angular2如何动态更改输入变量

Question

如果问题没有正确设置，对不起，我希望我能通过向你展示这个来让你明白我的意思：

<sebm-google-map-marker 
             *ngFor="let clustermarker of clusters" 
             (markerClick)="clustermarkerClicked()" 
             [latitude]="clustermarker.latitude" 
             [longitude]="clustermarker.longitude" 
             [iconUrl]="clustermarker.icon" 
             [visible]="true">
</sebm-google-map-marker>

如您所见，我在标记标签中有一个可见的输入，并且我的谷歌地图上有一个 zoomChange 事件，名为：

testFunction(e){
  console.log(e);

  if ( e === 17 || e === 18) {
   Here I want to set the variable of visible to false
 }
}

<sebm-google-map-marker 
             *ngFor="let clustermarker of clusters" 
             (markerClick)="clustermarkerClicked()" 
             [latitude]="clustermarker.latitude" 
             [longitude]="clustermarker.longitude" 
             [iconUrl]="clustermarker.icon" 
             [visible]="isVisible">
</sebm-google-map-marker>

isVisible:boolean = false;
testFunction(e){
  console.log(e);

  if ( e === 17 || e === 18) {
   this.isVisible = true;
 }
}
