JS代码判断浏览器类型以及版本

browserVersion:function(){

var explorer = window.navigator.userAgent;

if (explorer.indexOf("MSIE") >= 0) {// ie10及以下

var b_version = navigator.appVersion;

var version = b_version.split(";");

version = version[1].replace(/[ ]/g, "");

version = version.split('MSIE')[1];

browser = 'IE:' + version;

} else if (explorer.indexOf("Firefox") >= 0) {// Firefox

browser = 'Firefox';

} else if (explorer.indexOf("Chrome") >= 0) {// Chrome

browser = 'Chrome';

} else if (explorer.indexOf("Opera") >= 0) {// Opera

browser = 'Opera';

} else if (explorer.indexOf("Safari") >= 0) {// Safari

browser = 'Safari';

} else if (explorer.indexOf("Trident/7.0") >= 0) {// IE11

browser = 'IE:10.0以上';

}

return borwser;
