How To Jquery In React Js

by

React JS is a popular, versatile library for building user interfaces, and jQuery is a widely used, feature-rich and lightweight JavaScript library. While React is generally preferred for modern web applications, you may still encounter situations where you need to incorporate jQuery into a React project.

In this blog post, we will explore how to use jQuery in a React JS project, by covering the following topics:

  • Installing and importing jQuery
  • Using jQuery with React lifecycle methods
  • Examples of using jQuery in React
  • Considerations when using jQuery with React

Installing and Importing jQuery

To get started, you will need to install the jQuery library in your React project. You can do this using npm or yarn:

Using npm:

npm install jquery –save

Using yarn:

yarn add jquery

After installing jQuery, you will need to import it in your React component file:

import $ from “jquery”;

Using jQuery with React Lifecycle Methods

To use jQuery in your React component, it is essential to use React lifecycle methods, such as componentDidMount and componentWillUnmount, to manage the jQuery code execution.

The componentDidMount method is called after the component has been rendered to the DOM. You can use this method to execute jQuery code that manipulates the DOM or adds event listeners.

Similarly, if your jQuery code creates event listeners or other resources, you should use the componentWillUnmount method to clean up and remove these resources before the component is unmounted and destroyed.

Examples of using jQuery in React

Here are a few examples of how to use jQuery in a React component:

Example 1: Using jQuery to Show/Hide Elements

In this example, we have a simple React component that contains a button and a hidden div. When the button is clicked, the hidden div is toggled.

First, create a new React component and import the required libraries: 

        import React, { Component } from "react";
        import $ from "jquery";

        class App extends Component {
            // ...
        }

        export default App;

Next, add the componentDidMount and componentWillUnmount lifecycle methods to the component: 

        class App extends Component {
            componentDidMount() {
                // Add event listeners using jQuery
            }

            componentWillUnmount() {
                // Remove event listeners using jQuery
            }

            // ...
        }

Now, add the button and hidden div elements to the render method: 

        class App extends Component {
            // ...

            render() {
                return (
                    </p><div classname="App">
                        <button id="toggle-btn">Toggle hidden div</button>
                        <div id="hidden-div" style="{{" display:>
                            This div is hidden!
                        </div>
                    </div>
                );
            }
        }

Finally, add the jQuery code to the componentDidMount method to toggle the hidden div when the button is clicked: 

        class App extends Component {
            componentDidMount() {
                // Add event listeners using jQuery
                $("#toggle-btn").on("click", () =&gt; $("#hidden-div").toggle());
            }

            componentWillUnmount() {
                // Remove event listeners using jQuery
                $("#toggle-btn").off("click");
            }

            // ...
        }

Considerations when using jQuery with React

While using jQuery in your React project might be necessary in some cases, it is essential to remember that using jQuery alongside React can lead to some issues and challenges. React encourages the use of a declarative programming style and a one-way data flow, which can conflict with jQuery’s imperative programming style.

When possible, it is a good idea to stick with React’s built-in features and libraries to manage the DOM and handle events. However, if you must use jQuery, make sure to implement it cautiously and use React lifecycle methods to manage jQuery’s effects on the DOM.

Happy coding!
