React里的事件参数传递和传统的JS参数有些不一样，需要通过bind方法来绑定参数，第一个参数指向this,第二个参数开始才是事件函数接收到的参数

<button onClick={this.handleClick.bind(this,props0,props1,...}></button>

handleClick(porps0,...,event) {
    // your code here
}

showDetail:function(url){
        window.open(url);
    },render:function(){
        var o = this;
        var list = this.props.date.map(function(c){
        return(
                <li onClick={o.showDetail.bind(c,c.txtUrl)}> <h1><span className="am-badge am-badge-success am-radius ">{c.txtSource}</span>{c.title}</h1> <"price am-badge am-badge-warning am-radius ">{c.numPrice}</span> </li>
            );
        });
        return(
            <div id="result"> <ul className="am-list"> {list} </ul> </div>
        );
    }
