How to catch an click event on pagination buttons next/previous of the DataTables Angular 5

How to catch click event in pagination buttons previous/next in angular 5. unfortunately I got the code in jquery.

jquery code:

var table = $('#example').DataTable({
 drawCallback: function(){
  $('.paginate_button.next', this.api().table().container())          
  .on('click', function(){
  alert('next');
 });       
 }
});

#stack overflow link

#jsFiddle link

But I need angular data table. If you have an example, how to catch the previous/next click event.

Button Row Click event

 buttonInRowClick(event: any): void {
    event.stopPropagation();
    console.log('Button in the row clicked.');
  }

Whole Row Click Event

wholeRowClick(): void {
    console.log('Whole row clicked.');
  }

Expecting next/previous button click event

nextButtonClickEvent():void {
   //do next particular records like  101 - 200 rows.
   //we are calling to api
}
previousButtonClickEvent():void {
  //do previous particular the records like  0 - 100 rows.
   //we are calling to API
}

Because I have thousands of records in my backend.

You need to provide a reference to your Angular component about the element that you are going to bind the functionality

<div #mytable></div>

In your component add an element reference with ViewChild

@ViewChild('mytable') tableRef: ElementRef;

Then use that element reference to bind the functionality that you want and make it accessible in angular

ngAfterViewInit(): void {
  this.table = $(this.tableRef.nativeElement).DataTable({
      drawCallback: function () {
        $('.paginate_button.next', this.api().table().container()).on('click', () =>  {
          // your angular method here
          this.nextButtonClickEvent();
        });
      }
  });
}

Just test your scope. By using arrow functions you can access the methods written in you class and that should do the trick

You can use any jquery code inside you component and use arrow function to maintain reference to this

component

declare let $: any;
@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {


  ngOnInit() {
    let table = $('#example').DataTable({
      drawCallback: () => {
        $('.paginate_button.next')
          .on('click', () => {
            this.nextButtonClickEvent();
          });
      }
    });
  }

  nextButtonClickEvent(): void {
       console.log('next clicked');
  }

}

The solution is to use event delegation by providing selector for target element as a second argument in on() call, see example below. According to jQuery on() documentation

I recommend using ngx-datatable library, very complete and easy to use ! Even the documentation is good ! https://github.com/swimlane/ngx-datatable
