angular2如何更改動態

Question

輸入變量如果問題是不正確設置與正確的字遺憾的是，我希望我能讓你清楚我的意思是你展示這一點：

<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> 

正如你看到我在標識器標籤可見的輸入，我有我的谷歌地圖上的zoomChange事件命名爲：

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; 
} 
}
