Question

We can config in Magento to set locale language and using function $this->__(string $test) to translate.

How about this feature but for javascript? For example, when I use validation.js and when getting some errors it will show the message with the locale language which I set.

The validation.js file is located at: src/js/prototype/prototype.js

In inside the file we will see something:

Validation.addAllThese([
    ['validate-select', 'Please select an option.', function(v) {
                return ((v != "none") && (v != null) && (v.length != 0));
            }],
    ['required-entry', 'This is a required field.', function(v) {
                return !Validation.get('IsEmpty').test(v);
            }],
    ['validate-number', 'Please enter a valid number in this field.', function(v) {
                return Validation.get('IsEmpty').test(v) || (!isNaN(parseNumber(v)) && !/^\s+$/.test(parseNumber(v)));
            }]
]

So, how could I translate the messages This is a required field.,Please select an option.?

I’m not sure if that’s what you’re asking, but the translations of th javascript messages are set in app/code/Core/Mage/Core/Helper/Js.php -> _getTranslateData() and is called in app/design/package/ theme/template/page/html/head.phtml <?php echo $this->helper('core/js')->getTranslatorScript() ?>

I’ve just need that myself, let me refrase:

1. in the phtml you add the strings you need to translate:

   <script type="text/javascript">
       //<![CDATA[
           Translator.add('String to translate', '<?php echo $this->__('String to translate'); ?>');
       //]]>
   </script>
   

2. in your javascript file, use:

   Translator.translate('String to translate');
   

3. now you can use your csv translations files
