你可以使用mapKeys lodash函数。只有一行代码!

请参考这个完整的代码示例(复制粘贴到repl。它或类似):

import _ from 'lodash';
// or commonjs:
// const _ = require('lodash');

let a = [{ id: 23, title: 'meat' }, { id: 45, title: 'fish' }, { id: 71, title: 'fruit' }]
let b = _.mapKeys(a, 'id');
console.log(b);
// b:
// { '23': { id: 23, title: 'meat' },
//   '45': { id: 45, title: 'fish' },
//   '71': { id: 71, title: 'fruit' } }

我喜欢用函数方法来完成这个任务:

var arr = [{ key:"11", value:"1100" }, { key:"22", value:"2200" }];
var result = arr.reduce(function(obj,item){
  obj[item.key] = item.value; 
  return obj;
}, {});

注意:Last{}是reduce函数的初始obj值，如果你不提供初始值，第一个arr元素将被使用(这可能是不可取的)。

下面是如何动态地接受上面的字符串，并将其插入到一个对象:

var stringObject = '[Object { key="11", value="1100", $$hashKey="00X"}, Object { key="22", value="2200", $$hashKey="018"}]';

function interpolateStringObject(stringObject) {
  var jsObj = {};
  var processedObj = stringObject.split("[Object { ");
  processedObj = processedObj[1].split("},");
  $.each(processedObj, function (i, v) {
      jsObj[v.split("key=")[1].split(",")[0]] = v.split("value=")[1].split(",")[0].replace(/\"/g,'');
  });

  return jsObj
}

var t = interpolateStringObject(stringObject); //t is the object you want

是昨天做的

// Convert the task data or array to the object for use in the above form
 const {clientData} = taskData.reduce((obj, item) => {
 // Use the clientData (You can set your own key name) as the key and the 
 // entire item as the value
 obj['clientData'] = item
 return obj
}, {});

坐地lodash !

const obj = _.keyBy(arrayOfObjects, 'keyName')
