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:)

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。

init: function () {
this.browser = this.searchString(this.dataBrowser) || "An unknown browser";
this.version = this.searchVersion(navigator.userAgent)

this.OS = this.searchString(this.dataOS) || "an unknown OS";

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。
$.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。
