Hey there, I'm new to Angular and had a question. Is it possible to use the $http service in Angular to trigger a function whenever there is any change in the ready state/status, not just for success or failure? If so, what would be the equivalent angular code for the following vanilla JavaScript code:
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
if (xhr.readyState < 4 && xhr.status != 200)
alert('Loading');
}
xhr.open...
xhr.send...
In version 1.3+ of Angular, the event mentioned is no longer utilized and not accessible, as it is only compatible with state 4 in version 1.2.
If you absolutely needed to achieve a similar effect, your best option would be to modify or enhance $httpBackend...

Here's another trick I've found success with: adding $scope.$apply() after making a function call that would typically involve $http:
// utilizing $http
var promise = $http.get(url).then(success, ...);
// alternative method without $http
$.ajax({
url: url,
success: function() {
success();
$scope.$apply(); // in case you were using $http, this step becomes unnecessary
},
...
});
