推荐答案

你需要记住用户是否已经访问过该网站，只有在没有的情况下才显示该消息。



如果您的服务器端代码需要知道用户是否是第一次访问，那么我需要使用 cookie [ ^ ]。



如果你只需要从Javascript知道，那么使用本地存储：

Window.localStorage - Web APIs | MDN [ ^ ]

然而，如果你是尝试打开新的浏览器窗口（ window.open [ ^ ]）那样不行。您的弹出窗口将被内置于每个主要浏览器的弹出窗口阻止程序阻止。相反，您需要在页面中显示您的消息，使用 jQuery UI的对话框 [ ^ ]或 Bootstrap的模态 [ ^ ]。

You'll need to remember whether the user has already visited the site, and only show the message if they haven't.

If your server-side code needs to know whether it's the user's first visit, you'll need to use a cookie[^].

If you only need to know from Javascript, then use local storage:
Window.localStorage - Web APIs | MDN[^]

However, if you're trying to open a new browser window (window.open[^]) automatically when the page loads, that will not work. Your popup will be blocked by the popup blocker built in to every major browser. Instead, you'll need to show your message within the page, using something like jQuery UI's Dialog[^] or Bootstrap's Modal[^].
