Get UI language name in javascript

Question

I need to get the name of the current UI language in a javascript file. I know the following trick:

SP.Res.lcid

But that gets the the LCID. What I really need is the two-letter iso name (like 'en', 'fr', etc)

Answer 1

You can create a JS object and fetch the values using the LCID:

var CultureNames = { 1033:"en", 1036:"fr" };//Store it in a utility file somewhere.

var currentCultureName = CultureNames[SP.Res.lcid]; //will return 'en' if current culture is english.
