Question

在角度6中，我正在为agm-polyline使用流动代码。我想在agm-polyline中添加箭头符号（折线）（https://developers.google.com/maps/documentation/javascript/examples/overlay-symbol-arrow）。但是编译器显示错误，例如不能绑定到“ icon”，因为它不是“ agm-polyline”的已知属性。...

<agm-polyline [strokeColor]="color" [icon]="icon"  >
          <agm-polyline-point  *ngFor="let marker of markers ; let i=index"  [latitude]="marker.lat" [longitude]="marker.lng">
          </agm-polyline-point>

        </agm-polyline>

对于agm-polyline箭头符号（折线），我该怎么办？

Answer 1

agm使用[iconUrl]而不是[icon]。尝试这样做，然后在.ts文件中设置网址，如下所示：


  public icon = {
    url: 'http://earth.google.com/images/kml-icons/track-directional/track-4.png',
    scaledSize: {
      width: 30,
      height: 30
    }
}

<agm-polyline [strokeColor]="'red'" [strokeWeight]="'1.5'">
                                        <agm-icon-sequence [fixedRotation]="false"
                                            [repeat]= "'50px'"
                                            [offset]="100" 
                                            [path]="'FORWARD_OPEN_ARROW'">
                                        </agm-icon-sequence>
                                        <agm-polyline-point *ngFor="let line of circles_path" 
                                        [latitude]="line.lat"
                                        [longitude]="line.long" >
                                        </agm-polyline-point>
                                    </agm-polyline>
