JavaScript如何在localStorage中存储阵列？

Question

如果我不需要localStorage，我的代码将如下所示：

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

这可行。但是，我需要将此变量存储在localStorage中，事实证明它很顽固。我试过了：

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

我要去哪里错了？

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

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

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