Để tải các thư viện hỗ trợ Bộ công cụ giao diện người dùng của Địa điểm, trước tiên, hãy tải Maps JavaScript API bằng cách thêm trình tải khởi động cùng dòng vào mã ứng dụng, như minh hoạ trong đoạn mã sau:
<script> (g=>{varh,a,k,p="The Google Maps JavaScript API",c="google",l="importLibrary",q="__ib__",m=document,b=window;b=b[c]||(b[c]={});vard=b.maps||(b.maps={}),r=newSet,e=newURLSearchParams,u=()=>h||(h=newPromise(async(f,n)=>{await(a=m.createElement("script"));e.set("libraries",[...r]+"");for(king)e.set(k.replace(/[A-Z]/g,t=>"_"+t[0].toLowerCase()),g[k]);e.set("callback",c+".maps."+q);a.src=`https://maps.${c}apis.com/maps/api/js?`+e;d[q]=f;a.onerror=()=>h=n(Error(p+" could not load."));a.nonce=m.querySelector("script[nonce]")?.nonce||"";m.head.append(a)}));d[l]?console.warn(p+" only loads once. Ignoring:",g):d[l]=(f,...n)=>r.add(f)&&u().then(()=>d[l](f,...n))})({key:"YOUR_API_KEY",v:"weekly",// Use the 'v' parameter to indicate the version to use (weekly, beta, alpha, etc.).// Add other bootstrap parameters as needed, using camel case.});</script>
Tiếp theo, hãy sử dụng toán tử await để gọi importLibrary() từ bên trong hàm async, như sau:
// Import the Places Library for PlaceDetailsElement and PlaceSearchElementconst{PlaceDetailsElement,PlaceSearchElement}=awaitgoogle.maps.importLibrary('places');// Import the Elevation Library for ElevationElementconst{ElevationElement}=awaitgoogle.maps.importLibrary('elevation');
