[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 ... :)
