我如何显示所有localStorage保存的变量？

我想要访问保存在特定页面上的所有localStorage变量。 我怎么做？ 我想展示它，就像我将使用join（）函数显示数组一样

您可以尝试迭代localStorage对象中的所有项目：

for (var i = 0; i < localStorage.length; i++){
    // do something with localStorage.getItem(localStorage.key(i));
}

我经常使用这段代码：

var i;

console.log("local storage");
for (i = 0; i < localStorage.length; i++)   {
    console.log(localStorage.key(i) + "=[" + localStorage.getItem(localStorage.key(i)) + "]");
}

console.log("session storage");
for (i = 0; i < sessionStorage.length; i++) {
    console.log(sessionStorage.key(i) + "=[" + sessionStorage.getItem(sessionStorage.key(i)) + "]");
}

您还可以在Google Chrome开发人员工具中检查localStorage状态和数据
