javascript - angular中controller裡面雙層遍歷為何實作不了

Question

我需要實現這個功能，把獲得的資料進行遍歷出一層，然後再對每一項遍歷，把每一項的資料的某個值賦予給上一層，但是卻實現不了。怎麼辦？
程式碼： 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。
                                "data": {
        "assets": [

為什麼不行呢，你的程式碼，一行沒改：

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",
        "userAssetList": [
        {
            "userDTO": {
                "confirmationDate": null,
                "firstJobDate": null,
                "id": "",
                "userCount": 0,
                "orgList": [],
                "roleList": [],
                "salaryTypeList": [],
                "socialSecurityList": [],
                "failCount": 0,
                "name": "管理员",
                "personalEmail": "932276768@qq.com",
                "personalPhone": "",
                "personalPhoneCountryCode": "86",
                "lastSalary": 0,
                "lastSalaryStartDate": null,
                "currentSalary": 0,
                "currentSalaryStartDate": null,
                "birthDate": null,
                "joiningDate": null,
                "successCount": 0,
                "locked": false,
                "identified": true,
                "active": false
            },
            "count": 3
        },
        {
            "userDTO": {
                "confirmationDate": null,
                "firstJobDate": null,
                "id": "",
                "userCount": 0,
                "orgList": [],
                "roleList": [],
                "salaryTypeList": [],
                "socialSecurityList": [],
                "failCount": 0,
                "name": "沙琪玛",

                "lastSalary": 0,
                "lastSalaryStartDate": null,
                "currentSalary": 0,
                "currentSalaryStartDate": null,
                "birthDate": null,
                "joiningDate": null,
                "successCount": 0,
                "locked": false,
                "identified": true,
                "active": false
            },
            "count": 2
        }
        ]
    }
    ]
}

var datalist=[];
var dataDe = 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]);
