| 18 | <h1>using string bundles with JavaScript</h1> |
| 19 | |
| 20 | <div class="explanation"> |
| 21 | For localization of text that gets displayed with JavaScript, there are <b>multiple techniques</b>. |
| 22 | First, we could use <b><data>&some.text;</data></b> constructs (which don't get displayed in the UI), |
| 23 | read their values from JS and use them for displaying. This isn't a very elegant solution though. |
| 24 | <br>The normal solution for this situation is to use <b>string bundles</b>, which are saved in |
| 25 | Java-style <b>.properties</b> files. String bundles can be accessed in two ways: First, they can be read by a XUL |
| 26 | <b><stringbundle></b> element: |
