React - Change the button text onClick

In this tutorial, we are going to learn about how to change the text of a button onClick in React.

Consider, we have the following component in our react app:

import React from 'react';

function Home(){
    return (
        <div className="container">
          <button>SignUp</button>
        </div>
    )
}

export default Home;

To change the button text in React, add the onClick event handler to it and change the text conditionally whenever a button is clicked.

Here is an example:

import React, { useState } from "react";

function Home() {
  const [active, setActive] = useState(false);
  const handleClick = () => {
    setActive(!active);
  };

  return (
    <div className="container">
      <button onClick={handleClick}>
         { active ? "Logout" : "Login"}
      </button>
    </div>
  );
}

export default Home;

In the example above, we added a handleClick event handler to the onClick prop and state active to the button text, so whenever a button is clicked it runs the handleClick function and changes the active state from false to true or vice versa.

Based on the active state we are changing the button text using ternary expression.

{ active ? "Logout" : "Login"}

If active is false it chooses Login text, if its true it chooses Logout text.
