Javascript - 将2d数组保存到本地存储并检索

Question

我有一个二维数组,保存信息,我需要保存到本地存储,然后检索.这是我的数据:

var content_array = [
    ["0","Mobile Application Development","CT5006","01/14/2013","Note"],
    ["1","Java Programming","CT5005","01/16/2013","Note"],
    ["2","Multimeida Application Development","CT5011","02/13/2013","Note"]
];

有什么简单的方法可以将其转换为字符串然后再转换为2D数组吗？

Answer 1

使用本机JSON.stringify方法:

var str = JSON.stringify(content_array);

然后,您可以使用该JSON.parse方法将其恢复为实际数组:

var content_array = JSON.parse(str);
