I'm trying to use AngularJS in a salesforce local hybrid android app, and while a simple test of the angular code works in firefox, when I run it in the Android emulator it loads for a fraction of a second and is replaced with a blank screen.
I've noticed that refreshing the page after routing ( going to [URL]/index.html#/ after the first page load ) ends up with an eternal 'ajax loading' spinner. I suspect this might be the root of my problem. My routing code looks like this:
var contactlistModule = angular.module("AugmentedContactList", ['ngRoute']);
contactlistModule.controller(ContactlistController);
contactlistModule.config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/', {
controller: 'ContactlistController',
templateUrl: 'viewparts/contactlistview.html'
}).when('/contact', {
controller: 'ContactController',
templateUrl: 'viewparts/contact.html'
}).otherwise({
redirectTo: '/'
});
}]);
Why does this refreshing error happen? Shouldn't going to index.html have the same effect as index.html#/ ?
I guess going to index.html without enabling html5Mode won't work as you expect.
You can enable it by injecting $locationProvider and adding this line to your config:
$locationProvider.html5Mode(true);
However, be aware that to enable html5 mode you will need to configure your server to return index.html (or whatever your main page is) on every URL request.

I just inherited an application where there are several ui-sref="portal.main.content" in the code.
What I'm confused about is, to navigate to this state, we need to enter /#/portal/main/content.
However it is rendered on the page without the #. So it will work when clicking on the page, however it won't work if I try to open into a new tab as that page doesn't exist. What am I missing here?
The problem comes from the fact that your application is served from a server environment that deals with urls as if they were real paths for real resources on the server file system. Therefore, when your are in a single page, it's not reloaded when you navigate to another state url, because ui-router handle this internally, consequently doesn't produce 404 or 403 errors, but when you load a page first time, it's required from the server and gives you 404 and 403 errors because the resource you're looking for doesn't exists or is forbidden.
What you have to do is to configure your server side environment to target the index.html page when your are not refering to a file (like css and js files), so all url will end up in the index.html page with an url to be handled by the ui-router. Each server side technology (Apache, IIS, node.js, etc) will have a different way to handle this, but mostly have a URL Rewrite module and similar ways to handle this.
Also, if it's not a problem by using the hash like url, you can disable html5Mode to prevent ui-router to do such thing. You can achieve this by injecting $locationProvider on your .config and disabling it like so: $locationProvider.html5Mode(false);
For example:
angular.module('myApp', ['ui.router'])
.config(function ($stateProvider, $locationProvider) {
$stateProvider
.state('home', {
url: '',
templateUrl: 'views/home.html',
controller: 'HomeCtrl'
})
.state('about', {
url: '/about',
templateUrl: 'views/about.html',
controller: 'aboutCtrl'
});
$locationProvider.html5Mode(false);
});
So, I'm pretty new to AngularJS and I'm trying to use AngularJs ngRoute in my application.
It all works smoothly when I start at the application homepage:
http://localhost:8080/appName/
And when I click on links from this point it works smoothly.
However, when I type a URL that I know exists/works, it gives me a 404 error. If I go to that link by using the application instead of the url it loads fine, even though it has the same url.
Eg. http://localhost:8080/appName/search
will give a 404, even though that is the same url that is the default redirect.
Indeed, the only url that will load by typing in the location is the base URL I mentioned above.
My app.js looks like this:
app.config( ['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider){
$routeProvider
.when("/search", {
templateUrl: "search.html",
controller: "SearchController"
})
.when("/results", {
templateUrl: "results.html",
controller: "ResultsController"
})
.when("/browse", {
templateUrl: "browse.html",
controller: "BrowseController"
})
.otherwise({redirectTo:"/search"});
//This gets rid of the # on the urls to the templates
$locationProvider.html5Mode(true);
}]);
I am hosting this on a glassfish4 server.
Is there something obvious I am missing/misunderstanding about how ngRoute works? Is there some setting that I am missing?
All help appreciated...
EDIT 1: As #Matthew Green below says, I need to configure the webserver to return the index.html for all pages below
http://localhost:8080/appName
I know I am being completely dense here, but where abouts is this configured? I am hosting the code in a MAVEN Jersey-Quickstart-Webapp.
When you use ngRoute, you are using javascript to handle routing to create a SPA. That means you need to hit a real page that loads your routing for your application to know what page to route to.
For example, your http://localhost:8080/appName/ should be routing to your index.html which would contain the javascript for your routing. With that page loaded it knows how to handle the links you have in your application. However, if you were to go directly to http://localhost:8080/appName/pageName you also need that to load index.html, as it is the one that loads your routing. Once your routing is loaded it should direct you to the correct page in your application. Without redirecting in place, http://localhost:8080/appName/pageName is not a real page and therefore correctly returns a 404.
Knowing this, the thing you have to figure out is what kind of server setup you have to configure the appropriate redirects for everything under http://localhost:8080/appName/ to go to your index.html page.
AngularJS - html5Mode - Cannot GET /login
So I have seen this post and my problem is very similar. I have used base tag to get my relative urls to work. And I have $locationProvider.html5Mode(true); in my application. Everything seems to work fine to keep /#/ urls out of the application, but when the user refreshes the browser it says page not found. The url it is going to is where my router should be pointing to:
$routeProvider
.when('/', {
templateUrl: 'views/coverPage.html',
controller: 'MainCtrl'
})
.when('/coverPage', {
templateUrl: 'views/coverPage.html',
controller: 'MainCtrl'
})
This is just an example of my router page. Again, this works when I link through a button, but when I load the url: http://www.someurl.com/somepath/coverPage it says page not found.
If it works fine, when navigating from a link but get a page not found when you refresh it appears to be a server side issue.
Be sure to acutally load the right angular app from the server at the specified url. You need a kind of wildcard url matching for the server side route. But without knowing more details of your application I can only guess.
When enabling the html5Mode in AngularJS via $locationProvider.html5Mode(true), navigation seems to be skewed when you land on a page deeper in the site.
for example:
http://www.site.com
when i navigate to the root, i can click all links in the site, Angular's $routeProvider will take over navigating through the site and loading the correct views.
http://www.site.com/news/archive
but when i navigate to this url (or hit refresh when I'm on a deeplink like the above one...) this navigation is not working as I expect it to.
first of all, our as the Documentation for $locationProvider.html5Mode specifies, we catch all urls on the server, similar to the otherwise route in angular, and return the same html as the root domain. But if I then check the $location object from within the run function of angular, it tells me that http://www.site.com is my host and that /archive is my path. the $routeProvider arrives in the .otherwise() clause, since i only have /news/archive as a valid route. and the app does weird stuff.
Maybe the rewriting on the server needs to be done differently, or I need to specify stuff in angular, but currently i'm clueless as to why angular see's the path without the /news segment included.
example main.js:
// Create an application module
var App = angular.module('App', []);
App.config(['$routeProvider', '$locationProvider', function AppConfig($routeProvider, $locationProvider) {
$routeProvider
.when(
'/', {
redirectTo: '/home'
})
.when('/home', {
templateUrl: 'templates/home.html'
})
.when('/login', {
templateUrl: 'templates/login.html'
})
.when('/news', {
templateUrl: 'templates/news.html'
})
.when('/news/archive', {
templateUrl: 'templates/newsarchive.html'
})
// removed other routes ... *snip
.otherwise({
redirectTo: '/home'
}
);
// enable html5Mode for pushstate ('#'-less URLs)
$locationProvider.html5Mode(true);
$locationProvider.hashPrefix('!');
}]);
// Initialize the application
App.run(['$location', function AppRun($location) {
debugger; // -->> here i debug the $location object to see what angular see's as URL
}]);
Edit
as per request, more details on the server side:
the server side is organised by the routing of zend framework, and it handles it's own routes (for serving data to the frontend on specific /api urls, and at the end, there is a catch-all route if no specific other route is bound, it serves the same html as the root-route.
so it basically serves the homepage html on that deeplinked route.
Update 2
after looking into the problem we noticed this routing works fine as it is, on Angular 1.0.7 stable, but shows the above described behaviour in the Angular 1.1.5 unstable.
I've checked the change-logs but haven't found anything useful so far, I guess we can either submit it as a bug, or unwanted behaviour linked to a certain change they did, or just wait and see if it get's fixed in the later to be released stable version.
Found out that there's no bug there.
Just add:
<base href="/" />
to your <head />.
This was the best solution I found after more time than I care to admit. Basically, add target="_self" to each link that you need to insure a page reload.
http://blog.panjiesw.com/posts/2013/09/angularjs-normal-links-with-html5mode/
This problem was due to the use of AngularJS 1.1.5 (which was unstable, and obviously had some bug or different implementation of the routing than it was in 1.0.7)
turning it back to 1.0.7 solved the problem instantly.
have tried the 1.2.0rc1 version, but have not finished testing as I had to rewrite some of the router functionality since they took it out of the core.
anyway, this problem is fixed when using AngularJS vs 1.0.7.
Configure AngularJS
$location / switching between html5 and hashbang mode / link rewriting
Configure your server:
https://github.com/angular-ui/ui-router/wiki/Frequently-Asked-Questions#wiki-how-to-configure-your-server-to-work-with-html5mode
My problem solved with these :
1- Add this to your head :
<base href="/" />
2- Use this in app.config
$locationProvider.html5Mode(true);
I'm testing a website locally on my machine. It uses AngularJS for routing and page changes, and I'm attempting to test the routes using the Mongoose webserver (extremely light).
My code is as follows:
app.config(['$locationProvider', '$routeProvider', function ($locationProvider, $routeProvider) {
$locationProvider.html5Mode(true);
$routeProvider.when('/who', {templateUrl: '/js/partials/who', controller: 'whoPage'});
$routeProvider.when('/what', {templateUrl: 'partials/what'});
$routeProvider.when('/want', {templateUrl: 'partials/want'});
$routeProvider.otherwise({ redirectTo: '/' });
}]);
(I haven't set up controllers for some of the other pages yet. I've been testing the "who" page.)
I'm running the page from localhost:8080. In my application, when I click a link to change the location, nothing happens. The URL changes to "localhost:8080/who", but I get no messages from console, and I get no changes on my page. However, if I then refresh that URL, I get a 404 error.
I don't have any server-side routing set up. Is this a necessity for Angular apps? Is there something wrong with the code I've written, or should I try a different test webserver?
$locationProvider.html5Mode(true);
will make angular use "push state" from the HTML5 History API.
This means that you'll see the url change in the location bar, but that won't cause the browser to actually reload your page. When you reload the page, the browser will now fetch that url from the webserver, which doesn't have it.
A common trick is to use URL rewrites to map any url back to index.html. You should take care of not remapping the urls that point to static files such as your javascript and css resources. That's usually easy because it's a good practice to group all your css and js files in some directory instead of scattering them in the top level dir.
