用于Internet Explorer浏览器版本用户代理的Javascript重定向？ [英] Javascript redirect for Internet Explorer browser version user agent?

问题描述

我发现我的javascript密集型网站在IE9中无法可靠（或根本没有）。

I found out that my javascript-intensive web site doesn't work reliably (or at all) in IE9.

它在标题中使用兼容模式元标记（通常但不总是），但我只是想构建一个我知道可以很好地工作的页面IE9然后在检测到IE9时将常用页面重定向到它。在IE 7和8（以及我尝试过的所有其他浏览器）中，通常的页面都很好。

It works, (usually, but not always) with the compatibility mode meta tag in the header, but I just want to build a page that I know will work well in IE9 and then have the usual page redirect to it when IE9 is detected. The usual page is fine in IE 7 and 8 (and every other browser I've tried it on).

任何人都可以给我一些javascript来做到这一点吗？谢谢！

Can anyone give me some javascript that will do that? Thank you!

这是我的常用页面：

推荐答案

最简单的方法是使用 IE条件。

The simplest way would be to use IE Conditionals.

注意： IE10及更高版本删除了此功能的支持。对于现代浏览器，为了兼容性目的，有条件地显示内容的广泛接受的方法是使用特征检测。 Modernizr 是一个用于处理特征检测的流行库。

Note: IE10 and beyond have removed support for this feature. For modern browsers the widely accepted way of conditionally displaying content for compatibility purposes is using feature detection. Modernizr is a popular library built for handling feature detection.

例如：

<!--[if IE 9]>
<script type="text/javascript">
    window.location = "http://www.ie9version.com";
</script>
<![endif]-->

条件网站的例子：

<!--[if IE]><p>You are using Internet Explorer.</p><![endif]-->
<![if !IE]><p>You are not using Internet Explorer.</p><![endif]>

<!--[if IE 7]><p>Welcome to Internet Explorer 7!</p><![endif]-->
<!--[if !(IE 7)]><p>You are not using version 7.</p><![endif]-->

<!--[if gte IE 7]><p>You are using IE 7 or greater.</p><![endif]-->
<!--[if (IE 5)]><p>You are using IE 5 (any version).</p><![endif]-->
<!--[if (gte IE 5.5)&(lt IE 7)]><p>You are using IE 5.5 or IE 6.</p><![endif]-->
<!--[if lt IE 5.5]><p>Please upgrade your version of Internet Explorer.</p><![endif]-->

<!--[if true]>You are using an <em>uplevel</em> browser.<![endif]-->
<![if false]>You are using a <em>downlevel</em> browser.<![endif]>

<!--[if true]><![if IE 7]><p>This nested comment is displayed in IE 7.</p><![endif]><![endif]-->
