Toggle Class On Click using React JS | React JS Tutorial

How to add class onclick in react js? Or how can we toggle class on click using React JS? Adding and removing class in react js is very common practice. How to add active class in react js? How to add css classes dynamically in react js? Let's see how to toggle a class very easily in React JS. In this tutorial we will add and remove class conditionally in React JS. We created a button component. To handle button click, we added onClick event handler for the button. We need a state for the button. We can use a React Hook like useState to store state in ReactJS. We declared state with a boolean value / false for the button class.

If we click the button, button state should be changed from false to true and true to false. In handleClick function, toggle state. Now state is being changed. We stored the result in variable toggleClassCheck and if state is true we toggled class for the button. Now let's say button already has got a class applied to it. We want to add or remove active class here without affecting the class that is already there. To do that change, we will need template literal or template string. When we need to insert dynamic content with regular text, we can use template literal. And we will have a space between these classes. Space comes with active class. We used space before active class in Conditional operator or ternary operator. Call this button in main component. Clicking button will toggle class active. We can replicate this button. And class will work fine for different buttons. So this is how you can add or remove class in react js on click or toggle class in react js.

Hey, I love your vdo! Is there any possible way to turn other button off and allowing only one button to be on?

Hi I am new to this one. Can you please tell me why can't we use directly setBtnState(true) instead of setBtnState(btnState => !btnState) in handleClick function.
