你好吗?我正在学习带有Ionic 3教程的Google Maps。我已经完成了所有解释,但是当项目启动时,出现这个错误。我已经调查了很多,但没有任何工作。谢谢!。IONIC 3:Uncaught(承诺):ReferenceError:google没有定义ReferenceError
Error: Uncaught (in promise): ReferenceError: google is not defined
ReferenceError: google is not defined
这是我的代码:
home.ts
import { Component, ViewChild, ElementRef } from '@angular/core';
import { NavController } from 'ionic-angular';
import { IonicPage } from 'ionic-angular';
declare var google;
@IonicPage()
@Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
@ViewChild('map') mapElement:ElementRef;
map: any;
start = 'chicago, il';
end = 'chicago, il';
directionsService = new google.maps.DirectionsService;
directionsDisplay = new google.maps.DirectionsRenderer;
constructor(public navCtrl: NavController) {
}
ionViewLoad(){
this.initMap();
}
initMap(){
this.map = new google.maps.Map(this.mapElement.nativeElement,
{
zoom: 7,
center: {lat: 41.85, lng: -87.65}
});
this.directionsDisplay.setMap(this.map);
}
calculateAndDisplayRoute(){
this.directionsService.route({
origin: this.start,
destination: this.end,
travelMode: 'DRIVING',
}, (response, status) => {
if(status == 'OK'){
this.directionsDisplay.setDirections(response);
}else{
window.alert('Directions request failed due to ' +
status);
}
});
}
}
同样的问题是这样的一个插件科尔多瓦?你在设备上运行吗? –
号笔记本浏览器。是的,是一个科尔多瓦插件。 –
cordova插件没有加载'ionic serve'。使用模拟器/设备 –
