javascript - 从 localStorage 获取 getElementByID

Question

我正在尝试从 localStorage 中存储的 key getElementById。我的本地存储中有以下数据:

question1 = Answer1

question2 = Answer2 etc.

和脚本:

<script>
if (localStorage.getItem("question1") === null) {
} else {
    document.getElementById('question1').innerHTML = (localStorage.getItem("question1"));
}

if (localStorage.getItem("question2") === null) {
} else {
    document.getElementById('question2').innerHTML = localStorage.getItem("question2");
}
</script>

但我想要的是，它将存储在 localStorage 中的每个键的值放在其 ElementById 中，并与键同名。

for (x in localStorage){
    document.getElementById(x).innerHTML = localStorage.getItem(x);
}

Answer 1

您可以使用spread运算符来执行以下操作

const items = { ...localStorage };

for (x in items){
    document.getElementById(x).innerHTML = localStorage.getItem(x);
}
