How can I do not change the value of a variable in AngularJs

  • 772

I need to create a variable that saves the state of the funciónone that I execute in the $interval call $scope.getSignatureCallStatus();that function executes a request that saves the state in a variable $scope.callStatus = res.data;... there
are 3 states:

{
    success
    fail
    hangup
}


So if the variable $scope.callStatus = 'success'that I save in a new variable that value or TRUEsomething like $scope.callStatusSucces = $scope.callStatus == 'success', but since it is in an interval the value changes dynamically, then I want the new variable not to change the value...

$scope.promise = $interval(function() {
    $scope.getSignatureCallStatus();
    $scope.showStatus = true;
}, 2500);


This is the function$scope.getSignatureCallStatus();

$scope.getSignatureCallStatus = function() {
        $http.get('url', {
            params: {
                param: param
            }
        }).then(function(res){
            $scope.callStatus = res.data;
        });
    };

    From your question I understand that you only want to know when $scope.callStatus'success' has ever been. In this case, you can do the same as you stated in the question: declare a variable $scope.callStatusSucces(name proposed by you in the question) and assign it true when $scope.callStatus == 'success'.

    The function would look like this:

    $scope.getSignatureCallStatus = function() {
    $http.get('url', {
        params: {
            param: param
        }
    }).then(function(res){
        $scope.callStatus = res.data;
        if (!$scope.callStatusSucces) { // si `$scope.callStatusSucces` no ha sido setteado o `$scope.callStatus` nunca ha sido 'success'
            $scope.callStatusSucces = $scope.callStatus == 'success'
        }
    });
};
