Issues encountered while attempting to update data in angular2-datatable

Once the datatable has been rendered, I am facing an issue where I cannot update the data. I'm utilizing angular2-datatable.

In my appcomponent.html file:

If I try to update 'data2' in my appcomponent.ts file as shown below:

this.httpservice.getdata().subscribe
(data=>
{   
    this.data2 = data;
    
    for (let i = 0; i < 21; i++) {
        markerarray[i] = new google.maps.Marker({
            position: new google.maps.LatLng(this.data2[i].latitude, this.data2
            [i].longitude),
            title: this.data2[i].name,
            map: map
        });
     }

    google.maps.event.addListener(map, 'idle', function () {

            var bounds = map.getBounds();
           
           for (var i = 0; i < 20; i++) {
                var marker = markerarray[i];
               
               if (bounds.contains(marker.getPosition()) === true) {
                    // This line doesn't work for me
                    this.data2.length = 0;
                }
            }
     });
})

I aim to clear the datatable once the markers are within the boundaries.

Answer №1

After much trial and error, I managed to come up with a workaround, although I’m not entirely convinced it’s the most effective method.

In order to detect changes, I resorted to using ChangeDetectorRef in my code.

constructor(private http: Http,private httpservice: HttpService,private ref: ChangeDetectorRef) {
       ref.detach();
    setInterval(() => {
      this.ref.detectChanges();
    },1000);
}
