我有一个这样的收藏......

var data = {
    "buckets": [
        {
            "key": "ia-Business",
            "doc_count": 88
        },
        {
            "key": "ia-Health_Sciences_and_Allied_Health",
            "doc_count": 58
        },
        {
            "key": "ia-Media_Communications_and_Creative_Arts",
            "doc_count": 40
        },
        {
            "key": "ia-Information_Technology",
            "doc_count": 35
        }
    ]
};


alert(data.buckets[0].doc_count);

是否可以获取属性doc_count的值对于 key 的对象ia-Business的属性(property)？

Answer 1

使用Array#find，如

buckets.find(bucket => bucket.key === 'ia-Business')
