how to get browser language via script include or function call

[Eleven_TW]

gs.getSession().getLanguage() will retrieve current session pre-defined language but I want to get browser langugage/language code as kind of backup.

navigator.language || navigator.userLanguage seems like not working since it will show error of navigator is not defined.

also tried to create a new class of script include, but seems like not working either as following:

var BrowserLocaleUtil = Class.create();
BrowserLocaleUtil.prototype = {
    initialize: function() {},

    getBrowserLocale: function(request) {
    var acceptLanguage = request.getHeader('Accept-Language');

    if (acceptLanguage) {
        var languageTag = acceptLanguage.split(',')[0];

        return languageTag;
    } else {
        return 'en';
    }
},

type: 'BrowserLocaleUtil'
};

and call in other script
var browserLocaleUtil = new BrowserLocaleUtil();

var browserLocale = browserLocaleUtil.getBrowserLocale(current.request);

Please help any JavaScript functions to retrieve the browser language code since there is potential missing from either service now user table or current session language set.

In the code above request is not defined.

Use GlideTransaction.get().getRequest() in place of request.

Also I would change acceptLanguage.split(',')[0] into acceptLanguage.split(',').shift().

Just wanted to add that this will only work in global scope - so make sure the Script Include is defined in global scope and is marked as accessible from all scopes.

Hi -O-,

Thank you so much for your details.

Everything works fine in background script, I can get locale using the following:

var acceptLanguage = GlideTransaction.get().getRequest().getHeader('Accept-Language');

var locale = acceptLanguage.split(',').shift();

gs.info(acceptLanguage);

=> 

*** Script: en-US,en;q=0.9

But after I created global script include as following:

and call it in my application script include via:

var browserUtils = new global.BrowserUtils();
var expectedLocale =  browserUtils.getBrowserLocale();

It shows error:

*** Script: Falied to get browser locale {"message":"Cannot convert null to an object.","rhinoException":{}}: no thrown error

Thanks in advance for your help!
