[Fixed] angular 7 – reload data in data table

Issue

I’m using angular 7 with angular-datatables.
I’m tring to define a “rerender” button in order to reload data like in this example.

I don’t understand what should I place in the render function:

My API function:

fn_getFavoriteTables() {

  this._getFavoriteTablesApiCall =  this.getFavoriteTablesService.getFavoriteTables(Number(localStorage.getItem('UserID')), Number(localStorage.getItem('BranchID'))).pipe(takeUntil(this.destroySubject$)).subscribe(x => {
        this.getFavoriteTables = x;
        this.dtTrigger.next();
    });

};

rerender function:

rerender(): void {
    this.dtElement.dtInstance.then((dtInstance: DataTables.Api) => {
        // Destroy the table first 

        dtInstance.destroy();


        // Call the dtTrigger to rerender again
        this.dtTrigger.next();
    });
}

ngOnDestroy(): void {
  console.log('ngDestroy');
  // Do not forget to unsubscribe the event
  this.dtTrigger.unsubscribe();
}

Solution

Found an answer that worked for me:
this is the source site

 rerender(): void {
    this.dtElement.dtInstance.then((dtInstance: DataTables.Api) => {
        // Destroy the table first 
        //debugger;
        var table = $('#favoriteTable').DataTable();

        $('#tableDestroy').on('click', function () {
            table.destroy();
        });

        dtInstance.destroy();

        this.fn_getFavoriteTables();

    });
}
