jQuery migration from 1.8.3 to 1.9.1 stops working in one line, and I don't know why

I was using this code:

http://labs.abeautifulsite.net/archived/jquery-alerts/demo/

And it worked fine with jQuery 1.8.3.

Now I changed to jQuery 1.9.1 and it stopped working

Most of my other codes had problems, mostly I had to change .live for .on and it was solved (I don’t know if this was the right thing to do), but with this code, I don’t find the issue.

THIS LINE SEEMS TO GIVE THE PROBLEM:

// IE6 Fix
var pos = ($.browser.msie && parseInt($.browser.version) <= 6 ) ? 'absolute' : 'fixed';

You can test it in jsFiddle and you can change to jQuery 1.8.3, to see how it works.

Use feature detection.

var someEl = $("#theid");
someEl.css("position","fixed");
if ( someEl.css("position") == "static" ) {
    // doesn't support fixed, use absolute
    someEl.css("position","absolute");
}

(not tested)

$.browser has been removed from 1.9. You can use jQuery Migrate to have $.browser support.

See previously: TypeError: 'undefined' is not an object (evaluating '$.browser.msie')

You can use the jQuery Migrate plugin and call the $.browser. It will work!

Using the plugin is easy; just include it immediately after the script tag for jQuery, for example.

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.1.1.js"></script>

JS:

$.each($.browser, function(i, val) {
  $("<div>" + i + " : <span>" + val + "</span>")
  .appendTo( document.body );
});

DEMO HERE (See Migrate 1.1.0 check box is checked on left side)

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

http://jquery.com/upgrade-guide/1.9/#jquery-browser-removed

You should use the jQuery migrate plugin to see any errors when migrating to 1.9x. Also, jQuery recommends using feature detection with a library such as Modernizr.
