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
}, {});

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 }) )));

你可以在一行中将数组的对象合并为一个对象:

const obj = Object.assign({}, ...array);

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Object.fromEntries:

Const数组= [ {key: "key1"， value: "value1"}， {key: "key2"， value: "value2"}， ]; const obj = Object.fromEntries(array.map(item => [item. map])键,item.value])); console.log (obj);

let array = [
  { key: "key1", value: "value1" },
  { key: "key2", value: "value2" },
];

let arr = {};

arr = array.map((event) => ({ ...arr, [event.key]: event.value }));

console.log(arr);
