I would like to reflect post request status by showing/hiding success/error html element with the error description. I have following controller with use of $http service:
$ctrl.addCorporateTransport = function() {
var postStatusBar = angular.element('postStatusBar');
$http.post('/post_corporate_transport', $ctrl.corporateTransport)
.success(function () {
// throw success alert
})
.error(function (error) {
// throw error alert
});
};
I'm looking for having possibility to throw <div class="alert"><p>my error here</p> if I hit error callback.
I tried this:
var statusBar = angular.element('postStatusBar');
//...
.success(function () {
statusBar.setClass("alert-success")
})
.error(function (error) {
statusBar.setClass("alert-danger");
statusBar.setParameter("text", error);
});
But it doesn't work obviously and looks like anti-pattern. What is the best solution for doing the thing?
If the alert component is outside controller scope than you need make the alert a directive and use broadcast to notify and update properties like visibility.
else you can bind properties from controller like:
<div ng-controller="AwesomeController as AwesomeCtrl">
<div class="alert" ng-show="AwesomeCtrl.show.error">....
<div class="alert" ng-show="AwesomeCtrl.show.success">....
<div class="alert" ng-class="{ 'succes' : AwesomeCtrl.show.success }">....
enter code here
angular
.module('app')
.controller('AwesomeController', controller);
controller.$inject = ['$http'];
function controller($http) {
var vm = this;
vm.corporateTransport = {};
vm.show = {
error = false;
success = false;
}
vm.oneCoolMethod = addCorporateTransport;
// test
addCorporateTransport();
function addCorporateTransport() {
$http.post('/post_corporate_transport', vm.corporateTransport)
.success(onTransportSuccess)
.error(onTransportError);
};
function onTransportSuccess(result) {
toggleAlert('success');
}
function onTransportError(result) {
toggleAlert('error');
}
function toggleAlert(level) {
angular.forEach(vm.show, function(value, key) {
vm.show[key] = false;
});
vm.show[level] = true;
}
at the first you must using $scope.statusBar
and also addClass except setClass
I'm using this override to get the content of a js file as a string.
Content of the variable where the js file is loaded into:
<html>
<body>
//META{"name":"testPlugin"}*//
function testPlugin() {
var settings = {
testSettingBool : true,
testSettingInt : 123,
testSettingStr : "Test String",
}
}
testPlugin.prototype.getName = function() { return "Test"; };
testPlugin.prototype.getDescription = function() { return "Test Description"; };
testPlugin.prototype.getVersion = function() { return "1.0"; };
</body>
</html>
Now i only want to eval a special function in that string like
testPlugin.prototype.getVersion();
Thanks for any help :)
I am following this article on Social Logins with AngularJS and ASP.Net WebAPI (which is quite good):
ASP.NET Web API 2 external logins with Facebook and Google in AngularJS app
Pretty much, the code works fine when you are running the social login through a desktop browser (i.e. Chrome, FF, IE, Edge). The social login opens in a new window (not tab) and you are able to use either your Google or Facebook account and once your are logged in through any of them, you are redirected to the callback page (authComplete.html), and the callback page has a JS file defined (authComplete.js) that would close the window and execute a command on the parent window.
the angularJS controller which calls the external login url and opens a popup window (not tab) on desktop browsers:
loginController.js
'use strict';
app.controller('loginController', ['$scope', '$location', 'authService', 'ngAuthSettings', function ($scope, $location, authService, ngAuthSettings) {
$scope.loginData = {
userName: "",
password: "",
useRefreshTokens: false
};
$scope.message = "";
$scope.login = function () {
authService.login($scope.loginData).then(function (response) {
$location.path('/orders');
},
function (err) {
$scope.message = err.error_description;
});
};
$scope.authExternalProvider = function (provider) {
var redirectUri = location.protocol + '//' + location.host + '/authcomplete.html';
var externalProviderUrl = ngAuthSettings.apiServiceBaseUri + "api/Account/ExternalLogin?provider=" + provider
+ "&response_type=token&client_id=" + ngAuthSettings.clientId
+ "&redirect_uri=" + redirectUri;
window.$windowScope = $scope;
var oauthWindow = window.open(externalProviderUrl, "Authenticate Account", "location=0,status=0,width=600,height=750");
};
$scope.authCompletedCB = function (fragment) {
$scope.$apply(function () {
if (fragment.haslocalaccount == 'False') {
authService.logOut();
authService.externalAuthData = {
provider: fragment.provider,
userName: fragment.external_user_name,
externalAccessToken: fragment.external_access_token
};
$location.path('/associate');
}
else {
//Obtain access token and redirect to orders
var externalData = { provider: fragment.provider, externalAccessToken: fragment.external_access_token };
authService.obtainAccessToken(externalData).then(function (response) {
$location.path('/orders');
},
function (err) {
$scope.message = err.error_description;
});
}
});
}
}]);
authComplete.html
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

</html>
authComplete.js
window.common = (function () {
var common = {};
common.getFragment = function getFragment() {
if (window.location.hash.indexOf("#") === 0) {
return parseQueryString(window.location.hash.substr(1));
} else {
return {};
}
};
function parseQueryString(queryString) {
var data = {},
pairs, pair, separatorIndex, escapedKey, escapedValue, key, value;
if (queryString === null) {
return data;
}
pairs = queryString.split("&");
for (var i = 0; i < pairs.length; i++) {
pair = pairs[i];
separatorIndex = pair.indexOf("=");
if (separatorIndex === -1) {
escapedKey = pair;
escapedValue = null;
} else {
escapedKey = pair.substr(0, separatorIndex);
escapedValue = pair.substr(separatorIndex + 1);
}
key = decodeURIComponent(escapedKey);
value = decodeURIComponent(escapedValue);
data[key] = value;
}
return data;
}
return common;
})();
var fragment = common.getFragment();
window.location.hash = fragment.state || '';
window.opener.$windowScope.authCompletedCB(fragment);
window.close();
The issue I am having is that when I run the application on a mobile device (Safari, Chrome for Mobile), the social login window opens in a new tab and the JS function which was intended to pass back the fragment to the main application window does not execute nad the new tab does not close.
You can actually try this behavior on both a desktop and mobile browser through the application:
http://ngauthenticationapi.azurewebsites.net/
What I have tried so far in this context is in the login controller, I modified the function so that the external login url opens in the same window:
$scope.authExternalProvider = function (provider) {
var redirectUri = location.protocol + '//' + location.host + '/authcomplete.html';
var externalProviderUrl = ngAuthSettings.apiServiceBaseUri + "api/Account/ExternalLogin?provider=" + provider
+ "&response_type=token&client_id=" + ngAuthSettings.clientId
+ "&redirect_uri=" + redirectUri;
window.location = externalProviderUrl;
};
And modified the authComplete.js common.getFragment function to return to the login page, by appending the access token provided by the social login as query string:
common.getFragment = function getFragment() {
if (window.location.hash.indexOf("#") === 0) {
var hash = window.location.hash.substr(1);
var redirectUrl = location.protocol + '//' + location.host + '/#/login?ext=' + hash;
window.location = redirectUrl;
} else {
return {};
}
};
And in the login controller, I added a function to parse the querystring and try to call the $scope.authCompletedCB(fragment) function like:
var vm = this;
var fragment = null;
vm.testFn = function (fragment) {
$scope.$apply(function () {
if (fragment.haslocalaccount == 'False') {
authenticationService.logOut();
authenticationService.externalAuthData = {
provider: fragment.provider,
userName: fragment.external_user_name,
externalAccessToken: fragment.external_access_token
};
$location.path('/associate');
}
else {
//Obtain access token and redirect to orders
var externalData = { provider: fragment.provider, externalAccessToken: fragment.external_access_token };
authenticationService.obtainAccessToken(externalData).then(function (response) {
$location.path('/home');
},
function (err) {
$scope.message = err.error_description;
});
}
});
}
init();
function parseQueryString(queryString) {
var data = {},
pairs, pair, separatorIndex, escapedKey, escapedValue, key, value;
if (queryString === null) {
return data;
}
pairs = queryString.split("&");
for (var i = 0; i < pairs.length; i++) {
pair = pairs[i];
separatorIndex = pair.indexOf("=");
if (separatorIndex === -1) {
escapedKey = pair;
escapedValue = null;
} else {
escapedKey = pair.substr(0, separatorIndex);
escapedValue = pair.substr(separatorIndex + 1);
}
key = decodeURIComponent(escapedKey);
value = decodeURIComponent(escapedValue);
data[key] = value;
}
return data;
}
function init() {
var idx = window.location.hash.indexOf("ext=");
if (window.location.hash.indexOf("#") === 0) {
fragment = parseQueryString(window.location.hash.substr(idx));
vm.testFn(fragment);
}
}
But obviously this is giving me an error related to angular (which I have no clue at the moment):
https://docs.angularjs.org/error/$rootScope/inprog?p0=$digest
So, pretty much it is a dead end for me at this stage.
Any ideas or input would be highly appreciated.
Gracias!
Update: I managed to resolve the Angular error about the rootscope being thrown, but sadly, resolving that does not fix the main issue. If I tried to open the social login on the same browser tab where my application is, Google can login and return to the application and pass the tokens required. It is a different story for Facebook, where in the Developer's tools console, there is a warning that seems to stop Facebook from displaying the login page.
Pretty much, the original method with which a new window (or tab) is opened is the way forward but fixing the same for mobile browser seems to be getting more challenging.
On desktop, when the auth window pops up (not tab) it has the opener property set to the window which opened this pop up window, on mobile, as you said, its not a pop up window but a new tab. when a new tab is opened in the browser, the opener property is null so actually you have an exception here:
window.opener.$windowScope.authCompletedCB
because you can't refer the $windowScope property of the null value (window.opener) so every line of code after this one wont be executed - thats why the window isn't closed on mobile.
A Solution
In your authComplete.js file, instead of trying to call
window.opener.$windowScope.authCompletedCB and pass the fragment of the user, save the fragment in the localStorage or in a cookie (after all the page at authComplete.html is in the same origin as your application) using JSON.stringify() and just close the window using window.close().
In the loginController.js, make an $interval for something like 100ms to check for a value in the localStorage or in a cookie (don't forget to clear the interval when the $scope is $destroy), if afragment exist you can parse its value using JSON.parse from the storage, remove it from the storage and call $scope.authCompletedCB with the parsed value.
UPDATE - Added code samples
authComplete.js
...
var fragment = common.getFragment();
// window.location.hash = fragment.state || '';
// window.opener.$windowScope.authCompletedCB(fragment);
localStorage.setItem("auth_fragment", JSON.stringify(fragment))
window.close();
loginController.js
app.controller('loginController', ['$scope', '$interval', '$location', 'authService', 'ngAuthSettings',
function ($scope, $interval, $location, authService, ngAuthSettings) {
...
// check for fragment every 100ms
var _interval = $interval(_checkForFragment, 100);
function _checkForFragment() {
var fragment = localStorage.getItem("auth_fragment");
if(fragment && (fragment = JSON.parse(fragment))) {
// clear the fragment from the storage
localStorage.removeItem("auth_fragment");
// continue as usual
$scope.authCompletedCB(fragment);
// stop looking for fragmet
_clearInterval();
}
}
function _clearInterval() {
$interval.cancel(_interval);
}
$scope.$on("$destroy", function() {
// clear the interval when $scope is destroyed
_clearInterval();
});
}]);
I have a URL route that has a parameter whose value is not known ahead of time when the page is loaded. For example:
/read/book/page/:page
But when the user is selection screen they get to type in which page number they want to start on then click submit. Is it possible to catch this form submission and place it in the URL? Normally there is a question mark (?) right because its a GET request. But Backbone how can backbone catch that?
Demo:
http://jsfiddle.net/vpetrychuk/PT2tU/
JS:
var Model = Backbone.Model.extend({
url : function () {
return 'http://fiddle.jshell.net/echo/json?page=' + this.get('page');
},
// remove it
parse : function (response) {
response || (response = {});
response.justToTriggerChangeEvent = Math.random();
return response;
},
getPageContent : function () {
return 'Here should be page a content for page #' + this.get('page');
}
});
var View = Backbone.View.extend({
el : '[data-page]',
events : {
'submit' : 'submit'
},
initialize : function () {
this.listenTo(this.model, 'change', this.showPage);
},
showPage : function () {
this.$('[data-page-content]').html(this.model.getPageContent());
},
submit : function (e) {
e.preventDefault();
var page = this.$('[data-page-num]').val();
if (page) {
app.navigate('read/book/page/' + page, true);
}
}
});
var Router = Backbone.Router.extend({
routes : {
'read/book/page/:page' : 'page'
},
initialize : function (options) {
this.bookModel = options.bookModel;
},
page : function (page) {
this.bookModel.set('page', page);
this.bookModel.fetch();
}
});
var model = new Model();
var view = new View({model:model});
var app = new Router({bookModel:model});
Backbone.history.start();
HTML:
<div data-page>
<form>
<label><input type="text" data-page-num /></label>
<button type="submit">Submit</button>
</form>
<div data-page-content></div>
</div>
I'm using the following code to get google contacts name and phone number. Authorization page itself is not coming properly it shows error as "The page you requested is invalid". :( pls help me to solve this...
`
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("gdata", "1.x");
var contactsService;
function setupContactsService()
{
contactsService = new google.gdata.contacts.ContactsService('exampleCo-exampleApp-1.0');
}
function logMeIn() {
var scope = 'https://www.google.com/m8/feeds';
var token = google.accounts.user.login(scope);
}
function initFunc() {
setupContactsService();
logMeIn();
getMyContacts();
}
function checkLoggedIn(){
scope = "https://www.google.com/m8/feeds";
var token = google.accounts.user.checkLogin(scope);
if(token != "")
return true;
else
return false;
}
function getMyContacts() {
var contactsFeedUri = 'https://www.google.com/m8/feeds/contacts/default/full';
var query = new google.gdata.contacts.ContactQuery(contactsFeedUri);
//We load all results by default//
query.setMaxResults(10);
contactsService.getContactFeed(query, handleContactsFeed, ContactsServiceInitError);
}
//Gets the contacts feed passed as parameter//
var handleContactsFeed = function(result) {
//All contact entries//
entries = result.feed.entry;
for (var i = 0; i < entries.length; i++) {
var contactEntry = entries[i];
var telNumbers = contactEntry.getPhoneNumbers();
var title = contactEntry.getTitle().getText();
}
}
</script>
<body>
<input type="submit" value="Login to Google" id="glogin" onclick="initFunc();">
</body>`
Thanks
It looks like you are trying to use the Google Contacts 1.X API. That's been deprecated. Look at the JavaScript examples for the Google 3.X API and see if that helps.
You can try this example
var config = {
'client_id': 'Client ID',
'scope': 'https://www.google.com/m8/feeds'
};
inviteContacts = function() {
gapi.auth.authorize($scope.config, function() {
fetch(gapi.auth.getToken());
});
}
function fetch(token) {
$.get("https://www.google.com/m8/feeds/contacts/default/full?access_token=" + token.access_token + "&alt=json", function(response) {
console.log(response);
//console.log(response.data.feed.entry);
});
}
Don't forget to add <script src="https://apis.google.com/js/client.js"></script> into your html file. Good Luck!
