var PieceList = React.createClass({

  render: function() {

    var pieces;
    if (this.props.pieces && this.props.onDeletePiece2) {
      var pieces = this.props.pieces.map(function (piece) {
        return (
          <Piece pieceData={piece} onDeletePiece3={this.props.onDeletePiece2} />
        )
      });
    }
    return (
      <div className="piecesTable">
        {pieces}
      </div>
    );  
  }
});

我很难过如何让它发挥作用.问题是{this.props}在map函数内部不可用.

这里的foreach会更好吗？难倒,请停下来!
