JavaScript未捕获类型错误:无法设置属性'-1';未定义的
我正在练习jquery,并试图构建一个非常基本的Tic-Tac-Toe游戏 我想将html表设置为数组形式的网格索引,并根据玩家的点击改变它们的值。目前,我有颜色变化,这取决于轮换工作,但我不断得到这个未捕获的类型错误,引用我的条件语句中的JavaScript未捕获类型错误:无法设置属性'-1';未定义的,javascript,jquery,html,arrays,tic-tac-toe,Javascript,Jquery,Html,Arrays,Tic Tac Toe,我正在练习jquery,并试图构建一个非常基本的Tic-Tac-Toe游戏 我想将html表设置为数组形式的网格索引,并根据玩家的点击改变它们的值。目前,我有颜色变化,这取决于轮换工作,但我不断得到这个未捕获的类型错误,引用我的条件语句中的board[row][col]=x 我的代码: $(document).ready(function(event) { var count = 0; var board = [ [0, 0, 0], [0,

问题是在读取索引值的位置,需要在单击处理程序中读取它
$(document).ready(function (event) {
var count = 0;
var board = [
[0, 0, 0],
[0, 0, 0],
[0, 0, 0]
];
//here this is the document object
$('td').click(function () {
//reading index values should be inside the click handler, here `this` refers to the clicked `td` element
var row = $(this).parent().index();
var col = $(this).index();
// if count is even, player 1 is yellow
// if count is odd, player 2 is blue
if (count % 2 === 0) {
$(this).addClass('yellow');
count++;
board[row][col] = 1;
} else {
$(this).addClass('blue');
count++;
board[row][col] = 2;
}
});
});
还应该使用类似的东西:
td{width:30px;height:30px;background color:#eee;}
@Ultimater我确实有比那里多得多的CSS:)这应该可以在
元素上不设置任何属性。没有一个是完全必要的。啊,我明白了。非常感谢。
$(document).ready(function (event) {
var count = 0;
