I have an Ember helper which is literally defined as this:
<span class="glyphicon glyphicon-info-sign" data-toggle="tooltip" data-placement="right" data-title="{{text}}"></span>
It's used to render a Bootstrap tooltip. It renders the following HTML:
<div id="ember572" class="ember-view">
<span class="glyphicon glyphicon-info-sign" data-toggle="tooltip" data-placement="right"
data-title="<script id='metamorph-35-start' type='text/x-placeholder'></script>
When a project is archived, no new items can be created in it.
<script id='metamorph-35-end' type='text/x-placeholder'></script>"
data-original-title="" title="" aria-describedby="tooltip416856">
</span>
</div>
How can I stop the helper rendering the containing div?
Create a Component with tagName: 'span' instead of <span> in it's template:
Component:
App.TooltipElementComponent = Em.Component.extend({
tagName: 'span',
attributeBindings: ['data-toggle', 'data-placement', 'data-title']
});
Now, you can use following:
{{tooltip-element data-toggle='tooltip' data-placement='right' data-title='When a project is archived, no new items can be created in it.'}}
Which produces following HTML:
<span id="ember257" class="ember-view" data-toggle="tooltip" data-placement="right" data-title="When a project is archived, no new items can be created in it."></span>
Notice you can still use bindings(data-title=text):
{{tooltip-element data-toggle='tooltip' data-placement='right' data-title=text}}

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/
I am generating a button group with a template:
<div class="btn-group">
{{#if allowNew}}
{{#link-to newRoute type="button" class="btn btn-primary"}}<i class="fa fa-plus"></i> {{t generic.add}} {{capitalize singularHuman}}{{/link-to}}
{{/if}}
{{#if allowDeleteAll}}
<button type="button" {{action "destroyAllRecords"}} class="btn btn-danger"><i class="fa fa-trash-o fa-lg"></i> {{t generic.delete_all}} {{capitalize pluralHuman}}</button>
{{/if}}
</div>
Ember is placing <script> nodes inside the button group, I imagine to handle binding, view updates or whatever.
The problem is that bootstrap is relying on CSS rules like
.btn-group>.btn:first-child:not(:last-child):not(.dropdown-toggle)
to finetune the styles. Since the <script> tag is placed before the first <button> or <a> tag, and after the last one, those CSS rules are getting applied where they should not, and instead of having something like this:
I get something like this:
As you can see the stock bootstrap style has rounded corners for the first and last button (the external corners), but my implementation has no such rounded corners.
Is it possible to somehow overcome this problem?
Use an ember view. See https://coderwall.com/p/f1npbg
App.MyView = Ember.CollectionView.extend({
classNames: ['btn-group'],
itemViewClass: Ember.View.extend({
template: Ember.Handlebars.compile("{{view.content.name}}"),
tagName: 'button',
classNames: ['btn']
}),
attributeBindings: ['data-toggle'],
'data-toggle': 'buttons-radio'
});
Considering the following:
Parent template:
{{view App.SomeView id="42" panelClass="default"}}
View template:
<div class="col-md-3 col-sm-6">
<div class="panel panel-{{panelClass}}">
<div class="panel-heading">
<h3 class="panel-title">
{{name}}
</h3>
</div>
<div class="panel-body">
{{description}}
</div>
</div>
</div>
View JS:
App.SomeView = Ember.View.extend({
templateName: 'views/some-view'
});
How can I achieve output HTML where the panel class gets set properly? At the moment it doesn't work because it wants to bind, so it inserts the ember metamorph script tags, instead of just plain text for the panel class.
Also, the template is wrapped in an extra div. How would I modify it so that the ember-view wrapping div is actually the first div in the template (the one with col-md-3 col-sm-6)?
The bind-attr helper exists for that reason. Here's the guide entry.
<div {{bind-attr class=":panel panelClass"}}></div>
Also, not sure if you can use a prefix on panelClass in the template. If might be easier just to use a computed property to add the panel- beforehand.
I'm sorry, I didn't see your second question about the extra div. The guide explains here how to extend the element.
App.SomeView = Ember.View.extend({
classNames: ['col-md-3', 'col-sm-6']
});
I'm trying to combine two ebmer.js examples: Integrating with jQuery UI and the todos example from emberjs.com. I want to have a todo list that is sortable.
Everything went smooth until I got to a point where I wanted to serialize the sortable. For that to work, I need to be able to add an attribute to the sortable items.
this is the template:
{{#collection Todos.TodosListView}}
{{#view Todos.TodoView contentBinding="content" checkedBinding="content.isDone"}}
<label>{{content.title}}</label>
{{/view}}
{{/collection}}
Todos.TodosListView is a CollectionView, similar to the menu in the jQuery UI example. Todos.TodoView is a Checkbox.
This generates the following html:
<div class="ember-view todo-list ui-sortable" id="ember267">
<div class="ember-view" id="ember284">
<input type="checkbox" class="ember-view ember-checkbox todo" id="ember297">
<label>
<script type="text/x-placeholder" id="metamorph-1-start"></script>
something to do
<script type="text/x-placeholder" id="metamorph-1-end"></script>
</label>
</div>
</div>
What I need to be able to do is edit the <div> that wraps the <input>. Assuming the todo's id is 1, I want to add serial=todos_1. I tried to add didInsertElement to TodoView and add an attribute to the parent view, but I didn't have access to the content of the view (the todo itself).
Is this possible?
Thanks for your help.
EDIT:
I found a workaround - adding the ID to the DOM as a hidden element.
The updated template:
{{#collection Todos.TodosListView}}
{{#view Todos.TodoView contentBinding="content" checkedBinding="content.isDone" serial="content.serial"}}
<label>{{content.title}}</label>
<span style="display: none;" class="todo-id">{{content.id}}</span>
{{/view}}
{{/collection}}
Todos.TodoView.didInsertElement:
didInsertElement: function() {
var $div = this.get('parentView').$();
var id = $div.children('.todo-id').text();
$div.attr('serial', 'todos_' + id);
}
Generated html:
<div class="ember-view todo-list ui-sortable" id="ember267">
<div class="ember-view" id="ember284" serial="todos_100">
<input type="checkbox" class="ember-view ember-checkbox todo" id="ember297">
<label>
<script type="text/x-placeholder" id="metamorph-1-start"></script>
something to do
<script type="text/x-placeholder" id="metamorph-1-end"></script>
</label>
<span class="todo-id" style="display: none;">
<script type="text/x-placeholder" id="metamorph-2-start"></script>
100
<script type="text/x-placeholder" id="metamorph-2-end"></script>
</span>
</div>
</div>
I would still like to know if there's a more elegant way of achieving this.
You can create a computed property serial and add this property to the attributeBindings (documented here) of your itemViewClass of Todos.TodosListView, see http://jsfiddle.net/pangratz666/6X4QU/:
Todos.TodosListView = Ember.CollectionView.extend({
itemViewClass: Ember.View.extend({
attributeBindings: ['serial'],
serial: function() {
return 'todos_' + Ember.getPath(this, 'content.id');
}.property('content.id').cacheable()
})
});
