推荐答案

您可以尝试使用 jQuery Cookie插件。

Cookie是一种持久存储的形式。当用户加载网页时，您可以检查他是否有某个Cookie。如果他没有，你向他显示启动页面并设置cookie。如果他有cookie设置意味着他以前在这里，你不需要做任何事情。下面的代码可以是一个解决方案，但我是从我的头写，所以你可能需要修改一下。假设您使用的是上述插件。

The cookie is a form of persistent storage. When a user loads the page, you check if he has a certain cookie. If he doesn't, you show him the splash page and set the cookie. If he has the cookie set that means he's been here before and you don't need to do anything. The following code could be a solution, but I'm writing it out of my head so you'd probably have to modify it a bit. It assumes you're using the plugin above.

if (visits = $.cookie('noOfVisits')) {
    $.cookie('noOfVisits', visits++);
} else {
    $.cookie('noOfVisits', 1);
    $('#splash').show();
}

我认为这是很自我解释。注意，cookie过期，研究如何使它最后只要你想要的。

I think that it's pretty self explanatory. Note that the cookie expires, research how to make it last as long as you want.
