got error of scope not defined when i use for response message:
$scope.responsemessage = response;
then I added $scope here like this:
app.service('fileUpload', ['$http', '$scope', function ($http, $scope) {
When I added above $scope got this error Error: [$injector:unpr] http://errors.angularjs.org/1.4.8/$injector/unpr?p0=.................
Service don't have scope.
If you wanna to use scope inside service , have to pass it from controller .
Like this
In controller
fileUpload.checkFile($scope.responsemessage);
In service
function checkFile(respMsg)
{
console.log(respMsg);
}
$scopes are not available from services, it should only be used inside controllers.
In angular $scope is available in controllers and services are used as a dependency for data provider.
You just can't use $scope in the service and from service you can return a promise object like:
app.service('fileUpload', ['$http', function($http) {
return $http.post('url')
}]);
Now you can inject this service to update a variable on the controller's $scope:
app.controller('cntrl', ['$scope', 'fileUpload', function($scope, fileUpload){
$scope.responsemessage = fileUpload.then(function(data){
return data;
})
}]);
You can not use $scope in Services as well as in Factories. You can call service by giving $scope value as a parameter and save the return value to the $scope variable
