TypeScript
// This example retrieves autocomplete predictions programmatically from the// autocomplete service, and displays them as an HTML list.// This example requires the Places library. Include the libraries=places// parameter when you first load the API. For example:// <script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places">functioninitService():void{constdisplaySuggestions=function(predictions:google.maps.places.QueryAutocompletePrediction[]|null,status:google.maps.places.PlacesServiceStatus){if(status!=google.maps.places.PlacesServiceStatus.OK||!predictions){alert(status);return;}predictions.forEach((prediction)=>{constli=document.createElement("li");li.appendChild(document.createTextNode(prediction.description));(document.getElementById("results")asHTMLUListElement).appendChild(li);});};constservice=newgoogle.maps.places.AutocompleteService();service.getQueryPredictions({input:"pizza near Syd"},displaySuggestions);}declareglobal{interfaceWindow{initService:()=>void;}}window.initService=initService;
