ReactJS dangerouslySetInnerHTML Attribute
React.js library is all about splitting the app into several components. Each Component has its own lifecycle. React provides us some in-built methods that we can override at particular stages in the life-cycle of the component.
In class-based components, the dangerouslySetInnerHTML attribute is used to set innerHTML for the page. This is the replacement for innerHTML attribute.
Creating React Application And Installing Module:
-
Step 1: Create a React application using the following command.
npx create-react-app foldername
-
Step 2: After creating your project folder i.e. foldername, move to it using the following command.
cd foldername
Project Structure: It will look like the following.
Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.
App.js
import React from 'react'; // Defining our App Component const App = () => { // Function to demonstrate dangerouslySetInnerHTML attribute function Set() { return { __html: 'Setting HTML using dangerouslySetInnerHTML attribute' }; } // Returning our JSX code return <> <div> <h1>w3wiki</h1> <div dangerouslySetInnerHTML={Set()}></div> </div> </>; } // Exporting your Default App Component export default App |
Step to Run Application: Run the application using the following command from the root directory of the project:
npm start
Output: Now open your browser and go to http://localhost:3000/, you will see the following output:
