Introduction

Source can be loaded via npm, bower or downloaded from this repo.

# npm package

# bower
$ bower install nwc-i18next

Simplifies i18next usage in projects using native web components, like:

page source:

<ul class="nav">
  <li><a href="#" data-i18n="nav.home"></a></li>
  <li><a href="#" data-i18n="nav.page1"></a></li>
  <li><a href="#" data-i18n="nav.page2"></a></li>
</ul>

loaded resource file (locales/en/translation.json):

{
  "nav": {
    "home": "Home",
    "page1": "Page One",
    "page2": "Page Two"
  }
}

javascript code:

$(".nav").localize();

// results in
// <ul class="nav">
//  <li><a href="#" data-i18n="nav.home">Home</a></li>
//  <li><a href="#" data-i18n="nav.page1">Page One</a></li>
//  <li><a href="#" data-i18n="nav.page2">Page Two</a></li>
// </ul>

Initialize the plugin

nwcI18next.init(i18nextInstance, $, {
  tName: 't', // --> appends $.t = i18next.t
  i18nName: 'i18n', // --> appends $.i18n = i18next
  handleName: 'localize', // --> appends $(selector).localize(opts);
  selectorAttr: 'data-i18n', // selector for translating elements
  targetAttr: 'i18n-target', // data-() attribute to grab target element to translate (if diffrent then itself)
  optionsAttr: 'i18n-options', // data-() attribute that contains options, will load/set if useOptionsAttr = true
  useOptionsAttr: false, // see optionsAttr
  parseDefaultValueFromContent: true // parses default values from content ele.val or ele.text
});

using options in translation function

<a id="btn1" href="#" data-i18n="myKey"></a>
$("#btn1").localize(options);

or

<a id="btn1" href="#" data-i18n="myKey" data-i18n-options="{ 'a': 'b' }"></a>
$("#btn1").localize();

usage of selector function

translate an element

<a id="btn1" href="#" data-i18n="myKey"></a>
$("#btn1").localize(options);

myKey: same key as used in i18next (optionally with namespaces) options: same options as supported in i18next.t

translate children of an element

<ul class="nav">
  <li><a href="#" data-i18n="nav.home"></a></li>
  <li><a href="#" data-i18n="nav.page1"></a></li>
  <li><a href="#" data-i18n="nav.page2"></a></li>
</ul>
$(".nav").localize();

translate some inner element

<div class="outer" data-i18n="ns:key" data-i18n-target=".inner">
  <input class="inner" type="text"></input>
</div>
$(".outer").localize();

set different attribute

<a id="btn1" href="#" data-i18n="[title]key.for.title"></a>
$("#btn1").localize();

set multiple attributes

<a id="btn1" href="#" data-i18n="[title]key.for.title;myNamespace:key.for.text"></a>
$("#btn1").localize();

set innerHtml attributes

<a id="btn1" href="#" data-i18n="[html]key.for.title"></a>
$("#btn1").localize();

prepend content

<a id="btn1" href="#" data-i18n="[prepend]key.for.title">insert before me, please!</a>
$("#btn1").localize();

append content

<a id="btn1" href="#" data-i18n="[append]key.for.title">append after me, please!</a>
$("#btn1").localize();

set data

<a id="btn1" href="#" data-i18n="[data-someDataAttribute]key.for.content"></a>
$("#btn1").localize();
