使用javascript用另一个表的内容填充该表

我的页面上有一个可选div的网格，属性定义行和列。当我选择其中一些时，将创建三维表格-让我们将其命名为table Copy

当我再次选择一些其他元素时，将创建另一个三维表格-表格粘贴

第一次选择两列两行后，它将

   x,y - positions
   at1,at2,at2 - attributes for later copy

                             Table Copy
                          1                2
                0:[x,y,at1,at2,at3],[x,y,at1,at2,at3]
                1:[x,y,at1,at2,at3],[x,y,at1,at2,at3]

选择三列三行后，它将如下所示

                             Table Copy
                          1                2
                0:[x,y,at1,at2,at3],[x,y,at1,at2,at3]
                1:[x,y,at1,at2,at3],[x,y,at1,at2,at3]

                             Table Paste
                  1                2                 3               
       0:[x,y,at1,at2,at3],[x,y,at1,at2,at3],[x,y,at1,at2,at3]
       1:[x,y,at1,at2,at3],[x,y,at1,at2,at3],[x,y,at1,at2,at3]
       2:[x,y,at1,at2,at3],[x,y,at1,at2,at3],[x,y,at1,at2,at3]

现在我需要一个函数，它可以用tablecopy中的内容填充表粘贴

                             Table Paste
                  1                2                 3               
            0:[tabCopy[0][1]],[tabCopy[0][2]],[tabCopy[0][1]]
            1:[tabCopy[1][1]],[tabCopy[1][1]],[tabCopy[1][1]]
            2:[tabCopy[0][1]],[tabCopy[0][2]],[tabCopy[0][1]]

当然，两个数组的大小有很多可能

表复制可以有4行，表粘贴只能有3行。然后，应“忽略”表副本的第四行

若表只在1行1列中复制，那个么表粘贴中的所有记录看起来都应该是相同的

如果“表粘贴”仅为1行1列，则应仅获取表副本中的第一条记录

我希望我把一切都描述清楚：）

谢谢你的帮助

好吧，让我看看我是否理解你的意思

function copyArrays(from, to) {
    for (var i = 0, j = 0; i < to.length;
         i++, j = (j + 1) % from.length) {
        if ((from[j] instanceof Array) &&
            (to[i] instanceof Array)) {
            copyArrays(from[j], to[i]);
        } else {
            to[i] = from[j];
        }
    }
}

var from = [["x", "y", "at1", "at2", "at3"],
            ["x", "y", "at1", "at2", "at3"],
            ["x", "y", "at1", "at2", "at3"],
            ["x", "y", "at1", "at2", "at3"]];

var to = [["+", "-", "123", "456", "789"],
          ["+", "-", "123", "456", "789"],
          ["+", "-", "123", "456", "789"],
          ["+", "-", "123", "456", "789"],
          ["+", "-", "123", "456", "789"],
          ["+", "-", "123", "456", "789"],
          ["+", "-", "123", "456", "789"],
          ["+", "-", "123", "456", "789"],
          ["+", "-", "123", "456", "789"]];

将为您提供：

[["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"]]

[["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"], 
 ["x", "y", "at1", "at2", "at3"]]
