JS判断浏览器种类

function myBrowser() {
                        var userAgent = navigator.userAgent; //取得浏览器的userAgent字符串
                        var isOpera = userAgent.indexOf("Opera") > -1; //判断是否Opera浏览器
                        var isIE = userAgent.indexOf("compatible") > -1 && userAgent.indexOf("MSIE") > -1 && !isOpera; //判断是否IE浏览器
                        var isFF = userAgent.indexOf("Firefox") > -1; //判断是否Firefox浏览器
                        var isSafari = userAgent.indexOf("Safari") > -1; //判断是否Safari浏览器
                        var isChrome = userAgent.indexOf("Chrome") > -1; //判断是否Chrome浏览器
                        if (isIE) {
                            var IE5 = IE55 = IE6 = IE7 = IE8 = false;
                            var reIE = new RegExp("MSIE (\\d+\\.\\d+);");
                            reIE.test(userAgent);
                            var fIEVersion = parseFloat(RegExp["$1"]);
                            IE55 = fIEVersion == 5.5;
                            IE6 = fIEVersion == 6.0;
                            IE7 = fIEVersion == 7.0;
                            IE8 = fIEVersion == 8.0;
                            if (IE55) {
                                return "IE55";
                            }
                            if (IE6) {
                                return "IE6";
                            }
                            if (IE7) {
                                return "IE7";
                            }
                            if (IE8) {
                                return "IE8";
                            }
                        }//isIE end
                        if (isFF) {
                            return "FF";
                        }
                        if (isOpera) {
                            return "Opera";
                        }
                        if (isChrome) {
                            return "Chrome";
                        }
                    }//myBrowser() end
