我有一个对象数组:

[ 
  { key : '11', value : '1100', $$hashKey : '00X' },
  { key : '22', value : '2200', $$hashKey : '018' }
];

如何通过JavaScript将其转换为以下内容?

{
  "11": "1100",
  "22": "2200"
}

当前回答

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

let arr = {};

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

console.log(arr);

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);

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

http://jsfiddle.net/3QKmX/1/

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

let arr = {};

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

console.log(arr);

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);


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

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
}, {});
