如何使用JavaScript确定确切的浏览器和版本?
当前回答
下面的代码片段将显示如何显示UI元素取决于IE版本和浏览器
$(document).ready(function () {
var msiVersion = GetMSIieversion();
if ((msiVersion <= 8) && (msiVersion != false)) {
//Show UI elements specific to IE version 8 or low
} else {
//Show UI elements specific to IE version greater than 8 and for other browser other than IE,,ie..Chrome,Mozila..etc
}
}
);
下面的代码将给出我们如何获得IE版本
function GetMSIieversion() {
var ua = window.navigator.userAgent;
var msie = ua.indexOf('MSIE ');
if (msie > 0) {
// IE 10 or older => return version number
return parseInt(ua.substring(msie + 5, ua.indexOf('.', msie)), 10);
}
var trident = ua.indexOf('Trident/');
if (trident > 0) {
// IE 11 => return version number
var rv = ua.indexOf('rv:');
return parseInt(ua.substring(rv + 3, ua.indexOf('.', rv)), 10);
}
var edge = ua.indexOf('Edge/');
if (edge > 0) {
// Edge (IE 12+) => return version number
return parseInt(ua.substring(edge + 5, ua.indexOf('.', edge)), 10);
}
// other browser like Chrome,Mozila..etc
return false;
}

遗憾的是，IE11的导航器中不再有MSIE。
Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; OfficeLiveConnector.1.5; OfficeLivePatch.1.3; .NET4.0C; BRI/2; BOIE9;ENUS; rv:11.0) like Gecko
至于为什么你想知道你在使用哪个浏览器，这是因为每个浏览器都有自己的一组错误，你最终实现了浏览器和版本特定的解决方案，或者告诉用户使用不同的浏览器!

这是我正在使用的:
var ua = navigator.userAgent;
var info = {
browser: /Edge\/\d+/.test(ua) ? 'ed' : /MSIE 9/.test(ua) ? 'ie9' : /MSIE 10/.test(ua) ? 'ie10' : /MSIE 11/.test(ua) ? 'ie11' : /MSIE\s\d/.test(ua) ? 'ie?' : /rv\:11/.test(ua) ?

};

所有关于web浏览器的信息都包含在navigator对象中。名字和版本都在那里。
var appname = window.navigator.appName;
