I have this scenario, I am loading part of HTML (which has AngularJS directives) dynamically via script and I see AngularJS is not getting activated.
here is the example I am looking at. Is there anyway I can tell AngularJS to start bind on document ready? Loading an aspx page containing this widget1 content via a iframe seems to work but I am trying to avoid iframe and use client side script.
Appreciate any help.
<body ng-app>
main content page
<br />
<!-- widget1 -->
<b>Widget1</b>
<div id="widget1">
<!-- load below div via jquery/or any method from a remote html file-->
<script type="text/javascript">
$("div#widget1").load("/widgetsfolder/widget1.htm");
</script>
</div>
widget.htm file has below content.
<div ng-controller="TodoCtrl">
Total todo items: {{getTotalItems()}}
<ul class="unstyled">
<li ng-repeat="todo in todos">
<input type="checkbox" ng-model="todo.done" />
<span class="done-{{todo.done}}">{{todo.text}} </span></li>
</ul>
</div>
my controller code below.
`function TodoCtrl($scope) {
$scope.totalItems = 4;
debugger;
$scope.todos = [{
text: 'learn angularjs',
done: false
}, {
text: 'implement angularjs',
done: false
}, {
text: 'something else',
done: false
}, ];
$scope.getTotalItems = function () {
return $scope.todos.length;
}
}`

Apero's answer describes what is going on. I believe you are going to want to use ng-include. Your html would look something like this:
<body ng-app>
main content page
<br />
<!-- widget1 -->
<b>Widget1</b>
<div ng-include="'/widgetsfolder/widget1.htm'">
</div>
</body>
AngularJS evaluates the scope and renders the page after it is loaded.
Here, your js script loads the widget html but after Angular already compiled the scope etc.
I believe this will not work this way.
You can use angulars ngINclude to fetch outside documents, but I don't suggest it, it can be buggy. You can get the partials using either $http or $resource, this will fetch the data and compile the angular directives inside.
If you want to load the script using some other method, you can store the data as a string inside the controller and use a $compile directive in order to execute the angular code inside it.

I'm trying to add two angular apps / modules to one page.
In the fiddles below you can see that always only the first module, referenced in the html code, will work correctly, whereas the second is not recognized by angular.
In this fiddle we can only execute the doSearch2 method, whereas in this fiddle only the doSearch method works correctly.
I'm looking for the way how to correctly place two angular modules into one page.
Only one AngularJS application can be auto-bootstrapped per HTML document. The first ngApp found in the document will be used to define the root element to auto-bootstrap as an application. To run multiple applications in an HTML document you must manually bootstrap them using angular.bootstrap instead. AngularJS applications cannot be nested within each other.

I created an alternative directive that doesn't have ngApp's limitations. It's called ngModule. This is what you code would look like when you use it:
<!DOCTYPE html>
<html>
<head>
<script src="angular.js"></script>
<script src="angular.ng-modules.js"></script>
<script>
var moduleA = angular.module("MyModuleA", []);
moduleA.controller("MyControllerA", function($scope) {
$scope.name = "Bob A";
});
var moduleB = angular.module("MyModuleB", []);
moduleB.controller("MyControllerB", function($scope) {
$scope.name = "Steve B";
});
</script>
</head>
<body>
<div ng-modules="MyModuleA, MyModuleB">
<h1>Module A, B</h1>
<div ng-controller="MyControllerA">
{{name}}
</div>
<div ng-controller="MyControllerB">
{{name}}
</div>
</div>
<div ng-module="MyModuleB">
<h1>Just Module B</h1>
<div ng-controller="MyControllerB">
{{name}}
</div>
</div>
</body>
</html>

It's essentially the same code used internally by AngularJS without the limitations.
Why do you want to use multiple [ng-app] ? Since Angular is resumed by using modules, you can use an app that use multiple dependencies.
Javascript:
// setter syntax -> initializing other module for demonstration
angular.module('otherModule', []);
angular.module('app', ['otherModule'])
.controller('AppController', function () {
// ...do something
});
// getter syntax
angular.module('otherModule')
.controller('OtherController', function () {
// ...do something
});
HTML:
<div ng-app="app">
<div ng-controller="AppController">...</div>
<div ng-controller="OtherController">...</div>
</div>
EDIT
Keep in mind that if you want to use controller inside controller you have to use the controllerAs syntax, like so:
<div ng-app="app">
<div ng-controller="AppController as app">
<div ng-controller="OtherController as other">...</div>
</div>
</div>
You can bootstrap multiple angular applications, but:
1) You need to manually bootstrap them
2) You should not use "document" as the root, but the node where the angular interface is contained to:
var todoRootNode = jQuery('[ng-controller=TodoController]');
angular.bootstrap(todoRootNode, ['TodoApp']);
This would be safe.
Manual bootstrapping both the modules will work. Look at this
<!-- IN HTML -->
<div id="dvFirst">
<div ng-controller="FirstController">
<p>1: {{ desc }}</p>
</div>
</div>
<div id="dvSecond">
<div ng-controller="SecondController ">
<p>2: {{ desc }}</p>
</div>
</div>
// IN SCRIPT
var dvFirst = document.getElementById('dvFirst');
var dvSecond = document.getElementById('dvSecond');
angular.element(document).ready(function() {
angular.bootstrap(dvFirst, ['firstApp']);
angular.bootstrap(dvSecond, ['secondApp']);
});

NOTE: In html, there is no ng-app. id has been used instead.
I made a POC for an Angular application using multiple modules and router-outlets to nest sub apps in a single page app.

I am trying to render a directive and have it properly displayed in HTML with AngularJS. I have a service that takes care of displaying warning messages to the users. Per controller I can call this service and set a message I want to be displayed. Now one of those messages is supposed to include a link. However as I am using the Ionic framework I need to use a directive to accomplish exactly that.
HTML:
<div class="bar bar-loading bar-assertive top-bar">
| {{ message }}
</div>
JS:
$scope.message = "Please visit this link: <a ui-sref='app.settings.profile-show'>Open me.</a>"
However the message is not properly output in the html. If I use the following I get the html, but the directive is not evaluated:
<div class="bar bar-loading bar-assertive top-bar" ng-bind-html="message"></div>
How would I accomplish something like this? Thank you.
I am not sure about Ionic framework, But this is my way to render HTML content. Use $sce.trustAsHtml(html) to render text as html. Your code will look something like this.
// ...
app.controller('yourCtrl', function ($scope,$sce) {
$scope.message = "Please visit this link: <a ui sref='app.settings.profile-show'>Open me.</a>";
$scope.renderHTML = function(html_code){
return $sce.trustAsHtml(html_code);
};
}
html
<div class="bar bar-loading bar-assertive top-bar" ng-bind-html="renderHTML(message)"></div>
<!-- or this way? -->
<div class="bar bar-loading bar-assertive top-bar">
| {{ renderHTML(message) }}
</div>
<!-- not sure about second option, but either should work -->
Hope it helped!
I'm dealing with a content management system that needs to "inject" a reusable component into a page.
I want to inject the following component (html and javascript).
<script type="text/javascript">
if(typeof angular == 'undefined') {
document.write(unescape("%3Cscript type='text/javascript' src='/resources/scripts/lib/angular.min.js'%3E%3C/script%3E"));
document.write(unescape("%3Cscript type='text/javascript' src='/resources/scripts/pricing/app.js'%3E%3C/script%3E")); }
}
</script>
<div ng-app="pricing" ng-controller="PriceController as pc" ng-init="pc.getPrices('myprod', 'PER')">
Some text {{ pc.prices.msg["startdat tarief"] | jsDate }} .
More text {{ pc.prices.msg["einddat product"] | jsDate }}.
</div>
The component must be able to be injected multiple times on the page.
The problem is that the controller works fine, but only for the first injection.
This probably has something to do with that I am using the same app multiple times.
I am fairly new to angular.
How can I inject the same component multiple times?
Note that I am not able to init the app on a higher level. Because this would require the content manager to edit all pages, we juist want to inject a HTML component with javascript (i.e. the code snippet).
If you are able to add a unique ID to the module div you can manually bootstrap your angular app as follows:
function bootstrapAngular(id) {
angular.bootstrap(document.getElementById('module-' + id), ['app']);
}
angular.module('app', []).controller('sample', function ($scope) {
$scope.foo = 'bar';
});
bootstrapAngular(1);
bootstrapAngular(2);
bootstrapAngular(3);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div id="module-1">
<div ng-controller="sample">
{{ foo }}
</div>
</div>
<div id="module-2">
<div ng-controller="sample">
{{ foo }}
</div>
</div>
<div id="module-3">
<div ng-controller="sample">
{{ foo }}
</div>
</div>
You cannot have multiple ng-App directives on a single page. From the Angular.js documentation:
Only one AngularJS application can be auto-bootstrapped per HTML document. The first ngApp found in the document will be used to define the root element to auto-bootstrap as an application. To run multiple applications in an HTML document you must manually bootstrap them using angular.bootstrap instead. AngularJS applications cannot be nested within each other.
If placing ng-App higher in the tree isn't an option, you will have to re-write the components so that each component gets a unique angular.module() and when the component is injected, it will need to fire angular.bootstrap().
I have some markup and loaded controllers.
Then I load some modal window contents by ajax, which is using one of controllers I have defined before. But looks like this controller isn't being used, because he is not required until modal loaded.
Question: How to make controller work when modal loaded? I tryied $scope.$digest(), got error "digest in progress".
index.html
<html data-ng-app="foo">
<head>
<script src="/js/app.js"></script>
</head>
<body>
<div id="modal"></div>
</body>
</html>
js/app.js
!(function(){
function FormCtrl($scope) {
console.log($scope); // never fired
$scope.Submit = function() {
console.log('submit'); // never fired too :C
}
}
angular.module('foo', []).controller('FormCtrl', FormCtrl);
})();
html content loaded by ajax and inserted to #modal
<div data-ng-controller="FormCtrl">
<form name="signup" data-ng-submit="Submit()">
<!-- form data -->
</form>
</div>
SOLUTION:
$.modal().open({
onOpen: function($e) {
$http.get('/views/' + url).success(function(data) {
$compile(data)($scope, function(clonedElem) {
$e.html(clonedElem);
});
// $e.html(data); was used instead of statement above
});
}
});
If you want to inject new DOM elements into existing Anuglar app. You options are to use
ng-include: This has a src property that takes the url from which partial content has to be loaded. AngularJS would internally compile it. One important thing here is that angular will download the template as soon it encounter ng-include in html.
Download and compile DOM manually using the $compile service which is a more involved process.
If your AJAX content contains a controller defined in ng-controller, AngularJS would create it for you.
But in any case, keep in mind the controller script should have been already wired at the initialization\setup phase.
