如何在JavaScript中将哈希转换为单个对象？ [英] How to convert a hash to a single object in JavaScript?

问题描述

我有以下格式的对象数组：

I am having an array of object in the below format:

var log=[
{
  billkey:"Name",
  billvalue:"ABC"
},
{ 
  billkey:"Department",
  billvalue:"Computer"
}];

我希望在单个对象中进行转换，例如：

which I want to convert in a single object like:

var log={
       "Name":"ABC",
       "Department":"Computer"
     };

我尝试过以下方法：

for(var i=0;i<log.length;++i){
   pushToAry(log[i].billkey, log[i].billvalue);
}

function pushToAry(name, val) {
 var obj = {};
 obj[name] = val;
 ary.push(obj);
 }

但每次都会将一个新对象推入ary数组，结果进入：

But it will push a new object every time into the ary array, which results into:

var ary =[
    0:{
      "Name":"ABC"
    },
    1:{ 
      "Department":"Computer"
    }];

我如何将这个对象数组转换为对象？

How could I convert this array of object into an object?

推荐答案

如果您只想使用循环，可以这样做：

If you just want to use a loop, you can do it like this :

var log = [
  {
    billkey: "Name",
    billvalue: "ABC"
  },
  {
    billkey: "Department",
    billvalue: "Computer"
  }];
  var result = {};
  log.forEach(x => result[x.billkey] = x.billvalue);
  console.log(result);
