使用Underscore.js:

var myArray = [
  Object { key="11", value="1100", $$hashKey="00X"},
  Object { key="22", value="2200", $$hashKey="018"}
];
var myObj = _.object(_.pluck(myArray, 'key'), _.pluck(myArray, 'value'));

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" }

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);

更新:世界一直在转。使用函数式方法。

以前的回答

给你:

var arr = [{ key: "11", value: "1100" }, { key: "22", value: "2200" }];
var result = {};
for (var i=0, len=arr.length; i < len; i++) {
    result[arr[i].key] = arr[i].value;
}
console.log(result); // {11: "1000", 22: "2200"}

坐地lodash !

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