我想存储JavaScript数组作为Cookie [英] I want to store Javascript array as a Cookie

问题描述

有可能，我有一个列表，我想把它存储在浏览器，如果不可能，什么是有效的方式这样做？

Is it possible, I have a some sort of list and I want to store it on browser, if it is not possible, what is the efficient way of doing this?

推荐答案

JSON编码，有效地产生一个字符串{name：'myname' 'myage'}，它放在一个cookie中，需要时检索并解码回一个JavaScript数组/对象。

JSON encode it, effectively producing a string like "{name:'myname',age:'myage'}" which you put in a cookie, retrieve when needed and decode back into a JavaScript array/object.

数组中的数组：

var arr = ['foo', 'bar', 'baz'];
var json_str = JSON.stringify(arr);
createCookie('mycookie', json_str);

稍后，以数组形式检索cookie的内容：

Later on, to retrieve the cookie's contents as an array:

var json_str = getCookie('mycookie');
var arr = JSON.parse(json_str);

注意：cookie函数不是原生的，取自如何创建和读取cookie中的值？

Note: cookie functions are not native, taken from How do I create and read a value from cookie?
