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')

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)。

使用现代JavaScript的一种干净的方法如下:

const array = [
  { name: "something", value: "something" },
  { name: "somethingElse", value: "something else" },
];

const newObject = Object.assign({}, ...array.map(item => ({ [item.name]: item.value })));

// >> { something: "something", somethingElse: "something else" }

你可能正在寻找这样的东西:

/ /原始 Var arr = [ {key: '11'，值:'1100'，$$hashKey: '00X'}， {key: '22'，值:'2200'，$$hashKey: '018'} ]; / /转换 Var结果= {}; For (var I = 0;I < arrr .length;我+ +){ 结果(arr[我]。Key] = arr[i].value; ｝ console.log(结果);

这应该做到:

Var数组= [ {key: 'k1'， value: 'v1'}， {key: 'k2'， value: 'v2'}， {键:'k3'，值:'v3'} ]; Var mapped = array。Map (item => ({[item。关键:项目。Value})); var newObj =对象。分配({},……映射); console.log (newObj);

var newObj = Object.assign({}, ...(array.map(item => ({ [item.key]: item.value }) )));
