28.React使用map循环创建对象绑定click无效解决方法

var RechargeBtnEle = React.createClass({
    getInitialState: function() {
        return {id:0};
    },
    handleClick(item,item1){
        
        console.log(item,item1)
    },
    render(){
        let btnArr = this.props.data
        var newArr = []
        for(let i=0;i<btnArr.length;i++){
            var item = btnArr[i]
            let styleObj = this.state.id==item.id?["recharge","btn","btn-default","btn-sm","selected"].join(' '):["recharge","btn","btn-default","btn-sm"].join(" ")
            newArr.push(
                <div    className={styleObj}
                        onClick={this.handleClick.bind(this.item,item)}
                        >{`${item.diamond}钻石`}</div>
            )
        }
        
        return(
            <div className="charge-btn">
               {newArr}
            </div>
        )
    }
})
