javascript - 从数组中移除一个对象

Question

从下面给定的对象中删除名为“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
}

这样最终的数组应该看起来像

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

Answer 1

这object不是array。你可以delete这样使用

   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

无论它是一个对象并且你想从中删除一个属性，或者你有一个数组并且想要删除一个值，删除的方法是 -

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，而是一个对象。
