Changing style of a button on click

Question

Is it possible to change background-color of my button onClick function?

ex. click background-color: black, another click background-color: white

I've tried something like this.style, no result.

I've managed to get overlay working and insert needed data inside of it. But didn't managed to find any post that could help me. I am using react-bootstrap. This is my code.

  const metaDataOverlay = (   <div>   <style type="text/css">{`   .btn-overlay {     background-color: white;     margin-right: -15px;     margin-left: -15px;     padding-bottom: -20px;     padding: 0;   }   `}</style>        <ButtonToolbar>         <ButtonGroup>         <OverlayTrigger trigger={['hover', 'focus']} placement="left" overlay={popoverHoverFocus}>           <Button bsStyle="overlay" onClick={ clicked } onKeyPress={ keypress }>             <div className={bemBlocks.item().mix(bemBlocks.container("item"))} data-qa="hit">               <a href={url} onClick={(e)=>{e.preventDefault(); console.log("123")}}>                 <div>                   <img data-qa="poster" className={bemBlocks.item("poster")} src={result._source.poster} width="240" height="240"/>                 </div>               </a>             </div>           </Button>         </OverlayTrigger>         </ButtonGroup>       </ButtonToolbar>      </div>   )

You can try to use state to store the color. Maybe this would give you the idea how to solve the problem :

class Test extends React.Component {     constructor(){         super();          this.state = {            black: true         }     }      changeColor(){        this.setState({black: !this.state.black})     }      render(){         let btn_class = this.state.black ? "blackButton" : "whiteButton";          return (              <button className={btn_class} onClick={this.changeColor.bind(this)}>                   Button              </button>         )     } }  React.render(<Test />, document.getElementById('container')); 

Here is a fiddle.

You also have access to event and current target of the event

handleClick = (event) => {    // accessible    event.target.style    event.target.classList //to change style via css }
