How to force start controller when click on just opened link - angularjs

When i try to go to just opened link, $routeProvider doestn't start the controller again.
Example:
in html code I have some links(dynamically), for example url1, url2, url3.
when I click on url2, $routeProvider starts the controller.
after some time, If I click again on this link - controller doesn't get started (only works for different links)
How to force start the controller, when clicked on just opened link?
Or run init code for all links on click(but after this go to target link)?

Use $route.reload();
From the Docs:
$route.reload();
Causes $route service to reload the current route even if $location hasn't changed.
As a result of that, ngView creates new scope and reinstantiates the controller.
-- AngularJS $route API Reference - reload

Can you post your example? Based on how you have configured your $stateProvider might be the problem.

How to replace url part before #

My angularJs App URL is opened via another application. URL to open my app looks like,
http://localhost:21770/App/IAnalytics?FromApp=abc#/PBIDefault
where FromApp is the parameter which indicates the source app from where angularjs app is called.
I would like to remove the FromApp=abc part from URL once my home page controller starts running.
I need to make sure by URL looks like,
http://localhost:21770/App/IAnalytics?#/PBIDefault
How can I achieve the same using $routeProvider or $location ?
You look for params once your home page controller starts .
If you find a parameter, you change the state of your app to the home page of the app (But without parameters this time). you can use $routeProvider, $location or $stateProvider for that.
Like this:
if ($location.search().FromApp){
$state.go('app.home',null, { reload: true }); // 'app.home' is name of your home page state.
}

AngularJS Routing not working when url typed

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.

Angular Routing Issue (Default View)

I am having an angular application, I want when first navigating to the homepage of my application, to get a specific view called: Search.html, I want anytime I open this home page to render this view, how do we do this in Angular? I have checked the online documentation and it's doing so by having Urls that redirect to another page, for my case, I don't have Urls, I have a landing page where I want to get a specific view when it's opened.
Here's a link to plunker that shows my issue.
I would imagine the issue is because you need to link the dependency script angular-route.js in your head, and also define your app with ng-app. Also, putting your controller and module code in separate anonymous functions prohibits the controller from seeing the module variable.
Check out this fork of your plunkr for how to get it to work.
you can use $routeProvider like this
angular
.module('myApp', ['ngRoute'])
.config(['$routeProvider', function($routeProvider) {
$routeProvider.otherwise({redirectTo: '/search'});
}]);

AngularJS and PhoneGap: $location.path causes subsequent tempateUrl lookup to fail

I'm having trouble getting path lookup to work with a AngularJS v1.2.0 and PhoneGap/Cordova Android application. I've come pretty far with html5mode(true) by setting <base href="."/> in index.html and then changing $routeProvider.when('/') to $routeProvider.when('/android_asset/www/index.html'). After that I am able to get redirectTo('login') to reach $routeProvider.when('/login') and there render templateUrl: 'static/partials/login.html' as expected.
The problem I have is that if I instead try to redirect to the login page from my Javascript code with $location.path('/login');, the route is found but templateUrl loading fails with an insecurl exception.
I've tried whitelisting access to file:// by using the new angular-sanitize module, but that does not help.
How can I make $location.path() do the same things as redirectTo so that the partial is loaded? Or is there some other way to solve this problem?
UPDATE: I got a bit forward by adding a call to replace() after the path function, e.g.:
$location.path('/login').replace();
but that seems like a hack, and it still causes the templateUrl in the otherwise route to fail with the same exception.
Any ideas on what might be wrong? Is it that html5mode(true) just does not work at this moment with Phonegap and the only way to fix this is to set it to false and add hashtags to every path (like is done in the angular phonegap seed project)?
For future reference, this is how I managed to solve the problem:
AngularJS currently does not seem to support html5mode(true) inside a Cordova application because of the insecurl problem I reported. What I had to do is add
var h5m = (typeof html5Mode !== 'undefined') ? html5Mode : true;
$locationProvider.html5Mode(h5m);
which gives me the possibility to explicitly set html5Mode in the PhoneGap index.html with a global variable:
<script>
var html5Mode = false;
</script>
So now $location.path('/login') as well as redirectTo: 'login' works, but links in html files, don't. To get those working in PhoneGap, with html5Mode disabled, I had to add #/ in front of every link, e.g. login.
That makes PhoneGap work, but breaks the web page which uses History API with html5Mode(true). The last piece of the puzzle was to add <base href="/"/> to the web page's index.html (and leave it out of the index.html of the PhoneGap project.) So now even though I have a link that says #/login in the web page, I get to the url http://example.com/login and don't see any hashes in the address bar.
**
So in the end I have History API working in my web page and History API disabled in the PhoneGap project (where there really is no need for History API as there is no address bar). The only downside is the extra #/ I have to put in each template html file, but that is a minor annoyance compared to the ability to use all of the same html and javascript files for both web and mobile.
I had this same problem as well. I managed to fix it by skipping the leading slash in the route config:
$routeProvider
// route for the foo page
.when('/foo', {
templateUrl: 'foo.html', //previously: '/foo.html'
controller: 'fooController'
}) //etc.

AngularJS routing with Mongoose webserver

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.
