Using full featured Datatables Plugin with Angular 6

Question

I am trying to add Datatables plugin (datatables.net) facility with my angualar 6 project. I am not sure how should I include the necessary css, js and other required files

Answer 1

Get JSON data from API url

Now you have to play in two components only one is html & other is .ts file

sample.Component.html

<table  id="_zonetable" class="row-border hover" datatable [dtOptions]="dtOptions" [dtTrigger]="dtTrigger">
   <thead>
   ---
   </thead>
    <tbody>
    <tr  *ngFor="let item of ArrayResponse ; let i=index">
      </tr>
    </tbody>
 </table>

now come to .ts file like sample.Component.ts

import { Component, OnInit ,OnDestroy} from '@angular/core';
import { Subject } from 'rxjs';
import { DataTableDirective } from 'angular-datatables';
declare var $: any;

now in the export :

export class UtilityComponent implements OnDestroy, OnInit {
dtElement: DataTableDirective;
dtOptions: DataTables.Settings = {};
dtTrigger: Subject<any> = new Subject();



 ngOnInit(): void {
   this.dtOptions = {
      pagingType: 'full_numbers',
      pageLength: 10
    };


ngOnDestroy(): void {
    // Do not forget to unsubscribe the event
    this.dtTrigger.unsubscribe();

   if ($.fn.DataTable.isDataTable( '#_zonetable' )) {
    //   // call the loader
      $('#_zonetable').dataTable().api().destroy();
    }
  }

  rerender(): void {
    this.dtElement.dtInstance.then((dtInstance: DataTables.Api) => {
      // Destroy the table first
      dtInstance.destroy();
      // Call the dtTrigger to rerender again
      // this.dtTrigger.next();
    });
  }

ServiceFunction() {
    this.ArrayResponse=[];
    if ($.fn.DataTable.isDataTable( '#_zonetable' )) {
      //   // call the loader
        $('#_zonetable').dataTable().api().destroy();
      }


this.availservice.JsonAPi()
  .subscribe((json) => {

    this.ArrayResponse = json; //here you will get JSON response
     // Calling the DT trigger to manually render the table
    // debugger;

    if ($.fn.DataTable.isDataTable( '#_zonetable')) {
    //   // call the loader
      $('#_zonetable').dataTable().api().destroy();
        }
        this.dtTrigger.next();
        console.log(this.ArrayResponse);
        setTimeout(() => {
          $('.overlaysv').hide();              
        }, 2000);

      });
  }

Answer 2

I got DataTables working by doing the following:

angular.json

     "styles": [
          "src/styles.css",
          "node_modules/bootstrap/dist/css/bootstrap.min.css",
          "node_modules/datatables.net-dt/css/jquery.dataTables.css"
        ],
        "scripts": [
          "node_modules/jquery/dist/jquery.js",
          "node_modules/datatables.net/js/jquery.dataTables.js"
        ]

app.module.ts

        import {DataTablesModule} from 'angular-datatables';


        imports: [
                 ...
                 DataTablesModule
                ]

You may have to stop and re-serve to see changes.
