Question

我正在尝试在编辑和拖动多边形时获取更新的多边形路径。我尝试像下面的代码那样做。

在我的打字稿中：

 @ViewChild(AgmPolygon) polygon: any;
 this.polygon.getPaths().then((x: any[]) => {
   x.forEach(y => {
     console.log('-');
     y.forEach(z => console.log(z.lat(), z.lng()));
   });
 });

我也按照以下链接1st link 2nd link。

在我的HTML中：

<agm-map [latitude]="lat" [fullscreenControl]="true" 
    (mapClick)="mapClicked($event)" [longitude]="lng" [zoom]="8" [mapTypeControl]="true">

  <agm-polygon [fillColor]="item.fillColor" (polyMouseOut)="polyMouseOut($event)" 
    (polyMouseMove)="polyMouseMove($event)" [fillOpacity]="item.fillOpacity" 
    *ngFor="let item of zonesPath; let i=index" [editable]="item.ZoneID==ZoneID" 
    (polyMouseUp)="polyMouseUp(item,$event)" (polyMouseDown)="polyMouseDown($event)" 
    (polyDblClick)="polyDblClick($event)" (polyDragStart)="polyDragStart($event)" 
    (polyDragEnd)="polyDragEnd($event,item)" (polyDrag)="polyDrag($event)" 
    [polyDraggable]="false" [paths]="item.ZonePaths" (polyClick)="polyclick($event)">
  </agm-polygon>

  <agm-polygon [paths]="paths"></agm-polygon>
</agm-map>

我正在做* ngFor for polygon.and我的json数据是：

{
"ZoneID": "594dff0ee10452d8567b23c6",
"strokeColor" : "#038063",
"strokeOpacity" : 0.2,
"strokeWeight" : 2,
"fillColor" : "#038063",
"fillOpacity" : 0.35,
"draggable" : false,
"editable" : false,
"visible" : true,
"ZonePaths": [ 
    {
        "lat" : 17.535107299215,
        "lng" : 78.2346725463869
    }, 
    {
        "lat" : 17.541981926489,
        "lng" : 78.240509033203
    }, 
    {
        "lat" : 17.54460076354,
        "lng" : 78.249778747559
    }, 
    {
        "lat" : 17.55082034986,
        "lng" : 78.284454345703
    }]}

我必须在阅读ATM agm多边形编辑更改事件后才能克服这个问题，它仍然在PR上。

所以，我回到基础并寻找谷歌地图api类v3。

@ViewChild(AgmMap) map: any;
polygon: any;
this.map._mapsWrapper.createPolygon({
      paths: this.area,
      strokeColor: '#FF0000',
      strokeOpacity: 0.8,
      strokeWeight: 2,
      fillColor: '#FF0000',
      fillOpacity: 0.3,
      editable: true,
    }).then((polygon: any) => {
      this.polygon = polygon
    });

在此之后，您可以使用getPath（）

添加事件或获取路径更改

console.debug(this.polygon.getPath())

如何在编辑和拖动时获取agm多边形的路径？
