最近用jquery操作cookie时发现,存入的/被转义成了%2F
$.cookie('TICKET', '/mytestvalue', { expires: 1, path: '/' });
最后存入的值为:%2Fmytestvalue,
请问大神 ,这是什么问题,如果我要对/做相应处理,那么是否还有其他符号也会有这样的问题?目前只发现/
1. 就算我把/ 替换成//或者/// 或者//// 最后的结果只是 多几个%2F而已
2. 我把/ 替换成\/ 最后 结果也是%2F
3. .replace(/\//g, '\\/') 最后结果也是不行
少一个知识点:urlencode.就是url编码.在web里很多值都是要url编码的.
这里与url编码没关系的,我只是设置cookie的值,不过你的方案我还是试过了,不行,对/mytestvalue做url编码,就相当于:
$.cookie('TICKET', '%2Fmytestvalue', { expires: 1, path: '/' });//最后值cookie值就不对了
url解码:$.cookie('TICKET', '/Fmytestvalue', { expires: 1, path: '/' });//最后值自动变成了%2F
@CodeL: 你取出来的时候要urldecode
@吴瑞祥: 我就写死固定的值就不对 与取值没关系,js固定写死一个字符串
@吴瑞祥: 我用的jquery.cookie 版本:jQuery Cookie Plugin v1.4.0

看了一下源码,已找到问题,默认情况下jquery.cookie对我的值进行了url编码,导致了我的/变成了%2F
设置raw=true,不进行编码就好了
@吴瑞祥: 源码里面判断了config.raw
function encode(s) {
return config.raw ? s : encodeURIComponent(s);
}
function decode(s) {
return config.raw ? s : decodeURIComponent(s);
}
