Question

我有两个对象，一个是回答一个问题而另一个是最终对象。喜欢

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

我想将answer对象附加到最终对象，如此

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

我该怎么做？

Answer 1

您无法直接追加对象。相反，您需要将对象保存在数组中，如下所示。

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

现在您可以将对象推送到数组，如 -

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

结果将是 -

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);

更新回答：

使用 ecma6 ，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

OR

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

Answer 3

为了将answer对象追加到final中，final必须是一个数组

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

Answer 4

如果您使用ES2015，则可以

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