Angular ui-router not loading external content on state change - javascript

I have started building a website using Angular, and have started to use ui-router along with ngAnimation for some sick animations! All was going well until I started adding external resources such as Facebook's Page Widget (https://developers.facebook.com/docs/plugins/page-plugin) and Google Maps API for some custom map styles.
The Issue
I have the Facebook widget on the home page, and it loads fine when you first access the URL as can be seen below (Have to block the name of client, totally not just bad design...):
Once I click on another page to load it in (using ui-view to dynamically bring in a view), for example contact view and go back to the home page (where the code is to display the widget), the widget will no longer load but will load the basic header tag that Facebook provide as can be seen below:
This also happens on the contact page when loading in Google Maps API. If I click on the contact page, there will just be a large white area on where the map should be, but if you had to actually refresh the page the map will load.
I am assuming that the issue is that the website is not able to send a request to either Facebook or Google when a view is loaded in, but can only happen when the page is actually refreshed or a new page load.
My Code
Okay so I'll explain the basics of how my application works along with code. I am rather new with Angular so if I have terrible code, please let me know.
Structure
This is a screen shot of my web apps structure. The main template file is index.html, and any view are within the views directory, which are loaded in using ui-router.
Main Angular applications code (app.js)
var app = angular.module('bmApp', ['ngAnimate', 'ui.router', 'ui.bootstrap'])
.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('header', {
templateUrl: './assets/views/template.html',
})
.state('header.home', {
url: '/',
templateUrl: './assets/views/home.html',
controller: "HomeController"
})
.state('header.about', {
url: '/about',
templateUrl: './assets/views/about.html',
controller: "AboutController"
})
.state('header.work', {
url: '/work',
templateUrl: './assets/views/work.html',
controller: "WorkController"
})
.state('header.services', {
url: '/services',
templateUrl: './assets/views/services.html',
controller: "ServicesController"
})
.state('header.contact', {
url: '/contact',
templateUrl: './assets/views/contact.html',
controller: "ContactController"
});
$urlRouterProvider.otherwise('/'); //if no views are matched, just redirect back to home page.
})
I am using nested views to keep the header of the website static (not changing) and then loading in views under the header, with ngAnimate to make it look cool.
In my main template, index.html, I have a simple <div ui-view></div> to load in the view that is requested. I also have the required script to request Facebook's API just after the . My controllers do not actually currently have anything in them. I did have some vanilla JavaScript in some, but do not currently need it anymore. I also tried to wrap the code provided by Facebook in a function, and call it within the controller for the specific view but that just had the same results of having it within the body on the template (index.html) page.
Pulling my hair out at this, can't seem to find a solution. I hope I have explained my issue without missing out on anything. I appreciate any help you could give, would be so awesome.
Edit: I should have probably mentioned that my main template is index.html, I then inject the view in to /views/template.html AND THEN inject it into index.html. Not too sure if this is best practice, but felt like it would work well (I don't think that is the issue).

I will give you only half of an answer, but maybe it will point you to right direction. I also struggled with Google API in SPA application once. I had the same issue - after entering the contact page, a white box appeared instead of map. The solution turned out to be simple - I just needed to force map reload, when I entered contact sheet. This function was attached as onclick event to contact page link:
function reloadGoogleMap() {
if (counter == 0) {
document.getElementById('google-map').src += '';
counter++;
}
}
I used the counter to make sure it happens only once - you won't need it probably. With Angular, you might need to make sure the reload happens after element is rendered. Maybe a simple directive would work, however I didn't test that:
angular.module('your_directives_module')
.directive('mapLoaded', [mapLoadedDirective]);
function mapLoadedDirective() {
return {
restrict: 'A',
link: function (scope, elem, attrs) {
elem.on('load', function (event) {
// Force reload
elem.src += '';
});
}
};
}
It could be used like:
<!-- Div/iframe with google map -->
<div map-loaded></div>
Maybe Facebook API also has some simple way which you could use to force widget reload when the partial view is loaded, however I've never tried to use that with Angular.

Don't you have to wrap it in a $rootScope.$apply function in order to update your view?
$rootScope.$apply(function () {
// some code
});

How to localize / internationalize baSidebar of Blur Admin

i'am trying to localize the baSidebar Navigation of Akveos BlurAdmin.
In the ba-sidebar.html i'am using the translate-filter like {{ ::item.title | translate }}
and the state ist set like:
function routeConfig($stateProvider, dashboardProvider) {
$stateProvider
.state('stateName', {
url: '/stateName',
templateUrl: 'app/pages/[...],
controller: 'stateNameCtrl',
title: 'TITLES.STATENAME',
sidebarMeta: {
order: 200,
},
}) [...]
Angular gets the translation of TITLES.STATENAME from a .json-file. The title of the contentTop is perfectly changing by changing the active language. (i'm using $state.reload(); by ng-click). But the sidebar wont reload. The title still be in the same language which was active while loading the page. If i log off and log in again, the new language is active and shown correctly.
Is there a way to reload the ba-sidebar.html within an ng-click-event like i did with $state.reload()? (i dont want to reload the entire page, because then the site reloads all defaults including the default language)
I solved the problem by saving the language in cookies and reloading the entire page. on load it gets the language from the cookies. if this languagekey isn't set, it loads the default language.
For people who get stuck in the same issue: here is a documentation of using cookies in javascript: http://www.w3schools.com/js/js_cookies.asp

Ionic: $state.go() changes URL but not the view

I'm totally new to Ionic and JavaScript and I'm having a few problems when changing views in my project.
I've created the project using the tabs starter, and everything works when moving withing the default tabs and even when adding new ones. At certain parts of the code, I need to move to a tab view so I'm using the $state.go() function and it works fine. However, I've added a new view with its template, controller, and state and I need to load it when clicking a button. So I use $state.go() again, but the URL in the explorer changes but not the view, it stays in the previous one. It doesn't work either when I type the URL in the browser, so maybe the problem is in the state definition, but I'm pretty sure it is ok.
State
.state('tab.file_explorer', {
url: '/file_explorer',
views: {
'tab-file_explorer': {
templateUrl: 'templates/tab-file_explorer.html',
controller: 'file_explorerCtrl'
}
}
})
Controller
It is in the controller of another view where the button is located (the button works fine, I've tested it). The file_explorerCtrl controller is empty at the moment.
.controller('load_csvCtrl', function($scope, $state) {
$scope.loadCsv = function(){
$state.go('tab.file_explorer');
}
}
This redirects to the URL http://localhost:8100/#/tab/file_explorer, with no console output or 404 errors. I've also tried using $location.path() and $window.location.assign() but it also fails to load the template.
I'd appreciate any help.
Can you check if your index.html has <ion-nav-view></ion-nav-view> tag
You're using named views. your <ion-nav-view> should match the name:
<ion-nav-view name="tab-file_explorer"></ion-nav-view>
Check the docs here:
https://github.com/angular-ui/ui-router/wiki/Multiple-Named-Views
Set cache-view="false" in View.
Example:
<ion-view cache-view="false">
<!-- View Content goes here -->
</ion-view>

AngularJS execute code when changing pages that use same controller

I have a PhoneGap app, that has multiple html pages.
I use one controller, called AppController, that loads the data for the startup screen and default pages.
I added a new page to the navigation bar, which, when clicked & opened should load up data from the server with a php call, so it should only make a php call, when the page is shown.
This page uses the same controller as the rest of the app.
I am really new to AngularJS, so I might've programmed it in a bad way, but the rest of the data for the home page is loaded in the appController like this
myApp.controller('AppController', function ($scope, $timeout, sharedProperties) {
$scope.items= {};
$scope.items[item1] = {....} //LOADING UP the items collection
}
How can I hook up an "onload" event or something, that would only fire when the page is shown?
There are so many ways you could do that, one of them:
// inside your controller
angular.element(document).ready(function () {
// your code
});
another one:
<div ng-controller="myCtrl" ng-init="someinitfunc()"></div>
How about using ng-init() directive on your next page ?

$state.go() doesn't load controller in ionic application

Using the following code, when a page with id=0 loads first time there is no problem with controller. But when again the same page loads with same id=0 again, it does not loads controller.
$state.go('tab.dash', {
id: $rootScope.products[CONSTANTS.i].id
}, {
reload: true
});
How does it happen? Please suggest me a solution.
I encountered a similar problem where I needed stats to recalculate every time a tab was visited.
You need to disable view caching. You can do so in the route setup. For example:
.state('tab.stats', {
url: '/stats',
views: {
'tab-stats': {
templateUrl: 'templates/tab-stats.html',
controller: 'StatsCtrl'
}
},
cache: false
})
well, When you cache the view (by default it is true) controller is loaded only at first time and on subsequent navigation it will attach and detach the scope. Cacheing helping with the performance of single page applications. If you dont want to disable the caching then you use the ionic view events like (enter, leave,loaded and so on).
$scope.$on('$ionicView.enter', function () {
// ur stuff in here....
});

angularjs - refresh when clicked on link with actual url

I use routeProvider to define controlers and templates for my urls.
When I click on the link, which has the same url as is the actual location, nothing happens. I would like the reload() method to be called if a user clicks on such a link even if the location hasn't changed. In other words, if I set the location to the same value, I would like it to behave the same as if I would set it to different value.
Is there a way to configure routeProvider or locationProvider to do it automatically? Or what is the right approach to do this? This is stadard behaviour in round trip applications, but how to do it in angularjs?
I've asked it on google groups as well.
UPDATE:
This question is getting lots of views, so I will try to explain how I solved my problem.
I created a custom directive for linking in my app as Renan Tomal Fernandes suggested in comments.
angular.module('core.directives').directive('diHref', ['$location', '$route',
function($location, $route) {
return function(scope, element, attrs) {
scope.$watch('diHref', function() {
if(attrs.diHref) {
element.attr('href', attrs.diHref);
element.bind('click', function(event) {
scope.$apply(function(){
if($location.path() == attrs.diHref) $route.reload();
});
});
}
});
}
}]);
The directive is then used for all links in my app I want to have this functionality.
<a di-href="/home/">Home</a>
What this directive does is that it sets the href attribute for you based on di-href attribute so angular can handle it like always and you can see the url when you hover over the link. Furthermore when user clicks on it and the link's path is the same as the current path it reloads the route.
Add a / (slash) to the defined url in the route configuration
I met a similar problem today, I have a link in my web page and when I click it, I want the ng-view reload each time, so that I can refresh data from server. But if the url location doesn't change, angular doesn't reload the ng-view.
Finally, i found a solution to this problem. In my web page, I set the link href to:
test
But in the route config, I set:
$routeProvider.when('/test/', {
controller: MyController,
templateUrl:'/static/test.html'
});
The different is the last slash in url. When I click href="#/test" for the first time, angular redirect the url to #/test/, and load ng-view. when i click it second time, because the current url is #/test/, it's not equal to the url in the link (href="#/test") I clicked, so Angular triggers the location change method and reloads the ng-view, in addition Angular redirects the url to #/test/ again. next time i click the url, angular does the same thing again. Which is exactly what I wanted.
Hope this was useful for you.
You can add a _target='_self' on the link to forces the page to reload.
e.g.
{{customer.Name}}
Tested with version 1.0.5 and 1.2.15 on IE and Firefox.
Here's more information from AngularJS site :
Html link rewriting
When you use HTML5 history API mode, you will need different links in different browsers, but all you have to do is specify regular URL links, such as:
link
When a user clicks on this link,
In a legacy browser, the URL changes to /index.html#!/some?foo=bar
In a modern browser, the URL changes to /some?foo=bar
In cases like the following, links are not rewritten; instead, the browser will perform a full page reload to the original link.
Links that contain target element
Example: link
Absolute links that go to a different domain
Example: link
Links starting with '/' that lead to a different base path when base is defined
Example: link
you should use $route.reload() to force the reload.
I don't know if is there a 'automatic' way to do this, but you can use ng-click on these links
For people who are using AngularUI Router. You can use something like this:
<a data-ui-sref="some.state" data-ui-sref-opts="{reload: true}">State</a>
Notice the reload option.
Found the answer here: https://stackoverflow.com/a/29384813/426840
From #Renan Tomal Fernandes answer. following is an example
HTML
<a href="#/something" my-refresh></a>
JS
angular.module("myModule",[]).
directive('myRefresh',function($location,$route){
return function(scope, element, attrs) {
element.bind('click',function(){
if(element[0] && element[0].href && element[0].href === $location.absUrl()){
$route.reload();
}
});
}
});
I think it's a simpler approach.
.directive ('a', function ($route, $location) {
var d = {};
d.restrict = 'E';
d.link = function (scope, elem, attrs) {
// has target
if ('target' in attrs) return;
// doesn't have href
if (!('href' in attrs)) return;
// href is not the current path
var href = elem [0].href;
elem.bind ('click', function () {
if (href !== $location.absUrl ()) return;
$route.reload ();
});
};
return d;
});
Assuming You want to make all basic <a> links (without target attribute) reload on click and You use relative links in the href attribute (e.g. /home instead of http://example.com/home) You don't have to add any special markup to your HTML (comes handy when updating a site with HTML already written).
In my case if the url is same, nothing worked including $route.reload(), $location.path(), $state.transitonTo() etc.
So my approach was Using Dummy Page as follows,
if( oldLocation === newLocation ) {
// nothing worked ------------
// window.location.reload(); it refresh the whole page
// $route.reload();
// $state.go($state.$current, null, { reload: true });
// $state.transitionTo($state.current, $stateParams, {reload:true, inherit: false, notify: false } );
// except this one
$location.path('/dummy');
$location.path($location.path());
$scope.$apply();
}
You need to make '/dummy' module somewhere, the module doesn't do anything, it only change url so that next $location.path() can be
applied. Don't miss $scope.$apply()
I ran into this issue a moment ago, except for it was the home page '/'. I wanted a simple solution with less code. I just took advantage of the .otherwise method in the $routProvider
So in the html link looks like:
Home
since there is no '/home' page specified in the routProvider it will redirect to '/' via the 'otherwise' method. page with this set up:
.otherwise({
redirectTo: '/'
});
Hope it helps someone
I tried Wittaya's solution above using directive approach. Somehow the directive keeps throwing error. I end up with this solution
HTML
Devices
Controller
$scope.stateGo = function (stateName) {
if ($state.$current.name === stateName) {
$state.reload();
} else {
$state.go(stateName);
}
}
Just tried adding this
$(window).on('popstate', function(event) {
//refresh server data
});
and it works fine
