小编Cha*_*one的帖子

我有一个二维数组，其结构如下：

我想将值相对于它们的索引相加。（-10000 + 100 + 100 + -100）。然后将它们存储在一个单独的数组中，如下所示：

[[500], [-10100], [9000], [18000], [18000]]

我想我必须使用map和reduce来实现这一目标，但是我运气并不好。

这是我目前拥有的：

for (var i=1; i<totals.length; i++) {
    for (var z=0; z<totals[i].length; z++) {
        console.log(totals[i][z] = totals[i-1][z] + totals[i][z]);
    }
}

但是，这似乎输出以下内容：

如果有人可以将我推向正确的方向，那就太好了。

我似乎在Magento上有索引问题.所有可用的索引索引都很好,除了一个:

Sm Shopby

通过以下错误编制索引时,我无法完全看出问题所在.

Sm Shopby index process unknown error:
