How do I include a javascript if it's IE, and another javascript if everything else?

提问by TIMEX

I want to include <script src="ie.js">if the browser is IE.

<script src="ie.js">如果浏览器是 IE,我想包括在内。

Otherwise, include all.jsfor all other browsers.

否则,包括all.js所有其他浏览器。

How can I do this?

回答by aroth

You can do this using conditional comments. Example:

您可以使用条件注释来做到这一点。例子:

<!--[if IE]>
    <script src="ie.js">
<![endif]-->
<!--[if !IE]><!-->
    <script src="all.js"></script>
<!--<![endif]-->

回答by Matteo Calò

Conditional comments only work in IE, and are thus excellently suited to give special instructions meant only for IE. They are supported from IE 5 up until IE9 (inclusive).

条件注释仅适用于 IE,因此非常适合给出仅适用于 IE 的特殊指令。从 IE 5 到 IE9(含)都支持它们。
