javascript - ng存储: retrive data with variable key

Question

我需要一些帮助...

我需要使用 ngStorage Angular 插件从本地存储检索数据...

如果我写

$localStorage.temp = [{ name: "Jhon", lastname: "Pitt"}];
var myVar = $localStorage.temp;

这很好......但是如果我写

var str = 'temp';
$localStorage.temp = [{ name: "Jhon", lastname: "Pitt"}];
var myVar = $localStorage.[str]; // this doesn't work
myVar = $localStorage.str; // this doesen't retrieve nothing cause there's no key 'str' in local storage

如果我写这个

var myVar = JSON.parse(window.localStorage.getItem(str));

它有效，但我需要使用 $localStorage 我该如何解决这个问题？我非常需要它...

在我的 working plunker 中尝试一下

您确实很接近，但 $localStorage 上有语法错误。

尝试:

var str = 'temp';
$localStorage.temp = [{ name: "Jhon", lastname: "Pitt"}];
var myVar = $localStorage[str]; // remove the .
