Disable Button App

This week we created a Disable Button app. When the data changes, we handle it and disable the button in react.

To create a DisableButton component; We have to :

• Input data is usually handled by the component. So all the data is stored in the component state.
• Create a state that holds the value of the input with inital value an empty string.
• The value of the input is the value of the state.
• Adding event handlers in the onChange attribute to control input changes and update our state.
• The submit button is disabled if the length of value in the input is empty.
• Now, When the data changes, we handle it and disable the button.

Code

import React, {useState} from 'react';

const DisableButton = () => {
    const [value, setValue] = useState("");

    return (
        <div>
            <h2>Handle Input</h2>
            <input
                type="text"
                placeholder="Enter Your Title"
                value={value}
                onChange={(e) => setValue(e.target.value)}
            />
            <button disabled={value.length < 1}>
                Submit
            </button>
            <p>{value}</p>
        </div>
    );
}

export default DisableButton;
