X轴的不能点击呢
为什么我的最后是只能走Y竖轴，不能走X横轴的呢？每次点击X轴，chessBoard[i,j]不能初始化为0，但是点击Y轴的就可以初始化为0呢？
var me = false;
var chessBoard = [];
for(var i=0;i<15; i++){
chessBoard[i] = [];
for(var j=0; j<15; j++){
chessBoard[i,j] = 0;
}
}
var chess = document.getElementById('chess');
var context = chess.getContext('2d');
context.strokeStyle = "#BFBFBF";
var logo = new Image();
logo.src = "image/yixiu.png";
logo.onload = function(){
context.drawImage(logo,0,0,450,450);
drawChessBoard();
/*context.beginPath();
context.arc(200, 200, 100,0, 2 * Math.PI);
context.closePath();
var gradient = context.createRadialGradient(200, 200, 50, 200, 200, 10);
gradient.addColorStop(0,"#0A0A0A");
gradient.addColorStop(1,"#636766");
context.fillStyle = gradient;
context.fill();*/
}
var drawChessBoard = function(){
for(var i=0; i<15; i++){
context.moveTo(15 + i*30,15);
context.lineTo(15 + i*30,435);
context.stroke();
context.moveTo(15,15 + i*30);
context.lineTo(435,15 + i*30);
context.stroke();
}
}
var oneStep = function(i,j,me){
context.beginPath();
context.arc(15 + i*30, 15 + j*30, 13,0, 2 * Math.PI);
context.closePath();
var gradient = context.createRadialGradient(15 + i*30 + 2, 15 + j*30 -2, 13, 15 + i*30 + 2, 15 + j*30 - 2, 0);
if(me){
gradient.addColorStop(0,"#0A0A0A");
gradient.addColorStop(1,"#636766");
}else{
gradient.addColorStop(0,"#D1D1D1");
gradient.addColorStop(1,"#F9F9F9");
}
context.fillStyle = gradient;
context.fill();
}
chess.onclick = function(e){
var x = e.offsetX;
var y = e.offsetY;
var i = Math.floor(x / 30);
var j = Math.floor(y / 30);
//alert("me="+me+',i='+i+",j="+j+",="+ chessBoard[i,j]);
debugger;
if(chessBoard[i,j] == 0){
oneStep(i,j,me);
if(me){//如果是黑棋
chessBoard[i,j] = 1;
}else{//如果是白棋
chessBoard[i,j] = 2;
}
me = !me;
}
}
