How To Use Jquery In Angular

by

Angular is a popular framework for building responsive web applications, while jQuery is one of the most widely used JavaScript libraries to simplify DOM manipulation and event handling. In this blog post, we will discuss how to use jQuery in an Angular application.

Step 1: Install jQuery

First, you need to install jQuery in your project. You can do this using npm (Node Package Manager) by running the following command in your project directory:

<>
npm install jquery –save

Step 2: Import jQuery

After installing jQuery, you need to import it into your Angular application. To do this, open the angular.json file in your project and add the following line to the scripts array:

<>
“scripts”: [
“node_modules/jquery/dist/jquery.min.js”
]

This will ensure that the jQuery library is loaded before your Angular application starts.

Step 3: Use jQuery in Your Angular Components

Now that jQuery is installed and imported, you can use it in your Angular components. To do this, you need to declare the $ variable in your component. Add the following line at the top of your component file, after the import statements:

<>
declare var $: any;

This declares the $ variable as a global variable, allowing you to use it within your component. Now you can use jQuery just as you would in any other JavaScript project.

Example: Using jQuery in an Angular Component

Let’s say you want to use jQuery to hide an element with the ID myElement when a button is clicked. First, add the following HTML to your component’s template:

<>

This element will be hidden when the button is clicked.

Next, add the following code to your component’s TypeScript file:

<>
hideElement() {
$(‘#myElement’).hide();
}

This code defines a function called hideElement that uses jQuery to hide the element with the ID myElement. The function is called when the button is clicked, thanks to the Angular (click) event binding.

Conclusion

In this blog post, we learned how to install and import jQuery in an Angular application and use it in our Angular components. While Angular provides a powerful set of tools for DOM manipulation and event handling, jQuery can still be useful in certain situations. By following these steps, you can easily integrate jQuery into your Angular projects.
