Question

我有一个像这样的数组

var assets = [
    {
    "name": "male",
    "type": [
        {
          name: "tommy",
          y: 512,
        },
        {
          name: "rian",
          y: 812,
        },
      ],
    },
    {
    "name": "female",
    "type": [
        {
          name: "mariam",
          y: 512,
        },
        {
          name: "linda",
          y: 412,
        },
      ],
    }
  ];

并且有一个与其对象名称相同的标题按钮

<button title="male">this is male</button>
<button title="female">this is female</button>

当我点击其中一个时，我想将点击按钮的对象基础推送到另一个数组

$('button').on('click',function(){
    var attr= $(this).attr('title');
    var obj = assets.find(function (obj) { return obj.name === attr; });
    data =[];
    data.push(obj.type);
    console.log(data);    
  });

我得到了这样的输出

[Array(2)]
    0:Array(2)
      0:{name: "mariam", y: 512}
      1:{name: "linda", y: 412}
      length:2
      __proto__: Array(0)
      length:1
    __proto__:  Array(0)

如何将其更改为此

(2) [{…}, {…}]
  0:{name: "mariam", y: 512}
  1:{name: "linda", y: 412}
  length:2
  __proto__:Array(0)

如果另一个数组data（在这种情况下）为空

您可以直接指定如下。

var assets=[{"name":"male","type":[{name:"tommy",y:512,},{name:"rian",y:812,},],},{"name":"female","type":[{name:"mariam",y:512,},{name:"linda",y:412,},],}]

$('button').on('click',function(){
    var attr= $(this).attr('title');
    var obj = assets.find(function (obj) { return obj.name === attr; });
    data =obj.type;
    console.log(data);    
  });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button title="male">this is male</button>
<button title="female">this is female</button>

如果另一个数组data（在这种情况下）非空

您可以使用 Array.concat 。

var assets=[{"name":"male","type":[{name:"tommy",y:512,},{name:"rian",y:812,},],},{"name":"female","type":[{name:"mariam",y:512,},{name:"linda",y:412,},],}]

$('button').on('click',function(){
    var attr= $(this).attr('title');
    var obj = assets.find(function (obj) { return obj.name === attr; });
    data =[];   
    data=data.concat(obj.type); // use concat which will also work if data array is not empty
    console.log(data);    
  });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button title="male">this is male</button>
<button title="female">this is female</button>
