react中怎么传递事件对象

class Popper extends React.Component{

    constructor(){

        super();

        this.state = {name:'Hello world!'};

    }

    preventPop(name, e){    //事件对象e要放在最后

        e.preventDefault();

        alert(name);

    }

    render(){

        return (

            <div>

                <p>hello</p>

                {/* Pass params via bind() method. */}

                <a href="https://reactjs.org" onClick={

                this.preventPop.bind(this,this.state.name)

                }>Click</a>

            </div>

        );

    }

}
