检查IE8是否使用纯Javascript [英] Check if IE8 with pure Javascript

问题描述

我以前用这种方式检查：

I used to check it this way:

$.browser.msie && $.browser.version == 8

但似乎 $。浏览器已从jQuery的后续版本中删除，

But it seems that $.browser has been removed from the later versinos of jQuery,

所以，

如何我可以用纯粹的javascript检查吗？

How can I check that with just pure javascript?

我试过：

isIE8： navigator.appVersion.indexOf（MSIE 8）> 0

好像这样做，但它看起来不那么好，实际上看起来有很多瑕疵......

Wich seems to Do it, but it doesn't look that good and actually looks like it have many flaws...

任何更好的形式给出？

推荐答案

这比单行更长你可能想要，但比解析UA字符串更安全，因为它是基于实际行为（IE条件评论）： https ：//gist.github.com/paulirish/357741

This is longer than the one-liner you probably want, but safer than parsing the UA string, because it's based on actual behaviour (IE conditional comments): https://gist.github.com/paulirish/357741
