如果在IE9中查看，是否要替换脚本? [英] Replace script if viewed in IE9?

问题描述

根据用户浏览器运行不同的javascript有多容易?

How easy would it be to run a different javascript depending on the user browser?

例如，如果某人使用IE9访问该网站，我希望它运行与正常为Chrome用户运行的脚本不同的脚本.

For example if someone visits the site with IE9 I would like it to run a different script to the one it would run normally for Chrome users.

推荐答案

您可以使用条件注释为此:

<!--[if lte IE 6]>
    <script>alert('lte stands for less than or equal to')</script>
<![endif]-->

<!--[if lt IE 7]>
    <script>alert('lt stands for less than')</script>
<![endif]-->

<!--[if gte IE 9]>
    <script>alert('gte stands for greater than or equal to')</script>
<![endif]-->
