经过一番研究;事实证明,使用数据源无法做到这一点,而是使用 AJAX ( $.ajax()
) 与 Sling Servlet 通信以实现必要的功能。

我使用此文档作为执行功能的基础,但根据我的规范进行了调整。
(function ($, $document) {
"use strict";
var LANGUAGE = "./language", COUNTRY = "./country";
function adjustLayoutHeight(){
$(".coral-FixedColumn-column").css("height", "20rem");
}
$document.on("dialog-ready", function() {
adjustLayoutHeight();
// Getting reference of language drop down field
var language = $("[name='" + LANGUAGE +"']").closest(".coral-Select")
// Initializing country drop down field
var country = new CUI.Select({
element: $("[name='" + COUNTRY +"']").closest(".coral-Select")
});
if(_.isEmpty(country) || _.isEmpty(language)){
return;
}
var langCountries = {};
country._selectList.children().not("[role='option']").remove();
function fillCountries(selectedLang, selectedCountry){
var x = $("[name='./country']").closest(".coral- Select").find('option').remove().end();
_.each(langCountries, function(value, lang) {
if( (lang.indexOf(selectedLang) !== 0) || (value.country == "*") ){
return;
}
var test2 = $("[name='./country']")[0];
$("<option>").appendTo(test2).val(lang).html(value.country);
});
country = new CUI.Select({
element: $("[name='" + COUNTRY +"']").closest(".coral-Select")
});
if(!_.isEmpty(selectedCountry)){
country.setValue(selectedCountry);
}
}
//listener on language select for dynamically filling the countries on language select
language.on('selected.select', function(event){
console.log(event);
fillCountries(event.selected);
});
// Get the languages list from the source
$.getJSON("/libs/wcm/core/resources/languages.2.json").done(function(data){
langCountries = data;
var $form = country.$element.closest("form");
//get the second select box (country) saved value
$.getJSON($form.attr("action") + ".json").done(function(data){
if(_.isEmpty(data)){
return;
}
// Passing values to populate countries list
fillCountries(language.val(), data.country);
})
});
});
})($, $(document));
