UPDATE:
Here's a fiddle. It works a little better than my own real app, but still highlights a potential bug (or my misunderstanding). Notice that the "outro" transition doesn't work.
http://jsfiddle.net/k4a81fza/1/
Original:
This is a partial I'm using inside of a parent Ractive:
<script id="session_tpl" type="text/ractive">
<div>
<a href="#" on-tap="showDetail">
{{#if p.project !== null}}
<p intro-outro="fly">
{{project}}
</p>
{{/if}}
</a>
</div>
</script>
Here's how I'm trying to then update the data (which is changed from a different ractive that represents a detail view):
daysRac.set('days[1].sessions[2].project', null);
The <p> tag in in the template successfully disappears, but without the transition. I've tried other transitions and tweaked duration and delay, but it always is just instantly removed.
Ideally I want different outro and intro transitions, which I thought I could achieve with something like this:
daysRac.set(keypathToProject, null, function(){
daysRac.set(keypathToProject, "The New Value");
});
Again, that works to update the project value displayed in the <p>, but without transitions.
Is there a way to accomplish what I'm after?
This is probably a bug, I submitted an issue on GitHub.
The problem is that Ractive updates {{description}} to null before the transition starts. It works correctly if you don't use an expression, i.e. if you change {{#if description !== null}} to {{#if describtion}}.

When wiring together Trix editor content with Livewire, I am stumbling into problems. I believe that the issue is that when Livewire receives content from Trix, the content is swapped out and Trix becomes disabled. Is there a better way?
What I have done, that works, is as follows. At the moment, the page is the redirected to itself in order to reboot Trix (defeating the whole point of Livewire, but it's being used for other things too).
<div>
<input
id="newCommentTextTrixContent"
type="hidden"
wire:model="newCommentText"
>
<trix-editor
id="newCommentTextTrixEditor"
input="newCommentTextTrixContent"
></trix-editor>
<button wire:click="addComment(document.getElementById('newCommentTextTrixEditor').innerHTML)">Add Comment</button>
</div>
I have tried
wire:model on the hidden input -- nothing happens
x-on:trix-change="$set('comment', $event.target.innerHTML) -- this works, but Trix goes grey and ceases to work after the first keypress (reboot problem?)
I'm sure something like the latter is better, but with Trix somehow being rebooted each time. It all seems a bit messy - so the question is, what's the right way to do this?
I got it working. With up to date Livewire and Alpine installations, the code is roughly as follows.
<div wire:ignore>
<trix-editor
class="formatted-content"
x-data
x-on:trix-change="$dispatch('input', event.target.value)"
x-ref="trix"
wire:model.debounce.60s="newCommentText"
wire:key="uniqueKey"
></trix-editor>
</div>
Why does this work?
You need wire:ignore on the parent node, because Trix inserts the toolbar above the text area. wire:ignore stops Livewire from worrying about it and therefore not removing it or messing with it on the next cycle.
You need a wire:key because the DOM moves around a bit, and this helps Livewire to keep track of it.
I propose the long debounce, which is a hack as the .lazy modifier doesn't work well with text. Also, waiting for Ajax on each key press is painful.
The alpine event ensures that Trix events (like bold, italics etc) are still fired
That's it. I use this above to repetitively submit comments onto the end of a comment stream, and everything seems to work fine. Good luck!
Note, I also have CKEditor working similarly, as described here.
As an extension on #Kurucu 's answer, and the comment under it from #Rehan;
This seems to work very well. But when I apply styles like li or bold
it doesnt retain in the wire:model. Ex:
<div>foo<br>bar<br>foobar</div> I applied the Bullets here the tags
are missing. Did you face this issue? – Rehan
To fix the issue of not having an updated value when pressing buttons bold, italic, or quote for example, add the following part to the trix editor (note the x-on:trix-change="$dispatch('input', event.target.value)"):
<div wire:ignore>
<trix-editor
class="formatted-content"
x-data
x-on:trix-change="$dispatch('input', event.target.value)"
wire:model.debounce.1000ms="newCommentText"
wire:key="uniqueKey"
></trix-editor>
</div>
The above option works but wasn't getting the data back from my field, Here's what worked for me with a little tweak using AlpineJS's #entangle.
Below is my working solution:
<div class="mb-2" x-data="{ description: #entangle('description').defer }"
x-init="$watch('description', function (value) {
$refs.trix.editor.loadHTML(value)
var length = $refs.trix.editor.getDocument().toString().length
$refs.trix.editor.setSelectedRange(length - 1)
}
)" wire:ignore>
<label class="form-label">Job Description <span class="text-danger">*</span></label>
#error('description')
<span class="error d-inline-block"><i class="mdi mdi-alert-circle"> </i> {{$message}}</span>
#enderror
<input name="description" id="description" type="hidden" x-model="description">
<div x-on:trix-change.debounce.1000ms="description = $refs.trix.value">
<trix-editor x-ref="trix" input="description" class="overflow-y-scroll"
style="height: 20rem;"></trix-editor>
</div>
</div>
I got it to work by using Trix's built-in events.
<input id="about" name="about" type="hidden" value="{{ $about }}">
<trix-editor input="about" class="wysiwyg-content"></trix-editor>
<script>
var about = document.getElementById("about")
addEventListener("trix-change", function(event) {
console.log(about.getAttribute('value'));
#this.set('about', about.getAttribute('value'))
})
</script>
I actually looking for a good way to play animations on my app context with Blaze.
To be more explicit, I wrote this super simple example:
<template name="global">
<h1>Hi guys!</h1>
{{> foo}}
</template>
<template name="foo">
<h2>I'm a foo!</h2>
<ul>
{{#each elements}}
{{> bar}}
}}
</ul>
<button name="btnAdd">Add new elem</button>
<button name="btnDel">Delete an elem</button>
</template>
<template name="bar">
<li>{{name}}</li>
</template>
Let's assume we got an Iron-router route which render the global Template.
On this particular render (from "navigate") I want each templates to render with fadeIn.
When click on btnAdd button, a new element created. I wish it would render with SlideInLeft effect.
When click on btnDel button, an element is deleted. I wish it would be destroyed with SlideOutRight effect.
When user navigate to another route, I want all template disappear with fadeOut effect.
Every of my attempt so far wouldn't allow me to do this kind of distinction... I couldn't find any package resolving this problem neither.
I'm actually just playing animation by adding/removing Animate.css class (pretty simple to use and good looking!)
To resume, I want a different animation played depending on the source of the rendering.
Does someone had already face this problem?
BONUS QUESTION: Do you know how to chain animations, like:
render global with fadeIn Effect >> then >> render foo with rotateIn Effect >> then >> render every bar with bounceIn effect
For timing, you can use Meteor.setInterval. For example, you can do $('.elementClass').hide('fast') outside setInterval. It will run first and setInterval will run when you want it to.
For the initial effects, you can use:
Template.templateName.onRendered(function(){
$('.elementClass').fadeIn('fast') //note that element is initially hidden (display:none in CSS). you can use effects from jquery and jquery-ui for more effects. You have to add jquery-ui additionally
})
You can also use jQuery in your router.js, using iron:router.
Router.route('/the-url', function() {
this.render('templateName', {
data: function () {
$('.htmlElement').toggle('slide', {direction:'right'}, 200); //note that the element is initially invisible
}
});
}, {
name: 'routeName'
});
Meteor seems to skip CSS transitions when these are triggered through a template helper.
Is there a way to work around this?
Example:
<template name="example-template">
<div class="example {{myhelper}}"></div>
</template>
Then, "myhelper" would get assigned, through a template helper, a classname that triggers a css transition. But, for some reason, the class is applied but skipping the transition.
I assume this conflicts with Meteor's auto-rendering when the template data sources change, but I don't know how to get around it (I'd like to avoid using jquery for this).
CSS transitions after rendering a new template aren't yet supported by Meteor. The reason is that when rendering the template example-template again, the new HTML is just appended to the DOM with the new classname. Since the DOM changes, the transition doesn't happen.
Your best bet is to use the rendered event in combination with a loading classname:
<template name="example-template">
<div class="example loading"></div>
</template>
Template['example-template'].rendered = function() {
// remove the loading classname here, and have that trigger a transition
}
This is supposed to get easier after new Meteor UI lands (see http://www.youtube.com/watch?v=pGQ-ax5cFnk), but until then you can do this with a preserve directive for your template:
HTML:
<template name="example">
<div id="example-div" class="example {{myhelper}}"></div>
</template>
JS:
Template.example.preserve(['#example-div']);
See http://docs.meteor.com/#template_preserve for more info.
I'm using jQuery Mobile (jQM) and Knockout.js (ko) to develop an application. In this application, I need to generate a variable number of buttons that are defined by a constantly updating web service.
So, in my markup, I have:
<div id="answerPage-buttons" data-bind="foreach: buttonsLabels">
<button data-role="button" data-inline="true" data-theme="b" data-bind="text: text, click: $root.submitAnswer" />
</div>
buttonLabels is a list of short strings returned from the web service. It's defined as:
self.buttonLabels = ko.observableArray();
This all works fine when the buttons are not "jQM styled". However, when I style them using:
$("#answerPage-buttons").trigger("create");
problems arise during the update.
The issue seems to be that jQM wraps the buttons in a div (with a sibling span) to make them all nice and mobile looking. However, when the ko applies the updates via the bindings, it only removes the tags, leaving the surrounding stuff, and adds new button tags - which are then also styled by the jQM trigger call.
So, I end up with an ever-growing list of buttons - with only the last set being operational (as the previous ones are gutted by the removal of their button element, but all the styling remains).
I've managed to address this, I think, by placing the following call immediately after the observable is updated:
$("#answerPage-buttons div.ui-btn").remove();
However, my feeling is that there's probably a better approach. Is there?
I found a solution.
If I surround the buttons with a div, it seems to work - e.g.
<div id="answerPage-buttons" data-bind="foreach: buttonsLabels">
<div>
<button data-role="button" data-inline="true" data-theme="b" data-bind="text: text, click: $root.submitAnswer" />
</div>
</div>
I'm guessing this is because the markup added by jQM remains "inside" the markup replicated by ko. Without the div, jQM wraps the button tag, which was the immediate child of the tag that contains the ko foreach binding.
I'm using KML and the GGeoXml object to overlay some shapes on an embedded Google map. The placemarks in the KML file have some custom descriptive information that shows up in the balloons.
<Placemark>
<name />
<description>
<![CDATA[
<div class="MapPopup">
<h6>Concession</h6>
<h4>~Name~</h4>
<p>Description goes here</p>
<a class="Button GoRight FloatRight" href="#"><span></span>View details</a>
</div>
]]>
</description>
<styleUrl>#masterPolyStyle</styleUrl>
...Placemarks go here ...
</Placemark>
So far so good - the popups show up and have the correct text in them. Here's the weird thing: I'm trying to use CSS to format what goes in the popups, and it halfway works.
Specifically:
The <h6> and <h4> elements are rendered using the colors and background images I've specified in my stylesheet.
Everything shows up in Arial, not in the font I've specified in my CSS.
The class names seem to be ignored (e.g. none of the a.Button formatting is applied; if I define a style like the one below, it's ignored.)
div.MapPopup { background:pink; }
Any ideas? I wouldn't have been surprised for the CSS not to work at all, but it's weird that it only partly works.
Update
Here's a screenshot to better illustrate this. I've reproduced the <div class="MapPopup"> markup further down on the page (in yellow), to show how it should be rendered according to my CSS.
As suggested I've gone in with Firebug to see what's going on. It looks like Google is doing two obnoxious things:
It's stripping out all class attributes from my HTML.
It's throwing all kinds of hard-coded styles around.
Here's my HTML along with the first couple of wrappers inserted by Google:
<div style="font-family: Arial,sans-serif; font-size: small;">
<div id="iw_kml">
<div>
<h6>Concession</h6>
<h4>BOIS KASSA 1108000 (Mobola-Mbondo)</h4>
<p>
Description goes here</p>
<a target="_blank"><span />View details </a>
</div>
</div>
</div>
As you can see, my classes (e.g. MapPopup in my first div, Button etc. in the <a> tag) have all been stripped out.
Knowing this I'll be able to work around Google's interference, using !important and targeting the container div for the whole map - still, this is annoying, and unexpectedly clumsy coming from Google.
More related obnoxiousness related to the HTML in a KML <description> block: Any links are given the attribute target="_blank", whether you like it or not. I'm currently exploring ways to undo that, using jQuery, but what a drag. I really don't understand why Google feels the need to tamper with this HTML.
See also this thread on the official Google Group.
I've had similar issues. I don't know how you are implementing your Marker, or if you are using InfoWindow, or .addListener, but they way I have had to get css styling to work inside of the "pop up bubble" (over the Marker) is to use what is called "inline styling." So I have a variable that I pass into InfoWindow. Assuming you have initialized a variable "marker" with some options, and have the "map" instance created, some example code would look like this:
/*start of myHtml2 variable*/
var myHtml2 = "<div style=\"background-color:lightgray\"><div style=\"padding:5px\"><div
style=\"font-size:1.25em\">Some text</div><div>Some more text<br/>
Yet more text<br/></div><table style=\"padding:5px\"><tr><td><img src=\"A lake.jpg\"
width=\"75px\" height=\"50px\"></td><td>More text<br/>Again, more text<br/><div
style=\"font-size:.7em\">Last text</div></td></tr></table></div></div>"
/*end of variable*/
var infowindow2 = new google.maps.InfoWindow({content: myHtml2});
/*mouseover could be 'click', etc.*/
google.maps.event.addListener(marker, 'mouseover', function(){
infowindow2.open(map, marker);
});
I know the css styling code is cumbersome, but I haven't found a way to use complicated css styling inside "the bubble pop up" using css in the head, or from a style sheet There are always conflicts, and some features don't render properly.
My first guess is that you're running into an issue with CSS specificity. There is a good article on it at http://www.smashingmagazine.com/2007/07/27/css-specificity-things-you-should-know/, so if you can include a container element ID, that may help.
Let me know if this doesn't turn out to be the problem and I'll come up with more ideas.
