How to refresh Jquery Data-table after event performed in angular 6

How to refresh Jquery Data-table after event performed in angular 6

To refresh a jQuery DataTable after an event in Angular 6, you need to integrate jQuery DataTables with Angular. The process involves the following steps:

  1. Initialize the DataTable.
  2. Trigger the DataTable to refresh after the event.
  3. Ensure that Angular's change detection is aware of the updates.

Step-by-Step Guide

Step 1: Initialize the DataTable

First, initialize the DataTable in your component.

import { Component, OnInit, AfterViewInit } from '@angular/core'; declare var $: any; @Component({ selector: 'app-your-component', templateUrl: './your-component.component.html', styleUrls: ['./your-component.component.css'] }) export class YourComponent implements OnInit, AfterViewInit { constructor() { } ngOnInit(): void { } ngAfterViewInit(): void { this.initializeDataTable(); } initializeDataTable(): void { $(document).ready(function () { $('#example').DataTable(); }); } }

Step 2: Trigger DataTable Refresh

To refresh the DataTable after an event, you need to destroy and reinitialize it.

import { Component, OnInit, AfterViewInit } from '@angular/core'; declare var $: any; @Component({ selector: 'app-your-component', templateUrl: './your-component.component.html', styleUrls: ['./your-component.component.css'] }) export class YourComponent implements OnInit, AfterViewInit { constructor() { } ngOnInit(): void { } ngAfterViewInit(): void { this.initializeDataTable(); } initializeDataTable(): void { $(document).ready(function () { $('#example').DataTable(); }); } refreshDataTable(): void { $('#example').DataTable().destroy(); this.initializeDataTable(); } // Example event onSomeEvent(): void { // Perform your logic here this.refreshDataTable(); } }

Step 3: Ensure Angular's Change Detection

Make sure Angular is aware of changes and updates the view accordingly. You might need to use ChangeDetectorRef to manually trigger change detection.

import { Component, OnInit, AfterViewInit, ChangeDetectorRef } from '@angular/core'; declare var $: any; @Component({ selector: 'app-your-component', templateUrl: './your-component.component.html', styleUrls: ['./your-component.component.css'] }) export class YourComponent implements OnInit, AfterViewInit { constructor(private cdr: ChangeDetectorRef) { } ngOnInit(): void { } ngAfterViewInit(): void { this.initializeDataTable(); } initializeDataTable(): void { $(document).ready(function () { $('#example').DataTable(); }); } refreshDataTable(): void { $('#example').DataTable().destroy(); this.initializeDataTable(); this.cdr.detectChanges(); // Ensure Angular is aware of the change } // Example event onSomeEvent(): void { // Perform your logic here this.refreshDataTable(); } }

HTML Template

Ensure your HTML template includes the DataTable structure:

<table id="example" class="display" style="width:100%"> <thead> <tr> <th>Name</th> <th>Position</th> <th>Office</th> <th>Age</th> <th>Start date</th> <th>Salary</th> </tr> </thead> <tbody> <tr> <td>Tiger Nixon</td> <td>System Architect</td> <td>Edinburgh</td> <td>61</td> <td>2011/04/25</td> <td>$320,800</td> </tr> <!-- More rows here --> </tbody> </table>

Summary

  1. Initialize the DataTable: Set up the DataTable when the component initializes.
  2. Trigger Refresh: Destroy and reinitialize the DataTable when an event occurs.
  3. Ensure Change Detection: Use Angular's change detection to ensure the view is updated.

By following these steps, you can efficiently refresh a jQuery DataTable after an event in an Angular 6 application.
