[英]Calling a Service function from a Controller in AngularJS
Controller Code 控制器代码
'use strict';
angular.module('MyApp').controller('ArticleContribEmailController', [
'$scope', 'ArticleAppState', 'fbsUserDataService', 'contribEmailService',
function ($scope, ArticleAppState, fbsUserDataService, contribEmailService ) {
this.userChanged = function () {
if (fbsUserDataService.initialized && fbsUserDataService.user && ArticleAppState.page_data) {
// user has authenticated.
contribEmailService.initForm();
}
};
// watch for when user data is available, run userChanged.
$scope.$watch(function() { return fbsUserDataService.user; }, this.userChanged);
$scope.$watch(function() { return fbsUserDataService.initialized; }, this.userChanged);
}
]);
Service Code 服务编号
'use strict';
angular.module('forbesArticleApp').service('contribEmailService', [
'$injector', '$route', 'ArticleAppState', 'fbsUserFormFactory', 'fbsUserDataService',
function initForm ($injector, $route, ArticleAppState, fbsUserFormFactory, fbsUserDataService) {
console.log("Hello world!");
}
]);
I only want to fire the contribEmailService.initForm()
function from the call in my controller, but it is firing as soon as the page loads. 我只想从控制器中的调用中触发contribEmailService.initForm()
函数,但是在页面加载后立即触发。
How do I set when the service function initForm()
is called? 调用服务函数initForm()
时如何设置?
Here is the corrected service code: 这是更正的服务代码:
'use strict';
angular.module('forbesArticleApp').service('contribEmailService', [
'$injector', '$route', 'ArticleAppState', 'fbsUserFormFactory', 'fbsUserDataService',
function($injector, $route, ArticleAppState, fbsUserFormFactory, fbsUserDataService) {
return {
initForm: function() {
console.log("Hello world!");
}
};
]);
The service function is a factory that will in turn return the actual service. 服务功能是一家工厂,它将依次返回实际服务。 So it will run the first time it is requested as a dependency. 因此它将在第一次作为依赖项被请求时运行。 The way you had it written, in fact, contribEmailService
would have been undefined
within your function, because your factory didn't actually return anything. 实际上,您在函数中尚未undefined
contribEmailService
编写方式,因为工厂实际上并未返回任何内容。
Hope this helps! 希望这可以帮助!
controller:-
blogcontroller is controller name
app.controller('blogController', function($scope, $compile, $http, blogAuth, AppInfo, $location,$element){
$scope.blog_abuse = function(blog_id)
{
blogAuth.BlogAbuse(blog_id).then(function(response)
{
$scope.DetailblogList.is_abused = response.records.is_abused;
},function(error){
});
}
});
service:-
app.factory('AppInfo', function(){
return {
serviceURL:site_url
};
});
app.service('blogAuth', function($http, $rootScope, $q, AppInfo){
this.BlogAbuse = function(blog_id){
var deferred = $q.defer();
var pageObj ={"blog_id":blog_id};
$http.post(AppInfo.serviceURL+'blog/blog_abuse',pageObj).success(function(data){
deferred.resolve(data);
}).error(function(msg, code) {
console.log('error', code, msg );
});
return deferred.promise;
}
});
