This article is translated from: Check if user is using IE

I am calling a function like the one below by clicking on div s with a certain class.

Is there a way I can check when starting the function if a user is using Internet Explorer and abort / cancel it if they are using other browsers so that it only runs for IE users Explorer, and abort / cancel this function when users use other browsers, so as to run only for IE users? The users here would all be on IE8 or higher versions so I would not need to cover IE7 and lower versions.

If I could tell which browser they are using that would be great but is not required.

Example function: example function:

$('.myClass').on('click', function(event)
{
    // my function
});

You can use $.browser to get name, vendor and version information.

See http://api.jquery.com/jQuery.browser/ See http://api.jquery.com/jQuery.browser/

#3rd floor

You can use the Navigator object to detect user navigator, you don't need jquery for it

<script type="text/javascript">

if (/MSIE (\d+\.\d+);/.test(navigator.userAgent) || navigator.userAgent.indexOf("Trident/") > -1 ){ 

 // do stuff with ie-users
}

</script>

Try this if you are using jquery version > = 1.9,

var browser;
jQuery.uaMatch = function (ua) {
    ua = ua.toLowerCase();

    var match = /(chrome)[ \/]([\w.]+)/.exec(ua) ||
        /(webkit)[ \/]([\w.]+)/.exec(ua) ||
        /(opera)(?:.*version|)[ \/]([\w.]+)/.exec(ua) ||
        /(msie) ([\w.]+)/.exec(ua) || 
        ua.indexOf("compatible") < 0 && /(mozilla)(?:.*? rv:([\w.]+)|)/.exec(ua) ||
       /(Trident)[\/]([\w.]+)/.exec(ua) || [];

    return {
        browser: match[1] || "",
        version: match[2] || "0"
    };
};
// Don't clobber any existing jQuery.browser in case it's different
if (!jQuery.browser) {
    matched = jQuery.uaMatch(navigator.userAgent);
    browser = {};

    if (matched.browser) {
        browser[matched.browser] = true;
        browser.version = matched.version;
    }

    // Chrome is Webkit, but Webkit is also Safari.
    if (browser.chrome) {
        browser.webkit = true;
    } else if (browser.webkit) {
        browser.safari = true;
    }

    jQuery.browser = browser;
}

If using jQuery version < 1.9 ($. browser was removed in jQuery 1.9) use the following code instead:

$('.myClass').on('click', function (event) {
    if ($.browser.msie) {
        alert($.browser.version);
    }
});

Use below JavaScript method: use the following JavaScript methods:

function msieversion() 
{
    var ua = window.navigator.userAgent;
    var msie = ua.indexOf("MSIE ");

    if (msie > 0) // If Internet Explorer, return version number
    {
        alert(parseInt(ua.substring(msie + 5, ua.indexOf(".", msie))));
    }
    else  // If another browser, return 0
    {
        alert('otherbrowser');
    }

    return false;
}

Update: (IE 11 support) update: (IE 11 support)

function msieversion() {

    var ua = window.navigator.userAgent;
    var msie = ua.indexOf("MSIE ");

    if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./))  // If Internet Explorer, return version number
    {
        alert(parseInt(ua.substring(msie + 5, ua.indexOf(".", msie))));
    }
    else  // If another browser, return 0
    {
        alert('otherbrowser');
    }

    return false;
}

In Edge the User Agent String has changed.

/**
 * detect IEEdge
 * returns version of IE/Edge or false, if browser is not a Microsoft browser
 */
function detectIEEdge() {
    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 => return version number
       return parseInt(ua.substring(edge + 5, ua.indexOf('.', edge)), 10);
    }

    // other browser
    return false;
}

Sample usage: usage example:

alert('IEEdge ' + detectIEEdge());
