未捕获的TypeError:无法读取未定义的属性“%1”(即使它已定义)
未捕获的TypeError:无法读取未定义的属性“%1”(即使它已定义)
提问于 2018-12-16 21:57:12
因此，我们的老师给了我们“生活的游戏”项目。我真的为我的项目感到自豪，直到我运行它并得到错误“未捕获TypeError:无法读取未定义的属性'1‘”。对于那些不知道生活游戏是什么的人来说，这是一个“游戏”，你有一个矩阵(这里是一个8x8矩阵)和一些规则来定义每个“人”(矩阵中的数字)是否活着。1表示活着，0表示死了。我将附加整个项目以供参考，但以下是出现错误的部分：
function process(matrix) { //creates the next generation
var neighbors = 0,
position = '',
nextgen = new Array(8); //the matrix has 8 rows
for (i = 1; i <= 8; i++) {
nextgen[i] = new Array(8);
for (j = 1; j <= 8; j++) {
neighbors = neighbors(matrix, i, j);
//Game Rules
if (neighbors < 2) {nextgen[i][j] = 0;
} else if (neighbors == 2) {nextgen[i][j] = 1;
} else if (neighbors <= 3) {nextgen[i][j] = nextgen[i][j];
} else {nextgen[i][j] = 0;}
}
}
return nextgen;
}错误出现在if (neighbors < 2) {nextgen[i][j] = 0;}上。有谁知道为什么吗？我在为nextgen[1]定义8个数组时定义了nextgen[1][1]，对吧？
这是整个项目。名字和一切都是用德语写的，所以请记住这一点。

我找到了问题所在。它在berechne_nachbarn函数中，程序计算游戏板上每个单元格的邻居。更具体地说，在这一部分中：
if (y == 8) {rechts = 8} else {rechts = y - 1}y - 1应该是y + 1。
Ps。这个程序现在能用了，我对此感到非常自豪^_^
