/* pathnamereplace.js v0.1.3, URL pathname replace for conditional redirects to support multi-language sites, now with cookies and passtrue list.
|
|||
|
|
* Author & copyright (c) 2017: Göran Svensson, goran@molnsys.com. MIT license.
|
|||
|
|
* Tested with Chrome 36, Firefox 29 and Safari 7.0.5 on OSX.
|
|||
|
|
* Tested with Chrome 36 on Xperia V (Android 4.3) and Internet 2.3.6 on Samsung GT-S5360 (Android 2.3.6).
|
|||
|
|
* Works with any number of path name items and language acronymes. Does not break the back button.
|
|||
|
|
* How to use it; add this in your nav menu: javascript:changeLanguage('se') to switch to swedish version.
|
|||
|
|
* REQUIRES: JavaScript Cookie v2.1.4 https://github.com/js-cookie/js-cookie
|
|||
|
|
|
|||
|
|
*CatalystScripts/Java_Cookies.js and country = '{module_visitorcountrycode}'; added
|
|||
|
|
* above this script (does not work inside a js file).
|
|||
|
|
* No bugs have been harmed.
|
|||
|
|
* To avoid unnecesary reload, build a nav menu for each language with the right path.
