We are working with jquery 1.9.1 and angular 1.2.13. We are using a wysiwyg editor that works great, we save the html into the database and load the html back using jquery append function and works fine. Now we are trying to append the same html into a div tag (the wysiwyg editor also uses a div) and the append function it's not working. We check in the console, and the string we are trying to append is there, also jquery grabs the element (also checked in the console log) but the append function it's not working.
PD: I apologize for my english
The html
<div data-ng-controller="PreviewCtrl">
<div class="container">
<div id="resumenPreview"></div>
</div>
</div>
The controller
angular.module('module').controller('PreviewCtrl', ['$scope', '$routeParams', '$location', '$http', 'selectedElement',
function ($scope, $routeParams, $location, $http, selectedElement) {
$scope.id = $routeParams.id;
$scope.mensaje = $scope.id;
$scope.imagen = null;
$scope.dataImagen = null;
//is not working either
$('#resumenPreview').append("hola");
$scope.pageLoad = function () {
var x = selectedElement.data.Resumen;
//This is properly displayed in the console
console.log(x);
//This too, is displayed in the console log
console.log($('#resumenPreview'));
// Why this isn't working? I'am clueless
$('#resumenPreview').append(x);
};
$scope.pageLoad();
}]);
My guess would be there are multiple divs with id="resumenPreview". But this is clearly the wrong way to handle such things in angular. There shouldn't be dom-manipulation in the controller - directives should take care of dom-related stuff. Put the html-string into the scope and let angular handle the injection into the dom:
instead of $('#resumenPreview').append(x); do $scope.resumenPreview = x;
and in the template do this:
<div class="container">
<div ng-bind-html="resumenPreview"></div>
</div>
Solve it with angularjs for the ng-bind-html to work it's necessary to include
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.3/angular-sanitize.js"></script>
and to add 'ngSanitize' as a dependency in the app module configuration. And then just do what #Johannes Reuter posted.
Thanks everybody, Greetings.

I am using node and angularjs. I have a frame like page inside an ejs that is passed content to load into the includes dynamically.
<div ng-app="thisApp">
<div ng-controller='MainCtrl'>
{{ firstMessage }}
<div id='contentFromNode' ng-include='<%= pageContent %>'></div>
</div>
</div>
<script>
var thisApp = angular.module('thisApp', []);
thisApp.controller('MainCtrl', [ '$scope', function($scope) {
$scope.firstMessage = "Main Controller Working Fine";
}])
</script>
and then the passed content might be just an html page containing something like this:
<div ng-controller='NestedCtrl' id='content-type-container'>
{{ nestedMessage }}
</div>
<script>
thisApp.controller('NestedCtrl', [function(){
var nested = this;
nested.nestedMessage = "Nested Won't Work";
}])
</script>
So I have tried $scope within the NestCtrl instead of referencing this, I have tried moving the script tag above and below (ideally this get separated eventually anyway). I have tried aliasing the controllers, however my problem is the in registration of the controller itself as I get that great Error: [$controller:ctrlreg] error. The page is loading the content fine? Any ideas what I am doing wrong here?
Seems JQlite doesn't support this. You have to include jquery or lazy load the script. Refer

I am trying to compile the html and generate the interpolated html. the ng-if code is getting commented out
html
<div ng-if="true">true</div>
I am using the above html as htmlTemplateDom
Controller
var htmlCompiledDom = $compile(htmlTemplateDom)($scope);
var div = angular.element("div#emailContent").append(htmlCompiledDom);
console.log(div.html());
Console
<!-- ng-if:true -->
So the problem is ng-if is getting commented out.
Someone help !!!!
I don't see any problems on $compile.
This example works just as expected, check if you're doing something different.
HTML:
<div ng-app="app" ng-controller="controller">
<div id="compile">
</div>
</div>
Javascript:
angular.module('app', [])
.controller('controller', function ($scope, $compile) {
var template = '<div ng-if="true">true</div>';
var content = $compile(template)($scope);
angular.element('div#compile').append(content);
});
If you want to execute it, take a look at this fiddle.
I have a AngularJS page that displays a popup. The HTML for the popup is dynamically retrieved from the server using an AJAX call. This dynamic HTML contains a new controller and the necessary AngularJS code for the controller as well.
This code works only if the child page JavaScript code is present in the parent page.
I would like to keep all the child page code in the child page itself.
Can someone please point out what I am doing wrong?
Main Page
<div id="mainPage" ng-controller="mainController">
Contains a table that displays a bunch of rows.
</div>
<div id="popup">
Dynamic HTML retrieved from AJAX goes here.
</div>
<script type="text/javascript">
angularMainApp.controller('mainController', ['$scope', '$http', '$compile', function ($scope, $http, $compile)
{
$scope.activateView = function(ele)
{
$compile(ele.contents())($scope);
$scope.$apply();
};
$scope.buttonClick = function()
{
$("#popup").html( dynamicHTMLThroughAJAX );
$scope.activateView($("#divCreateTemplatePopup"));
return;
}
return;
}]);
</script>
Dynamic HTML Content
<div ng-controller='childController'>
Some HTML here.
</div>
<script type="text/javascript">
angularMainApp.controller('childController', ['$scope', '$http', function ($scope, $http)
{
}]);
</script>
Angular need to know that you changed the content and realize that it should update it self too .
so , what you have to do is tel him that apply the watchers and other stuff to the current DOM .
for doing that you shall use $scope.$apply(); . by calling this function you force angular to add watchers and other stuff's to the DOM and now it can work with you'r new contents too .
i suggest you to read about digest in angularjs and see how it works .
here's some link about your problem to see the problem better :
AngularJS and scope.$apply
Digest cycle and $scope
AngularJs docs : $scope.$apply()
When to use $scope.$apply()
AngularJS: $watch, $digest and $apply
good luck and have fun .
Is it possible to css animate a div (background-color) that is outside the ng-view, using a directive on a $state inside the ng-view?
The ng-view has css animations for the routing.
If I do not animate the div then the ng-view anims work fine, but..
If I add animation classes to the div(bgId) then the routing anims do not fire.
Here is a sample of html: (Button added as example - would normally be in the template pages eg. home.html / login.html )
<body ng-app="app" ng-controller="MainCtrl">
<div id="bgId" class="{{colorVal}}">
<ion-nav-view animation="slide-left-right">
</ion-nav-view>
</div>
<button swapcolour="changeColour()" data-nxtpage="1">change colour</button>
</body>
This is controlled by a directive(swapcolour) that gets the nxtpage value from the button attr and updates the colorVal in MainCtrl.
//MainCtrl.js
.controller('MainCtrl', ['$scope', '$state', function($scope, $state) {
$scope.colorVal = 'redBg';
}])
//Directive.js
.directive('swapcolour', function ($rootScope, $state) {
var pageArr = [{home:'redBg'},{login:'blueBg'}];
return function (scope, element, attrs) {
var nextPageNum = attrs.nxtpage;
var obj = pageArr[nextPageNum];
var item = Object.keys(obj);
var objItem = obj[item];
element.bind('click', function () {
$state.transitionTo(item[0]);
$rootScope.$$childHead.colorVal = objItem;
});
}
}])
I do not know why it fails. Any ideas?? I am new to directives. (Trying to setup a plunker, but having issues getting ionic working with it)
I fixed it! - I think.
Basically after totally stripping the application to its bones I managed to build a plunker and got it working.
There was nothing wrong with my code after all.
<body ng-app="app" ng-controller="MainCtrl">
<div id="bgId" class="{{colorVal}}">
<ion-nav-view animation="slide-left-right">
</ion-nav-view>
</div>
</body>
http://plnkr.co/edit/Oug8zD?p=preview
Then I tried this code on my app - and it still did not work! So I tried replacing my ionic.bundle.js and ionic.css files (orig installed using npm) with the files used in the plunker (1.0.0-rc.1) and my app worked :)
Hope this helps others in trouble in the future.
I have an AngularJS app which (reduced to relevant parts) looks like this:
<div ng-app="myModule">
<div id='container'>
<div say-hello-to name="Frank">f</div>
<div say-hello-to name="Billy">b</div>
</div>
</div>
the application works fine. Now, if after the angular bootstrapping process, I add a new dom element, which corresponds to a directive, it isn't interpreted. Note that the "Addition" is done by non-angularjs JavaScript Code.
<div say-hello-to name="Dusty">d</div>
it is just "dead" div.
JsFiddle Link: http://jsfiddle.net/Nn34X/
The question is: How can I add a new DOM Element into the application and let AngularJS know that there is a new Element to be interpreted (I could easily point angularjs exactly to all inserted elements)
Cheers, and thanks in Advance!
Retrieve the $injector service:
var $injector = angular.element(document.querySelector('#container')).injector();
Select the element:
var element = angular.element(document.querySelector('[name="Dusty"]'));
Use the $injector service to retrieve the $compile service and link the element to the scope:
$injector.invoke(function ($compile) {
var scope = element.scope();
$compile(element)(scope);
});
