将对象推入JavaScript数组的内部数组中

Question

我想将一个对象推入数组的内部数组。

我的数组：

[{"roomid":"652994","Listener":[],"broadcaster":[]}]

我想将以下对象推入Listener数组中：

{"name":"jony","age":"26"}

成为：

{"roomid":"652994","Listener":[{"name":"jony","age":"26"},{"name":"pear","age":"32"}],"broadcaster":[]}

Answer 1

使用数组的第一个索引访问属性Listener，然后访问push()对象：

arr[0].Listener.push(obj);

var arr = [{"roomid":"652994","Listener":[],"broadcaster":[]}]
var obj = {"name":"jony","age":"26"};
var obj2 = {"name":"pear","age":"32"};
arr[0].Listener.push(obj, obj2);
console.log(arr);

Answer 2

只需将它推到想要的位置即可

var array = [{
  "roomid": "652994",
  "Listener": [],
  "broadcaster": []
}]

var toPush1 = {
  "name": "jony",
  "age": "26"
}

var toPush2 = {
  "name": "pear",
  "age": "32"
}

array[0].Listener.push(toPush1);
array[0].Listener.push(toPush2);

console.log(array);
console.log({
  "roomid": "652994",
  "Listener": [{
    "name": "jony",
    "age": "26"
  }, {
    "name": "pear",
    "age": "32"
  }],
  "broadcaster": []
});
