以上代码通过测试,可用!
但存在一个问题,即IE5与IE7浏览器暂不能区分,以下是IE5与IE7下userAgent的信息;通过userAgent发现,简单的通过以上方法,无法正确区分IE5和IE7。期待该问题的解决方案!!!
IE5: userAgent "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; InfoPath.2; .NET4.0E)"
IE7: userAgent "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; InfoPath.2; .NET4.0E)"
var isEdge = (userAgent.indexOf("Windows NT 6.1; Trident/7.0;") > -1 || userAgent.indexOf("Windows NT 6.1; WOW64; Trident/7.0;")) && !isIE; //判断是否IE的Edge浏览器
