IE11을 감지하는 방법?

IE를 감지하려면이 코드를 사용하십시오.

function getInternetExplorerVersion()
{
  var rv = -1;
  if (navigator.appName == 'Microsoft Internet Explorer')
  {
    var ua = navigator.userAgent;
    var re  = new RegExp("MSIE ([0-9]{1,}[\.0-9]{0,})");
    if (re.exec(ua) != null)
      rv = parseFloat( RegExp.$1 );
  }
  return rv;
}
function checkVersion()
{
  var msg = "You're not using Internet Explorer.";
  var ver = getInternetExplorerVersion();

  if ( ver > -1 )
  {
    msg = "You are using IE " + ver;
  }
  alert( msg );
}

그러나 IE11은 "Internet Explorer를 사용하지 않습니다"를 반환합니다. 어떻게 감지 할 수 있습니까?

이 변경 목록에MSIE 따르면 IE11은 더 이상로보고하지 않습니다 . 오 탐지를 피하기위한 것입니다.

IE 를 정말로 알고 싶다면 할 수있는 일은 (테스트되지 않은)과 같은 반환 된 Trident/경우 사용자 에이전트에서 문자열 을 감지하는 것입니다.navigator.appNameNetscape

function getInternetExplorerVersion()
{
  var rv = -1;
  if (navigator.appName == 'Microsoft Internet Explorer')
  {
    var ua = navigator.userAgent;
    var re = new RegExp("MSIE ([0-9]{1,}[\\.0-9]{0,})");
    if (re.exec(ua) != null)
      rv = parseFloat( RegExp.$1 );
  }
  else if (navigator.appName == 'Netscape')
  {
    var ua = navigator.userAgent;
    var re  = new RegExp("Trident/.*rv:([0-9]{1,}[\\.0-9]{0,})");
    if (re.exec(ua) != null)
      rv = parseFloat( RegExp.$1 );
  }
  return rv;
}

console.log('IE version:', getInternetExplorerVersion());

IE11 (afaik)은 여전히 미리보기 상태이며 사용자 에이전트는 릴리스 전에 변경 될 수 있습니다.

!(window.ActiveXObject) && "ActiveXObject" in windowIE11을 명시 적으로 감지하는 데 사용 합니다.

IE (pre-Edge, "Trident") 버전을 감지하려면 "ActiveXObject" in window대신 사용하십시오.

MSInputMethodContext기능 감지 점검의 일부로 사용 하십시오. 예를 들면 다음과 같습니다.

//Appends true for IE11, false otherwise
window.location.hash = !!window.MSInputMethodContext && !!document.documentMode;

참고 문헌

나는 당신의 답변을 읽고 혼합했습니다. Windows XP (IE7 / IE8) 및 Windows 7 (IE9 / IE10 / IE11)에서 작동하는 것 같습니다.

function ie_ver(){  
    var iev=0;
    var ieold = (/MSIE (\d+\.\d+);/.test(navigator.userAgent));
    var trident = !!navigator.userAgent.match(/Trident\/7.0/);
    var rv=navigator.userAgent.indexOf("rv:11.0");

    if (ieold) iev=new Number(RegExp.$1);
    if (navigator.appVersion.indexOf("MSIE 10") != -1) iev=10;
    if (trident&&rv!=-1) iev=11;

    return iev;         
}

물론 0을 반환하면 IE가 없음을 의미합니다.

User-Agent에서 IE 버전 가져 오기

var ie = 0;
try { ie = navigator.userAgent.match( /(MSIE |Trident.*rv[ :])([0-9]+)/ )[ 2 ]; }
catch(e){}

How it works: The user-agent string for all IE versions includes a portion "MSIE space version" or "Trident other-text rv space-or-colon version". Knowing this, we grab the version number from a String.match() regular expression. A try-catch block is used to shorten the code, otherwise we'd need to test the array bounds for non-IE browsers.

Note: The user-agent can be spoofed or omitted, sometimes unintentionally if the user has set their browser to a "compatibility mode". Though this doesn't seem like much of an issue in practice.

Get IE Version without the User-Agent

var d = document, w = window;
var ie = ( !!w.MSInputMethodContext ? 11 : !d.all ? 99 : w.atob ? 10 : 
d.addEventListener ? 9 : d.querySelector ? 8 : w.XMLHttpRequest ? 7 : 
d.compatMode ? 6 : w.attachEvent ? 5 : 1 );

How it works: Each version of IE adds support for additional features not found in previous versions. So we can test for the features in a top-down manner. A ternary sequence is used here for brevity, though if-then and switch statements would work just as well. The variable ie is set to an integer 5-11, or 1 for older, or 99 for newer/non-IE. You can set it to 0 if you just want to test for IE 1-11 exactly.

Note: Object detection may break if your code is run on a page with third-party scripts that add polyfills for things like document.addEventListener. In such situations the user-agent is the best option.

Detect if the Browser is Modern

If you're only interested in whether or not a browser supports most HTML 5 and CSS 3 standards, you can reasonably assume that IE 8 and lower remain the primary problem apps. Testing for window.getComputedStyle will give you a fairly good mix of modern browsers, as well (IE 9, FF 4, Chrome 11, Safari 5, Opera 11.5). IE 9 greatly improves on standards support, but native CSS animation requires IE 10.

var isModernBrowser = ( !document.all || ( document.all && document.addEventListener ) );

Angular JS does this way.

msie = parseInt((/msie (\d+)/.exec(navigator.userAgent.toLowerCase()) || [])[1]);
if (isNaN(msie)) {
  msie = parseInt((/trident\/.*; rv:(\d+)/.exec(navigator.userAgent.toLowerCase()) || [])[1]);
}

msie will be positive number if its IE and NaN for other browser like chrome,firefox.

why ?

As of Internet Explorer 11, the user-agent string has changed significantly.

refer this :

msdn #1 msdn #2

solution :

function GetIEVersion() {
  var sAgent = window.navigator.userAgent;
  var Idx = sAgent.indexOf("MSIE");
  // If IE, return version number.
  if (Idx > 0)
    return parseInt(sAgent.substring(Idx+ 5, sAgent.indexOf(".", Idx)));

  // If IE 11 then look for Updated user agent string.
  else if (!!navigator.userAgent.match(/Trident\/7\./))
    return 11;

  else
    return 0; //It is not IE

}
if ((GetIEVersion() > 0) || (navigator.userAgent.toLowerCase().indexOf('firefox') > -1)){
  alert("This is IE " + GetIEVersion());
}else {
  alert("This no is IE ");
}

I'm using a simpler method:

The navigator global object has a property touchpoints, in Internet Exlorer 11 is called msMaxTouchPoints tho.

So if you look for:

navigator.msMaxTouchPoints !== void 0

You will find Internet Explorer 11.

var ua = navigator.userAgent.toString().toLowerCase();
var match = /(trident)(?:.*rv:([\w.]+))?/.exec(ua) ||/(msie) ([\w.]+)/.exec(ua)||['',null,-1];
var rv = match[2];
return rv;

Try This:

var trident = !!navigator.userAgent.match(/Trident\/7.0/);
var net = !!navigator.userAgent.match(/.NET4.0E/);
var IE11 = trident && net
var IEold = ( navigator.userAgent.match(/MSIE/i) ? true : false );
if(IE11 || IEold){
alert("IE")
}else{
alert("Other")
}

This appears to be a better method. "indexOf" returns -1 if nothing is matched. It doesn't overwrite existing classes on the body, just adds them.

// add a class on the body ie IE 10/11
var uA = navigator.userAgent;
if(uA.indexOf('Trident') != -1 && uA.indexOf('rv:11') != -1){
    document.body.className = document.body.className+' ie11';
}
if(uA.indexOf('Trident') != -1 && uA.indexOf('MSIE 10.0') != -1){
    document.body.className = document.body.className+' ie10';
}

Detect most browsers with this:

var getBrowser = function(){
  var navigatorObj = navigator.appName,
      userAgentObj = navigator.userAgent,
      matchVersion;
  var match = userAgentObj.match(/(opera|chrome|safari|firefox|msie|trident)\/?\s*(\.?\d+(\.\d+)*)/i);
  if( match && (matchVersion = userAgentObj.match(/version\/([\.\d]+)/i)) !== null) match[2] = matchVersion[1];
  //mobile
  if (navigator.userAgent.match(/iPhone|Android|webOS|iPad/i)) {
    return match ? [match[1], match[2], mobile] : [navigatorObj, navigator.appVersion, mobile];
  }
  // web browser
  return match ? [match[1], match[2]] : [navigatorObj, navigator.appVersion, '-?'];
};

I used the onscroll event at the element with the scrollbar. When triggered in IE, I added the following validation:

onscroll="if (document.activeElement==this) ignoreHideOptions()"

Only for IE Browser:

var ie = 'NotIE'; //IE5-11, Edge+
    if( !!document.compatMode ) {
        if( !("ActiveXObject" in window) ) ) ie = 'EDGE';
        if( !!document.uniqueID){
            if('ActiveXObject' in window && !window.createPopup ){ ie = 11; }
            else if(!!document.all){
                    if(!!window.atob){ie = 10;}
                    else if(!!document.addEventListener) {ie = 9;}
                    else if(!!document.querySelector){ie = 8;}
                    else if(!!window.XMLHttpRequest){ie = 7;}
                    else if(!!document.compatMode){ie = 6;}
                    else ie = 5;
                }
        }
    }

use alert(ie);

Testing:

var browserVersionExplorer = (function() {
    var ie = '<s>NotIE</s>',
        me = '<s>NotIE</s>';

    if (/msie\s|trident\/|edge\//i.test(window.navigator.userAgent) && !!(document.documentMode || document.uniqueID || window.ActiveXObject || window.MSInputMethodContext)) {
            if (!!window.MSInputMethodContext) {
                ie = !("ActiveXObject" in window) ? 'EDGE' : 11;
            } else if (!!document.uniqueID) {
                if (!!(window.ActiveXObject && document.all)) {
                    if (document.compatMode == "CSS1Compat" && !!window.DOMParser ) {
                        ie = !!window.XMLHttpRequest ? 7 : 6;
                    } else {
                        ie = !!(window.createPopup && document.getElementById) ? parseFloat('5.5') : 5;
                    }
                    if (!!document.documentMode && !!document.querySelector ) {
                        ie = !!(window.atob && window.matchMedia) ? 10 : ( !!document.addEventListener ? 9 : 8);
                    }
                } else ie = !!document.all ? 4 : (!!window.navigator ? 3 : 2);
            }
        }
        
    return ie > 1 ? 'IE ' + ie : ie;
})();

 alert(browserVersionExplorer);

Update 01 Jun 2017

Now we could use something easier and simpler:

var uA = window.navigator.userAgent,
    onlyIEorEdge = /msie\s|trident\/|edge\//i.test(uA) && !!( document.uniqueID || window.MSInputMethodContext),
    checkVersion = (onlyIEorEdge && +(/(edge\/|rv:|msie\s)([\d.]+)/i.exec(uA)[2])) || NaN;

Quite frankly I would say use a library that does what you need (like platform.js for example). At some point things will change and the library will be equipped for those changes and manual parsing using regular expressions will fail.

Thank god IE goes away...
