How To Jquery In Angular

Angular is a powerful framework that is used to build robust and scalable web applications. While Angular has its own set of tools and libraries, sometimes you may need to use third-party libraries like jQuery to perform some specific tasks. But, integrating jQuery into Angular can be a bit tricky. In this tutorial, we’ll show you how to use jQuery in an Angular application.

Step 1: Install jQuery

To use jQuery in your Angular project, you first need to install it. You can do this using npm (Node Package Manager). Simply run the following command in your project’s root directory:

npm install jquery –save

This command will install jQuery and save it as a dependency in your project’s package.json file.

Step 2: Include jQuery in Angular Project

After installing jQuery, you need to include it in your Angular project. To do this, open the angular.json file and add the path to the jQuery file in the “scripts” array. Here’s an example:

{
    "projects": {
        "my-app": {
            ...
            "architect": {
                "build": {
                    ...
                    "options": {
                        ...
                        "scripts": [
                            "node_modules/jquery/dist/jquery.min.js"
                        ],
                        ...
                    }
                }
            }
        }
    }
}
    

Save the changes and restart your development server if it’s already running.

Step 3: Use jQuery in Your Angular Component

Now that jQuery is installed and included in your project, you can use it in your Angular components. To do this, first, import the jQuery library at the top of your component’s TypeScript file like this:

import * as $ from ‘jquery’;

After importing jQuery, you can use it in your component just like you would in a regular JavaScript file. Here’s an example of how you can use jQuery to toggle a div’s visibility on button click:

import { Component } from '@angular/core';
import * as $ from 'jquery';

@Component({
    selector: 'app-root',
    template: `
        <button>Toggle Div</button>
        <div id="myDiv" style="display: none;">Hello, world!</div>
    `,
})
export class AppComponent {
    toggleDiv() {
        $('#myDiv').toggle();
    }
}
    

In this example, we imported jQuery and used it to toggle the visibility of a div with the ID “myDiv” when the button is clicked. The toggleDiv() function is called when the button is clicked, and it uses jQuery’s toggle() method to show or hide the div.

Conclusion

Using jQuery in an Angular application can be a powerful way to perform specific tasks that may not be easily achievable using Angular’s built-in tools and libraries. By following these steps, you can easily integrate jQuery into your Angular project and use it as needed. However, it is important to note that using jQuery in Angular should be done with caution, as it can sometimes lead to issues with Angular’s change detection, performance, and other aspects of your application.
