JavaScript and XPages reference
This reference describes the JavaScript™ language elements, Application Programming Interfaces (APIs), and other artifacts that you need to create scripts, plus the XPages simple actions.
Runtime (JavaScript)
The Runtime library contains classes that provide useful methods for globalization.
Locale (Runtime - JavaScript)
A Locale object represents a specific geographical, political, or cultural region. An operation that requires a Locale to perform its task is called locale-sensitive and uses the Locale to tailor information for the user. For example, displaying a number is a locale-sensitive operation because the number should be formatted according to the conventions of the user's native country, region, or culture.
getDisplayLanguage (JavaScript)
Returns a name for the locale's language that is appropriate for display to the user.

getDisplayLanguage (JavaScript)

Returns a name for the locale's language that is appropriate for display to the user.

If possible, the name returned will be localized according to Locale. For example, if the locale is fr_FR and Locale is en_US, getDisplayLanguage() will return "French"; if the locale is en_US and inLocale is fr_FR, getDisplayLanguage() will return "anglais". If the name returned cannot be localized according to inLocale, (say, there is no Japanese name for Croatian), this function falls back on the default locale, on the English name, and finally on the ISO code as a last-resort value. If the locale doesn't specify a language, this function returns the empty string.
