I am trying to understand how the integration between jQueryUI and Emberjs should be done. I am new to both libs and to javascript so this might be a newbie question.
I have this jsfiddle set up: http://jsfiddle.net/pSKgV/1/ and it renders this resulting document:
<body class="ember-application">
<div id="ember129" class="ember-view">
<div id="ember163" class="ember-view ui-draggable"></div>
</div>
</body>
The code is mostly taken from this blog post: http://www.lukemelia.com/blog/archives/2012/03/10/using-ember-js-with-jquery-ui/
Questions: How do I put something inside the inner div? I want to put some content that i can bind to something.
I have tried the following:
{{view App.Draggable}}Drag Me{{/view}} but that gives an error. I’ve also tried
adding this to the App.Draggable object:
didInsertElement: function() {
this.$().html(“Drag Me”)
}
but that did not give the expected results. How is the best way to use/access the jquery/jqueryui functions such as .html() in this situation?
Also, is the outer div necessary or can I make this view only render one div element?
regards

You forget the # symbol {{#view App.Draggable}}Drag me{{/view}}. You should also create namespaces in Ember using Ember.Namespace.create() instead of just using an empty {}

I am trying to add Vue.js components to a Ruby-on-Rails app with SSR support by using Hypernova and vueonrails helpers.
I am able to render a registered component with Hypernova from a view (.html.erb) by using this helper:
<%= render_vue_component('HelloWorld', message: 'Hello World from SSR!') %>
Let's say my HelloWorld component has a <slot> in its template:
<template>
<div class="helloworld">
<h1>{{ message }}</div>
<slot></slot>
</div>
</template>
I want to replicate something like the following in the .html.erb using render_vue_component:
<hello-world message="Hello World from SSR!">
<hello-world>SSR Nested component</hello-world>
</hello-world>
How could I pass child elements to the render_vue_component helper so they get rendered by Hypernova?
Well, I analyzed the repo and by looking at the it, I think you should use the render_vue_component only for rendering the root component, like the main.js when you start a project with #vue/cli:
<%= render_vue_component('App', { router }) %>
I came to this conclusion by analyzing the vueonrails source code.
If you look to the render_vue_component function, it only takes the identifier and a data object, which internally calls render_react_component.
By this signature, it simply don't fit with Vue's render function signatures, which are (element, children) or (element, attributes, children).
Maybe you find a better support by opening an issue on the repo.
But I'd think twice before using this project because there isn't any documentation so far and checking the website, seems like they are more focused in selling books about the project than creating a documentation.
A question similar to this has been posted several time, but I cannot find a solution that works. Hopefully, someone can help!
I am using jQuery Mobile 1.1 and jQuery 1.7.2, so I'm on the most recent stable releases. I want to create a dynamic page header. Using this HTML code, it works fine:
<div data-role="page" id="levela">
<div data-role="header" id="hdr_levela">
<h1>Title</h1>
</div>
</div>
So I then go to dynamically create the title. I change the HTML to this:
<div data-role="page" id="levela">
<div data-role="header" id="hdr_levela">
</div>
</div>
And added the following jQuery code:
// Set the header
var dirHeader = $('#hdr_levela');
dirHeader.append('<h1>' + title+ '</h1>');
The title appears, but is not styled. I have found several posts about this. In the jQuery Mobile Documentation, it says:
"However, if you generate new markup client-side or load in content via Ajax and inject it into a page, you can trigger the create event to handle the auto-initialization for all the plugins contained within the new markup. This can be triggered on any element (even the page div itself), saving you the task of manually initializing each plugin (listview button, select, etc.).
For example, if a block of HTML markup (say a login form) was loaded in through Ajax, trigger the create event to automatically transform all the widgets it contains (inputs and buttons in this case) into the enhanced versions. The code for this scenario would be:
$( ...new markup that contains widgets... ).appendTo( ".ui-page" ).trigger( "create" );
So I tried several things. After the above code, I added the following:
dirHeader.trigger("create");
This had no effect. So I tried to put it on the actual append itself:
dirHeader.append('<h1>' + folderName + '</h1>').trigger("create");
This had no effect. I then tried the process on the parent element (in this case, the id of the parent div is "levela"). So I tried this:
$('#levela').trigger("create");
This also had no effect. At this point, I am completely lost. Every solution involves doing one of the things I have tried and is just not working. I must be missing something incredibly basic but I just can't seem to find it.
Thanks in advance for your help!
You can update the content by calling .page:
See this working Fiddle Example!
// Set the header
var title = 'super hyper BuBu',
$dirHeader = $('#hdr_levela');
$dirHeader.append('<h1>' + title+ '</h1>').page();
I just solved a similar problem -- it appears that jQM headers and footers do not have the "create" method, so as far as I can tell, the css classes and roles need to be added manually.
For reference, I posted an example fix on this (old) question: JQuery Mobile trigger('create') command not working
I've been trying to get a Dojo (1.6) dijit.Tooltip to work when defined in a wijit template.
So, if I have wijit template that includes the following:
<a data-dojo-attach-point="tooltipMe" href="" onclick="return false;">
Show a Tooltip
</a>
<div data-dojo-type="dijit.Tooltip" data-dojo-props="connectId:'tooltipMe'">
Got to love hovering over links. Sometimes you a get a free tooltip
</div>
I can see the link of course, but nothing happens when I hover. Scouting round the newsgroups it seems there might be a problem with defining tooltips in wijit templates, but it's not mentioned in the Dojo docs.
Is it possible to define tooltips inline like this? Or am I just doing something wrong, it seems like the obvious place to do it.
If not, is there an accepted approach for creating and linking tooltips to DOM nodes defined in wijit templates?
Tooltips connectId property has to be the id of a DOM node. data-dojo-attach-point is not an id, it just creates a reference in the instantiated widget.
So in your case you need to assign an id to the a-node and use the same id in connectId. To avoid id clashes when creating multiple instances of your widget you can use the ${id} variable substitution to ensure that all ids are unique:
Your code should look something like this:
<a id="${id}_link" data-dojo-attach-point="tooltipMe" href="" onclick="return false;">
Show a Tooltip
</a>
<div data-dojo-type="dijit.Tooltip" data-dojo-props="connectId:'${id}_link'">
Got to love hovering over links. Sometimes you a get a free tooltip
</div>
I've had problems doing it this way before. I used script to create them on my page after I had done some other work, maybe something like this will help you out if you use it in the template postCreate method.
var span = dojo.query('.hasEntry span').forEach(function(node, index, nodelist)
{
new dijit.Tooltip({
connectId:node,
position:"above",
label: toolTipLabel
});
});
Responding to an old thread here, but just wanted to share a solution for people looking to use tooltips without IDs on their custom widget elements. It's not as pretty as just using tooltip, but it works. It uses the "dijit/popup" and "dijit/TooltipDialog" modules.
this.editTooltipDialog = new TooltipDialog({
content: "<p>I love tooltips</p>",
onMouseLeave: function(){
popup.close(this.editTooltipDialog);
}
});
on(this.targetDiv, 'mouseover', lang.hitch(this, function(){
popup.open({
popup: this.editTooltipDialog,
around: this.targetDiv
});
}));
I tried to replicate the issue in jsFiddle: http://jsfiddle.net/phusick/EcLLb/.
I found out that dijit.Tooltip widget from the template is instantized, but it does not connect mouse events, presumably because DOM node it attempts to connect to does not exist yet (i.e. has not been added to document DOM tree).
To prove the aforementioned I tried to connect the tooltip in widget's postCreate method, when all DOM building is done and it worked:
postCreate: function() {
this.inherited(arguments);
this.tooltip1.set("connectId", this.tooltipMe); // w/o this the tooltip won't show
}
So you can instantize tooltips via a template markup and then just connect then to DOM nodes in postCreate method.
I am trying to create a JQuery UI Accordion, but with the HTML within an accordion being generated by some jQuery code.
I also have some example accordion items in the base HTML; these are working fine.
The problem is that the (sample 1)
$(function(){
$("#accordion").accordion({
event: "click hoverintent"
});
});
code puts accordion-specific class, role etc. tags into the
<div id="accordion">
<h3>Heading</h3>
<div>
<p>
Stuff
</p>
</div>
...
tags, but these are not being inserted into the HTML code I generated with jQuery.
The items above '...' are working fine.
Similar tags generated by jQuery below the '...' do not work, as they don't receive the accordion tags.
I guess the problem lies in when to call the (sample 1) code, so that it is executed after my HTML has been generated. At present it is in the head of my page, as with the accordion examples. I have tried it in other places, and also tried but without success.
Any suggestions, please?
You need to destroy then recreate the accordion for it to be able to work with appended items.
Here is a demo
I'm working on a site that has a dynamically generated FAQ and I'm trying to get nested accordions working. The problem is, only the first collection of questions take on the ui-accordion class.
Here's my code:
http://jsfiddle.net/SmFdt/
(I just copied the source of the page and stripped out most of the text)
What am I doing wrong?
You've got the same id assigned to multiple divs. Try the following instead:
HTML
<h1>Frequently Asked Questions</h1>
<div id="faqs-container" class="accordian">
<h3>One</h3>
<div class="accordian">
<h3>A</h3>
<div>AAAAAAAAAA</div>
<h3>B</h3>
<div>BBBBBBBBBB</div>
</div>
<h3>Two</h3>
<div class="accordian">
<h3>A2</h3>
<div>AAAAAAAAAA2</div>
<h3>B2</h3>
<div>BBBBBBBBBB2</div>
</div>
</div>
JavaScript
$("div.accordian").accordion({
autoHeight: false,
collapsible: true,
active: false
});
Link to example: http://jsfiddle.net/SmFdt/1/
Try this http://jsfiddle.net/SmFdt/3/
The reason it was not working was you were using the same id for multiple divs. I have changed the ids to classes.
On a side note, you have lot of code to display the accordion. You may possibly want to consider reducing some code. (e.g. no need of <p> inside <div>. You can control the spacing using CSS margin and padding properties.)
