篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了无法读取未定义的'角度误差'属性'panTo'相关的知识,希望对你有一定的参考价值。
我想在AGM地图上打开一个下拉菜单平移到某个城市。我这样做是通过在map组件中创建此方法,然后从View调用它:
public move = () => {
alert("Test");
const position = new google.maps.LatLng( 52.379189, 4.899431);
this.map.panTo(position);
}
但是,我收到此错误消息:
无法读取未定义的'panTo'属性
有人可以指出出了什么问题吗?
import {Component, OnInit} from "@angular/core";
import { GoogleMapsAPIWrapper } from '@agm/core';
import { MapsAPILoader } from '@agm/core';
import { Observable, Observer } from 'rxjs';
import {GMapsService} from "./map.service";
import * as data from './inkomen.json';
import * as inbraakdata from '../../assets/output.json';

this.result = inbraak_latlon;
}
ngOnInit(){
console.log(this.jsonData)
console.log(this.jsonLatlon.data)
console.log(this.results)
this.convert()
}
convert(){
for(var i = 0; i < this.jsonData.length; i++){
var spl = this.jsonData[i].wijk.split(" ");
// this.getLatLon(this.jsonData[i].wijk, this.jsonData[i].stad,
this.jsonData[i].inkomen)
}
//this.showArr()
}
title: string = 'My first AGM project';
lat: number = 52.1941679;
lng: number = 4.6820146;
public move= () => {
alert("test");
const position = new google.maps.LatLng(52.379189, 4.899431);
this.map.panTo(position);
}
}
答案
你的地图应该被初始化为方法.map,因为你已经在使用@agm/core
你可以使用GoogleMapsAPIWrapper
进口
import { AgmCoreModule, GoogleMapsAPIWrapper, AgmInfoWindow, AgmDataLayer, CircleManager, AgmCircle } from '@agm/core';
并参考
@ViewChild(GoogleMapsAPIWrapper) private gmapWrapper: GoogleMapsAPIWrapper;
你可以做到
this.gmapWrapper.panTo(position);
