Mouse hover in React

The onMouseEnter sets the isShown variable to true, and the onMouseLeave sets it back to false. We process a div element below the button using the isShown variable. If it's true, then the div enters the DOM and shows the details, and If it's false, it's removed from the DOM. onMouseEnter and onMouseLeave are activated when the mouse enters and leaves the image. Also, hover will only work if we use the correct CSS format.  


A React component that tells its children of hover interactions. And also observe mouseenter, mouseleave, mouseover, and mouseout events. Note that if you do not get the right specificity, the hover style will not work.  


We want to detect the following states for an HTML element when hovering over an element:  

  • Beginning to hover over an element 
  • Leaving a hovered element 

For detecting the hover state for an element, React has provided the following event handlers: 

  • onMouseEnter 
  • onMouseLeave 


react-hover-observer 

ReactHoverObserver receives a Boolean prop named isHovering for each child component. The react-hover-observer wraps its children in a div, which is the condition for triggering hover events. Optionally implement the function as a child component pattern. This is especially useful if your component has an interface with react-hover-observer. 


immutability-helper 

Note that this method has nothing to do with React. However, since this module is most commonly used in React. Without changing the source, we can mutate a copy of the data. 


Here is an example of how to do a mouse hover in Reactjs:

class App extends Component {

  render() {
    return (
      <div>
      {
        data.map(product =>
          <Product product={product} />
        )
      }

import React from 'react'
import ReactHoverObserver from 'react-hover-observer';

export default class Product extends React.Component {
  render() {
    const { product } = this.props
    return (
      <ReactHoverObserver className="product-grid-view col-6 col-md-4">
      {
        ({isHovering}) => (

                </div>
              }
            </div>
            <div className="details-holder">
              <span className="part-text">{product.desc}</span><br />
              <span className="manufacturer-text">{product.manufacturer.name}</span>
              <div className="product-review_slide">
                <span className="product-review">0 review</span>
              </div>
              <span className="product-price">{product.salesPrice.toFixed(2)}</span>
              <span className="product-currency">Currency</span>
            </div>
          </div>
        )
      }
      </ReactHoverObserver>
    )
  }
}

Instructions

Follow the steps carefully to get the output easily.

  1. Install Node.js and React on your IDE(preferably Visual Studio Code).
  2. Create React Application using npx create-react-app foldername.
  3. cd foldername.
  4. npm i react-hover-observer
  5. npm i immutability-helper
  6. Open the folder in IDE.
  7. Copy the code using the "copy" button above and paste the index code(line no 1 to 14) into index.js and create a product file and paste the product code(line no 15 to 50) in to product.js file(remove the earlier code from index.js and refer DEMO for additional files).
  8. We have to create data.js file. Here, the content of the data is assigned.
  9. Import React component,render from React DOM,data from the data file, and product from product file.
  10. Open the terminal from IDE.
  11. npm start to run the file.


You can also refer this url DEMO for getting the above output.

I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.


I found this code snippet by searching for Mouse hover in React in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in VS Code 1.73.1 version.
  2. The solution is tested on Nodejs 16.14.2 version.
  3. react 18.2.0 version.
  4. react-hover-observer: 2.1.1
  5. immutability-helper: 3.1.1


Using this solution, we are able to do mouse hover in React with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to do mouse hover in React.
