将动态键：值对传递给对象文字？ [英] Passing in dynamic key:value pairs to an object literal?

问题描述

我正在使用这段代码（如下所示）尝试在for循环中填充名为 Parameters 的对象文字。我需要键：值对与迭代 i 变量的循环一起分配，如下： {key_1：组块[1]，key_2：块[2]} 。但是，我的代码无效。 'key _'+ i 没有反映在文字中。

I am using this slice of code (shown below) in an attempt to populate the object literal named Parameters inside the for loop. I need the key:value pair to be assigned in conjunction with the loops iterating i variable, as such: {key_1:chunks[1],key_2:chunks[2]}. However, my code isn't working. The 'key_'+i is not being reflected in the literal.

这里有一些我遗漏的东西，很明显。有人可以告诉我它是什么吗？...谢谢。

There's something I am missing here, obviously. Can someone tell me what it is?...Thanks.

var Parameters=[];
var len = chunks.length;
for (var i = 0; i < len; i++) {
    var key='key_'+i
    obj= { key : chunks[i]};
   Parameters.push(obj)
}

推荐答案

编辑：使用 var obj = {}; obj [key] = chunks [i];

因为ECMAScript处理键在此 {key：1} 中为字面值。

Because ECMAScript treats the key in this {key:1} as literal.
