I have site with tabs that contain some data. The $scope is changed to vm in the controller. I want to execute a function every time the tab is changed.I have tried ng-change, but that only lead to errors in angular.
So I did read some postings here and found the ngModel method. But this does not work either. I always get a Error: String contains an invalid character from angular.min.js .
<b2b-tabset tab-id-selected="vm.activeTabsId" ng-if="vm.selectedUserID" [ngModel]="vm.activeTabsId" (ngModelChange)="vm.changeTab()" >
<b2b-tab ng-repeat="tab in vm.gTabs" tab-item="tab" id="{{tab.uniqueId}}" aria-controls="{{tab.tabPanelId}}" ng-disabled="tab.disabled">
{{tab.title}}
</b2b-tab>
</b2b-tabset>
<div class="tab-content">
....
</div>
As following the comments i changed the code to this. That did not throw an error, but did not work also:
<b2b-tabset tab-id-selected="vm.activeTabsId" ng-if="vm.selectedUserID" ng-model="vm.activeTabsId" ng-change="vm.changeTab()" >
<b2b-tab ng-repeat="tab in vm.gTabs" tab-item="tab" id="{{tab.uniqueId}}" aria-controls="{{tab.tabPanelId}}" ng-disabled="tab.disabled">
{{tab.title}}
</b2b-tab>
</b2b-tabset>
I am using a route file like this:
appDS2.config(function($routeProvider) {
$routeProvider
.when('/users', {
templateUrl: 'app/abcd/scripts/DS2-view-models/user.html',
controller : 'UserController as vm'
})

I have a LAMP website that i am trying to convert to be built on MEAN and I've split the index page into partials so i could have a SPA.
I am completely new to MEAN but i'm slowly learning and trying things however i'm now stuck on JQuery slider plugin that I am using in one of my partials and it does not load any images in the placeholder when the website is ran.
I know that i am supposed to use directives so that JQuery function is loaded after the partial page is loaded into the main page and hence why nothing is being displayed where the slider should be.
This is my partial page that contains the snippet of the slider for a single image (there are 3 of these 'li' blocks at the moment for 3 images):
home.html
<div id="pm-slider" class="pm-slider">
<ul class="pm-slides-container" id="pm_slides_container">
<li data-thumb="public/app/img/home/slide1a.jpg" class="pmslide_0"><img src="public/app/img/home/slide1.jpg" alt="img01" />
<div class="pm-holder">
<div class="pm-caption">
<h1>Medical professionals</h1>
<span class="pm-caption-decription">
that you can trust
</span>
learn more <i class="fa fa-plus"></i>
</div>
</div>
</li>
</ul>
</div>
My index.html file contains div ng-view tag where all of home.html should go.
app.js contains this code for routing and I know that here should go the .directives function for the JQuery plugin
var digiProm = angular.module('digiProm', [
'ngRoute']);
digiProm.config(['$routeProvider', function($routeProvider){
$routeProvider
.when('/', {
templateUrl: 'public/app/partials/home.html'
})
.when('/services', {
templateUrl: 'public/app/partials/services.html'
})
.otherwise({
redirectTo: 'partials/home.html'
});
}]);
After watching multiple videos as well as tutorials i can't figure out how i should write my directive function to work.. I am trying to work out how to use this type of format
digiProm.directive('slider', ['$rootScope', function($rootScope) {
return {
restrict: 'EA',
templateUrl: '/path/to/template',
link: function(scope, iElement, attrs) {
//attrs references any attributes on the directive element in html
//iElement is the actual DOM element of the directive,
//so you can bind to it with jQuery
$(iElement).bxSlider({
mode: 'fade',
captions: true
});
}
};
}]);
Is the templateUrl here supposed to be the path to the jquery file for the slideshow?
What the heck would go inside the link: function(...) ?? This script has been shown as an example on how to use the bxSlider and i'm trying to use a Pulse PM-Slider so not sure what functions i'm supposed to call for it to load after the partial has been loaded...
Any kind of help is much appreciated.
Thank you in advance
If the directive is only activating on an element that already exists in another template then you don't need templateUrl.
That is used to be able to inject html into an element. in other words a directive can define it's own template
Also the restrict is to tell directive whether to look for E-an element , or A an attribute or C- a class.
I suggest you add an attribute since it makes it easier to see later on in the markup
<div slider id="pm-slider" class="pm-slider">
Then remove templateUrl from your directive declaration object.
Also note that when jQuery is included in page before angular.js iElement is already a jQuery object so you can just use iElement.bxslider({....})
I have a JavaScript web app where I used AngularJS to ease things up, but now I bumped into a little problem.
I want to change viewfrom an ng-controller. I use $location.path to do this, but sadly, nothing happens. If I check the $location object, the path will be changed correctly, but the view isn't changing.
I have an ng-view in my Home.html. This is the config I wrote for it:
<html ng-app="app">
...
<body>
<div id="navigation-menu" ng-controller="NavigatorController">
<a class="menulink" ng-class="{ active: isActive('/labels')}" href="#page2">Page2</a>
<a class="menulink" ng-class="{ active: isActive('/labels')}" href="#page3">Page3</a>
</div>
<div ng-view></div>
</body>
</html>
This is the config I made for the $routeProvider which works flawlessly when used in the menusystem
myApp.config(function ($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'Page1.html',
controller: 'Page1Controller'
})
.when('/page2', {
templateUrl: 'Page2.html',
controller: 'Page2Controller'
})
.when('/page3', {
templateUrl: 'Page3.html',
controller: 'Page3Controller'
});
});
Upon opening the app I want to show the Page1.html in the ng-view, so that's sorted with the '/' url thing, I guess.
The problem is, that from every other controller, I want to be able to get back to the Page1.html.
I tried making an event in every other controller, like this:
$scope.NavigateBack = function() {
$location.path('/');
}
It's not working, sadly. I don't get any error messages though... I tried it with different addresses in the path, like "/page2", but nothing worked.
What am I doing wrong, that the view isn't changing and the page isn't navigating?
I recommend use
$window.location = "#/"
but don't forgot to inject $window to your controller
Define behaviour in the Page2Controller, for example:
$scope.goBack = function(){
$location.path("#/");
}
And add some button inside of Page2.html:
<button ng-click="goBack()">Return</button>
You might also need to change your navigation links href attribute to #/page2 and #/page3
Im trying to make my first modal using Angular, but it seems that the $modal cant even be found! Here is my code:
myController = ($scope, $modal) ->
$scope.OpenModal = ->$modal.open(
templateUrl: 'Modal.html'
)
And the HTML points to the OpenModal function as follows -
<div ng-controller="myController">
<button ng-click="OpenModal()">Modal</button>
</div>
But when I click the button, I get the error Cannot read property 'open' of undefined. Why is that? Shouldn't the modal object be injected in?
I found the issue. I had already included ui.bootstrap in my app, but I forgot to put $modal in the controller dependencies.
I worked through the tutorial on the AngularJS website and I noticed that in at step 7, they change how a controller is introduced into the application. Initially, they use a directive:
<body ng-controller="PhoneListCtrl">
...
</body>
However, it later gets changed to use a controller attribute as part of an ng-route.
$routeProvider.
when('/phones', {
templateUrl: 'partials/phone-list.html',
controller: 'PhoneListCtrl'
}).
/* rest of routes here */
Here's the git diff where the change is made. Is there a difference between these two techniques?
Controller using a ng-controller directive:
A new $scope is created on ng-controller element.
Explicit view-to-controller connection
Visible with inspect element, etc
Controller in a route:
A new $scope is created per route on the ng-view element.
The controller can request dependencies defined in the route resolve.
Optional view-to-controller connection. Recommended to have a naming convention that maps routes to controllers to views.
One of well-known feature of Angularjs is Single-Page Applications.
If you assign ng-controller attribute directly on the page：
<body ng-controller="PhoneListCtrl">
...
</body>
you can't switch controllers easily for other tasks.
So, use route to switch controllers is one of important step in learning Angular Single-Page feature.
You can have same layout and one different element by using route and ng-view directive.
$routeProvider.
when('/phones', {
templateUrl: 'partials/phone-list.html',
controller: 'PhoneListCtrl'
}).
when('/tablets', {
templateUrl: 'partials/tablet-list.html',
controller: 'TabletListCtrl'
}).
If '/phones'
<div ng-view></div>
will include your 'partials/phone-list.html' template
and set 'PhoneListCtrl' as div controller
The same：
If '/tablets'
<div ng-view></div>
will include your 'partials/tablet-list.html' template
and set 'TabletListCtrl' as div controller
This is the difference between two.
ng-view is the cause of the difference. You can't really do this
<div ng-view ng-controller="PhoneListCtrl">
As you'd need to change that controller as the route changed. So basically the router does that for you, and uses the controller you specified when you defined your routes.
You probably can do this:
<div ng-view>
and then in your template:
<div ng-controller="PhoneListCtrl">
and leave out the controller declaration in your routes. Which I suspect would have essentially the same effect, although I've never tried that. Probably better to go with convention here though.
In the 1st case the controller is directly on the page.
Once they change it, that controller is only on the page if the route is /phones otherwise it is some other controller based on some other route.
Yes - the change is this:
if you want to display a specific controller on the page, you can use
<body ng-controller>
BUT
if you want to do routing (application with more than one controller) - you will need to use routing + change the body to:
<body ng-view></body>
I am new to angularjs, was just trying to build a CRUD app with it.
My code is like this http://jsfiddle.net/fpnna/1/
And I am using apache as webserver, when turing on the
$locationProvider.html5mode(true);
then getting
uncaught TypeError: Object #<Ic> has no method 'html5mode' from testApp
When I am clicking to "Add new" the path changing to "/new" but getting error
404 The requested URL /new was not found on this server.
Any idea where I am doing wrong.
I went through the official manual, couldn't figure it out.
Thanks in advance.
You have a couple issues, first in jsfiddle you don't need the body tags plus you have multiple body tags. Also your fiddle has two ng-apps, the routes are defined incorrectly (should be /new for instance), invalid ng-view closing tag, there should only be one. You should include the javascript with No wrap in head and lastly it is html5Mode with a capital M on the mode and none of your partials exist at their urls nor are they defined as local scripts.
I would suggest you use plunkr as it allows you to add other local files, ie your partials which don't exist in the fiddle.
I've cleaned up all of the issues on this plunkr: http://plnkr.co/edit/A23Fxn9Ji02TGZ0jouZR?p=preview
angular.module('testApp', []).
config(function ($routeProvider, $locationProvider) {
$locationProvider.html5Mode(true); // case is important
$routeProvider.
when("/", {
templateUrl: "list.html"
}).
when("/new", { // make sure and use absolute link to route
templateUrl: "edit.html"
})
})
function testCtrl($scope) {
$scope.persons = [{
name: "X"
}, {
name: "Y"
}, {
name: "Z"
}]
}
and the html:
<body ng-controller="testCtrl" >
<div class="main-nav"> Add Me
</div>INDEX
<div >
<div ng-view>
</div>
</div>
</body>
