Fancybox doesn’t work with jQuery v1.9.0 [ f.browser is undefined / Cannot read property ‘msie’ ]

It seems like it exists a bug in jQuery reported here : http://bugs.jquery.com/ticket/13183 that breaks the Fancybox script.

Also check https://github.com/fancyapps/fancyBox/issues/485 for further reference.

As a workaround, rollback to jQuery v1.8.3 while either the jQuery bug is fixed or Fancybox is patched.


UPDATE (Jan 16, 2013): Fancybox v2.1.4 has been released and now it works fine with jQuery v1.9.0.

For fancybox v1.3.4- you still need to rollback to jQuery v1.8.3 or apply the migration script as pointed out by @Manu’s answer.


UPDATE (Jan 17, 2013): Workaround for users of Fancybox v1.3.4 :

Patch the fancybox js file to make it work with jQuery v1.9.0 as follow :

  1. Open the jquery.fancybox-1.3.4.js file (full version, not pack version) with a text/html editor.
  2. Find around the line 29 where it says :

    isIE6 = $.browser.msie && $.browser.version < 7 && !window.XMLHttpRequest,
    

    and replace it by (EDITED March 19, 2013: more accurate filter):

    isIE6 = navigator.userAgent.match(/msie [6]/i) && !window.XMLHttpRequest,
    

    UPDATE (March 19, 2013): Also replace $.browser.msie by navigator.userAgent.match(/msie [6]/i) around line 615 (and/or replace all $.browser.msie instances, if any), thanks joofow
    … that’s it!

Or download the already patched version from HERE (UPDATED March 19, 2013 … thanks fairylee for pointing out the extra closing bracket)

NOTE: this is an unofficial patch and is unsupported by Fancybox’s author, however it works as is. You may use it at your own risk 😉

Optionally, you may rather rollback to jQuery v1.8.3 or apply the migration script as pointed out by @Manu’s answer.
