Kendo UI and angular - no widget in $scope - angularjs

I'm using Kendo UI version 2014.2.716 with AngularJS version 1.2.27, and I made a grid using a directive
<div ng-controller="MyController as ctrl">
<div id="myGrid" kendo-grid k-options="{some options}"></div>
<button ng-click="ctrl.doSomething()"></div>
</div>
I read that if you give a name to the grid (like this: kendo-grid="myGridOnScope"), you can access the widget in the controller scope in this way:
myModule.controller('MyController', function($scope) {
this.doSomething = function() {
console.log($scope.myGridOnScope);
}
}
The console.log should log a widget object, but in my case it's undefined. What am I doing wrong? Thanks for the help

I have found out the problem myself, so I'm going to post an answer if someone has the same problem. If you use the controllerAs syntax in AngularJS, you can't just write the name of the widget - you have to prefix it with your controller alias.
Take a look at this example:
<div ng-controller="MyController as ctrl">
<div kendo-grid="myGridName"></div>
</div>
This will not give you the grid object on the $scope - for that you need to add the ctrl prefix:
<div ng-controller="MyController as ctrl">
<div kendo-grid="ctrl.myGridName"></div>
</div>
Now you have access to the widget in your controller like this:
angular.module('MyModule',['kendo.directives'])
.controller('MyController', function($scope){
// this gives you the widget object
console.log(this.myGridName);
// however, this doesn't work
console.log($scope.myGridName);
});
I hope I helped someone with this post.
Cheers,

Try waiting for the event that Kendo emits.
Html
<div kendo-grid="grid" options="gridOptions"></div>
Javascript
$scope.$on("kendoWidgetCreated", function(event, widget){
if (widget === $scope.grid) {
console.log($scope.grid);
}
});
Edit: See this Plunker

It is because angular is too fast and the kendo element doesn't exist when you try to set the options.
I solved this with a watch.
This is my html code:
<div kendo-grid="ListDesign"></div>
And this is my angular code
$scope.$watch('ListDesign', function () {
if ($scope.ListDesign != undefined) {
var gridOptions = {
columns: columns,
sortable: {
mode: 'multiple',
allowUnsort: true
}
};
$scope.ListDesign.setOptions(gridOptions);
$scope.ListDesign.setDataSource(dataSource);
}
});
Does this answer your question?

Trigger ng-submit on ng-click

I am following this answer (and this fiddle) on how to accomplish this.
View:
<section>
<form style="display: none" id="addFriendForm" name="vm.form.addFriendForm" class="form-horizontal" submit-on="submitAddFriendForm" ng-submit="vm.save(vm.form.addFriendForm.$valid)" novalidate>
<input ng-model="vm.userInput" required>
</form>
<div class="list-group">
<a ng-repeat="user in vm.users" ng-click="vm.triggerSubmit(user)" class="list-group-item">
...
</a>
</div>
</section>
Directive:
function submitOn() {
return {
link: function postLink(scope, element, attrs) {
scope.$on(attrs.submitOn, function() {
setTimeout(function() {
// Error:
element.trigger('submit');
});
});
}
};
}
Controller: (triggerSubmit)
// Trigger submit of the form
function triggerSubmit(user) {
vm.userInput = user;
$scope.$broadcast('submitAddFriendForm');
}
When walking through this, I get the error:
TypeError: element.trigger is not a function
...on the line highlighted in the directive. Looking at docs, this seems correct. What's the reason for it failing?
ANSWER:
(if a jQuery answer is wanted, look at the answer below)
A pure angular way of doing it is:
angular.element(element).triggerHandler('submit');
Looks like trigger is not a part of JQLite which ships with angular.
You might have to load JQuery before loading angular.
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.min.js"></script>
OR
As part of your build pipeline (grunt/gulp/webpack etc)
See the other answer for a jQuery approach. For a pure angular approach I used:
angular.element(element).triggerHandler('submit');

Why is my ng-if not working? It's not hiding the div

In my Angular app, I want a certain div to appear if a variable is true, and to disappear if it is false.
However, it is not working. See my Fiddle
Can anyone help me understand why?
HTML
<div ng-controller="MyCtrl">
<div id="newProjectButton" class="project" ng-click="newProjectActive()" ng-if="!creatingNew">
<h1> + </h1>
<h3> New Project </h3>
</div>
<div id="newProjectActive" class="project" ng-if="creatingNew">
<form>
<input name="name" ng-model="newProjectName" type="text"></input>
<button ng-click="newProject()" type="submit" class='btn btn-primary'>Save</button>
</form>
</div>
</div>
JS
var myApp = angular.module('myApp', []);
function MyCtrl($scope) {
$scope.name = 'Superhero';
$scope.creatingNew = false;
$scope.newProjectActive = function () {
$scope.creatingNew = true;
}
$scope.newProject = function () {
alert($scope.newProjectName);
}
}
your angular version is 1.0.1. directive ng-if is not in this version of angular.
its introduce in angular 1.1.5
check this article
and
check it in angular under Directives topic change log
AngularJS first added the ngIf directive in 1.1.5
please update the angular version
here is the Demo
your controller should be like
myApp.controller("MyCtrl" , function($scope) {
because the global controllers are not supported by default in angular 1.3... check this one
First, when I looked at your fiddle, there was older version of your example there,
Second, which actually may be a reason, is in that example you were using angular in version 1.0.1, and i believe that version didn't implement ng-if. Updating to latest version will fix your problem

Angular JS with jquery masonry

I need to use angular and masonry and also implement sorting and filtering.
The fiddle here does use the masonry with Angular and has filtering and sorting working, however the layout does not seem like masonry. I do not think the masonry layout is applied at all.
http://jsfiddle.net/rdikshit/6swek/3/
<div ng-app="test">
<div ng-controller="MainCtrl">
<input type="text" ng-model="nameFilter" />
Order by id
Order by name
Order by age
<div class="items" masonry >
<div ng-repeat="item in items | filter: { name: nameFilter } | orderBy: order:reverse" class={{item.style}}>
<span>{{item.name}}</span>
<span>id: {{item.id}}</span>
<br /> <span>Age: {{item.age}}</span>
<br /> <span>Style: {{item.style}}</span>
</div>
</div>
</div>
</div>
Here is another fiddle with Passy's directive:
http://jsfiddle.net/rdikshit/6swek/5/
STill does nt work. Even the sorting and filtering are not working now.
I modified your JSFiddle and got it to work. Since columnWidth is not specified, the width of the first element is used. That's why there is gap between the elements sometimes
Few points to look out for:
Don't save the Masonry instance, since you are using the JQuery version. To access Masonry methods, simply get the container element then do container.masonry( 'methodName', arguments );
The watches in the controller are not ideal, in a real app you probably want to put them into a directive
The technique where you watch the number of children in the Masonry container doesn't work when you have ngAnimate as one of your dependency. It cause the DOM tree to be updated after $digest(), which make $watch miss
I am working on a simular project, but i am using Isotope with a mansory style.
here is the way i am using it:
Directive:
app.directive('isotope', function ($timeout) {
return {
scope: {
items: '=isotope'
},
templateUrl: 'social-item.html',
link: function (scope, element, attrs) {
var options = {
animationEngine : 'jquery',
itemSelector: '.social-item',
layoutMode: 'masonry',
masonry : {
"gutter": 10,
"isFitWidth": true
}
};
element.isotope(options);
scope.$watch('items', function() {
$timeout(function() {
element.isotope( 'reloadItems' ).isotope();
});
},true);
}
};
});
Directive template (social-item.html):
<div class="social-item" ng-repeat="item in items track by $index">
<!--
Do something with item, in your case something like this:
<span>{{item.name}}</span>
<span>id: {{item.id}}</span>
-->
</div>
HTML Markup:
<div class="social-wall-container" isotope="socials.posts">
<!-- repeat posts from directive -->
</div>
For more information about isotope checkout This link
If you decide to use isotope, make sure to include the necesary files located in the JS folder on the github page.

How to bind data using Angular in my case?

I am trying to create a tooltip based from from this post
Angular-UI-Bootstrap custom tooltip/popover with 2-way data-binding
I successfully created the popup but I have trouble delivering the content to my popover.html
I added this to my script.js
var app = angular.module('myApp', ['ui.bootstrap', 'ian.bootstrap']);
app.controller('myCtrl', function ($scope) {
$scope.item = {
title: 'Original Title',
content:'content 1' //newly added item
};
$scope.text = 'Click me';
});
and I want to display it in my popover.html
<div class="popover-content">
{{item.content}}
</div>
It doesn't show anything. Can someone help me about it? thanks a lot!
my plunker
http://plnkr.co/edit/5pBZ9qq79OPl2tGEeYYV?p=preview
Here is your updated working Plunkr
Basically you have to pass the attr iantooltip-content with the binding of the content item, not the raw text, and after in the directive pass in the directive isolate scope options the binding of the content like :
iantooltipContent: '='
Just change the appenToBody variable and you're done.
You should read the docs for more infos about Angular directive :)
You can add the ng-controller in your div and then specify the controller name like so :
<div class="popover-content" ng-controller='myCtrl'>
{{item.content}}
</div>
Before the use cases, the basic syntax to create a custom directive.
For all the code samples in this page I started from the angular-seed template.
Starting from the angular-seed skeleton is quite easy to extract a model to begin to implement custom directives.
<html ngApp="myApp">
...
<div my-first-directive></div>
<script src="lib/angular/angular.js"></script>
<script src="js/app.js"></script>
<script src="js/directives.js"></script>
...
</html>

Using AngularJS, how do I set $scope properties in the controller of the parent page

Thanks for looking.
I have the following markup for a modal which shares the same angular controller as it's parent page:
<!-- START Add Event Video -->
<script type="text/ng-template" id="EventVideo.html">
<div class="event-modal">
<div class="modal-header"><h3>Event Video</h3></div>
<div class="modal-body">
<p>Please enter the URL of either a <strong>YouTube</strong> or <strong>Vimeo</strong> video.</p>
<span ng-if="!Event.VideoUrlIsValid" style='color:#9f9f9f;'>This doesn't look like a valid YouTube or Vimeo Url. Your video may not work.</span>
<div class="row" ng-controller="EventCreateController">
<div pr-form-input span="12" name="videoUrl" ng-model="Event.Item.VideoUrl" placeholder="YouTube or Vimeo URL" isRequired="false" no-asterisk></div>
</div>
</div>
<div class="modal-footer"><button class="btn btn-primary" ng-click="Event.UI.EventVideoModal.Close()">Done</button></div>
</div>
</script>
<!-- END Add Event Video -->
And here is the relevant JavaScript:
EventVideoModal: {
Open: function () {
$scope.EventVideoModal = $modal.open({
templateUrl: 'EventVideo.html',
controller: 'EventCreateController',
scope: $scope
});
},
Close: function () {
$scope.EventVideoModal.close();
}
}
Please note the Event.Item.VideoUrl model reference.
The modal allows a user to set the URL of a video, and the goal is to have that set $scope.Event.Item.VideoUrl in the controller and then close the modal. The parent page and the modal both share the same controller, so I had hoped that this would work.
The modal behavior is fine (opens and closes as it should), but the $scope.Event.Item.VideoUrl property is not getting set.
Any advice is appreciated.
Problem Solved!
Thanks to Bogdan Savluk, I realized that I had a scope inheritance problem. So, removing both the explicit reference to the controller in the modal HTML as well as in the JavaScript constructor, resolved my problem:
<!-- START Add Event Video -->
<script type="text/ng-template" id="EventVideo.html">
<div class="event-modal">
<div class="modal-header"><h3>Event Video</h3></div>
<div class="modal-body">
<p>Please enter the URL of either a <strong>YouTube</strong> or <strong>Vimeo</strong> video.</p>
<span ng-if="!Event.VideoUrlIsValid" style='color:#9f9f9f;'>This doesn't look like a valid YouTube or Vimeo Url. Your video may not work.</span>
<!-- <div class="row" ng-controller="EventCreateController"> <--REMOVE THIS! -->
<div class="row">
<div pr-form-input span="12" name="videoUrl" ng-model="Event.Item.VideoUrl" placeholder="YouTube or Vimeo URL" isRequired="false" no-asterisk></div>
</div>
</div>
<div class="modal-footer"><button class="btn btn-primary" ng-click="Event.UI.EventVideoModal.Close()">Done</button></div>
</div>
</script>
<!-- END Add Event Video -->
And here is the relevant JavaScript:
EventVideoModal: {
Open: function () {
$scope.EventVideoModal = $modal.open({
templateUrl: 'EventVideo.html',
//controller: 'EventCreateController', <--REMOVE THIS!!
scope: $scope
});
},
Close: function () {
$scope.EventVideoModal.close();
}
}
If you are passing scope to $modal.open() than scope for modal would be created as child scope from passed scope... - so you will have access to all properties from it.
But in case when you are passing the same controller to it - that controller would be applied to new scope and will override all properties from parent.
So in general, as I see the only thing you need to do to achieve desired result is to remove controller from configuration passed to $modal.open() or replace it with something that is specific only for that modal.
