What is the best way to access data from this $scope in AngularJS?

Upon printing selecteditems to the console, this is the output:

[{"model":"Lumia","brand":"Nokia","subModel":["Lumia 735 TS","Lumia 510"],"city":"Bangalore"}]

I have stored it in $scope.details as follows: var selecteditems = $location.search().items; $scope.details =[{"model":"Lumia","brand":"Nokia","subModel":["Lumia 735 TS","Lumia 510"],"city":"Bangalore"}]

How can I extract the model, brand, subModel and city from the variable above?

My expected outcome is:

I tried the following but did not receive any value:

console.log($scope.details.model);

I should get Lumia

console.log($scope.details.brand);

I should get Nokia

console.log($scope.details.subModel);

I should get "Lumia 735 TS", "Lumia 510"

Answer №1

You might need to adjust the way you are querying the values.

There are 2 possible solutions: either modify the data format or refine your data query method.

First option -> modify the data format

$scope.details ={"model":"Lumia","brand":"Nokia","subModel":["Lumia 735 TS","Lumia 510"],"city":"Bangalore"}

This modification will allow you to access the values like 

 $scope.details.model

Alternatively, if you prefer not to change the data format:

$scope.details =[{"model":"Lumia","brand":"Nokia","subModel":["Lumia 735 TS","Lumia 510"],"city":"Bangalore"}]

By following this approach, you can retrieve the values as follows

console.log($scope.details[0].model) // value: Lumia.

Since your data is in an array, you need to specify the index in order to access the JSON data.

Answer №2

When dealing with the $scope.details array, remember to use the index value to retrieve the object containing the specific properties you need.

$scope.details[0].model
$scope.details[0].brand;
$scope.details[0].subModel;

This essentially means accessing the first object in the array and then extracting the 'model' property from it.

Answer №3

In this scenario, you are attempting to access a specific value using the key of an object. However, it is important to note that $scope.details is actually an array of objects. To retrieve the values, utilize the following code snippet:

$scope.details[0].model;
$scope.details[0].brand;
$scope.details[0].subModel;

By implementing the above code, you can easily access and retrieve the desired values.

Answer №4

Give this a shot

Loop through $scope.details using angular.forEach to access each value, key pair:
   - Print the model
   - Print the brand
   - Print the subModel

Answer №5

Here is a sample of the information in your dataset:

$scope.details =[
  {
    "model":"Lumia",
    "brand":"Nokia",
    "subModel":["Lumia 735 TS","Lumia 510"],
    "city":"Bangalore"
  },
  {
    "model":"Galaxy",
    "brand":"Samsung",
    "subModel":["Galaxy S1","Galaxy S2", "Galaxy S3"],
    "city":"Bangalore"
  }
];

To access this data, you can use the following code snippet:

$scope.details.forEach(function(item){
  console.log('Model: ', item.model);
  console.log('Brand: ', item.brand);
  console.log('subModel: ', item.subModel);
  console.log('city: ', item.city);
});
