"Make a phone call following the completion of an HTTP

Upon receiving and storing data, I am looking to execute a function but the code I currently have is not producing the desired result.

Could someone provide some insight into what I might be doing incorrectly?

Here's my current code snippet:

    $http({
      method: 'GET',
      url: 'JsonLocation'
    }).then(
        function successCallback(response) {
            // this callback will be called asynchronously
            // when the response is available.
            self.responseData = response.data;
        }, 
        function errorCallback(response) {
            // called asynchronously if an error occurs
            // or server returns response with an error status.
            console.log(response);
        }
    ).then(
        function completeCallback() {
            // called when the http request is finished.
            restyleData();
        }
    );

Although triggering the restyleData() function manually via developer options works after the page has loaded and everything is set up, I'd prefer to automate this process after all resources are loaded.

Answer №1

If you are looking to make a modification, I would recommend switching to the following code snippet:

$http({
  method: 'GET',
  url: 'JsonLocation'
}).then(
    function successfulResponse(response) {
        // This function will be executed asynchronously
        // once the response is received.
        self.resultData = response.data;
        // Invoke restyle function after saving the result
        applyNewStyle();
    }, 
    function errorResponse(response) {
        // Triggered asynchronously in case of an error
        // or when server returns with an error status.
        console.log(response);
    }
);

To populate data in your HTML after using `then`, make sure to use `catch` and `finally` as well. Once you set `$scope.responseData = data`, you can easily display the data in your HTML by referencing it like `{{responseData.description}}`. If you've defined `self` as `this`, then use `{{self.responseData.description}}` instead.

Another approach is to encapsulate your $http call within a function named `restyleData` and then execute that function to show the fetched data.

$http({
  method: 'GET',
  url: 'JsonLocation'
}).then(
    function successCallback(response) {
        // This callback will be triggered asynchronously
        // once the response is received.
        self.responseData = response.data;
    })
     .catch( 
    function errorCallback(response) {
        // This is called asynchronously if an error occurs
        // or if the server returns a response with an error status.
        console.log(response);
    })
     .finally(
    function completeCallback() {
        // Executed when the http request is completed.
    });

restyleData();
