所以我有
var arrays = [
[ Material A, 1, 2, 3, 4, 5 ],
[ Material B, 6, 7, 8, 9, 10 ],
[ Material C, 11, 12, 13, 14, 15 ]
];
我需要把它放在这种多维关联数组格式
中var bigdata = [
{ "Name": "MaterialA", "Row1": 1, "Row2": 2, "Row3": 3, "Row4": 4, "Row5": 5 },
{ "Name": "MaterialB", "Row1": 6, "Row2": 7, "Row3": 8, "Row4": 9, "Row5": 10 },
{ "Name": "MaterialC", "Row1": 11, "Row2": 12, "Row3": 13, "Row4": 14, "Row5": 15 }
];
我正在尝试
var bigdata = new Array(3);
for (i=0; i<3; i++)
{
// do name
bigdata[i][0] = {"Name" : arrays[i][0]};
for (j=1; j<6; j++ )
{
// rest of that row
}
}
但到目前为止,当我尝试存储第一个&#34; Name&#34;:&#34; MaterialA&#34; 。我做错了什么或者甚至可以做到这一点?谢谢你的帮助。

这对我有用。请注意,我从[0]
中删除了bigdata[i][0]
,并将行分配代码添加到“j”循环中。
for (i=0; i<3; i++)
{
// do name
bigdata[i] = {"Name" : arrays[i][0]};
for (j=1; j<6; j++ )
{
// rest of that row
bigdata[i]['Row' + j] = arrays[i][j];
}
}

设置关联数组/对象属性的正确方法如下:
bigdata[i]["Property"] = value // this allows dynamic property name
bigdata[i].Property = value // or like this, if property is hard-coded
所以在你的情况下,它应该是:
bigdata[i] = {} // initialize a blank object
bigdata[i].Name = arrays[i][0];
for ( j=1; j<6; j++ )
bigdata[i]["Row" + j] = arrays[i][j];
