我的 localStorage 结果显示 [null,null,"something"]] 而不是 "something"

Question

我的问题是结果显示是[null,null,"something"]]而不是"something"。

我的代码如下所示：

var simpan = JSON.parse(localStorage.getItem('subject')) || [];
                        simpandata.push(subjek);
                        localStorage.setItem('subject', JSON.stringify(simpandata));

var showsubjek = localStorage["subject"];
        showsubjek = JSON.stringify(showsubjek);
        showsubjek2 = JSON.parse(showsubjek);
        document.getElementById("getItemitu").innerHTML=showsubjek2;

如果我删除此代码：showsubjek = JSON.stringify(showsubjek); 结果将显示[object, object]...

获取localStorage值如下图（正确方法）。

错误的方式

var showsubjek = localStorage["subject"];

正确方法

var showsubjek = localStorage.getItem("subject");
