从数组中删除对象

Question

从以下给定对象中删除名为“ itemType”的属性的方法是什么？

 {
    "id": 19,
    "cost": 10,
    "items": 10,
    "numbers": 10,
    "status": false,
    "hours": 10,
    "itemType": {
        "id": 16,
        "name": "PC 350",
        "description": "PC 350"        
    },
    "typeid": 12
}

这样最终数组应该看起来像

 {
    "id": 19,
    "cost": 10,
    "items": 10,
    "numbers": 10,
    "status": false,
    "hours": 10,         
    "typeid": 12
}

Answer 1

这是object而不是array 。 您可以像这样使用delete

   var obj = {
        "id": 19,
        "cost": 10,
        "items": 10,
        "numbers": 10,
        "status": false,
        "hours": 10,
        "itemType": {
            "id": 16,
            "name": "PC 350",
            "description": "PC 350"        
        },
        "typeid": 12
    }

    delete obj.itemType;

Answer 2

无论是对象还是要从中删除属性，还是有一个数组并想删除一个值，删除的方式是-

delete obj.itemType //object.
delete array[3] //delete 4th item from the array.

注意-您提供的结构不是数组，而是对象。
