如何將對象追加到現有的Angularjs對象中

Question

我有兩個對象，一個是回答一個問題而另一個是最終對象。 喜歡

  answer = {"value":"asda","indicator":"good"};
  final = {}  ;

我想將答案對象附加到這樣的最終對象

final = {{"value":"asda","indicator":"good"},{"value":"sdad","indicator":"worse"}}

我怎樣才能做到這一點 ？

Answer 1

您無法直接追加對象。 相反，您需要將對象保存在數組中，如下所示。

answer = {"value":"asda","indicator":"good"};
final = [];
newObject = {"value":"sdad","indicator":"worse"};

現在你可以將兩個對象推送到數組 -

final.push(answer);
final.push(newObject);

結果將是 -

final = [{"value":"asda","indicator":"good"},{"value":"sdad","indicator":"worse"}];

Answer 2

var answer = {"value":"asda","indicator":"good"};

var final = [] //declare it as Array.

final = final.concat(answer);

更新的答案：

使用ecma6 ，它可以使用spread operator完成。

var answer = {"value":"asda","indicator":"good"};
final = {{"value":"sdad","indicator":"worse"}}   
final  = {...final,answer };//final as an object

要么

var answer = {"value":"asda","indicator":"good"}; 
final = {{"value":"sdad","indicator":"worse"}}   
final  = [...final,answer ]; //final as an array.

Answer 3

為了將answer對象追加到final中，final必須是一個數組

var final =[];
final.push({"value":"asda","indicator":"good"}) 
or
final.push(answer);

Answer 4

如果你使用ES2015，你可以做到

const answer = {"value":"asda","indicator":"good"};
const final = [].concat(Object.assign({}, answer))
