Been struggling on how to tie angular with CSS animations... I'm sure I'm not getting something fundamental.
My goal is to have a list of search results. When you click one, a detail view will slide out from under the list. When you click another, the old detail view slides back, the details for the new one load, and then the detail view slides back in.
I don't have any code to show that even remotely works, but if anyone can point me at an example or offer some basic code, I would be extremely grateful.
Thanks!
You want to use ng-animate for animations.
ng-animate essentially adds CSS classes to elements automatically (often for a short time) during, for example, state transitions, during the population of an ng-repeat, etc.
You do not add the CSS classes to elements yourself this is done by ng-animate.
You do, however, apply the styling for those class in your style-sheet.
Its up to you, in your CSS, to do something with those automatically added CSS classes. Typically, you might want to do a fade in using CSS transitions.
For example ... https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Transitions/Using_CSS_transitions
OR
http://www.nganimate.org/
The ng-animate link details exactly which classes are added when. There are too many to mention here.
You might also want to use ng-fx
ng-fx github is here https://github.com/AngularClass/ng-fx
ng-fx requires ng-animate
ng-fx can be seen at work on its demo page - http://hendrixer.github.io/
This should get you going :)
I would go with ng-show.
var myApp = angular.module('myApp',[]);
myApp.controller('SomeController', ['$scope', function($scope) {
//this can be a service with a ngResource, an ajax call using $http... this is a baaaaasic dummy example.
$scope.yourScopeFunction = function(){
$scope.data = '';
$scope.data = {};
$scope.data.param1 = 'Hello';
$scope.data.param2= 'Jhon';
}
}]);
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
</head>
<body ng-app="myApp" ng-controller="SomeController">
<div >
<div class="elementClass" ng-click="yourScopeFunction()">Element1</div>
<div class="elementClass" ng-click="yourScopeFunction2()">Element1</div>
</div>
<div class="yourClass" ng-show="data != ''">
<div>{{data.param1}}</div>
<div>{{data.param2}}</div>
</div>
</body>
Then, when the ng-show's expression evaluates to true (the data variable has some content), Angular will attach a new class to your yourClass element called
.ng-hide-add and when it evaluates to false, Angular will add the class .ng-hide-remove.
You just have to make the transition (or animation you want) based on the classes your element will have in both those moments. Like in the documentation example.
Something like:
.yourClass.ng-hide-add{
//some transition or animation css
}
.yourClass.ng-hide-remove{
//some transition or animation css
}
Note that my function on the example does a $scope.data = ''; so the angular ng-show expression evaluates to false and the .ng-hide-remove is added.
By the way, you will need to add Angular Animations library.

I'm developing an AngularJS SPA, using ng-route and ng-animate. I'm trying to display the Bootstrap Carousel on the index.html#/ using ng-show. Very simple task.
I want the Carousel to show on the index page, but not on the about page or the contact page.
I'm trying to do the logic in my indexController like so:
if ($location.path() == "/") {
$scope.isIndexPage = true;
}
And in my HTML:
<div id="myCarousel" class="carousel slide" data-ride="carousel" ng-show="isIndexPage">
But it does not work as expected: the Carousel does not display. Once the ng-show attribute is removed, the carousel displays, but on all pages.
How can I get the Carousel to display only on the index page? I've tried variations such as ng-include-ing and ng-ifing carousel.htm. Numerous Google searches such as "AngularJS SPA and Bootstrap Carousel" reveal unanswered SO questions.
Thanks in advance for any input. Here's the PLUNKER.
It's a bit strange not to put something that is specific to the home page into the template of the home page, but anyway...
Your code has 2 main problems:
you're trying to access a variable from the indexController scope from a part of the page that is not controlled by this controller. The controller only controls its view. The $scope of the controller is limited to its view.
You're initializing the isIndexPage variable only once. It never changes after.
Solution:
create a controller for the whole body of the page, and put the logic used to control the visibility of the carousel in that controller
use a function that will return true or false based on the current location
See http://plnkr.co/edit/8luxeIbyIPEKy0LkemM0?p=preview for a fork of your plunker (the additional JS code is at the end of script.js):
appname.controller('MainCtrl', function($scope, $location) {
$scope.isIndexPage = function() {
return $location.path() === '/';
}
});
and in the index.html file:
<body ng-controller="MainCtrl">
<div ng-show="isIndexPage()" ...>
I'm a bit new in angular.js and I wonder how to proper implement fullpage.js into angular.js. I tried to add fullpage as example ...
this code direct into controller i wanted to use for fullpage.js
$('#fullpage').fullpage({
sectionsColor: ['#21f7ff', '#bdcc4b', '#fcae49'],
});
but the problem is when I put this code into controller i wont recongnize nothing else... ( other functions for click)
my exmaple of implementation in controller :
'use strict';
angular.module('APP')
.controller('MainCtrl', function ($scope,Auth) {
$('#fullpage').fullpage({
sectionsColor: ['#21f7ff', '#bdcc4b', '#fcae49'],
});
$scope.moveUp = function(){
$.fn.fullpage.moveSectionUp();
};
$scope.moveDown = function(){
$.fn.fullpage.moveSectionDown();
};
});
view :
<div id="fullpage">
<div class="section">
<button class="button" ng-click="moveDown()">Down</button>
</div>
<div class="section">
<button class="button" ng-click="moveUp()"> Up </button>
</div>
</div>
I'm using angular-fullastack-generator for project start so this is a partial view.
My general question is how to proper implement fullpage.js into angular.js ?
Update Nov 2018:
Now you can make use of the official fullPage.js wrapper for Angular.
If you take a look at fullPage.js FAQs you will find this:
My javascript/jQuery events don't work anymore when using fullPage.js
Short answer: if you are using options such as verticalCentered:true or overflowScroll:true in fullPage.js initialization, then you will to treat your selectors as dynamic elements and use delegation. (by using things such as on from jQuery). Another option is to add your code in the afterRender callback of fullpage.js
Explanation: if you are using options such as verticalCentered:true or overflowScroll:true of fullPage.js, your content will be wrapped inside other elements changing its position in the DOM structure of the site. This way, your content would be consider as "dynamically added content" and most plugins need the content to be originally on the site to perform their tasks. Using the afterRender callback to initialize your plugins, fullPage.js makes sure to initialize them only when fullPage.js has stopped changing the DOM structure of the site.
Which means you would need to use delegation for your events (such as click) or add them in the afterRender callback.
I am new to angularjs, and I have an jquery background.
I want to compile json from the server into an element with an template.
What I now have for so far is:
The template:
<script type="text/ng-template" id="/tiles.html">
<div ng-repeat="tile in tiles">
{{tile.name}}<img ng-src="tile.src" />
</div>
</script>
The button for displaying the content:
<button ng-click="imageOptions.addFromList()">+ Add Image from list</button>
The function:
$scope.imageOptions.addFromList = function (){
$http
.get('/json/Tiles/get')
.success(function(data){
$scope.tiles = data;
console.log(data);
})
.error(function(data){
console.log("something did go wrong");
});
$(".prompt").html('<div ng-include src="/tiles.html"></div>');
};
The placeholder:
<div class="prompt"></div>
The placeholder will be used many times with also other content.
So I can not just type the html from the .html() argument. Like this:
<div class="prompt"><div ng-include src="/tiles.html"></div></div>
When I inspect the .prompt div it will stay uncompiled
The first thing you should do is remove jQuery library from your app while you get familiar with angular methodology.
There is no need to use html() method when all you need to do is include your template through a variety of different ways in your html source.
If the data isn't already available for ng-repeat it will simply fail quietly and do nothing. Then when the data is available it will respond automatically.
You could simply do:
<div class="prompt" ng-include src="/tiles.html"></div>
Or you could make a simple directive that will accomplish the same thing .
app.directive('prompt', function() {
return {
restrict: 'C',/* use for "class" */
templateUrl: '/tiles.html'
}
});
Simply change this
<div ng-include src="/tiles.html">
to this
<div ng-include src="'/tiles.html'">
While coding your single page application in angularjs, ideally there should not be any need for you to first get a reference to an element and then perform some action on it (You may think of this as the first step of switching from a jquery background to angularjs domain).
To achieve complete separation of model, view and controller you should just define your templates and controllers accordingly. These mappings and references should be managed by angularjs on its own.
As correctly mentioned above you should not be using .html() method of jquery. If you have included jquery in your document, it will be internally used by angularjs, but, including jquery should not be mandatory for using angularjs.
ng-repeat and ng-include also create a separate scope, so you may want to take care of those as well in future.
For your query, you may reference the template by including extra quotes in ng-include as:
<div class="prompt">
<div ng-include src="'tiles.html'"></div>
</div>

In a AngularJS (1.2.7) project, using UI Router (0.2.8), I want to apply the current state as a class to the ui-view element, because that would allow me to apply animations for specific states, e.g. do transition A going from login to start and do transition B going from start to settings.
At the moment I have the $state object on the $rootScope (as mentioned here, which allows me to add a state-based class on the body using ng-class="$state.current.name". However, if I add that to the ui-view element, e.g.
<div ui-view ng-class="$state.current.name"></div>
Then the class is one step behind the actual state. So when going from "login" to "start", the class will be "login" instead of "start".
I think this is a bug, you can read more about the issue here:
https://github.com/angular-ui/ui-router/issues/866
Until it is fixed I suggest such a workaround:
<div ng-class="$state.current.name"><div ui-view></div></div>
I'm reading between the lines of what I think you're trying to do: you want to style a particular view differently depending on the state/route. Here's what I'm doing currently:
1) Set a state attribute on the HTML element:
<html lang="en" ng-app="MyApp" ng-controller="MyAppCtrl" state="{{ state }}">
<div ui-view="nav"></div>
<div ui-view="page" autoscroll="true"></div>
</html>
2) Update the state name whenever the route changes:
app.controller('MyAppCtrl', function($rootScope){
$rootScope.state = 'home';
$rootScope.$on('$stateChangeSuccess', function(event, toState) {
$rootScope.state = toState.name;
});
});
3) Using attribute selectors in the stylesheets:
[state="app.articles"] [ui-view="page"] {
section {
font-size: 1.8rem;
}
}
Instead of adding $state to $rootScope I just put a method on the controller of my root directive that returns the active state name. Then I added to the DOM like so:
<ui-view active-state="{{ctrl.getActiveState()}}"></ui-view>
Then in my CSS I can use selectors like this:
[active-state="someStateName"] { ... }
If you prefer a class it would be just as easy to do this:
<ui-view class="{{ctrl.getActiveState()}}"></ui-view>
...but you would want to replace all "." characters with "-" in your getActiveState() method.
but, i has question about that : <div ng-class="$state.current.name"><div ui-view></div></div>
$state.current.name equal user.login hou to code my css?
I have a tabbed navigtion in my webapp that looks like this
Now I want to Change the directive each time the user clicks on one of the Navigation points. My Idea was to init the page with the first template.
$scope.currentDirective = $compile('<div order-Sale></div>');
Then when the user clicks on a tab, I wanted to change and compile the content again with a new directive in it. But for some reason this is not working. How would you proceed in order to archive this dynamic content loading? I really want to only load the content on necessary need and not just to show or hide it. I think using directives is the right way to go for it, but I'm a but stuck at the implementation... Someone any pointer ? (I don't want to use any jQuery)
What I tried [Edit]:
The controller.js
app.controller('pageController',['$scope','$compile', function($scope, $compile){
var templates = ['<div first-template></div>','<div second-template></div>'];
$scope.currentTemplate = $compile(templates[0]);
$scope.changeTemplate = function(id) {
$scope.currentTemplate = $compile(templates[id]);
};
}]);
The HTML
<div ng-controller="pageController">
<li>
<a ng-click="changeTemplate('1')">Change Template</a>
</li>
{{currentTemplate}}
</div>
UPDATE
$compile returns a linking function not a value, you cannot just bind it to your template with interpolation.
You should use ngBindHtml instead of regular bindings ( ngBind & {{ }} ).
ngBindHtml does compiling, linking and watching all out-of-the-box.
With ng-bind-html-unsafe removed, how do I inject HTML?
Here is a plunker
app.controller('pageController',['$scope','$compile','$sce', function($scope, $compile, $sce){
var templates = ['<div>first-template</div>','<div>second-template</div>'];
$scope.currentTemplate = $sce.trustAsHtml(templates[0]);
$scope.changeTemplate = function(id) {
$scope.currentTemplate = $sce.trustAsHtml(templates[id]);
};
}]);
The markup:
<div ng-controller="pageController">
<button ng-click="changeTemplate('1')">Change Template</button>
<div ng-bind-html="currentTemplate"></div>
</div>
For more robust dynamic content loading you have two good alternatives:
ngRoute from angular team.
ui-router from angular-ui team.
If you want to change and compile the content again, well that's exactly what ng-view/ ui-view directives already do for you.
Why not just use a directive:
You probably need to load a different template (html partial) for each tab.
You probably need to change the url based on the tab (and vice versa)
You probably need to instantiate a different controller for each tab.
ngRoute and ui-router come with their own directives.
You can implement your own route module if you want but that's more than just a directive.
