$compile unusual Behaviour

Angular version:1.3
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.

AngularJS - Dynamic HTML that contains the controller code

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 .

Jquery append() not working with angularjs

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.

Embedding AngularJS in existing jquery/bootstrap based website

We've got an existing application where the client-side is jQuery / Bootstrap. It consists of many tabs where each tab is defined in a module imported via. require.js. The tab javascript is handed a parent DOM element and is in charge of drawing itself inside of that element.
We'd like to start building new functionality (tabs) in AngularJS and running into some problems doing that.
My thinking is that we could tag the body with ng-app and in the main page code conjur up an app module window.app = angular.module('ourApp', []); and later, as tabs are loaded, create and wire-up the controllers.
I've built a simple single-page example that exhibits the problem we are having (below or here http://jsfiddle.net/p4v3G/1/).
The only way I've been able to get the example to work is manually calling angular.bootstrap which I'm pretty sure is wrong. Also, that only works the first time so if I click the button twice (equivalent to navigating to the tab, away from it, and back again within our app), Angular isn't wired up properly.
I'd appreciate any help.
<body ng-app='testApp'>
<div id="main" style="border: 1px solid #000; background: #ffdddd;">Click button to replace template and wire up controller...</div>
<button id="button1">Load</button>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.0-beta.14/angular.min.js"></script>
<script>
var app = angular.module('testApp', []);
jQuery(function() {
$("button").click(function() {
// controllers are wired up in click handler to simulate environment where we
// are looking to embed angular inside of an existing bootstrap/jquery application
// where new tabs (loaded as separate modules through require) are loaded on-demand.
app.controller('TestController', function($scope) {
$scope.message = 'Hello World, from Controller #1';
});
$("#main").html('<div ng-controller="TestController">{{message}}</div>');
// Bootstrap works the first click but not subsequent clicks
angular.bootstrap(document, ['testApp']);
});
});
</script>
</body>

To chunk up your appliation so that only the relevant parts are instantiated etc. what you need is angular ui-router. You would then set up a parent state for your tab-control with child states for each of your tabs. That way you both get deep linking and the performance you want with loading only the relevant tab.
As for requirejs, I encourage you to firstly consider if you really need it. In my opinion the javascript making up an angular application is usually much terser than a jquery application due to the declarative nature of the technology. Therefore loading all of the javascript at boot-time is ok. Your templates however may not be as simple, but by using templateUri references to templates they may be loaded as needed. (Personally I prefer compiling them to javascript and placing them in the $templateCahce at the cost of boot-time, but that's another matter.)
That being said, if my observations do not hold for your scenario/application/codebase, then others have had great success incorporating requirejs with angularjs. For a nice introductory talk on that subject see this nice ng-conf video.
Best of luck!

Could you be more precise, what type of errors appears.
You don't need use jquery. Check this code and compare

HTML
<body ng-app='testApp'>
<div ng-controller="TestController">
<span id="main" style="border: 1px solid #000; background: #ffdddd;">{{message}}</span>

Using Waypoints.js inside an AngularJS view

I am trying to use Waypoints inside a scrollable AngularJS view, however it's not working. I am trying to use ui.utils jQuery Passthrough but nothing happens. Here's what I have so far:
<body>
<div id="wrapper">
<div id="nav-menu">
<...>
</div>
<div id="main" class="main">
<div ng-view></div>
</div>
</div>
</body>
I am using the following template for the view:
<div class="fullScreenImage"></div>
<div ui-jq="waypoint" ui-options="test">test</div>
and my controller looks something like this:
app.controller('myController', ['$scope',
function ($scope) {
$scope.test = function(){
alert('You have scrolled to an entry.');
}}]);
My main element is scrollable but the window is not. Setting passthrough to the main div will trigger the test function, however I need it inside the template. Any suggestions?

Providing a JSFiddle or plunkr would be helpful.
But I suppose the issue is because the template is inside ngView.
As the content of the template is placed inside the ngView via XHR, the waypoints needs to be refreshed as discussed in the link http://imakewebthings.com/jquery-waypoints/#doc-refresh
An Angular directive will be more effective IMHO.

I had trouble with waypoints nested in ng-views as well.
My solution was just to wait till after the view had loaded to bind the waypoints, for this you can use $viewContentLoaded.
E.g.
myApp.run(['$rootScope', function($rootScope) {
$rootScope.$on('$viewContentLoaded', function(){
var waypoint = new Waypoint({
element: document.getElementById('waypoint'),
handler: function(direction) {
console.log('Scrolled to waypoint!')
}
})
});
}]);

I had the same problem. It's also possible to delay the binding with $timeout e.g $timeout(addWaypoints());.
