Localizer aims to simplify the usage of grunt-locales for translating purpose. Grunt-locale is a grunt plugin which helps building translation files out of your code base (html and js files), then when compiled, the javascript language file has to be included in your page. This is where localizer comes, it handles the import of language file for you, switching locale, and translating all nodes corresponding to your criterias.
... is simple as a bower package can be installed:
bower install localizer
then add a script tag in your page:
<script src="../../bower_components/localizer/localizer.js"></script>You're done!
Exposed objects are:
- Localizer a singleton class, you can instantiate it only once
- localizer reference auto exported when you instantiate Localizer
- localize can be used only after Localizer instantiation, or it'll throw an error
Localizer prototype is
<instance of Localizer> Localizer(<Object> options)
Default options are:
Localizer.prototype.options = {
// Where the pre-built javascript files will be retrieved from
localePath: 'locales/{locale}/i18n.js',
// The default locale to be used
defaultLocale: 'en_US',
// Where the script is inserted in the page
scriptAnchor: 'i18n-src',
// Called on locale change
onLocaleChange: function (locale) {}
};Alias to localize (see localize).
// import the locales/fr_FR/i18n.js file
// and update all the registered DOM
// elements with the new translation.
localizer.setLocale('fr_FR');// get the current locale in use
console.log(localizer.getLocale()); // "fr_FR"Can take either a string:
console.log(localize('Hello')); // "Bonjour"... or a DOM element:
<h1 data-localize>Hello</h1>
<script>
var title = document.querySelector('h1');
localize(title);
console.log(title.textContent); // "Bonjour"
</script>If you have many more dom content to translate, you can also call localize on a parent ancestor:
<body>
<h1 data-localize>Hello</h1>
<h1 data-localize>Hello again</h1>
<script>
localize(document.body);
var title = document.querySelectorAll('h1').item(0);
console.log(title.textContent); // "Bonjour"
</script>
</body>When you give a DOM element to the localize method, it registers the element to be changed on the fly if language change:
<h1 data-localize>Hello</h1>
<script>
localizer.setLocale('fr_FR');
var title = document.querySelector('h1');
localize(title);
console.log(title.textContent); // "Bonjour"
localizer.setLocale('en_US');
console.log(title.textContent); // "Hello"
</script>To try out a full example of localizer capabilities, open ./examples/index.html in your web browser.
