在二维数组中使用for循环分配坐标

Question

简单地说，我想用for循环来分配x坐标和y坐标。但它不像c#、c++这样的语言那样工作。这是我的代码:

  var coordinate=[[]];
  var x, y;
      for (x=1; x <= 7; x += 1) {
          for (y=1; y <= 5; y += 1) {
              coordinate[x][y] = "("+x+","+y+")";
          }
      }

我该怎么做呢?

Answer 1

  var coordinate=[];
  var x, y;
      for (x=1; x <= 7; x += 1) {
            coordinate[x] = [];
          for (y=1; y <= 5; y += 1) {
              coordinate[x][y] = "("+x+","+y+")";
          }
      }
