javascript - React: setting the disabled attribute based on a state

I'd like to set the disabled attribute on a Button based on component's state, something like this:

render() {
  return (
    <button type="button" {this.state.submitting ? 'disabled' : ''} 
      onClick={ this.handleSubmit }>Submit</button>
    );
}

At the moment I get an Unexpected token error on the opening {, what am I missing?

You can set disabled property through boolean value, like this

<button
  type="button"
  disabled={this.state.submitting}
  onClick={this.handleSubmit}
>
  Submit
</button>
