How to add translatable string in function parameter?

Question

I have a javascript function in a wordpress script, I need it to be compatible with WPML chain translation

ubp_show_error("<p>Inutile de l'ajouter plusieurs fois</p>");

How can I make this chain to be something like this :

ubp_show_error(_e('<p>Inutile de l'ajouter plusieurs fois</p>','mytheme'));

I've tryed :

$error = _('<p>Inutile de l'ajouter plusieurs fois</p>','mytheme');
ubp_show_error($error); 

but in javascript, this doesn't work

You need to localize your script.

PHP

function custom_load_scripts() {
    wp_enqueue_script('your-script', '/your-script.js');
    wp_localize_script('your-script', 'your_js_obj_name', array(
            'error' => __("<p>Inutile de l'ajouter plusieurs fois</p>",'mytheme')
        )
    );
}
add_action('wp_enqueue_scripts', 'custom_load_scripts');

Now you have access to that data in your javascript file like:

JS

your_js_obj_name.error // --> '<p>Inutile de l'ajouter plusieurs fois</p>'
