实际上有两种方法可以通过 JavaScript 清除 localStorage。
方法 1 − 使用 clear() 方法
localStorage.clear();
方法 2 − 遍历 localStorage 并删除所有键
for(key in localStorage){
delete localStorage[key];
}
Both ways will work.
示例
<html>
<body>
<p id = "storage"></p>
<script>
if (typeof(Storage) !== "undefined") {
localStorage.setItem("product", "Tutorix");
// cleared before displaying
localStorage.clear();
document.getElementById("storage").innerHTML = localStorage.getItem("product");
}
else {
document.getElementById("storage").innerHTML = "Sorry, no Web Storage
compatibility...";
}
</script>
</body>
</html>
