符。

My problem is that value is a string, which can contain any unicode-character.

是否有一个自动替换特殊字符的功能（例如; ） -并且如果不是，则禁止使用哪些字符？

Is there a function which automatically replaces special characters (like ;) - and if not, which characters are forbidden?

类似于 encodeURIComponent（）的Get-Parameters函数将是完美的

Something like the "encodeURIComponent()"-Function for Get-Parameters would be perfect

推荐答案

您应使用 window.escape 。

scape（）方法转换特殊字符（不是常规文本或数字的任何字符）转换为十六进制字符，这对于设置cookie的值尤其必要。在GET请求或AJAX GET / POST请求的URL中传递name = value对时，也很有用。

The escape() method converts special characters (any characters that are not regular text or numbers) into hexadecimal characters, which is especially necessary for setting the values of cookies. Also useful when passing name=value pairs in the URL of a GET request, or an AJAX GET/POST request.

window.unescape

更新。
使用 base64 进行编码/解码，以免Unicode字符支出少于$$ c c> window.encode 。

Upd. It may make some sense to use base64 encoding/decoding prior to escaping in order not to suffer that much from unicode characters expenditure by window.encode.
