The examples I see of using angular-ui/bootstrap's $modal always look something like this:
$modal.open({
templateUrl: 'modaltemplate.html',
controller: function($scope) {
...
}
});
What if I want to use a directive, instead? Like this:
$modal.open({
template: '<my-modal-directive></my-modal-directive>'
// no "controller" property; use directive's controller
});
The markup for my-modal-directive renders fine, and I've moved the controller property into the my-modal-directive definition object, but now getting this error from the my-modal-directive:
Error: [$injector:unpr] Unknown provider: $modalInstanceProvider <- $modalInstance
Can anyone point me to an example where $modal uses a directive where that directive defines the controller?
For example, this works, where I've replaced the templateUrl with a directive:
http://plnkr.co/edit/YrGaF83GH6bzZPRR55GK?p=preview
But when I move the controller from $modal.open() into the directive, that's when the error happens:
http://plnkr.co/edit/aLBT239EpL004DRh4jll?p=preview
The problem is that $modalInstance can only be injected in the controller that you provide to $modal.open.
Check out the sources here:
$modal.open = function (modalOptions) {
...
var modalInstance = {
...
};
...
if (modalOptions.controller) {
...
ctrlLocals.$modalInstance = modalInstance;
...
ctrlInstance = $controller(modalOptions.controller, ctrlLocals);
...
}
...
}
In essence when you try to add $modalInstance as a dependency to your controller AngularJS looks for a registered global provider named $modalInstanceProvider. Now the trouble is, if you understood the code above, that $modalInstance is not a globally registered provider. It only "exists" as a dependency for the controller you pass to $modal.open.
If you read the rest of the code you'll notice that $modal.open returns modalInstance, maybe you can use that.
Something like this:
function SomeController($modal) {
$scope.modal = {
instance: null
};
$scope.modal.instance = $modal.open({
template: '<my-modal-directive modal="modal"></my-modal-directive>',
scope: $scope
});
}
function MyModalDirective() {
scope: {
modal: '='
},
link: function($scope) {
// here you can access $scope.modal.instance
}
}
The issue you have is that you are trying to inject values which are not available for injection. Only values registered with the injector can be injected.
The logic of you code is also flawed, you are creating the modal in your main controller but trying to close it in the directive. Ideally, the modal should be triggered by the directive (via it's link function), and then you can ok/cancel it from there.
See my http://plnkr.co/edit/3p1rXAymd7BilyklgxKy?p=preview for one possible approach, I have kept the code that closes and cancels the modal in the main controller.
angular.module('ui.bootstrap.demo', ['ui.bootstrap']);
angular.module('ui.bootstrap.demo').directive('myModal', function() {
return {
restrict: 'E',
templateUrl: 'myModalContent.html',
controller: function ($scope) {
$scope.selected = {
item: $scope.items[0]
};
}
};
});
angular.module('ui.bootstrap.demo').controller('ModalDemoCtrl', function ($scope, $modal, $log) {
$scope.items = ['item1', 'item2', 'item3'];
$scope.open = function (size) {
var modalInstance;
var modalScope = $scope.$new();
modalScope.ok = function () {
modalInstance.close(modalScope.selected);
};
modalScope.cancel = function () {
modalInstance.dismiss('cancel');
};
modalInstance = $modal.open({
template: '<my-modal></my-modal>',
size: size,
scope: modalScope
}
);
modalInstance.result.then(function (selectedItem) {
$scope.selected = selectedItem;
}, function () {
$log.info('Modal dismissed at: ' + new Date());
});
};
});
I create a directive to create modals easily. A modal content is based on a template view.
angular.module('your_app').directive('modalViewUrl', function ($modal) {
return {
restrict: 'A', // A: attribute
scope: { // isolate scope
'modalViewUrl': '#', // modal view url to render the modal content
'modalController': '#' // modal view controller (optional)
},
link: function($scope, element, attrs){
element.bind('click', function(){
var template =
'<div class="modal-body">' +
'<button ng-click="$close()" type="button" class="close" aria-label="Close">' +
'<span aria-hidden="true">×</span>' +
'</button>' +
'<div ng-include="\'' + $scope.modalViewUrl + '\'"></div>' +
'</div>';
// see modal reference from ui bootstrap at <http://angular-ui.github.io>
var modalInstance = $modal.open({
animation: true,
template: template,
controller: $scope.modalController,
});
});
}
};
});
Example how to use it:
index.html
<a modal-view-url="hello.html" modal-controller="HelloCtrl" href="#">
Click here to open the modal
</a>
hello.html
<h1> Hello World {{name}} </h1>
HelloCtrl.js
angular.module('yourApp').controller('HelloCtrl',
function ($scope, $modalInstance) {
// $modalInstance: same from from ui bootstrap
$scope.name = "Xico";
});
A modal view can have its own controller. Example:
hello.html (modified)
<h1 ng-controller="Hello2Ctrl"> {{msg}} {{name}} </h1>
Hello2Ctrl.js
angular.module('yourApp').controller('Hello2Ctrl',
function ($scope) {
$scope.msg = "Hello Worldsszz";
$scope.name = "Zefa";
});
Observe that the modal output will be "Hello Worldsszz Xico", because the modal controller (HelloCtrl) will be rendered after view controller (Hello2).
Reference
It's even more late reply, but someone may find it useful.
I have enhanced Fernando Felix answer and made my own quite flexible directive which communicates with the controller, which I think might be solution for this question.
Directive
var modalUrl = function ($modal) {
return {
restrict: 'A', // A: attribute
scope: { // isolate scope
'modalUrl': '#', // modal view url to render the modal content
'modalController': '#', // modal view controller (optional)
'value': "="
},
link: function(scope, element, attrs){
console.log('modalUrl link');
var modalInstance;
var template = [
'<div class="modal-body">',
'<button ng-click="$close()" type="button" class="close" aria-label="Close">',
'<span aria-hidden="true">×</span>',
'</button>',
'<div ng-include="\'' + scope.modalUrl + '\'"></div>',
'</div>'
].join('');
element.bind('click', function(){
// see modal reference from ui bootstrap at <http://angular-ui.github.io>
modalInstance = $modal.open({
size: attrs.size,
animation: true,
template: template,
resolve: {
params: function () {
console.log('value passed to modal:');
console.log(scope.value);
return scope.value;
}
},
controller: scope.modalController
});
modalInstance.result.then(
function (returnValue) {
// alert('value: '+returnValue);
console.log('modal returnValue:');
console.log(returnValue);
scope.value = returnValue;
}, function () {
console.log('Modal dismissed at: ' + new Date());
}
);
});
}
};
}
modalUrl.$inject = ['$modal'];
angular.module('app').directive('modalUrl', modalUrl);
Controller
var HelloCtrl = function ($scope, $modalInstance, modalVal) {
// $modalInstance: same from from ui bootstrap
console.log('Hello init!');
// modalVal is the init modal value passed via directive
console.log(modalVal);
// your code
$scope.name = modalVal;
$scope.ok = function() {
$modalInstance.close(this.name); // returnValue
};
$scope.cancel = function() {
$modalInstance.dismiss('cancel');
};
}
HelloCtrl.$inject = ['$scope', '$modalInstance','params'];
angular.module('app').controller('HelloCtrl',HelloCtrl);
inline template
<script type="text/ng-template" id="hello.html">
<div class="modal-header">
<h3 class="modal-title">I'm a modal!</h3>
</div>
<div class="modal-body">
<input type="text" ng-model="name" />
</div>
<div class="modal-footer">
<button class="btn btn-primary" ng-click="ok()">OK</button>
<button class="btn" ng-click="cancel()">Cancel</button>
</div>
</script>
It's one controller and template per popup type, then you can call it multiple times with:
<a modal-url="hello.html" modal-controller="HelloCtrl" value="yourVal" ng-init="yourVal='test'" href="#">Click here to open the modal</a>
You can initialize value with whatever - ie. object, array etc.
or external template
Pretty much the same, just url changes and template file is used for template.
<a modal-url="/modal/test1.html" modal-controller="HelloCtrl" value="yourVal" ng-init="yourVal='test'" href="#">Click here to open the modal</a>
test1.html
<div class="modal-header">
<h3 class="modal-title">I'm a modal!</h3>
</div>
<div class="modal-body">
<input type="text" ng-model="name" />
</div>
<div class="modal-footer">
<button class="btn btn-primary" ng-click="ok()">OK</button>
<button class="btn" ng-click="cancel()">Cancel</button>
</div>
Modal size etc.
Just add parameter size="sm|lg" for the modal link/button ie.
Click here to open the modal
For standard size skip the parameter.
You may enhance it yourself using link function attrs.
I'm kanda late replay put simplest way is to use
$scope.$parent.$close(result);
$scope.$parent.$dismiss(reason);
This works form your directive controller.

Prompt as from a directive to cause a method of the controller.
Directive
app.directive('scroll', function($location){
return{

link: function(scope, element, attrs){
element.on('scroll', function(){
let fh = $('#ngview').height();
let nh = Math.round($(element).height() + $(element).scrollTop());

app is the main application module
var app = angular.module('app',
[
'ngRoute',
'lastUpdateModule',
'selectedByGenreModule',
'currentFilmModule',
'httpFactory',
'userModule',
'accountModule'
]);
The controller from which you want to call the method is described in a separate file
and connects via require
const SelectedByGenreModule = require('../controllers/selectedByGenre.controller.js')
and passed as a dependency to the main module
So it is from this controller that I need to call the method in the directive.
Tell me how to do it correctly. I left through $rootScope but it did not work out
As far as I know, the directive has the same scope as the controller in which it is located. That is, the directive is in the controller which is the parent for the controller from which you need to call the method.
It sounds like you want your directive to trigger an action defined by your controller. I'd recommend passing the function to the directive via the scope property. See the example below.
var app = angular.module('ExampleApp', []);
app.directive('scroll', function($location) {
return {
restrict: 'A',
scope: {
scroll: '='
},
link: function(scope, element, attrs) {
element.on('scroll', function() {
let fh = $('#ngview').height();
let nh = Math.round($(element).height() + $(element).scrollTop());
if (fh == nh) {
scope.scroll();
}
})
}
}
});
app.controller('ExampleCtrl', function($scope) {
$scope.onScroll = function() {
console.log('Scrolled!')
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

You can require parent controllers using the require property when defining the directive, the ^^ tells angular to look up the DOM for a parent, otherwise it will only look on the local element.
app.directive('scroll', function($location){
return{
restrict: 'A',
require: '^^selectedByGenreCtrl', // Use the correct controller name here
link: function(scope, element, attrs, selectedByGenreCtrl){
element.on('scroll', function(){
let fh = $('#ngview').height();
let nh = Math.round($(element).height() + $(element).scrollTop());
if(fh == nh){
//Here we do what we need
}
})
}
}
});

I'm stuck on how to pass value from trigger (a href) to modal button (a href).
You can send data into modal controller pass through resolve object:
var modalInstance = $modal.open({
animation: $scope.animationsEnabled,
templateUrl : 'SubmissionReminder.html',
controller: 'SubmissionReminder',
resolve: {
refno: function () {
return {refno: $scope.refno};
}
}
});
Then get resolved refno from modal controller:
app.controller('SubmissionReminder', function ($scope, $modalInstance, refno) {
$scope.refno = refno().refno;
...
}
I need to create a directive that can be used inside Angular UI modal. This directive also need to know about modal's controller in order to use some functions from it. What I have now:
JS:
'use strict';
var DemoApp = angular.module('DemoApp', [ 'ui.bootstrap' ]);
DemoApp.controller('PageController', ['$scope', '$modal', function($scope, $modal){
$scope.openModal = function(){
var scope = $scope.$new(true);
$modal.open({
'templateUrl' : 'modal.html',
'controller' : 'ModalController',
'scope' : scope
});
}
}]);
DemoApp.controller('ModalController', ['$scope', '$modalInstance', function($scope, $modalInstance){
$scope.ok = function() {
$modalInstance.dismiss();
};
$scope.cancel = function() {
$modalInstance.dismiss();
};
}]);
DemoApp.directive('expression', function() {
return {
restrict : 'A',
require : ['ngModel', '^ModalController'],
link : function(scope, element, attrs, controllers) {
console.log(arguments);
}
};
});
Modal template:
<div class="modal-header">
<h3>Test!</h3>
</div>
<div class="modal-body">
<input data-ng-model="someValue" expression>{{someValue}}
</div>
<div class="modal-footer">
<button class="btn btn-primary" data-ng-click="ok()">Ok</button>
<button class="btn btn-warning" data-ng-click="cancel()">Cancel</button>
</div>
And the red button:
<button id="demoButton" class="btn btn-primary" data-ng-click="openModal()">Click me!</button>
But when the modal is created ModalController is not resolved, and I get $compile:ctreq error:

I tried to debug the code: getControllers() somewhere around 6433 LOC at angular.js is used to search controller: value = value || $element[retrievalMethod]('$' + require + 'Controller');, so I tried to require Modal instead of ModalController (Controller is appended by Angular), but it didn't help. I cannot understand how $element[retrievalMethod] works (stepped into it, but it is to low-level). So, I'm stuck and appreciate any help.
I've created a Plunk, so you can play and see in console what I mean.
Please, checkout updated plunker:
ModalController scope isn't child scope of PageController, so if you need to pass variables to ModalController you should do it through resolving dependencies directly.
In your directive you can set scope as child of ModalController scope, so you can have access to functions defined there instead of requiring ModalController.
I have a directive and a controller according to this (it's from the Angular JS Directives PacktPub book, mostly).
angular.module('myApp',[])
.directive('myIsolatedScopedDirective', function(){
return {
scope : {
'title' : '#msdTitle'
},
link: function ($scope, $element, $attrs) {
$scope.setDirectiveTitle = function (title) {
$scope.title = title;
};
}
};
})
.controller('MyCtrl', function($scope){
$scope.title = "Hello World";
$scope.setAppTitle = function(title){
$scope.title = title;
};
});
<div ng-controller="MyCtrl">
<h2>{{title}}</h2>
<button ng-click="setAppTitle('App 2.0')">Upgrade me!</button>
<div my-isolated-scoped-directive msd-title="I'm a directive within the app {{title}}">
<h4>{{title}}</h4>
<button ng-click="setDirectiveTitle('bob')">Bob it!</button>
</div>
</div>
The problem is the following:
Why the <h4>{{title}}</h4> evaluate to "Hello World" and why not "I'm a directive within the app Hello World"?
Can anybody explain this please?
Thank you.
Plunker
The reason is, you have to enter the template inside directive's template property to make it the isolated one. Right now, the directive creates an isolated scope, but it doesn't use it anywhere, because the content inside your directive tag is already evaluated in the parent scope (of MyCtrl) when the directive's link function is triggered
This is probably what to want to do

.directive('myIsolatedScopedDirective', function(){
return {

$scope.setDirectiveTitle = function (title) {
$scope.title = title;

I want to pass the userName from a list of userNames a logged in user clicks on to twitter bootstrap modal.
I am using grails with angularjs, where data is rendered via angularjs.
Configuration
My grails view page encouragement.gsp is
<div ng-controller="EncouragementController">
<g:render template="encourage/encouragement_modal" />
<tr ng-cloak
ng-repeat="user in result.users">
<td>{{user.userName}}</rd>
<td>
<a class="btn btn-primary span11" href="#encouragementModal" data-toggle="modal">
Encourage
</a>
</td>
</tr>
My encourage/_encouragement_modal.gsp is
<div id="encouragementModal" class="modal hide fade">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"
aria-hidden="true">×</button>
<h3>Confirm encouragement?</h3>
</div>
<div class="modal-body">
Do you really want to encourage <b>{{aModel.userName}}</b>?
</div>
<div class="modal-footer">
<button class="btn btn-info"
ng-click="encourage('${createLink(uri: '/encourage/')}',{{aModel.userName}})">
Confirm
</button>
<button class="btn" data-dismiss="modal" aria-hidden="true">Never Mind</button>
</div>
</div>
So, how can I pass userName to encouragementModal?
To pass the parameter you need to use resolve and inject the items in controller
$scope.Edit = function (Id) {
var modalInstance = $modal.open({
templateUrl: '/app/views/admin/addeditphone.html',
controller: 'EditCtrl',
resolve: {
editId: function () {
return Id;
}
}
});
}
Now if you will use like this:
app.controller('EditCtrl', ['$scope', '$location'
, function ($scope, $location, editId)
in this case editId will be undefined. You need to inject it, like this:
app.controller('EditCtrl', ['$scope', '$location', 'editId'
, function ($scope, $location, editId)
Now it will work smooth, I face the same problem many time, once injected, everything start working!
The other one doesn't work. According to the docs this is the way you should do it.
angular.module('plunker', ['ui.bootstrap']);
var ModalDemoCtrl = function ($scope, $modal) {
var modalInstance = $modal.open({
templateUrl: 'myModalContent.html',
controller: ModalInstanceCtrl,
resolve: {
test: function () {
return 'test variable';
}
}
});
};
var ModalInstanceCtrl = function ($scope, $modalInstance, test) {
$scope.test = test;
};
See plunkr
Alternatively you can create a new scope and pass through params via the scope option
var scope = $rootScope.$new();
scope.params = {editId: $scope.editId};
$modal.open({
scope: scope,
templateUrl: 'template.html',
controller: 'Controller',
});
In your modal controller pass in $scope, you then do not need to pass in and itemsProvider or what ever resolve you named it
modalController = function($scope) {
console.log($scope.params)
}
You can also easily pass parameters to modal controller by added a new property with instance of modal and get it to modal controller.
For example:
Following is my click event on which i want to open modal view.
$scope.openMyModalView = function() {
var modalInstance = $modal.open({
templateUrl: 'app/userDetailView.html',
controller: 'UserDetailCtrl as userDetail'
});
// add your parameter with modal instance
modalInstance.userName = 'xyz';
};
Modal Controller:
angular.module('myApp').controller('UserDetailCtrl', ['$modalInstance',
function ($modalInstance) {
// get your parameter from modal instance
var currentUser = $modalInstance.userName;
// do your work...
}]);
I tried as below.
I called ng-click to angularjs controller on Encourage button,
<tr ng-cloak
ng-repeat="user in result.users">
<td>{{user.userName}}</rd>
<td>
<a class="btn btn-primary span11" ng-click="setUsername({{user.userName}})" href="#encouragementModal" data-toggle="modal">
Encourage
</a>
</td>
</tr>
I set userName of encouragementModal from angularjs controller.
/**
* Encouragement controller for AngularJS
*
* #param $scope
* #param $http
* #param encouragementService
*/
function EncouragementController($scope, $http, encouragementService) {
/**
* set invoice number
*/
$scope.setUsername = function (username) {
$scope.userName = username;
};
}
EncouragementController.$inject = [ '$scope', '$http', 'encouragementService' ];
I provided a place(userName) to get value from angularjs controller on encouragementModal.
<div id="encouragementModal" class="modal hide fade">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"
aria-hidden="true">×</button>
<h3>Confirm encouragement?</h3>
</div>
<div class="modal-body">
Do you really want to encourage <b>{{userName}}</b>?
</div>
<div class="modal-footer">
<button class="btn btn-info"
ng-click="encourage('${createLink(uri: '/encourage/')}',{{userName}})">
Confirm
</button>
<button class="btn" data-dismiss="modal" aria-hidden="true">Never Mind</button>
</div>
</div>
It worked and I saluted myself.
You should really use Angular UI for that needs. Check it out: Angular UI Dialog
In a nutshell, with Angular UI dialog, you can pass variable from a controller to the dialog controller using resolve. Here's your "from" controller:
var d = $dialog.dialog({
backdrop: true,
keyboard: true,
backdropClick: true,
templateUrl: '<url_of_your_template>',
controller: 'MyDialogCtrl',
// Interesting stuff here.
resolve: {
username: 'foo'
}
});
d.open();
And in your dialog controller:
angular.module('mymodule')
.controller('MyDialogCtrl', function ($scope, username) {
// Here, username is 'foo'
$scope.username = username;
}
EDIT: Since the new version of the ui-dialog, the resolve entry becomes:
resolve: { username: function () { return 'foo'; } }
You can simply create a controller funciton and pass your parameters with the $scope object.
$scope.Edit = function (modalParam) {
var modalInstance = $modal.open({
templateUrl: '/app/views/admin/addeditphone.html',
controller: function($scope) {
$scope.modalParam = modalParam;
}
});
}
If you're not using AngularJS UI Bootstrap, here's how I did it.
I created a directive that will hold that entire element of your modal, and recompile the element to inject your scope into it.
angular.module('yourApp', []).
directive('myModal',
['$rootScope','$log','$compile',
function($rootScope, $log, $compile) {
var _scope = null;
var _element = null;
var _onModalShow = function(event) {
_element.after($compile(event.target)(_scope));
};
return {
link: function(scope, element, attributes) {
_scope = scope;
_element = element;
$(element).on('show.bs.modal',_onModalShow);
}
};
}]);
I'm assuming your modal template is inside the scope of your controller, then add directive my-modal to your template. If you saved the clicked user to $scope.aModel, the original template will now work.
Note: The entire scope is now visible to your modal so you can also access $scope.users in it.
<div my-modal id="encouragementModal" class="modal hide fade">
<div class="modal-header">
