通过window.navigator来判断：

 function getBrowserInfo(){

     var Info = {};

     var str = window.navigator.userAgent.toLowerCase();

     var bReg =/(msie|firefox|chrome|opera|version).*?([\d.]+)/;

     var infoArr = str.match(bReg);

     Info.browser = infoArr[1].replace(/version/, "safari");

     Info.ver = infoArr[2];

     return Info;

 }

 var BomInfo = getBrowserInfo();

 document.write(BomInfo.browser);
13 document.write("</br>");

 document.write(BomInfo.ver);
