“IE8 除外"的条件注释?

2022-01-20 00:00:00 comments conditional javascript html internet-explorer-8

我正在使用 <!--[if IE 8]><![endif]--> 来定位 IE8，但是我想加载一些 JS除了 IE8 之外的所有浏览器，我应该使用什么条件注释?

I'm using <!--[if IE 8]><![endif]--> for targeting IE8, but there's some JS that I want to load for all browsers EXCEPT IE8, what conditional comment should I use?

我想知道这是否可行:<!--[if lte IE 8]><![endif]-->

谢谢

推荐答案

我能想到一个窍门.在 IE 条件标记内设置一个变量，如果没有设置该变量，则包含您的 JS 代码.

I can think of a trick. Set a variable inside the IE conditional tag and include your JS code if that variable isn't set.

<script>
    var ie8 = false;
</script>

<!--[if IE 8]>
    <script>
        ie8 = true;
    </script>
<![endif]-->

<script>
    if (ie8 == false) {
        // any code here will not be executed by IE 8
        alert("Not IE 8!");
    }
</script>
