java代碼和js兩種方式判斷瀏覽器是不是IE11

 java代碼判斷瀏覽器是不是IE11

HttpServletRequest request = ServletActionContext.getRequest();
String agent = request.getHeader("User-Agent");

//判斷是IE瀏覽器並且不是IE11的時候
if (version.equals("WPS") && request.getHeader("User-Agent").toUpperCase().indexOf("MSIE") == -1 && !(null != agent && -1 != agent.indexOf("like Gecko"))) {
    System.out.print("是IE瀏覽器並且不是IE11");
}

js判斷瀏覽器是不是IE11

var u = window.navigator.userAgent.toLocaleLowerCase(),
ie11 = /(trident)\/([\d.]+)/,
style = u.match(ie11);
if(style){
     alert("該瀏覽器是ie11");       
}
