| -/**
|
| - * @fileoverview This is a simple template engine inspired by JsTemplates
|
| - * optimized for i18n.
|
| - *
|
| - * It currently supports three handlers:
|
| - *
|
| - * * i18n-content which sets the textContent of the element.
|
| - *
|
| - * <span i18n-content="myContent"></span>
|
| - *
|
| - * * i18n-options which generates <option> elements for a <select>.
|
| - *
|
| - * <select i18n-options="myOptionList"></select>
|
| - *
|
| - * * i18n-values is a list of attribute-value or property-value pairs.
|
| - * Properties are prefixed with a '.' and can contain nested properties.
|
| - *
|
| - * <span i18n-values="title:myTitle;.style.fontSize:fontSize"></span>
|
| - *
|
| - * This file is a copy of i18n_template.js, with minor tweaks to support using
|
| - * load_time_data.js. It should replace i18n_template.js eventually.
