我想将 Javascript 数组存储为 Cookie [英] I want to store Javascript array as a Cookie

问题描述

有可能吗，我有一个列表，我想将它存储在浏览器上，如果不可能，这样做的有效方法是什么?

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 对其进行编码，有效地生成一个类似于 "{name:'myname',age:'myage'}" 的字符串放入 cookie，在需要时检索并解码回 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.

示例 - 在 cookie 中存储数组:

Example - store array in a cookie:

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 如何从 cookie 创建和读取值?

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