如何将数组存储在localStorage中？ [英] How do I store an array in localStorage?

问题描述

如果我不需要localStorage，我的代码将如下所示：

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

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

这有效。但是，我需要将此变量存储在localStorage中，并且证明它非常固执。我已经尝试过：

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

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

我要去哪里？

Where am I going wrong?

推荐答案

localStorage 只支持字符串。使用 JSON.stringify（）和 JSON.parse（）。

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"));
