More efficient method of passing $routeParams in the same view - angularjs

I have a button that's passing $routeParams
However this is too slow/clunky as it reloads the entire view by going to the same URL collections.html
Angular
$routeProvider.when('/products/:uId/:mId/productsList', {
templateUrl: '/views/collections.html',
controller: 'productsController'
});
HTML
<tr> ng-repeat="(key, product) in products">
<td>{{product.name}}</td>
<td>{{product.value}}</td></tr>
Is their a method of passing the $routeParams and loading a partial view
without reloading the entire view to speed things up a bit ?
e.g. ng-include instead of ng-href

Rendering the content of a page inside a div using ng-include based on the href of an element?

If I have two list items
<li></li>
<li></li>
and based on which is clicked, to use ng-include to render in a div on the current page?
<div ng-controller="main-panel" class="main-panel">
<ng-include src="'clickedElement'"></ng-include>
</div>
I am confused as to how to use routes to render an html inside a div, which is decided by which element you click?
main.config(function ($routeProvider, $locationProvider, $httpProvider) {
$routeProvider
.when('/', {
controller: 'side-menu'
})
.when('/signup', {
templateUrl : 'signup.html',
controller: 'main-panel'
});
$locationProvider.html5Mode(true);
});
HTML
<li ng-repeat="oucampus in secondaryLinks.oucampus">
<a ng-href='{{oucampus.href}}'> {{oucampus.title}} </a>
</li>
<div class="main-panel" ng-view></div>
CONTROLLER FUNCTION
oucampus: [
{title: "Requests", href:"signup.html"},
],
Plunker
If you are trying to render HTML content based on routes, you would want to use a routing service such as ngRoute or ui-router. ng-include isn't the best option for implementing routing within your angular application.
With ngRoute, you use a directive ng-view to have angular load html/controllers/etc based on route specified/configured in your applications config() method into some DOM element. This is triggered when you click on an <a> that has an ng-href with a corresponding path or programatically in something like a controller using the $location service path() method.
Route Configuration:
app.config(function($routeProvider) {
$routeProvider
.when('/foo', {
templateUrl: 'foo.html',
controller: 'FooController'
})
.when('/bar', {
templateUrl: 'bar.html',
controller: 'BarController'
});
});
HTML:
<ul>
<li><a ng-href="#/foo">foo</a></li>
<li><a ng-href="#/bar">bar</a></li>
</ul>
<div ng-view></div>
Here is a plunker demonstrating the functionality of basic routing including loading specific controllers and HTML templates based on a specific route.
ng-include
If you absolutely need to use ng-include, you can using a function executed via ng-click attached to $scope or controllerAs to update the src property of ng-include to load a template based on a click element. I've updated the plunker.
Hopefully this helps!

Use ui-view as the template for state inside ui-router instead of an external template

I have an app that is currently using the angular ui-router module dependency. The only aspect of the ui-router that I'm currently employing is the ability to apply/modify $stateParams to $scope and vice versa so the URL can change the way data is displayed in the controller to a user on arrival (i.e. url?param=something will filter the data by something).
I have the following in my app.config to set the state:
$stateProvider
.state('root', {
url: '/?param',
templateUrl: 'template.html',
controller: 'listController',
params: {
param: {
value: 'something',
squash: true
}
}
});
On my homepage, template.html successfully loads when the app is instantiated as such:
<div ng-app="myApp">
<div ui-view>
</div>
</div>
However, I have reached a roadblock and realize that calling the template from within templateUrl isn't going to work, as this app is being built inside another framework and therefore needs to be called from within the homepage itself to access its full capabilities.
Being a noob at AngualrJS, I was wondering if anyone can tell me what the best way is to accomplish this while still keeping the logic of $stateParams and other ui-router capabilities intact for the future.
For instance, could I just remove the templateUrl parameter from my state and call the controller directly inside the ui-view like this:
<div ng-app="myApp">
<div ui-view>
<div ng-controller="listController">
do something
</div>
</div>
</div>
I also looked into changing the entire logic from using ui-router to simply using the $location service but I'm wondering if there is a way to accomplish this without needing to over-do everything.

Angular Links in view not working

I am just beginning to experiment with AngularJS and have come across a problem.
My main page renders a <ng-view> element and I have set up the following routes:
(function () {
var routes = function ($routeProvider) {
$routeProvider.
when('/', {
templateUrl: 'Home/Overview',
controller: 'OverviewPageController'
})
.when('/Issue/:id', {
templateUrl: 'Home/Issue'
})
.otherwise({ redirectTo: '/' });
}
routes.$inject = ['$routeProvider'];
angular.module('PublicationSchedulerApp')
.config(routes);
}());
If I add a link tag outside of the <ng-view>:
<a ng-href="#/Issue/123">Issue</a>
The 'Issue' page is loaded into the view as expected.
In my case however, the Overview controller loads some data via an asynchronous Ajax call and then renders a table with a custom directive which, in turn, uses <ng-repeat>. If I create the same link within this directive/table:
<tr ng-repeat="issue in issues">
<td>
<a ng-href="#/issue/{{ issue.issueId }}">{{ issue.subject }}</a>
</td>
</tr>
The routing doesn't work. As you can see, I have played around with changing the link attribute from href to ng-href but this doesn't seem to make any difference. I am guessing that the asynchronous loading of the data is somehow breaking the routing, but I am not sure how to fix it. A couple of posts suggested that I reload the $route after the data load:
angular.module('PublicationSchedulerApp')
.run(['$route', function ($route) {
$route.reload();
}]);
but this didn't appear to make any difference either.
Any help would be much appreciated - thanks.
In Angular, routes are case sensitive. So make sure that your links match your route.
<tr ng-repeat="issue in issues">
<td>
<a ng-href="#/Issue/{{ issue.issueId }}">{{ issue.subject }}</a>
</td>
</tr>
You can also use ui-router, that way you will be able to create your links with state names rather than URLs (easier to maintain and less error-prone).

Changing attributes of enclosing containers based on current view

This is rather a conceptual than a strictly technical question.
I have the following index.html:
<div class="container"><div ng-view=""></div></div>
In my app.js, I have the following route configuration:
$routeProvider
.when('/questions', {
templateUrl: 'views/questions.html',
controller: 'QuestionsCtrl'
})
.when('/result', {
templateUrl: 'views/result.html',
controller: 'ResultCtrl'
})
.otherwise({
redirectTo: '/questions'
});
Which means that, based on the URL, different views are loaded in <div ng-view="">. Now, in order to have those views correctly rendered, I need to set style attributes on the enclosing <div class="container"> (I use Leaflet.js in one of those views and thus I need to temporarily set the width and height of the container to 100%, for a full screen map).
How would I do this best, i.e. "The Angular Way"? I looked at the $viewContentLoaded event of the ngView directive, but it doesn't seem to be the right thing as it seems to be only fired when the respective view is completely loaded and not at the initialization of the view (and thus the map, which needs a correctly styled container from beginning on). Should I use a controller that is defined on the body tag, for example? Or a service? I am completely clueless and want to make it right.
Use a controller that listens to $routeChangeSuccess on the $rootScope.
<body ng-app="X" ng-controller="app">
<div class="container" ng-class="containerClass">
<div ng-view=""></div>
</div>
</body>
angular.module('X').controller('app', function($rootScope, $route) {
$rootScope.$on('$routeChangeSuccess', function(){
$rootScope.containerClass = angular.lowercase(($route.current.controller || '').replace(/Ctrl$/, ''));
});
});

Angular ui-router reloading ng-include outside ui-view

Probably it's the entire layout wrong but here is my situation, I'm using a Meanjs.org stack with Angular ui-router.
I have a layout like this:
<div data-ng-include="'/modules/core/views/header.client.view.html'"></div>
<div id="page-content" class="clearfix" fit-height>
<div id="wrap" data-ui-view="" class="mainview-animation"></div>
</div>
Now I need to reload the controller inside the header.client.view.html when I change the $state.
For example when I'm in the sign-in page and I login I need to reload the header controller, but having this it's not possible because the ui-router change only the ui-view part with the relative template:
// this change only ui-view, doesn't care about the ng-include before
state('home', {
url: '/',
templateUrl: 'modules/core/views/home.client.view.html',
});
I found the possibility to add more ui-view to the state so I could add a ui-view2 for the header instead using the ng-include but this means having the ui-view2 on each state.
Any suggest?
You might not need to "reload the controller" every time the state changes, instead make your controller react to the state change on the fly and update its properties.
Check out the ui-router $stateChangeSuccess event.
First at all you need to listen #Matti Virkkunen
It's better to listen the state in your header's controller with "$stateChangeSuccess"
So you just have to declare a controller for your header. And inside your header controller add something like this.
$scope.$on('$stateChangeSuccess', function () {
// Do what you want for example check if the current state is home with $state.is('home');
});
Do not forget to declare your controller in your template
<div data-ng-controller="HeaderController" data-ng-include="'/modules/core/views/header.client.view.html'"></div>
<div id="page-content" class="clearfix" fit-height>
<div id="wrap" data-ui-view="" class="mainview-animation"></div>
</div>
