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;
}
其他回答
var isOpera = !!window.opera || navigator.userAgent.indexOf('Opera') >= 0;
// Opera 8.0+ (UA detection to detect Blink/v8-powered Opera)
var isFirefox = typeof InstallTrigger !== 'undefined'; // Firefox 1.0+
var isSafari = Object.prototype.toString.call(window.HTMLElement).indexOf('Constructor') > 0;
// At least Safari 3+: "[object HTMLElementConstructor]"
var isChrome = !!window.chrome; // Chrome 1+
var isIE = /*@cc_on!@*/false;

您可以使用jQuery库来检测浏览器版本。
例子:
jQuery.browser.version
然而，这只有在你同时使用jQuery的其他函数时才有意义。对我来说，仅仅为了检测浏览器而添加整个库似乎有点小题大做。

我知道我问这个问题已经晚了，但我想我会在这里抛出我的片段。这里的很多答案都是OK的，而且，正如有人指出的那样，通常最好使用特性检测而不是依赖userAgent字符串。但是，如果您打算走这条路，我已经写了一个完整的代码片段，以及一个替代的jQuery实现来取代被放弃的$.browser。

我的第一个代码片段只是向导航器对象添加了四个属性:浏览器、版本、移动设备和webkit。
