React Change Input Defaultvalue By Passing Props

React is a powerful JavaScript library that makes building user interfaces a breeze. Today, we'll delve into a nifty trick - changing the default value of an input field in React by passing props. This might sound a bit daunting, but fear not! With some guidance, you'll be implementing this with ease in no time.

Picture this scenario: you have a React component with an input field, and you want to set a default value for it. Instead of hardcoding the value directly into the input field, you can utilize props to make your component more dynamic.

Let's dive into the steps to achieve this:

First things first, create your input field component. You can define it as a functional component like so:

Js

import React from 'react';

const InputComponent = (props) => {
  return ;
}

export default InputComponent;

In this example, we have a simple input component that takes a prop named `defaultValue` and sets it as the value of the input field. But how do we pass this prop to our component and change the default value?

In your parent component where you use `InputComponent`, you can pass the `defaultValue` prop like this:

Js

import React from 'react';
import InputComponent from './InputComponent';

const ParentComponent = () => {
  return ;
}

export default ParentComponent;

By doing this, you're setting the default value of the input field in your `InputComponent` by passing the prop `defaultValue` with the value "Hello, React!" from the `ParentComponent`.

Now, when you render `ParentComponent`, you'll see the input field displaying "Hello, React!" as its default value.

This method allows you to easily change the default value of the input field by simply passing a different value as a prop whenever you use the `InputComponent`. You can even make the default value dynamic by passing a variable instead of a hardcoded string.

Remember, props are a key concept in React for passing data between components. By utilizing them effectively, you can build flexible and reusable components that cater to various scenarios.

In conclusion, changing the default value of an input field in React by passing props is a handy technique that enhances the versatility of your components. By following the steps outlined in this guide, you can seamlessly implement this feature in your React projects. Happy coding!
