[英]How to implement the Google map API search autocomplete in React
我正在遵循谷歌地图的官方指南,并尝试按照以下方式在我的反应应用程序中实现它:
import React, { Component } from 'react';
import './styles/locationInput.css';
export class locationInput extends Component {
render() {
const { values, handleChange } = this.props;
function initAutocomplete() {
var input = document.getElementById('pac-input');
var searchBox = new google.maps.places.SearchBox(input);
var markers = [];
searchBox.addListener('places_changed', function() {
var places = searchBox.getPlaces();
if (places.length == 0) {
return;
}
markers.forEach(function(marker) {
marker.setMap(null);
});
markers = [];
var bounds = new google.maps.LatLngBounds();
places.forEach(function(place) {
if (!place.geometry) {
console.log("Returned place contains no geometry");
return;
}
var 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)
};
markers.push(new google.maps.Marker({
icon: icon,
title: place.name,
position: place.geometry.location
}));
if (place.geometry.viewport) {
bounds.union(place.geometry.viewport);
} else {
bounds.extend(place.geometry.location);
}
});
});
}
initAutocomplete()
return (
<input
defaultValue={values.CollegeName}
onChange={handleChange('CollegeName')}
id="pac-input"
className="controls"
type="text"
placeholder="Search Box"
/>
);
}
}
export default locationInput;
我在
index.html
中初始化了<script>
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places&callback=initAutocomplete"
async defer></script>
但我收到了这个错误
编译失败
./src/public/form/lib-component/locationInput.js

我的问题是,当我尝试在普通的html
和javascript
中实现此代码时,它完美地工作但没有反应,所以我怎样才能让它在这里工作,我如何指定google
在这里的含义?
在您的代码中用new window.google.maps
替换new google.maps
。
