使用reduce的简单方法

// Input : 
const data = [{key: 'value'}, {otherKey: 'otherValue'}];

data.reduce((prev, curr) => ({...prev, ...curr}) , {});

// Output
{key: 'value', otherKey: 'otherValue'}

使用Object.assign更简单

Object.assign({}, ...array);

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);

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" }

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
}, {});

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);

在2022年附近，我喜欢这种方法，特别是当对象数组是动态的时，这也是基于@AdarshMadrecha的测试用例场景的建议，

const array = [ 
  { key : '11', value : '1100', $$hashKey : '00X' },
  { key : '22', value : '2200', $$hashKey : '018' }];
  
let obj = {};
array.forEach( v => { obj[v.key] = v.value }) //assign to new object
console.log(obj) //{11: '1100', 22: '2200'}
