Solved - Angular 11 Datatable | Dynamic Data | No Data Available in Table

Hello friends, welcome back to my blog. Today in this blog post, I am going to show you, Solved – Angular 11 Datatable | Dynamic Data | No Data Available in Table.

Angular 11 Datatable

Guys, the main purpose of making this post that, the most of my blog and my YouTube channel viewers have issue related to Angular Datatable with Dynamic Data and issue is “No Data Available in Table” but now in this post, I am sharing the few lines of code and with that Angular Datatable dynamic data “No Data Available in Table” will be gone.


Angular 11 came and if you are new then you must check below link:

  1. Angular11 Basic Tutorials

Friends now I proceed onwards and here is the working code snippet for Solved – Angular 11 Datatable | Dynamic Data | No Data Available in Table and please use carefully this to avoid the mistakes:

1. Firstly friends we need fresh angular 11 setup and for this we need to run below commands but if you already have angular 11 setup then you can avoid below commands. Secondly we should also have latest node version installed on our system:

npm install -g @angular/cli 

ng new angulardatatable //Create new Angular Project

cd angulardatatable // Go inside the Angular Project Folder

ng serve --open // Run and Open the Angular Project

http://localhost:4200/ // Working Angular Project Url

 

2. Now friends, here we need to run below commands into our project terminal to install datatable modules, bootstrap(for good looks), jquery  modules into our angular application:

npm install jquery --save

npm install datatables.net --save

npm install datatables.net-dt --save

npm install angular-datatables --save

npm install @types/jquery --save-dev

npm install @types/datatables.net --save-dev

npm install bootstrap --save

 

3. After done with commands add below code into you angular.json file:

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

 

4. Now friends, we need to run below commands to create service file and run our angular project:

ng g service crud

ng serve --o

5. Now friends we just need to add below code into src/app/app.module.ts file:

...

import { HttpClientModule } from '@angular/common/http';
...
imports: [
...

HttpClientModule
]

 

6. Now friends we just need to add below code into src/app/crud.service.ts file:

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
@Injectable({
  providedIn: 'root'
})
export class CrudService {

  constructor(private http:HttpClient) { }
  public getusers()
    {
        //API request to php file
        return this.http.get('http://localhost/users.php');
    }
}

 

7. Now friends we just need to add below code into src/app/app.component.ts file:

...

import { CrudService } from './crud.service'; 
declare let $: any;

export class AppComponent  {
  data = [];
  dtOptions: any = {};
  constructor(private crudservice: CrudService) {}

  ngOnInit() {
  
  
    this.crudservice.getusers().subscribe((ret: any[])=>{
        
          this.data = ret;
         
          setTimeout(()=>{                          
            $('#datatableexample').DataTable( {
              pagingType: 'full_numbers',
              pageLength: 5,
              processing: true,
              lengthMenu : [5, 10, 25],
              order:[[1,"desc"]]
          } );
          }, 1);
          
          
      });
      
    
     
      
    }
}

 

8. Now friends we just need to add below code into src/app/app.component.html file to see the output on browser:

<table class="table table-hover table-bordered" id="datatableexample">
    <thead>
      <tr>
        <th>ID</th>
        <th>Email</th>
        <th>Username</th>
        
      </tr>
    </thead>
    <tbody>
   
       
          <tr *ngFor="let group of data">
            <td>{{group.id}}</td>
            <td>{{group.email}}</td>
            <td>{{group.username}}</td>
   
           
          </tr>
       
     
     
      
    </tbody>
  </table>

 

9. Now friends here is my php code snippet to fetch data and show  into angular 11  and I added this code into my xampp/htdocs/users.php file:

//Please create users database inside phpmysql admin and create userdetails tabel and create id, email and username fields

<?php
//Please create users database inside phpmysql admin and create userdetails tabel and create id, email and username fields

$servername = "localhost";
$username   = "root";
$password   = "";
$dbname     = "users";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 
    //get all users details
    $trp = mysqli_query($conn, "SELECT * from userdetails");
    $rows = array();
    while($r = mysqli_fetch_assoc($trp)) {
        $rows[] = $r;
    }
    print json_encode($rows);

?>

 

Now we are done friends. If you have any kind of query or suggestion or any requirement then feel free to comment below.

Note: Friends, I just tell the basic setup and things, you can change the code according to your requirements. For better understanding must watch video above.

I will appreciate that if you will tell your views for this post. Nothing matters if your views will be good or bad.

Jassa

    import { Component,OnInit } from ‘@angular/core’;
    import { Router } from “@angular/router”;
    import { AuthService } from ‘../../../services/auth.service’;

    @Component({
    selector: ‘app-totaljoining’,
    templateUrl: ‘./totaljoining.component.html’,
    styleUrls: [‘./totaljoining.component.css’]
    })
    export class TotaljoiningComponent implements OnInit {
    data: [];
    res: [];
    dtOptions: DataTables.Settings = {};

    constructor( public router: Router , private authService : AuthService) { }

    ngOnInit(): void {
    this.authService.getverifiedusers().subscribe(
    res => {
    this.data = res[‘data’];
    });

    this.dtOptions = {
