When this happens, the value of navigator.language is changed (or should be!). It would be nice if HTML provided some means to be notified that the change had taken place. The application can then use this information to perform appropriate localization changes on the client side. For example, reformatting DOM elements that contain times and dates to better suit the new locale information (this could work together with the ECMAScript i18n API). 84443 1 w3c 2013-03-14 19:40:58 +0000 See also: http://lists.w3.org/Archives/Public/public-sysapps/2013Mar/0097.html FireFox OS has a mutation observer that watches for changes in "language.current" of "navigator.mozSettings": navigator.mozSettings.addObserver('language.current', function(event) { … }); Blackberry also has an event for this: http://developer.blackberry.com/html5/api/blackberry.system.html#.event:languagechanged 84494 2 mounir 2013-03-15 22:59:42 +0000 There were some ideas to push a Web l10n specification that would add a 'locale-change' event (or something similar) fired to the document object. I am not sure how such a specification would be followed though. 84936 3 mounir 2013-03-25 18:27:55 +0000 For the record, Firefox OS is using this: https://github.com/fabi1cazenave/webL10n 86974 4 ian 2013-04-29 23:40:36 +0000 This would be easy to spec if anyone wants to implement it. Who wants to implement it? See also bug 17859. 86997 5 w3c 2013-04-30 10:26:19 +0000 Mozilla has expressed interest in implementing. 87006 6 mounir 2013-04-30 14:46:15 +0000 Yes, we are interested, at least in an application context (like Firefox OS) where such a feature would be very useful. 88565 7 bugs 2013-06-03 09:32:22 +0000 *** Bug 22242 has been marked as a duplicate of this bug. *** 109146 8 ian 2014-07-21 20:57:47 +0000 There's a "languagechange" event that fires at Window when navigator.languages change. Language and locale are different, but since currently we don't expose any locale stuff, it might be a moot point... 112429 9 ian 2014-09-29 23:36:11 +0000 I'm marking this WORKSFORME since the actual request has been done. I'm sure if we add locale stuff that we'll add locale change notifications as part of it.
