javascript - Why can't double-layer traversal be implemented in the controller in angular?

Question

I need to implement this function, traverse the obtained data to one level, and then traverse each item, and assign a certain value of each item's data to the previous layer, but it cannot be implemented. what to do?
Code: var datalist=[];

                var dataDe = data.body.data.assets;
                for(var i = 0;i<dataDe.length;i++){
                    for(var j= 0;j<dataDe[i].userAssetList.length;j++){
                        dataDe[i].userDtoName = dataDe[i].userAssetList[j];
                        datalist.push(dataDe[i]);
                    }
                }
                $scope.datalist=datalist;
              事实证明第二个循环里面的值alert可以出来。但是赋值给外层的元素就不行了。怎么解决。求大神。
              数据结构如下：我是想把userassetlist里面的数组进行遍历然后赋值给上一层。

Why not? Your code has not changed a single line:

var data = {
    "assets": [
    {
        "id": "001",
        "assetCount": 14,
        "availableCount": 9,
        "price": 2,
        "startDate": null,
        "age": 0,
        "description": "",
        "assetType": "台式机",
        "assetName": "赛尔",
        "assetModel": "Z-01",
