angular - 在 <agm-direction> 中拖动原点时方向发生变化时获取坐标

Question

当原点标记在 map 上拖动时，我试图检索纬度和经度等坐标。

我尝试实现 Dragend 或 Dragend 属性，但没有任何效果

html

<agm-map id="map" [latitude]='origin.lat' [longitude]='origin.lng' [zoom]='zoom'>
<agm-direction [origin]="origin" [destination]="destination" [renderOptions]="renderOptions" [markerOptions]="markerOptions" (dragEnded)="getcoords($event)"></agm-direction>
</agm-map>

ts 文件

import { Component } from '@angular/core';
import { Geolocation } from '@ionic-native/geolocation/ngx';
import { ViewChild, ElementRef, NgZone } from '@angular/core';
import { MapsAPILoader, AgmMap } from '@agm/core';
import {} from "googlemaps";
declare let google: any;
@Component({
  selector: 'app-root',
  templateUrl: './direction.component.html',
  styleUrls: ['./app.component.css'],
})

export class AppDirection
{
public origin: {};
public destination: {};
public renderOptions = {
   suppressMarkers: true,
}

public markerOptions = {
   origin: {
           draggable: true,
        },
   destination: {
            opacity: 0.8,
        },
 }

 origin={lat:30.7227148,lng:76.6932551};
 destination={lat:30.7123702,lng:76.71970320000003};   

 constructor(private mapsAPILoader: MapsAPILoader, private ngZone: NgZone){}

 ngOnInit() {}

 getcoords(event){
  console.log(event);
 }  
}

originDrag 是检索 <agm-direction> 中原点变化时的纬度和经度的函数下面是对我有用的代码:

html 代码:

<agm-direction [origin]="origin" [destination]="destination" [renderOptions]="renderOptions" [markerOptions]="markerOptions" (originDrag)="getcoords('direction',$event)"> </agm-direction>

在 ts 文件中:

getcoords(type,event)
    {
        let coords=JSON.stringify(event);
        let coords3=JSON.parse(coords);
        console.log("updated latitude :: "+coords3.lat);
        console.log("updated longitude :: "+coords3.lng);
    }
