如何替换数组中可以乘以2字符串“even”和“odd”的数字。
var numbers = [
[243, 12, 23, 12, 45, 45, 78, 66, 223, 3],
[34, 2, 1, 553, 23, 4, 66, 23, 4, 55],
[67, 56, 45, 553, 44, 55, 5, 428, 452, 3],
[12, 31, 55, 445, 79, 44, 674, 224, 4, 21],
[4, 2, 3, 52, 13, 51, 44, 1, 67, 5],
[5, 65, 4, 5, 5, 6, 5, 43, 23, 4424],
[74, 532, 6, 7, 35, 17, 89, 43, 43, 66],
[53, 6, 89, 10, 23, 52, 111, 44, 109, 80],
[67, 6, 53, 537, 2, 168, 16, 2, 1, 8],
[76, 7, 9, 6, 3, 73, 77, 100, 56, 100]
];
for (var i = 0; i < numbers.length; i++) {
for (var j = 0; j < numbers[i].length; j++) {
if(numbers[i][j] % 2 === 0) {
numbers[i][j] += " even";
} else {
numbers [i][j] += " odd";
}
console.log(numbers[j][i]);
}
}

如果你的意思是用字符串替换数字,你可以这样做,但数组必须定义为任何:
.two {
max-height: 100%
}

您需要切换索引,以显示实际元素。如果没有,您将获得一些没有更改值的元素。
console.log(numbers[i][j]);
