我正在 build 这个网站，由于我没有为通过手机和其他小型设备访问它的人设置任何移动布局，我想将他们重定向到一个单独的 mobile_redirect.html 文件，其中包含指向主站点的链接和免责声明。他们仍然可以从那里点击链接并在手机上转到主站点。
除了无法让我在手机上访问主站点之外，我拥有的一切都可以正常工作。我相信这是因为我的全局变量 **hasBeenRedirected** 没有设置为 true，原因我无法弄清楚。
我使用的方法涉及多个 .js 文件编辑单个全局变量 **hasBeenRedirected**，它在 index_main.js 中声明
我试图让所有用户必须做的就是访问单独的 mobile_redirect.html 文件(它们自动链接到该文件)以设置全局变量 hasBeenRedirected 到 true——使他们可以在不被重定向的情况下访问主站点，但我显然遗漏了一些东西 :P
来自 index_main.js 的片段:
window.hasBeenRedirected = false; // has the user been redirected to our mobile site or not
//"things" to do as soon as our webpage loads
$(document).ready(function(){
"use strict";
//if they have a tiny screen then redirect them to the mobile_redirect.html file
if(screen.width <= 800 && !window.hasBeenRedirected){
window.location = "http://www.summitsets.com/mobile_redirect.html";
}
//....code continues but not relevant here
mobile_redirect.js
//if the user has been redirected once then we wanna make sure we don't do it again!
$(document).ready(function(){
"use strict";
window.hasBeenRedirected = true;
});

这似乎是一篇大文章，但我觉得解决方案似乎很简单。我只是想为我的问题提供尽可能多的资源。
如果您愿意，您可以在手机上访问我的网站，实际进行现场测试。您会注意到您无法访问主站点，因为它一直在重定向您。
提前致谢!
最佳答案
我建议使用 cookie，因为在重定向时 javascript 会丢失所有保存在内存中的数据。
所以在你的移动 _redirect.js 而不是全局对象中最好设置一个 cookie:
document.cookie = "isMobile=true";
然后即使页面被重定向，你也可以访问 cookie
var foo = document.cookie;
关于javascript - 仅将移动用户重定向到不同的 .html 文件一次，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40365238/
