How to access nested JSON data with dynamic variables

Question

I am stuck on a issue where i need to access a nested JSON with dynamic variables. This is my JSON:

{
    "Account2": [{
        "accountId": "17467****",
        "containerId": "7454***",
        "path": "accounts\/17467*****\/containers\/7454***",
    }, {
        "accountId": "17467****",
        "containerId": "7519***",
        "path": "accounts\/17467****\/containers\/7519***",
    }],
    "Account 1": [{
        "accountId": "17661****",
        "containerId": "7483***",
        "path": "accounts\/17661****\/containers\/7483***",
    }]
}

Using AngluarJS on front-end i use this to print a table, here i can use the "path" variable to use a href and then make second API call based on url parameters like this:

<td><a href="/gui/tags/{{v1.path}}">View Container</a></td>

v1.path = accounts/17467*****/containers/7454***

Now to my problem, i want to send this call before clicking on table to show some data. The problem is that when accessing the JSON that has dynamic variable as you can see: "Account2", "Account1". I cannot use: `$scope.GTMcontainersAccount = response.data.ACCOUNT1;

because "account1" is dynamic and changes from user to user.

Someone has an idea? regEx?

UPDATED:

when i use:

 $scope.GTMcontainersAccount = response.data;
                    $scope.keys = Object.keys(response.data);
                    for(n in $scope.keys)
                    {
                       $scope.asim = $scope.keys[n];
                       console.log($scope.asim);
                       console.log(response.data[$scope.asim]);
                    }

This gives me this result:

So i have to write like:

console.log(response.data[$scope.asim][0].accountId);

But this gives me only row of "account2" not "account1"

@Adriani6 console.log(Object.keys(response.data)); gives me "account1" and "account2" not the key:value itself — Asim

yes, Object.keys(obj).forEach(key => console.log(obj[key])) — dfsq

You need to use Object.keys() to get the keys of your object, then for each key get the relevant array and loop over its items:

Object.keys(data).forEach(function(key) {
  let accounts = data[key];
  if (accounts && accounts.length) {
    accounts.forEach(function(account) {
      console.log(account);
    });
  }
});

Demo:

let data = {
  "Account2": [{
    "accountId": "17467****",
    "containerId": "7454***",
    "path": "accounts\/17467*****\/containers\/7454***",
  }, {
    "accountId": "17467****",
    "containerId": "7519***",
    "path": "accounts\/17467****\/containers\/7519***",
  }],
  "Account 1": [{
    "accountId": "17661****",
    "containerId": "7483***",
    "path": "accounts\/17661****\/containers\/7483***",
  }]
};

Object.keys(data).forEach(function(key) {
  let accounts = data[key];
  if (accounts && accounts.length) {
    console.log(key+": ");
    accounts.forEach(function(account) {
      console.log(account);
    });
  }
});
