Angularjs add controller dynamically
Solution 1
This blog describes how to fiddle with angular to force it to load additional controllers after it has been bootstrapped:
Of course, this is completely unsupported, and could be broken by changes to angular at any time.
But, here is an updated version of your code using this method:
var app = angular.module('app', [])
app.config(
function($controllerProvider, $provide, $compileProvider) {
// Since the "shorthand" methods for component
// definitions are no longer valid, we can just
// override them to use the providers for post-
// bootstrap loading.
console.log("Config method executed.");
// Let's keep the older references.
app._controller = app.controller;
app._service = app.service;
app._factory = app.factory;
app._value = app.value;
app._directive = app.directive;
app.controller = function(name, constructor) {
console.log("controller...");
console.log(name);
console.dir(constructor);
$controllerProvider.register(name, constructor);
return (this);
};
// Provider-based service.
app.service = function(name, constructor) {
$provide.service(name, constructor);
return (this);
};
// Provider-based factory.
app.factory = function(name, factory) {
$provide.factory(name, factory);
return (this);
};
// Provider-based value.
app.value = function(name, value) {
$provide.value(name, value);
return (this);
};
// Provider-based directive.
app.directive = function(name, factory) {
$compileProvider.directive(name, factory);
return (this);
};
});
app.controller('AppCtrl', function($scope, $http, $compile) {
$scope.someData = {};
$scope.loadTemplate = function() {
$http.get("template.html")
.then(function(r) {
// load in the html, including the script, which will be executed
$(".dynamic-content").html(
r.data
);
// compile the loaded html into an actual template and put it back where it was
$(".dynamic-content").html($compile($(".dynamic-content").html())($scope));
})
}
});
Note that I used jQuery to place the HTML into the DOM, causing the script to execute, then to grab the HTML back out of the DOM so it could be compiled, after which I placed it back in the DOM again.
Also, there is an undefined variable in your template.html, so I updated it to look like this:
<script>
console.log('begin')
angular.module('app')
.controller('TempCtrl', function ($scope) {
$scope.total = 0;
console.log('inside')
$scope.update = function () {
$scope.total += 1;
};
});
console.log('end')
</script>
<div ng-controller="TempCtrl">
<h2>About</h2>
<h3>{{total}}</h3>
<p>Testing the total</p>
<button ng-click="update()">Update</button>
</div>

Updated Dave's example with angular components support
app.config(
function ($controllerProvider, $provide, $compileProvider) {
var app = angular.module('app');
// Let's keep the older references.
app._controller = app.controller;
app._service = app.service;
app._factory = app.factory;
app._value = app.value;
app._directive = app.directive;
app._component = app.component;
// Provider-based controller.
app.controller = function (name, constructor) {
$controllerProvider.register(name, constructor);
return ( this );
};
// Provider-based service.
app.service = function (name, constructor) {
$provide.service(name, constructor);
return ( this );
};
// Provider-based factory.
app.factory = function (name, factory) {
$provide.factory(name, factory);
return ( this );
};
// Provider-based value.
app.value = function (name, value) {
$provide.value(name, value);
return ( this );
};
// Provider-based directive.
app.directive = function (name, factory) {
$compileProvider.directive(name, factory);
return ( this );
};
// Provider-based component.
app.component = function (name, options) {
$compileProvider.component(name, options);
return ( this );
};
});

It looks like this questions already asked few times but there is no correct answer to it.
my case: i'm loading a template (with html and script) init to div using ajax (not using angular routing temple for some reason).
index.html (main)
<!DOCTYPE html> <html ng-app="app" ng-controller="AppCtrl"> <head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <title>Web</title> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.9/angular.min.js"></script> </head> <body> <div class="container body-content"> <div class="dynamic-content" > <!-- Loading content Here --> </div> <button ng-click="loadTemplate()">Load Template</button> </div> <script> angular.module('app', []) .controller('AppCtrl', function ($scope) { $scope.someData = {}; $scope.loadTemplate = function() { .... //AJAX to get the templet.html //and load it into .dynamic-content //then applying scope(); } }); </script> </body> </html>
template.html (template)
<div ng-controller="TempCtrl"> <h2>About</h2> <h3>{{total}}</h3> <p>Testing the total</p> <button ng-click="update()">Update</button> </div> <script> console.log('begin') angular.module('app') .controller('TempCtrl', function ($scope) { $scope.total = 0; console.log('inside') $scope.update = function () { $scope.total += 1; }; }); console.log('end') </script>
when i click the button
Load Template
it loads thetemplate.html
file in to container but i'm getting errorError: [ng:areq] Argument 'TempCtrl' is not a function, got undefined
though its being added to app controllers.
How can i add controllers dynamically and get it work with dynamic html nodes

Ja9ad335h about 8 yearsmy question is how to add dynamic controllers not how to get this example work..
-
Mindbender about 8 yearsI'm just curious now, what is the benefit you want to receive from this?
-
Ja9ad335h about 8 yearslike i mentioned.. i have 50+ template files with each template has its own controller(s). so cant put them all in one file and load at once
-
Ja9ad335h about 8 yearsanyhow i found a solution and updated my plunker plnkr.co/edit/EAa9Md36hDzpQ1BgIQKg?p=preview

Ja9ad335h about 8 yearsPerfect. this is exactly what i want.. Thanks Dave.
