Javascript 在二维数组中以字符串形式存储连接的数字。结果仍然是"；“未定义”；

我是一个新手程序员。我正在制作一个2D战舰游戏。我已经成功地随机分配了上述船只的产卵点，我对下一步如何进行有了想法。 我使用一个2D ship数组来存储ship坐标，每行的最后一个地址是它的状态：0=浮动，1=单次命中，2=两次命中，依此类推。但我遇到了一个问题，需要帮助。我似乎无法将任何内容存储到所述阵列。正如您在我的代码板中所看到的，[][]可以工作，但ship[][]不能

我在这一部分有一个错误：

var z = 1; //set to 1 for debugging purposes. z is supposed to be the length of each battleship.
ship[c][z] = 1; // for debug only. line to be removed during final iteration
console.log("c z = " + c + " " + z);
console.log("ship c z = " + ship[c][z]);
if(c == 0)
{
    for(z = 0; z < 4; z++)// this for loop is for battlehsip. more for loops to be added one for each ship type.
        {
            console.log("a b = " + a + " " + b);
            ship[c][z] = ("" + a + b);
            console.log("sketchy array " + ship[c][z]);
            a++;
            console.log("Z = " + z);
        }
}

这是我的全部代码。也许这会让我明白我想要实现的目标。请随意更正我现有的逻辑

请您详细说明您的问题和收到的错误？例如，哪个结果是未定义的？我似乎无法将任何数据存储到ship 2d数组中。正如你所看到的，我有board[x][y]=1，它可以工作，但是ship[c][z]=1不能工作，即使bot c和z有整数值。请你能更具体地说明你的问题和你收到的错误吗？例如，哪个结果是未定义的？我似乎无法将任何数据存储到ship 2d数组中。正如你所看到的，我有board[x][y]=1，它可以工作，但是ship[c][z]=1不能工作，即使bot c和z有整数值，所以我删除了那一行？所以我删除了那一行？
