Javascript sessionStorage 跨选项卡? [英] Javascript sessionStorage Across tabs?

问题描述

我使用 sessionStorage 来确保每个会话只发生一次操作.但是，如果用户打开一个新窗口 - sessionStorage 不会转移到新窗口，并且该操作将再次执行.请参阅下面的代码:

I am using sessionStorage to ensure an action only happens once per session. However, if a user opens a new window - the sessionStorage is not carried over to the new window, and the action is executed again. See my code below:

if sessionStorage.alreadyTracked != "1"
  sessionStorage.alreadyTracked = "1"
  ...

是否有一种适用于所有标签的简单方法?也许我需要使用 cookie?

Is there an easy way to do this that applies to all tabs? Maybe I need to use a cookie?

推荐答案

就 html5 存储而言，我会选择 localStorage.

As far as html5 storage goes i would go for localStorage in your case.

有关差异，请参见下文.

See below for the differences.

会话存储:

• 值仅在它们所在的窗口或选项卡中持续存在
  存储.
• 值仅在窗口或选项卡中可见创造了它们.

本地存储:

• 值保持窗口和浏览器的生命周期.
• 值在在同一来源运行的每个窗口或选项卡之间共享.
