var arr = [{
    "aaa": {
        "name": "小敏",
        "price": "18",
        "count": 2,
        "num": 5
    },
    "bbb": {
        "name": "小李",
        "price": "18",
        "count": 1,
        "num": 11
    },
    "ccc": {
        "name": "小华",
        "price": "18",
        "count": 1,
        "num": 18
    }
}]

var arr1 = [
      {"id":"aaa","count":2},
      {"id":"bbb","count":1},
      {"id":"ccc","count":1}
]

var arr = [{
    "aaa": {
        "name": "小敏",
        "price": "18",
        "count": 2,
        "num": 5
    },
    "bbb": {
        "name": "小李",
        "price": "18",
        "count": 1,
        "num": 11
    },
    "ccc": {
        "name": "小华",
        "price": "18",
        "count": 1,
        "num": 18
    }
}];


var tArr = [];


arr.forEach((item,index)=>{
    tArr.push(
        Object.keys(item).map((v,i)=>{
        return {
            id : v,
            count : item[v].count
        }
    })
    );
});


console.log(tArr);
