var?box=document.getElementById("myCanvas");
var?picture=box.getContext('2d');?????????????????????????
for(var?i=0;i<sev.length;i++){
	draw(sev[i],picture);//這里sev寫成了sec
}

function?draw(piece,pic){
	pic.beginPath();
	pic.moveTo(piece.p[0].x,piece.p[0].y);
	for(var?i=1;i<piece.p.length;i++){
		picture.lineTo(piece.p[i].x,piece.p[i].y);//這里應(yīng)該是piece.p[i].x和piece.p[i].y
	}
	pic.closePath();
	pic.fillStyle=piece.color;
	pic.strokeStyle=piece.color;
	pic.fill();
	pic.stroke();
}	???
