ExposeTranslationBundle[Symfony2] A pretty nice way to expose your translation messages to your JavaScript. | |
| Resources/public/js/translation.js |
|
Define Translation class.
|
$.ExposeTranslation = $.ExposeTranslation || {};
(function(Translation, $, undefined) {
$.extend(Translation, (function() {
var _messages = {},
_sPluralRegex = /^\w+\: +(.+)$/,
_cPluralRegex = /^(({\s*(\-?\d+[\s*,\s*\-?\d+]*)\s*})|([\[\]])\s*(-Inf|\-?\d+)\s*,\s*(\+?Inf|\-?\d+)\s*([\[\]]))\s+(.+?)$/,
_iPluralRegex = /^({\s*(\-?\d+[\s*,\s*\-?\d+]*)\s*})|([\[\]])\s*(-Inf|\-?\d+)\s*,\s*(\+?Inf|\-?\d+)\s*([\[\]])/;

Guess the domain if you don't specify it, based on
given default domains.

function guess_domain(key) {
var _k,
_key = key,
_defaultDomains = Translation.defaultDomains;

The logic comes from the Symfony2 PHP Framework.
Given a message with different plural translations separated by a
pipe (|), this method returns the correct portion of the message based
on the given number, the current locale and the pluralization rules
in the message itself.
The message supports two different types of pluralization rules:
interval: {0} There is no apples|{1} There is one apple|]1,Inf] There is %count% apples
indexed: There is one apple|There is %count% apples
The indexed solution can also contain labels (e.g. one: There is one apple).
This is purely for making the translations more clear - it does not
affect the functionality.
The two methods can also be mixed:
{0} There is no apples|one: There is one apple|more: There is %count% apples
param: String message The message. param: Number number The number. return: String The message part to use for translation. api: private

values to number values.
