drop down population based on locale (sightly AEM) - sightly

Question

I am new to AEM, consider my js would return itemList (for ex: var itemList = list.getItems();).
The skeleton of each Item would be:
interface Item {
/**
* Get the item's title.
*
* #return the title
*/
#Nonnull
String getTitle();
/**
* Get the item's localized title.
*
* #param locale the locale for localization
*
* #return the title
*/
#Nonnull
String getTitle(Locale locale);
/**
* Get the item's value.
*
* #return the value
*/
#Nonnull
String getValue();
}
How can I get the locale based title (i.e calling getTitle(locale)) in place of ${list.title} mentioned in the below HTML code of select tag (I need both title(locale) and value in the itemlist):
option value="${list.value}">${list.title}

Answer 1

From Sightly, you cannot access methods with parameters.
However, in the Use-API, the same global variables are available as in the Sightly execution context, and you can also pass parameters to the initialization of the Use-API.
In Java code, you can for instance access the page language with something like that:
PageManager pageManager = request.getResourceResolver().adaptTo(PageManager.class);
Page currentPage = pageManager.getContainingPage(request.getResource());
Locale locale = currentPage.getLanguage(false);
Else, to pass parameters to the Java Use-API, this is how it goes:
<div data-sly-use.foo="${'Foo' # locale='es'}">
<h1>${foo.titleLocalized}</h1>
</div>
And the corresponding Java:
public class Foo extends WCMUsePojo {
private String locale;
#Override
public void activate() throws Exception {
String locale = get("locale", String.class);
}
public String titleLocalized() {
...
}
}
