找出浏览器是IE6还是之前

标签: javascript jquery internet-explorer cross-browser

  

可能重复:
  Detect Internet Explorer 6 or below in jQuery

有没有办法使用javascript或jQuery检测浏览器是否在IE7之前(IE6或之前)?

我在这里找到了一个类似的问题,答案基本上是“不要那样做”。好吧,我不在乎,我还是想:)

答案 0 :(得分:6)

最有效的方式:

<!--[if lte IE 6]> insert code here <![endif]-->

如果您只想为IE 6及更低版本运行一些JavaScript,请在​​该条件注释中添加一个脚本块。

使用理由:

  • 仅被IE认可(其他人看到评论)
  • 你可以只使用IE浏览器,这可能是无效的语法,它仍然有效(这是一个评论)
  • 你可以使用这种语法
  • 将CSS,HTML和JavaScript中只使用IE浏览器

通过以下方式获取用过的浏览器:

navigator.userAgent

在jQuery中,您需要the $.browser method

如果浏览器是Internet Explorer,则

$.browser.msie返回true。

$.browser.version报告版本,如浏览器的标识字符串中所述。我不确定IE的各种版本报告了什么,所以我不确定你需要检查什么来识别7岁以上的IE。

根据文档,自jQuery 1.3起,$.browser已被弃用,但显然没有任何计划将其删除。
