To display the user information after clicking submit button in React, we need to call a function to trigger the window in React. If we need to show the user information in our render, we can use a state to manage that.


There are two components: the Function component and the Class component. React Components are independent and reusable bits of code, serving the same purpose as JavaScript functions, but work in isolation and return HTML. We use React components to build interactive user interfaces and web applications efficiently with significantly fewer codes than we would with vanilla JavaScript. It allows developers and users to easily create fast user interfaces for websites and applications. handleSubmit is used for easily submitting forms asynchronously with it, and its disabled inputs will appear as undefined values in form values. If we want to prevent users from updating an input from the user and wish to retain the form value, we can use readOnly or disable the entire <fieldset/>. In HTML, we can achieve this by displaying the DataGrid inside the form "submit" event and preventing the default submit action using the "preventDefault" method.


Here is an example of how you can display user info after clicking submit button in React:

import React, { Component } from 'react';

class Input extends Component {
  state = {
    firstName: '',
    showName: false

  }

  displayNameHandler = (e) => {
    let updatedName = e.target.value;
    this.setState({ firstName: updatedName });
    //console.log(updatedName);  
  }

  handleSubmit = (e) => {
    e.preventDefault();
    this.setState({
      showName: true
    });
  }

  render() {
    return (
      <div>
        <form onSubmit={this.handleSubmit}>
          <label>Enter the Name</label>
          <input type="text" name="firstName" onChange={this.displayNameHandler} value={this.state.firstName} />
          <button type="submit" onClick={this.handleSubmit}>Submit</button>
          {this.state.showName && <p>"FirstName: " {this.state.firstName}</p>}
        </form>
      </div>
    );
  }
}
export default Input;

Instructions

Follow the steps carefully to get the output easily.

  1. Install the Node.js and React on your IDE(preferable Visual Studio Code).
  2. Create React Application using npx create-react-app foldername.
  3. cd foldername.
  4. Open the folder in IDE.
  5. Copy the code using "copy" button above and paste it in app.js file(remove the earlier code from app.js).
  6. Open the terminal from IDE.
  7. npm start to run the file.


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 'how to display user info after clicked submit button in react' in kandi. You can try any such use case!

Environment Library

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

  1. The solution is created in Visual Studio Code 1.73.1.
  2. The solution is tested on node v18.12.1 and npm v8.19.2.
  3. React version-18.2.0.


Using this solution, we are able to display user info after clicked submit button 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 display user info after clicked submit button in React.
