HomeWeb Front-endHTML Tutorial在html中判断IE浏览器的版本_html/css_WEB-ITnose

如何让静态HTML代码根据不同IE版本显示不同内容。 这里的技巧就是利用IE的HTML注释表达式。

HTML 的注释格式是 , IE 对HTML注释做了一些扩展,使之可以支持条件判断表达式:

   当表达式expression 为True 的时候,显示 HTML 内容。

例子:

view plaincopy to clipboardprint?
  

和编程语言类似,这里的表达式还支持大于(gt)、小于(lt)、 与或非 等操作符。 下面是一些例子。

[if IE]   判断是否IE

[if IE 7]  判断是否是IE7

[if !IE]  判断是否不是IE

[if lt IE 5.5]  判断是否是IE5.5 以下版本。  (

[if lte IE 6]   判断是否等于IE6 版本或者以下 (

[if gt IE 5]  判断是否IE5以上版本  (> )

[if gte IE 7]  判断是否 IE7 版本或者以上

[if !(IE 7)] 判断是否不是IE7

[if (gt IE 5)&(lt IE 7)]   判断是否大于IE5, 小于IE7

[if (IE 6)|(IE 7)]  判断是否IE6 或者 IE7

代码示例:

view plaincopy to clipboardprint?
  

You are not using Internet Explorer.

 注:IE5 以下的版本不支持这种注释扩展。 不过现在也很难找到IE4了 ... :)
