如何解决Google API Places-Searchbox Angle 8
我找到了一个链接,用于运行在 JsFiddle 上进行搜索的地方,但是我不知道如何在我的代码中进行操作。这是我在下面关注的链接。
https://developers.google.com/maps/documentation/javascript/examples/places-searchbox#maps_places_searchbox-typescript
正如我在 JsFiddle 中看到的代码一样,它可以正常工作,但是当我在下面的 Angular 8 中传输代码时。
这是我的 TestPage4.ts
import { Component,OnInit } from '@angular/core';
import { google } from '@agm/core/services/google-maps-types';
@Component({
selector: 'TestPage4',templateUrl: './TestPage4.html',styleUrls: ['./TestPage4.css']
})
export class TestPage4 implements OnInit {
constructor() {
}
ngOnInit() {
//this.initAutocomplete();
//throw new Error("Method not implemented.");
}initAutocomplete() {
const map = new google.maps.Map(document.getElementById("map"),{
center: {
lat: -33.8688,lng: 151.2195
},zoom: 13,mapTypeId: "roadmap"
}); // Create the search box and link it to the UI element.
const input = document.getElementById("pac-input");
const searchBox = new google.maps.places.SearchBox(input);
map.controls[google.maps.ControlPosition.TOP_LEFT].push(input); // Bias the SearchBox results towards current map's viewport.
map.addListener("bounds_changed",() => {
searchBox.setBounds(map.getBounds());
});
let markers = []; // Listen for the event fired when the user selects a prediction and retrieve
// more details for that place.
searchBox.addListener("places_changed",() => {
const places = searchBox.getPlaces();
if (places.length == 0) {
return;
} // Clear out the old markers.
markers.forEach(marker => {
marker.setMap(null);
});
markers = []; // For each place,get the icon,name and location.
const bounds = new google.maps.LatLngBounds();
places.forEach(place => {
if (!place.geometry) {
console.log("Returned place contains no geometry");
return;
}
const icon = {
url: place.icon,size: new google.maps.Size(71,71),origin: new google.maps.Point(0,0),anchor: new google.maps.Point(17,34),scaledSize: new google.maps.Size(25,25)
}; // Create a marker for each place.
markers.push(
new google.maps.Marker({
map,icon,title: place.name,position: place.geometry.location
})
);
if (place.geometry.viewport) {
// Only geocodes have viewport.
bounds.union(place.geometry.viewport);
} else {
bounds.extend(place.geometry.location);
}
});
map.fitBounds(bounds);
});
}
}
这是我的 TestPage4.html
<div class="row m-t-15" style="background:#FFF;">
<div class="col-12 n_m_p panel panel-inverse" data-sortable-id="table-basic-7" style="margin:0; padding:0;">
<!DOCTYPE html>
<html>
<head>
<title>Places Search Box</title>
<script src="https://polyfill.io/v3/polyfill.min.js?features=default"></script>
<script
src="https://maps.googleapis.com/maps/api/js?key=MY_API_KEY&callback=initAutocomplete&libraries=places&v=weekly"
defer
></script>
<!-- jsFiddle will insert css and js -->
</head>
<body>
<input id="pac-input" class="controls" type="text" placeholder="Search Box" />
<div id="map"></div>
</body>
</html>
</div>
</div>
现在,如果我尝试添加
ngOnInit() {
this.initAutocomplete();
}
它给了我这样的错误 ERROR TypeError:无法读取未定义的属性“地图” 。这是下面的屏幕截图。
我不明白如何使此代码在搜索地图上的位置时起作用。?
