如何使用两个数组在JavaScript中创建一个对象文字数组[重复]

This question already has an answer here:

这个问题在这里已有答案:

I want to create an object literal array like this

我想创建一个像这样的对象文字数组

var data = [
      {name: 'John A. Smith', state: 'CA'},
      {name: 'Joan B. Jones', state: 'NY'}
    ];

name and state are stored in an array columns.

名称和状态存储在数组列中。

John A. Smith and CA are stored in array data.

John A. Smith和CA存储在数组数据中。

I'm trying to write this way, but it seemed like I couldn't use the columns[i] before the :,

我试着用这种方式写,但似乎我不能在:之前使用列[i]:

var temp = [];
for (var i = 0; i < data.length; i++) {
    temp.push({
        columns[i]: data[i]
    });
}

Thanks Lochemage, it works for my columns. Here is my entire code:

谢谢Lochemage,它适用于我的专栏。这是我的整个代码:

var temp = [];
var tempObj = {};
for (var i=0; i<colHeads.length; i++) { // columns
    var dataArr = '$colData.get(i)'.split(",");
    for (var j = 0; j < dataArr.length; ++j) { // data
        tempObj[colHeads[i]] = dataArr[j];
    }
    temp.push(tempObj);
}

This '$colData.get(i)' seems to work with direct index (0, 1, ..), but it won't work with i.

这个'$ colData.get(i)'似乎适用于直接索引(0,1,...),但它不能用于i。

By the way, $colData is a string array from velocity markup; it contains strings. In this particular problem, it contains

顺便说一句,$ colData是来自速度标记的字符串数组;它包含字符串。在这个特殊的问题中,它包含

[0]: CA, NY
[1]: John A. Smith, Joan B. Jones

And I need the final result is to be the data array stated at the top.

我需要最终的结果是在顶部说明的数据数组。

You have to use the bracket operator with your columns value instead:

您必须将支架运算符与列值一起使用:

var temp = [];
var tempObj = {};
for (var i = 0; i < data.length; ++i) {
  tempObj[columns[i]] = data[i];
}
temp.push(tempObj);
