該處地圖API（3.0）
爲JavaScript新的3.0該處地圖API是很好的模塊化的，並完全支持異步加載。例如，它可能使用requirejs如下加載一個簡單的地圖：
require(['mapsjsService','mapsjsEvents', 'mapsjsUi'], function() {
var platform = new H.service.Platform({
app_id: '<YOUR APP ID>',
app_code: '<YOUR TOKEN>'
});
var defaultLayers = platform.createDefaultLayers();
var map = new H.Map(document.getElementById('map'),
defaultLayers.normal.map);
var behavior = new H.mapevents.Behavior(new H.mapevents.MapEvents(map));
var ui = H.ui.UI.createDefault(map, defaultLayers);
});
配置文件需要如下被分配：
requirejs.config({
baseUrl: '.',
waitSeconds: 0,
map: {
'*': {
'css': 'require-css' // or whatever the path to require-css is
}
},
paths: {
'mapsjsCore' : 'https://js.api.here.com/v3/3.0/mapsjs-core',
'mapsjsService' : 'https://js.api.here.com/v3/3.0/mapsjs-service',
'mapsjsEvents' : 'https://js.api.here.com/v3/3.0/mapsjs-mapevents',
'mapsjsUi' :'https://js.api.here.com/v3/3.0/mapsjs-ui',
'mapsjsCss' :'https://js.api.here.com/v3/3.0/mapsjs-ui',
},
shim: {
'mapsjsService': {
deps: ['mapsjsCore']
},
'mapsjsEvents': {
deps: ['mapsjsCore']
},
'mapsjsUi': {
deps: ['mapsjsCore', 'css!mapsjsCss']
}
}
});
如可以看到的，所有的模塊依賴於mapsjsCore，但是沒有一個子模塊依賴於彼此。 mapsjsUi是一個特殊情況，因爲它具有用於默認外觀的關聯CSS文件。您可以在標題中保存默認CSS（或覆蓋），或者使用requirejs插件（如require-css）加載它。需要注意的是，在配置中需要使用waitSeconds:0這一行，以避免在將第一次下載HERE Maps for JavaScript庫到瀏覽器時發生超時，因爲它們不會在本地找到，所以您依賴於速度您的互聯網連接至少一次。
或者用jQuery的：
$.getScript('https://js.api.here.com/v3/3.0/mapsjs-core.js', function() {
$.getScript('https://js.api.here.com/v3/3.0/mapsjs-service.js', function() {
$.getScript('https://js.api.here.com/v3/3.0/mapsjs-mapevents.js', function() {
$.getScript('https://js.api.here.com/v3/3.0/mapsjs-mapevents.js', function() {

JavaScript的諾基亞地圖API（2.2.4-2.5.4）
的最近棄用的版本Nokia Maps API for JavaScript（版本2.2.4及更高版本）支持異步加載，如下所示

你好，我正在開發一個應用程序與MH5集成iOS和Android諾基亞地圖。我想有一個可拖動的標記，所以它是可能在mh5或jHERE插件 – user869123
