How To Jquery Function

jQuery is a popular JavaScript library that simplifies the process of creating dynamic web applications. It provides us with an easy-to-use, concise syntax for manipulating Document Object Model (DOM) elements, handling events, creating animations, and performing AJAX requests. In this blog post, we’ll learn how to create and use jQuery functions.

Step 1: Include the jQuery Library

Before you can start using jQuery functions, you need to include the jQuery library in your HTML file. You can download the library from the official jQuery website or use a Content Delivery Network (CDN) like Google or Microsoft. To include the library, add the following script tag to the head section of your HTML file:

<script src=""></script>

Step 2: Create a jQuery Function

Let’s create a simple jQuery function that hides an element when it is clicked. To do this, we’ll use the $(element).click(function) syntax, where element refers to the DOM element we want to manipulate, and function represents the action we want to perform.


This code snippet does the following:

  • Waits for the DOM to be fully loaded using the $(document).ready() function.
  • Attaches a click event handler to all button elements using the $(“button”).click() function. The $(“button”) selector targets all buttons on the webpage.
  • Uses the $(this).hide() function to hide the clicked button. The $(this) keyword refers to the currently clicked button.

Step 3: Combine with HTML and CSS

Now let’s combine our jQuery function with some simple HTML and CSS to see it in action:

<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
        button {
            font-size: 20px;
            padding: 10px;
    <script src=""></script>
    <button>Click me to hide!</button>

When you click the “Click me to hide!” button in this example, it will disappear, demonstrating our jQuery function in action. Feel free to experiment with other jQuery functions and elements to create more complex interactions.


In this blog post, we learned how to create a simple jQuery function that hides an element when it is clicked. By including the jQuery library, creating a function, and combining it with HTML and CSS, you can easily add dynamic interactivity to your web applications. Happy coding!
