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.
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 ... :)
