將對象推入對象數組javascript中的鍵

Question

我有一個存儲各種對象的數組。 如下所示：

[ 'key2': { id: 'WA3WA9WA2WA4WAdWA1WA2WAb-WAeWAdWAaWAf-4WA1WAaWA6-WA8WA8WAeWAc-WAfWAdWAbWAeWAaWA5WA1WAfWAbWAdWAfWA2',
d: undefined,
x: 520,
y: 120 },
  'Key1': { id: 'WA7WA2WAbWAdWAfWA9WA6WA8-WA7WAdWAeWA4-4WA4WA3WAb-WAaWAdWA4WAe-WA2WAbWAdWA5WA1WA0WA7WAbWA3WAdWAfWA9',
d: undefined,
x: 810,
y: 180 } ]

我如何將一個值推入數組，例如：

['key3':{id:something, d:undefined,x:200,y:400}]

這里Key1，Key2，Key3都是動態創建的，並存儲在變量中。

Answer 1

也許你的意思是你有一個像

var yourObj = { 'key1': ...
  'key2': ...
}

你想推另一個嗎？ 如果是這樣的話

yourObj[newKeyGenerated] = theNewObj;

Answer 2

你可以有一個數組

var a = [{ id: 'WA3WA9WA2WA4WAdWA1WA2WAb-WAeWAdWAaWAf-4WA1WAaWA6-WA8WA8WAeWAc-WAfWAdWAbWAeWAaWA5WA1WAfWAbWAdWAfWA2',
d: undefined,
x: 520,
y: 120 },
{ id: 'WA7WA2WAbWAdWAfWA9WA6WA8-WA7WAdWAeWA4-4WA4WA3WAb-WAaWAdWA4WAe-WA2WAbWAdWA5WA1WA0WA7WAbWA3WAdWAfWA9',
d: undefined,
x: 810,
y: 180 } ]

在這種情況下a.push({...})

或物體

var a = { 'key2': { id: 'WA3WA9WA2WA4WAdWA1WA2WAb-WAeWAdWAaWAf-4WA1WAaWA6-WA8WA8WAeWAc-WAfWAdWAbWAeWAaWA5WA1WAfWAbWAdWAfWA2',
d: undefined,
x: 520,
y: 120 },
  'Key1': { id: 'WA7WA2WAbWAdWAfWA9WA6WA8-WA7WAdWAeWA4-4WA4WA3WAb-WAaWAdWA4WAe-WA2WAbWAdWA5WA1WA0WA7WAbWA3WAdWAfWA9',
d: undefined,
x: 810,
y: 180 } }

然后您可以擁有a.key3 = {...}

Answer 3

如果我沒有正確理解，這應該是解決方案： https : //jsfiddle.net/a7uxd4tk/

var data1 = [ {'key1': { id: 'a', d: undefined, x: 520, y: 120 }}];
var data2 =  [ {'key2': { id: 'b', d: undefined, x: 520, y: 120 }}];
var data3 =  [ {'key3': { id: 'b', d: undefined, x: 520, y: 120 }}];
var addData = [];
addData.push(data1[0]);
addData.push(data2[0]);
addData.push(data3[0]);
console.log(addData);

另請注意[ {和} ]

Answer 4

試試吧：

var data = [ {'key2': { id: 'WA3WA9WA2WA4WAdWA1WA2WAb-WAeWAdWAaWAf-4WA1WAaWA6-WA8WA8WAeWAc-WAfWAdWAbWAeWAaWA5WA1WAfWAbWAdWAfWA2',
d: undefined,
x: 520,
y: 120 }},
  {'Key1': { id: 'WA7WA2WAbWAdWAfWA9WA6WA8-WA7WAdWAeWA4-4WA4WA3WAb-WAaWAdWA4WAe-WA2WAbWAdWA5WA1WA0WA7WAbWA3WAdWAfWA9',
d: undefined,
x: 810,
y: 180 }} ];

var newObj = {};
newObj.key3 = {};

newObj.key3.id = 'WA3WA9WA2WA4WAdWA1WA2WAb-WAeWAdWAaWAf-4WA1WAaWA6-WA8WA8WAeWAc-WAfWAdWAbWAeWAaWA5WA1WAfWAbWAdWAfWA2';
newObj.key3.d = undefined;
newObj.key3.x = 520;
newObj.key3.y= 120;

data.push(newObj);
console.log(data);
