如果浏览器是ie9,则执行某些javascript [英] Execute certain javascript if browser lt ie9
问题描述
如果浏览器低于IE9,我想在jQuery中执行某些代码。是的,我已经知道了
I want to execute a certain code in jQuery if the browser is lower than IE9. And yes, i already know about
<!--[if ... IE ]> <![endif]-->
但我想要的是在scipt标签和jQuery document.ready中检查这个条件
But what i want is to check this condition within the scipt tag and with jQuery document.ready
<script>
$(document).ready(function(){
//code to check if lt ie9
});
</script>
推荐答案
您可以定位较旧的Internet Explorer版本(< = 9)通过< html>
元素上的类......
You can target older Internet Explorer versions (<= 9) through classes on the <html>
element...
<!--[if lt IE 7]> <html class="ie ie6 lte9 lte8 lte7"> <![endif]-->
<!--[if IE 7]> <html class="ie ie7 lte9 lte8 lte7"> <![endif]-->
<!--[if IE 8]> <html class="ie ie8 lte9 lte8"> <![endif]-->
<!--[if IE 9]> <html class="ie ie9 lte9"> <![endif]-->
<!--[if gt IE 9]> <html> <![endif]-->
<!--[if !IE]><!--> <html> <!--<![endif]-->
...然后检查< html>
具有类 .lt9
或 .lt8
- 您要定位的Internet Explorer的任何版本:
... and then check if <html>
has the class .lt9
or .lt8
— whatever version of Internet Explorer you are targeting:
if($('html').hasClass('lte9')) { /* LTE IE9 */ }
但是,我建议使用 Modernizr 功能检测而不是检查特定浏览器。
However, I would suggest using Modernizr feature detection instead of checking for a specific browser.
