constructor() { super(); this.btn = []; } onRunClick(act, index, e) { this.btn[index].setAttribute("disabled", true); } render () { return ( <div> { this.state.acts.map((act, index) => { let boundActRunClick = this.onRunClick.bind(this, act, index); return ( <p key={act._id}> Name: {act.name}, URL(s): {act.urls} <button ref={(ref) => this.btn[index] = ref} onClick={boundActRunClick}>Run</button> </p> ) }) } </div> ); } |
