Ember and external js scripts - javascript

Ok, i'm a really newbie to Ember JS, but i'm having a play and working my way through things.
So far I'm really liking it, but…
I wanted to use something like: https://github.com/ed-lea/jquery-collagePlus, which created a masonry style layout.
I have create the route, and the navigation to that view, but… how do you apply the effect?
Normally a:
$(window).load(function () {
$('.Collage').collagePlus();
});
would do the job at the bottom of the page, but i'm guessing popping in a:
App.GridRoute = Ember.Route.extend({
afterModel: function(){
$('.Collage').collagePlus();
}
});
Might be better, but that's not working…
any help, pointers on this welcome, be gentle as i'm not understanding it quite yet!
PS. i'm also using bootstrap and bootstrap ember (probably doesn't matter…)

The place to do it it's the View, handling the didInsertElement event. I believe the View it's a good place to isolate any logic related to the DOM.
App.GridView = Ember.Route.extend({
classNames: ['Collage'],
didInsertElement: function(){
this.$().collagePlus();
}
});

Hope it helps!

AngularJS ui view autoscroll not working

I'm using Angular's ui-router but having a problem where when I click on a new view, the page doesn't start at the top but where it was. I set autoscroll to true in my ui-view like what others suggested but it still isn't working. I'm not sure what the reason is for it not working.
<ui-view autoscroll="true" />
The default option is true, maybe there's something preventing the autoscroll from firing, we need more code. Also you can make a custom code that'll work. Something like this
$scope.$on('$routeChangeSuccess', function () {
window.scrollTo(0, 0);
});
As you will see at this other SO Post '$routeChangeSuccess' will not work. You need to change the code to look like this:
$scope.$on('$stateChangeSuccess', function () {
window.scrollTo(0, 0);
});

Jquery plugin in emberjs template

Hi im trying to make a simple feed reader using ember.js and feedek. But so far when I try to place the code for the feed, it not working.
Jquery code for feedek (inside the index template in a script tag):
$('#divRss').FeedEk({
FeedUrl: 'http://vikinglogue.com/feed/',
MaxCount: 100
});
Html Code for template:
<script data-template-name="index" type="text/x-handlebars">
<article style="background-color:#fff;" id="divRss"></article>
</script>
When I run this code in the browser, nothing in the template shows up and I'm not getting any errors. I think the issue is caused by not linking feedek in the template but when I tried it, nothing happened. Thanks, any help is appricated.
To use a jQuery plugin in an Ember app, it's usually best to wrap it in a component:
App.FeedEkComponent = Ember.Component.extend({
tagName: 'article',
didInsertElement: function() {
this.$().FeedEk({
FeedUrl: 'http://vikinglogue.com/feed/',
MaxCount: 100
});
}
});
Then in one of your Handlebars templates,
<p>Your feed:</p>
{{feed-ek}}
I would add to Sam's excellent answer as follows:
Make the component reusable by passing in the url as a property
Don't override didInsertElement hook, instead specify that the function should run on 'didInsertElement' event (see here)

Angular + Semantic UI Form Validations not woking [duplicate]

I have a simple website that implements jQuery in order to create a Slider with some images in the Index.html top banner.
Now, I want to use AngularJS so I'm breaking the HTML code into separate partials.
Header
Footer
Top Banner
If I run the Index.html in the original version (without applying AngularJS patterns) then I can see the slider working perfect.
When applying AngularJS patterns, I moved the top banner HTML to a partial html and then applied ng-view to the div where the top banner is originally located.
var app = angular.module('website', ['ngRoute']);
app.config(function($routeProvider) {
$routeProvider.
when('/about',{templateUrl:'app/partials/about.html'}).
when('/contact',{templateUrl:'app/partials/contact.html'}).
otherwise({redirectTo:'/home',templateUrl:'app/partials/home.html'})
});
When I refresh the page the slider is not working, is rendered as simple html without any jQuery effect, is really a mess.
This partials has some jQuery plugins that usually activates by document.ready. But this event not fire when angular load partial in ng-view. How can i call this event to initialize jQuery plugins?
Any clue how to fix this?
Appreciate any help.
When you specify your routes, you can also specify a controller, so your routes would look like this:
var app = angular.module('website', ['ngRoute']);
app.config(function($routeProvider) {
$routeProvider.
when('/about',{templateUrl:'app/partials/about.html', controller: 'aboutCtrl'}).
when('/contact',{templateUrl:'app/partials/contact.html', controller: 'contactCtrl'}).
otherwise({redirectTo:'/home',templateUrl:'app/partials/home.html', controller: 'homeCtrl'})
});
Now, you can define inside each controller what you want to do, jquery-wise, as part of a function, like this:
angular.module('website').controller('aboutCtrl', ['$scope', function ($scope) {
$scope.load = function() {
// do your $() stuff here
};
//don't forget to call the load function
$scope.load();
}]);
Make sense?
The other provided answers will work, but they are bound to controllers, and therefore not as scalable and reusable.
To do it the real "Angular" way as mentioned in the comments, you should be using a directive. The benefit to this is that you're able to create several instances with the same code, and can pass in attributes to the directive logic to "customize" the directive. Here's a sample of a way I've used it using bxSlider plugin:
JS:
app.directive('slider', ['$rootScope', function($rootScope) {
return {
restrict: 'EA',
templateUrl: '/path/to/template',
link: function(scope, iElement, attrs) {
//attrs references any attributes on the directive element in html
//iElement is the actual DOM element of the directive,
//so you can bind to it with jQuery
$(iElement).bxSlider({
mode: 'fade',
captions: true
});
//OR you could use that to find the element inside that needs the plugin
$(iElement).find('.bx-wrapper').bxSlider({
mode: 'fade',
captions: true
});
}
};
}]);
HTML:
<div slider some-attibute="some-attribute"></div>
And inside your directive template you could have the slider wrapper and slides, which you could build dynamically using ng-repeat bound to scope data.
I'd recommend reading this excellent article by Dan Wahlin about creating custom directives and how to fully harness they're power.
I had the same problem, I was loading some nav links in a ng-include and I have a script file called on my index.html with jquery instructions to make links active and It i not see the included content.
I tried all of the above solutions and for some reasons, none of them worked for me. When the content is not included (straight in the index.html) jquery kicks in fine but once included it stopped recognizing my elements.
So I simply wrapped my instructions in a setTimeout() function and it worked! Maybe it'll work for you too?
setTimeout(function() {
$("nav ul li").click(function() {
$("nav ul li").removeClass('active');
$(this).addClass('active');
});
});
Somehow the setTimeout() manages to load the script AFTER angular is done loading included content.
Happy coding everyone !
A Directive is certainly a good option, but you can also add a controller to any partial, which will perform all tasks (also with jQuery if you want) after the partial is loaded:
Example: partials/menu.html
<div ng-controller="partialMenuCtrl">
...
</div>
I had the same issue, I was running Jquery slick slider in simple html page it was working fine. How it works basically by including the slick.min.js file underneath the jquery.min.js file and then in script tags you need to initialize the plugin with options like e.g.
$('.items').slick({
infinite: true,
slidesToShow: 3,
slidesToScroll: 3
});
now coming back to the issue, when I added Angular JS to my page and made partials of the page and then went back to the browser to check weather the page was working fine or not, the page was working fine except the slider. Then I tried to move those slick.min.js and plugin initialization to the partials, and it worked :)
How it worked I don't know the reason, since I am new to Angular but it worked and I am still wondering the reason.
I know it is an old thread but just for the sake of completion, you can use the following JQuery code. It is called event Delegation.
$("#anyDivOrDocument").on('click', '#targetDiv', function(event) {
event.preventDefault();
alert( 'working' );
});
I bought a html5 template and tried to integrate with my angularJS web app. I encountered the same issue. I solved it using:
Put the code below at where you put your <script src="vendor/61345/js/script.js"></script> code.
<script>
document.write('<script src="vendor/61345/js/script.js"><\/script>');
</script>

Emberjs - Ember conditionals break Jquery. Need simple fix

Handlebar conditionals actually delete the DOM elements inside of the conditionals, JQuery thinks that the newly generated DOM elements, despite their matching ID or class is something entirely different.
I need a simple solution for this. A solution that I can wrap my solutions in once per page. I don't want to have to tack .observes() after everything as that seems like a shoddy work-around
Right now I put my Jquery in the didInsertElement{} in my current view that is being used.
Simple Example:
exampleView -
didInsertElement {
$('#exampleButton').on('click', function() {
console.log('To Ember. Or to Angular. That is the question.')
}
}
example.hbs -
{{#if booleanTrue}}
<button id="exampleButton">Button go!</button>
{{/if}}
That approach is not best for Ember. For the future release of Ember they are planing to remove jQuery dependency. With Ember you don't have to use jQuery.
rewrite your code like this:
didInsertElement: function(){
this.$().hide().fadeIn('slow'); // or any animation that you want
},
actions: {
myButtonAction: function(){
//do something
}
}
{{#if booleanTrue}}
<button id="exampleButton" {{action "myButtonAction"}}>Button go!</button>
{{/if}}
willDestroyElement is not right hook for animation. So you have to trigger it yourself.
I use my custom action like
actions: {
deleteClicked: function(){
var self = this;
this.$().animate({ height: 'toggle' }, 300, function() {
self.set('booleanTrue', false);
});
}
}
due to your comment I changed my answer

How to create a subnav in ember.js

This issue has been stumping me for days. I need a subnav to display under the main nav in the application template when a user visits the 'about' page. I feel like I must be missing some vital concept because I keep reading that if something is extremely hard to do in Ember than you're probably doing it wrong. And I feel like Ember should be able to handle a simple subnav with ease.
I would like the subnav to display on the skinny white horizontal bar below the main nav when "ABOUT" is clicked.
I can't put the subnav in the about template since the nav code is in the application template.
My Router:
App.Router.map(function() {
this.resource("about", function() {
this.route("philosophy");
this.route("leadership");
this.route("staff");
this.route("affiliations");
});
this.route("conditions");
this.route("programs");
this.route("testimonials");
});
I can't render a partial inside the application template because I only want it displayed when someone is at the /about url.
I've tried plain old jQuery show and hide with this:
App.ApplicationController = Ember.ObjectController.extend({
currentRouteChanged: function() {
if(this.get('currentRouteName').indexOf('about') > -1) {
$("ul").removeClass("sub-nav-list-hide");
$("ul").addClass("sub-nav-list-show");
}
}.observes('currentRouteName')
});
And it works when you click about, but when you hit the back button or navigate to another page the subnav doesn't hide.
I'm stuck and I feel like I'm making this way too difficult.
I would set a property in the application controller from within App.AboutRoute
App.AboutRoute = Ember.Route.extend({
activate: function(){
this.controllerFor('application').set('renderAboutSubNav', true);
},
deactivate: function(){
this.controllerFor('application').set('renderAboutSubNav', false);
}
});
and then check the property in the application template.
{{#if renderAboutSubNav}}
{{render 'about/subnav'}}
{{/if}}
Here is an example jsbin
That looks elegant to me!
We can do in application controller something similar.
App.ApplicationController=Ember.Controller.extend({
renderAboutSubNav:function(){
var reg = new RegExp("^about\.");
return reg.test(this.get('currentPath'));
}.property('currentPath')
});
