browser.msie error after update to jQuery 1.9.1

I use the following snip of a script:

if ($.browser.msie && $.browser.version < 9) {
   extra = "?" + Math.floor(Math.random() * 3000);
}

It works fine with jQuery 1.8.3.

Now I updated jQuery to the new version 1.9.1 to use a new script.
Now I get the following error:

TypeError: Cannot read property 'msie' of undefined

I read the change log of the new jQuery version, but nothing should have changed
with msie

Any known bugs, tips or proposals?

$.browser was deprecated in version 1.3 and removed in 1.9

You can verify this by viewing the documentation.

Since $.browser is deprecated, here is an alternative solution:

/**
 * Returns the version of Internet Explorer or a -1
 * (indicating the use of another browser).
 */
function getInternetExplorerVersion()
{
    var rv = -1; // Return value assumes failure.

    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 )
    {
        if ( ver >= 8.0 ) 
            msg = "You're using a recent copy of Internet Explorer."
        else
            msg = "You should upgrade your copy of Internet Explorer.";
    }

    alert( msg );
}

However, the reason that its deprecated is because jQuery wants you to use feature detection instead.

An example:

$("p").html("This frame uses the W3C box model: <span>" +
        jQuery.support.boxModel + "</span>");

And last but not least, the most reliable way to check IE versions:

// ----------------------------------------------------------
// A short snippet for detecting versions of IE in JavaScript
// without resorting to user-agent sniffing
// ----------------------------------------------------------
// If you're not in IE (or IE version is less than 5) then:
//     ie === undefined
// If you're in IE (>=5) then you can determine which version:
//     ie === 7; // IE7
// Thus, to detect IE:
//     if (ie) {}
// And to detect the version:
//     ie === 6 // IE6
//     ie > 7 // IE8, IE9 ...
//     ie < 9 // Anything less than IE9
// ----------------------------------------------------------

// UPDATE: Now using Live NodeList idea from @jdalton

var ie = (function(){

    var undef,
        v = 3,
        div = document.createElement('div'),
        all = div.getElementsByTagName('i');

    while (
        div.innerHTML = '<!--[if gt IE ' + (++v) + ']><i></i><![endif]-->',
        all[0]
    );

    return v > 4 ? v : undef;

}());

The jQuery.browser options was deprecated earlier and removed in 1.9 release along with a lot of other deprecated items like .live.

For projects and external libraries which want to upgrade to 1.9 but still want to support these features jQuery have release a migration plugin for the time being.

If you need backward compatibility you can use migration plugin.

For simple IE detection I tend to use:

(/msie|trident/i).test(navigator.userAgent)

Visit the Microsoft Developer Network to learn about the IE useragent: http://msdn.microsoft.com/library/ms537503.aspx

Include jQuery migration plugin along with your jQuery library.

Update! Complete answer overhaul for new plugin!

The following plugin has been tested in all major browsers. It makes traditional use of userAgent string to re-equip jQuery.browser only if you're using jQuery version 1.9 or Greater!

It has the traditional jQuery.browser.msie type properties as well as a few new ones, including a .mobile property to help decide if user is on a mobile device.

Note: _{This is not a suitable replacement for feature testing. If you expect to support a specific feature on a specific device, it's still best to use traditional feature testing}

You can detect the IE browser by this way.

(navigator.userAgent.toLowerCase().indexOf('msie 6') != -1)

you can get reference on this URL: jquery.browser.msie Alternative

Using this:

if (navigator.userAgent.match("MSIE")) {}

You can use :

var MSIE = jQuery.support.leadingWhitespace; // This property is not supported by ie 6-8

$(document).ready(function(){

if (MSIE){
    if (navigator.vendor == 'Apple Computer, Inc.'){
        // some code for this navigator
    } else {
       // some code for others browsers
    }

} else {
    // default code

}});

Instead of having the whole migration script added, you could simply add the following (extracted from the migration script)

$.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 ) ||
        [];

    return {
        browser: match[ 1 ] || "",
        version: match[ 2 ] || "0"
    };
};

and then use it like so

$.uaMatch(navigator.userAgent)

I had this problem as well. We were using two versions of Jquery (1.11.3 and 1.8.3), one of which was causing this issue. I found a lightbox_me.js release that worked on both versions:

It was just an easy replacement of an old file.
