Navigating through JSON objects in AngularJS is as simple as pie

I have a JSON structure that looks like this:

var myJson = {
   "Number of Devices":2,
   "Block Devices":{
      "bdev0":{
         "Backend_Device_Path":"/dev/ram1",
         "Capacity":"16777216",
         "Bytes_Written":9848,
         "timestamp":"4365093970",
         "IO_Operations":87204,
         "Guest_Device_Name":"vdb",
         "Bytes_Read":107619,
         "Guest_IP_Address":"192.168.26.88"
      },
      "bdev1":{
         "Backend_Device_Path":"/dev/ram2",
         "Capacity":"16777216",
         "Bytes_Written":10062,
         "timestamp":"9365093970",
         "IO_Operations":93789,
         "Guest_Device_Name":"vdb",
         "Bytes_Read":116524,
         "Guest_IP_Address":"192.168.26.100"
      }
   }
}

I am attempting to extract the information for Block Devices labeled as bdev0, bdev1... along with their corresponding values. Typically, using Object.keys in vanilla JavaScript makes this task straightforward. However, it appears that I cannot utilize this function in Angular. Instead, I attempted to use angular.forEach, but encountered an issue resulting in 'undefined'.

Here is the progress I have made so far:

function getData(){
  $http.get(path)
  .success(function(data){
    $scope.devices = data
    angular.forEach($scope.devices, function(item){
                   console.log(item['Block Devices']);
               })


  })
}

Answer №1

To retrieve the desired properties, utilize forEach like demonstrated in the code snippet below:

angular.forEach($scope.devices['Block Devices'], function(value, key) {
   console.log(value, key);
   // This will display the value of $scope.devices['Block Devices'][key]
   // along with the corresponding key name such as 'bdev0', 'bdev1' etc.
})

This method allows you to access the value of bdev0, bdev1 as the value and the device name as the key within your callback function.

Angular, a powerful javascript framework, is capable of handling tasks similar to vanilla javascript with ease. If you're wondering how to iterate through elements using Angular, here's an example:

angular.forEach($scope.devices['Block Devices'], function(value, key){
       console.log(key);
})

By running this code snippet, you can expect to see outputs like bdev0, bdev1, and so on.
