如何屏蔽IE8及以下？
[英]How to block IE8 and down?
问题描述
We just finished developing a web application and we want to block Internet Explorer 8 and down.
我们刚刚完成了一个 Web 应用程序的开发，我们想要阻止 Internet Explorer 8 及以下版本。 What is the best way to accomplish this?实现这一目标的最佳方法是什么？
I found a way to block IE6, however the tutorial ( http://css-tricks.com/ie-6-blocker-script/ ) is from 2008 and I feel like it's a bit dated.我找到了一种阻止 IE6 的方法，但是教程 ( http://css-tricks.com/ie-6-blocker-script/ ) 是 2008 年的，我觉得它有点过时了。 We also want to block IE 7 and 8...我们还想阻止 IE 7 和 8...
The site is built in CodeIgniter with a lot of Backbone.js.该站点是在 CodeIgniter 中构建的，其中包含大量 Backbone.js。
If anyone has any ideas they would be appreciated.如果有人有任何想法，他们将不胜感激。
Thanks!谢谢！

Sorry guys, more information: Yes I want to BLOCK them, I want to display a message and be able to style the page to say "Sorry, you use Internet Explorer which isn't a web browser, please download CHROME here".抱歉，各位，更多信息：是的，我想阻止他们，我想显示一条消息并能够将页面样式设置为“抱歉，您使用的 Internet Explorer 不是网络浏览器，请在此处下载 CHROME”。

Do it with CSS and conditional comments.使用 CSS 和条件注释来完成。
<head>
<!--[if IE lte 8]>
<link rel="stylehseet" type="text/css" href="blockIE.css" />
<[endif]-->
</head>
<body>
<div class="yourcontent">
...
</div>
<div class="notification">
<h1>Sorry, we don't support your old browsers</h1>
</div>
</body>
CSS: CSS：
body * { display: none }
.notification { display: block; }

You can also do it with CodeIgniter, https://www.codeigniter.com/user_guide/libraries/user_agent.html您也可以使用 CodeIgniter， https: //www.codeigniter.com/user_guide/libraries/user_agent.html
Something like:就像是：
$this->load->library('user_agent');
if ($this->agent->browser() == 'Internet Explorer' && $this->agent->version() <= 8){
//Redirect or show error
}

You can do it using jQuery:你可以使用 jQuery 来做到这一点：
//if its internet explorer...
if(jQuery.browser.msie){
//getting the version
if($.browser.version < 8){
//do whatever
}
}

I believe the fastest and safest method of avoiding conflict with other parts of your page code is...我相信避免与页面代码的其他部分发生冲突的最快和最安全的方法是......
<html>
<head>
<!--[if IE lte 8]><script>location.href="my_message.html";</script><[endif]-->
<!--your other head code-->
</head>
<body>
<!--your body code-->
</body>
</html>
