I want to change the DIV class base on CLICK action. I am trying to make a floating sidebar like this http://startbootstrap.com/templates/simple-sidebar.html
This demo has only three lines of code for toggle-ing the class.
<script>
$("#menu-toggle").click(function(e) {
e.preventDefault();
$("#wrapper").toggleClass("active");
});
</script>
I want to achive same thing but in ember way. Below is my HTML code:
<div id="wrap">
<div class="pull-left" id="main_menu">
<ul class="list-group">
<li class="list-group-item">{{#link-to "selectImage"}}<h4>Choose Picture</h4>{{/link-to}}</li>
<li class="list-group-item">{{#link-to "message"}}<h4>Write Message</h4>{{/link-to}}</li>
<li class="list-group-item"><h4>Account info</h4></li>
<li class="list-group-item"><h4>Recent Orders</h4></li>
<li class="list-group-item"><h4>How to</h4></li>
<li class="list-group-item"><h4>FAQ</h4></li>
</ul>
</div>
<!-- Begin page content -->
<div class="container" id="page_content">
{{outlet}}
</div>
<!-- End page content -->
</div>
</script>
<script type="text/x-handlebars" id="cards/index">
<h1>
<button class="pull-left btn btn-default" data-target="#main_menu" {{action 'changeClass'}}>
<img src="images/icons/menu_tablet.png" class="main_menu"/>
</button>
</script>
Now I do not know how can I use the action to change the class in WRAP div. I will really appreciate any help regarding this issue.
You can add the action handler within the controller for cards/index
Controller = Ember.ObjectController.extend({
actions: {
changeClass: function() {
// Run logic here
}
}
})

Im used Bootstrap v4-alpha Im added pop over its working, but i need to add popover-content for the on click function its not fire in Ember-js,
how to put onclick function in emebr-js
this is im used onlick event
<li class="list-group-item" onclick={{action `'event'}}>Airport Pickup</li>
This is my code sample
add-newbooking.hbs
<div class="form-group">
<a href="#" data-toggle="popover" data-placement="bottom" data-toggle="popover" title="Bill Category">
<input type="text" class="form-control" id="formGroupExampleInput" placeholder=""></a>
</div>
<title>Bootstrap Example</title>
<!-- loaded popover content -->
<div id="popover-content" style="display: none">
<ul class="list-group custom-popover">
<li class="list-group-item" onclick={{action 'event'}}>Airport Pickup</li>
<li class="list-group-item" >Food and Beverage</li>
<li class="list-group-item">Yoga Class</li>
</ul>
</div>
<script>$(document).ready(function() {
$('[data-toggle="popover"]').popover({
html: true,
content: function() {
return $('#popover-content').html();
}
});
});</script>
add-newbooking.js
import Ember from 'ember';
export default Ember.Component.extend({
actions:{
event: function () {
console.log("ppessssssss")
}
}
});
The guides have a whole section on this
<li class="list-group-item" {{action 'event'}}>Airport Pickup</li>
You could be better off adding a link or button inside the list item though so that the button is focusable etc
adding onclick and action on an element will add both events i.e. DOM events as well as ember events. so always remember to add any one of the events (preferably ember).
I'm new to Ember, I want to add some query DOM manipulation code to the element in the {{#each}} block. So I google it up and found the solution from this guide:
views/products/index.js
import Spinner from 'appkit/utils/someJqueryCode';
Ember.View.reopen({
didInsertElement : function(){
this._super();
Ember.run.scheduleOnce('afterRender', this, this.afterRenderEvent);
},
afterRenderEvent : function(){
// implement this hook in your own subclasses and run your jQuery logic there
}
});
export default Ember.View.extend({
afterRenderEvent: function() {
Spinner();
}
});
templates/products/index.hbs
<div class='panel panel-default products'>
<div class='panel-heading'>
<h2 class='panel-title'>Our Prodcuts</h2>
</div>
<div class='panel-body'>
<ul class='row'>
{{#each}}
<li class='col-md-4'>
<div class='thumbnail'>
<img {{bind-attr src=url alt=alt}} />
</div>
<div class='caption'>
<h3 class='name-me'>{{name}}</h3>
<p>{{description}}</p>
<div class='row no-gutter'>
<div class='col-xs-3'>
<button class='btn btn-primary'>Buy</button>
</div>
</div>
</div>
</li>
{{/each}}
</li>
</div>
</div>
But I seems after the point when afterRenderEvent() is triggered, all the elements in the {{#each}} block hasn't been rendered to the DOM yet, thus, the jQuery code return undefined
What's the right way to do it?
Your view's didInsertElement hook will fire as soon as the application route is rendered, which happens before the index route. You might think that putting it in the index.js file will work, but it's going to just extend the default application view behavior.
You need to create a more focused view that lives within your index.hbs file. One that is only concerned with your spinner jQuery doohickey. That, and an each/else conditional could work nicely here. For example:
{{#each}}
{{#view App.SpinnerDoohickeyView}}
<li class='col-md-4'>
<div class='thumbnail'>
<img {{bind-attr src=url alt=alt}} />
</div>
<div class='caption'>
<h3 class='name-me'>{{name}}</h3>
<p>{{description}}</p>
<div class='row no-gutter'>
<div class='col-xs-3'>
<button class='btn btn-primary'>Buy</button>
</div>
</div>
</div>
</li>
{{/view}}
{{else}}
<li>Empty collection!</li>
{{/each}}
Notice that I've wrapped each list item in its own view. You could wrap the whole ul if you wanted... this is just an example. The idea is that you are only creating views when you have a model.
And now you can define the view, and simply use the didInsertElement hook to work with jQuery:
App.SpinnerDoohickeyView = Ember.View.extend({
didInsertElement: function () {
this.$('li').css('background', 'blue');
}
});
If you have a model to render, jQuery should be able to safely access it this way. Good luck!
Here's some further reading and some code from the Ember folks that looks like what I've shown you here: http://emberjs.com/guides/views/handling-events/
Hi i try to make an simple ember app that's get info form a json file. App is located here:http://www.autoroben.nl/m/. Problem is i need the ember view return back an id (from the li element) which i need for handlebars. so i can pop up car info with the same jsonfile as the car list.
// MODAL
App.OpenModal = Ember.View.extend({
click: function(evt) {
var id = $(".lijst li").attr('id');
alert(id)
$('#modal').addClass('active');
}
});
the template
<script type="text/x-handlebars" id="index">
<header class="bar bar-nav">
<h1 class="title">AUTOROBEN</h1>
</header>
<div class="content">
<ul class="table-view lijst">
{{#each}}
<li class="table-view-cell media" id="{{unbound ID}}">
{{#view App.OpenModal}}
<img src="/wp-content/uploads/{{unbound featured_image.attachment_meta.file}}" class="media-object pull-left" width="80">
{{title}}
<p>{{autoinfo.details.bouwjaar}} | {{autoinfo.details.kmstand}}</p>
{{/view}}
</li>
{{/each}}
</ul>
</div>
<div id="modal" class="modal">
<header class="bar bar-nav">
{{#view App.CloseModal}}
<a class="icon icon-close pull-right nostyle" href="#"></a>
{{/view}}
<h1 class="title">{{title}}</h1>
</header>
<div class="content">
<ul class="table-view">
<li class="table-view-divider">DETAILS</li>
<li class="table-view-cell">bouwjaar: {{autoinfo.details.bouwjaar}}</li>
<li class="table-view-cell">kmstand: {{autoinfo.details.kmstand}}</li>
</ul>
</div>
</div>
</script>
json file:
App.IndexRoute = Ember.Route.extend({
model: function() {
return Ember.$.getJSON('http://www.autoroben.nl/wp-json/posts/?type=autos');
}
});
Views in ember js by default get the parent context as its own context. In your case its the context of an single item in the each helper. You can access the ID from the view using the following code.
App.OpenModal = Ember.View.extend({
tagName: 'li',
classNames: ['table-view-cell', 'media'],
click: function(evt) {
alert(this.get('context.ID'));
$('#modal').addClass('active');
}
});
Here is a working bin.
I have a sub menu that appears only when a menu item in the main menu is selected. What I want to do is save the state of the sub menu so that, when a user selects something in the sub menu, then navigates away in the main menu, that sub menu item should still be selected when they return to the sub menu. But, I'm not sure how to go about it. Any ideas?

When transitioning from the A route, you can inspect the transition object and see where you're going. It is possible to stash the location where you're going (if it is a sub-route of A) and then utilize it again in the redirect hook of the AIndexRoute.
Check out this updated fiddle: http://jsfiddle.net/ahaurw01/Ce5j8/3/
Figured it out. I thought that ember-latest.js pointed at latest production release, it actually points at the beta of beta - canary. The transition object does not contain a handlerInfos object in prod or in beta, only in canary.
i'm learning EmberJS and building a comment section that allows 1 level of sub comments. I have an Ember View listing all the comments, when you click "reply" on a particular comment, it should display a textarea input for a user to write a sub-comment.
In my EmberJS code when you click "reply" it shows the textarea input for all the comments not just the specific one. Any advice would be appreciated :)
// View
App.commentsView = Em.View.create({
templateName: 'commentsTmpl',
showReply: false,
reply: function(e) {
e.view.set('showReply', true);
e.preventDefault();
}
});
App.replyCommentsView = Em.View.extend({
showReplyBinding: 'App.commentsView.showReply'
});
// Template
<script data-template-name="commentsTmpl" type="text/x-handlebars">
</h2>comment</h2>
{{#each App.commentsController}}
<div class="comment-group clearfix">
<div class="comment">
<img class="comment-pic" {{bindAttr src="userPic"}} alt="user pic">
<div class="comment-content">
{{userName}}
<span class="comment-body">{{text}}</span>
<div class="comment-actions clearfix">
<a href="#" {{action "reply"}}>Reply</a>
</div>
</div>
</div>
{{#view App.replyCommentsView}}
{{#if showReply}}
<div class="comment-reply">
<h2>sub-comment</h2>
<textarea class="txt-comment-reply" rows="2" cols="65"></textarea>
</div>
{{/if}}
{{/view}}
</div>
{{/each}}
</script>
Currently you are binding the showReply to App.commentsView which is the whole container. To be make it easy activate single comments, I'd suggest looking into a CollectionView, this way each of your comments will have their own view and you can toggle showReply on an individual comment's view.
Something like this: (Sorry, I haven't tested it)
App.commentsView = Em.View.create({
templateName: 'commentsTmpl'
});
App.CommentView = Em.View.extend({
classNames: "comment-group clearfix".w(),
showReply: false,
reply: function(e) {
e.preventDefault()
this.set("showReply", true)
}
})
// Template
<script data-template-name="commentsTmpl" type="text/x-handlebars">
</h2>comment</h2>
{{#collection contentBinding="App.commentsController" itemViewClass="App.CommentView"}}
<div class="comment">
<img class="comment-pic" {{bindAttr src="content.userPic"}} alt="user pic">
<div class="comment-content">
{{content.userName}}
<span class="comment-body">{{content.text}}</span>
<div class="comment-actions clearfix">
<a href="#" {{action "reply"}}>Reply</a>
</div>
</div>
</div>
{{#if showReply}}
<div class="comment-reply">
<h2>sub-comment</h2>
<textarea class="txt-comment-reply" rows="2" cols="65"></textarea>
</div>
{{/if}}
{{/each}}
</script>
