如何存储在localStorage的数组？ [英] how to store an Array in localStorage?

问题描述

如果我不需要本地存储，我的code是这样的：

If i didn't need localStorage, my code would look like this:

var names=new Array(); 
names[0]=prompt("New member name?");

这个工作，但是我需要这个变量保存在localStorage的和它的证明很固执。我试过：

This works, however I need to store this variable in localStorage and its proving quite stubborn. I've tried:

var localStorage[names]=new Array();
localStorage.names[0]=prompt("New member name?");

我在哪里去了？

推荐答案

的localStorage 仅支持字符串。使用 JSON.stringify（）和 JSON.parse（）来。

localStorage only supports strings. Use JSON.stringify() and JSON.parse().

var names = [];
names[0] = prompt("New member name?");
localStorage.setItem("names", JSON.stringify(names));

//...
var storedNames = JSON.parse(localStorage.getItem("names"));
