In Laravel 8 / livewire 2.5 / alpinejs 3 application I use "te7a-houdini/laravel-trix": "^2.0.5",
which is warpper for https://github.com/basecamp/trix
and I found that in livewire blade template having :
<div class="p-2 w-full">
<div class="body-content" wire:ignore>
<trix-editor
class="trix-content"
x-ref="trix"
wire:model.debounce.1000ms="form.content"
wire:key="trix-content-unique-key"
></trix-editor>
</div>
<x-jet-input-error for="form.content" class="mt-2"/>
</div>
text entered in trix editor if not applied at form.content var when user clicks on style buttons of trix.
Can it be fixed somehow?
Can I on submit call apply method manually?
Thanks!
Have you tried using wire:model.defer instead of debounce?
Using:
WKpdftohml version 0.12.3.2
PHPwkhtmltopdf version 2.2.0
Chart.JS version 2.5.0
I'm trying to print a line graph using the above libraries. I can reproduce a pdf using the shell command: wkhtmltopdf --javascript-delay 5000 " http://netdna.webdesignerdepot.com/uploads7/easily-create-stunning-animated-charts-with-chart-js/chartjs-demo.html" test2.pdf
So there is no problem with WKhtmltopdf.
The problem is when I do it in my app, using the PHPwkhtmltopdf library. I get a blank page.
From my research these are the things I tried:
Added 'javascript-delay' => 500 to Chart.JS options;
Added animation:{onComplete: function () {window.JSREPORT_READY_TO_START =true} to Chart.JS options;
Added <div style="width:800px;height:200;font-size:10px;"> to the parent div of canvas html tag
Added ctx.canvas.width = 800;ctx.canvas.height = 200; to javascript initialization of the chart.
Well nothing worked. I love Chart.JS and WKhtmltopdf, but if I can't print I'll have to drop one of them. Is there any solution?
This is my php code for the PHPwkhtmltopdf:
public function imprimir ($request, $response)
{
// include_once 'config/constants.php';
// include_once 'resources/auxiliar/helpers.php';
$folha = $_POST['printit'];
$variaveis = explode(',', $folha);
$nomeFicheiro = $variaveis[0];
$printName = substr($nomeFicheiro, 5);
if (isset($variaveis[2])) {
$_SESSION['mesNumero'] = $variaveis[2];
$_SESSION['mes'] = $variaveis[1];
} else {
$mesNumero = 0;
$mes = '';
}
ob_start();
if ($nomeFicheiro == 'printPpiam') {
require ('C:/xampp/htdocs/.../'.$nomeFicheiro.'.php');
} else {
require ('C:/xampp/htdocs/.../'.$nomeFicheiro.'.php');
}
$content = ob_get_clean();
// You can pass a filename, a HTML string, an URL or an options array to the constructor
$pdf = new Pdf($content);
// On some systems you may have to set the path to the wkhtmltopdf executable
$pdf->binary = 'C:/Program Files/wkhtmltopdf/bin/wkhtmltopdf';
$pdf -> setOptions(['orientation' => 'Landscape',
'javascript-delay' => 500,
// 'enable-javascript' => true,
// 'no-stop-slow-scripts' => true]
]);
if (!$pdf->send($printName.'.pdf')) {
throw new Exception('Could not create PDF: '.$pdf->getError());
}
$pdf->send($printName.'.pdf');
}
# Update 1
Made a php file with the page output. Run it in the browser and the graph rendered. When I do it in the console it renders everything except the graph!
How can it be wkhtmltopdf renders the graphics in this page : http://netdna.webdesignerdepot.com/uploads7/easily-create-stunning-animated-charts-with-chart-js/chartjs-demo.html but not my own?!
# Update 2
After Quince's comment, I tried just turning the animations off, but I'm not sure on how to do that. I tried:
$pdf -> setOptions(['orientation' => 'Landscape',
'javascript-delay' => 500,
// 'window-status' => 'myrandomstring ',
'animation' => false,
'debug-javascript',
'no-stop-slow-scripts',
]);
But it fails.
Here's the code that works with wkhtmltopdf version 0.12.5:
chart.html

}
window.onload = function() {

Run:

Found the answer. After I created a separate file, outside the framework, i did some tests again. It rendered the graph in the browser so I tried to use the command tool WKhtmltopdf, and it did not worked, when it did with other examples (see Update #1). So there is something wrong with my php page.
Ran the same tests that I did in the framework, and got the answer for my problem. By introducing a parent div tag width dimensions in the canvas tag it made the graph render in the page.
<div style="width:800px;height:200;">
<canvas id="myChart" style="width:800px;height:200;"></canvas>
</div>
The proposition was found in this site: Github, so thanks laguiz.
Try adding this, as according to this github source
<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-polyfill/7.0.0/polyfill.min.js"></script>
Solved it by downgrading wkhtmltopdf: 0.12.4 > 0.12.2.1
chart.js version seemed to have no influence. I used 2.7.0.
Fixed width and height seem to be required as well.
Edit: Since wkhtmltopdf is dead, I switched to Puppeteer recently.
I was dealing with the same issue using rotativa to export my ASP.NET MVC page with Chart.JS to PDF with no luck.
After a couple of days I finally found a super-easy solution to achieve my goal. What I did is simply to use the .toBase64Image() method of Chart.JS to encode the chart to a base64 string variable in Javascript. Then I saved this string into a model and then on the PDF html page a used tag where i put the base64encoded string to a scr property and the result is great :-)
javascript:
//save Chart as Image
var url_base64 = document.getElementById('myChart').toDataURL('image/png');
//set the string as a value of a hidden element
document.getElementById('base64graph').value = url_base64;
PDF view:
<img style='display:block; width:900px;height:400px;position:relative;margin:auto;text-align:center;' id='base64image'
src='#Model.base64graph' />
I'm trying to improve on the answer by temuri, which is great, but a bit bloated. I ran into the OP's issues (even same WKpdftohml version) and this did the trick for me:
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.8.0/Chart.min.js"></script>
<div style="width: 400px;"><canvas id="canvas"></canvas></div>
<script type="application/javascript">
// wkhtmltopdf 0.12.5 crash fix.
// https://github.com/wkhtmltopdf/wkhtmltopdf/issues/3242#issuecomment-518099192
Function.prototype.bind = Function.prototype.bind || function (thisp) {
const fn = this;
return function () {
return fn.apply(thisp, arguments);
};
};
new Chart(
document.getElementById("canvas"), {
"responsive": false,
"type":"line",
"data":{"labels":["January","February","March","April","May","June","July"],"datasets":[{"label":"My First Dataset","data":[65,59,80,81,56,55,40],"fill":false,"borderColor":"rgb(75, 192, 192)","lineTension":0.1}]},
"options":{}
}
);
</script>
I'm yet to figure out how to get the chart library via ordinary tools like npm, instead of getting it via ajax like here in the first line. Note that this can impact your chart resolution.
I was strugling with that too and you self-answer did not help my case. I am using symfony 3.3 and Chart.js 2 and whatever I did, did not work properly. So I have solved it in a different manner (maybe not a clean one) and I wanted to post it here for inspiration to others.
I needed to export a page, that I was presenting to the user in a browser. In browser, I used Javascript to get picture out of the rendered graph with
animation: {
onComplete: function(animation) {
console.log('done');
var url=document.getElementById("barChartByCountryWeight{{ part }}{{ subsetKey }}").toDataURL();
$.ajax({
url: 'saveChartImages',
type: 'POST',
data: { 'barChartByCountryWeight{{ part }}{{ subsetKey }}': url },
success: function(result) {
console.log(result);
console.log('the request was successfully sent to the server');
},
error: function (request, error) {
console.log(arguments[0]['responseText']);
console.log(" Can't do because: " + error);
}
});
}
}
And on server side I put it in session and in a controller for the PDF export, I have taken the image from session and put the image in the HTML, that is converted to PDF.
Hope that helps.
I have implemented the working code for this issue. You can check out the working code here.
NOTE: For generating pdf you must disable the Chart JS animation or add the option javascript-delay=>1000 to the wkhtmltopdf options.
I have solved this problem when I tried to use Chartjs 1 instead of a new chart js. The reason for this is because laravel snappy uses wkhtmltopdf, which doesn't support css animation, while new chartjs uses css animation.
This github issue shows that.
The solution i found is to use google chart instead. It also uses svg, so you can get high resolution charts.
On this page there is a slider updating a input box with example HTML code. You can also see that same code in the source.
I would like to use this in my application so I transplanted it into my code and converted it to Jade (aka Pug). The source now looks like:
div.row
div.small-10.columns
div.range-slider(data-slider data-options="display_selector: #days-off-count; initial: 28;")
span.range-slider-handle(role="slider" tabindex="0")
span.range-slider-active-segment
div.small-2.columns
input(type="number" id="days-off-count" value="28")
And the resulting html looks like this (after prettifying it):
<div class="row">
<div class="small-10 columns">
<div data-slider data-options="display_selector: #days-off-count; initial: 28;" class="range-slider">
<span role="slider" tabindex="0" class="range-slider-handle"></span>
<span class="range-slider-active-segment"></span>
</div>
</div>
<div class="small-2 columns">
<input type="number" id="days-off-count" value="28">
</div>
</div>
Which is very close that shown on in the docs. However on the resulting page the input box is not updated. If I change the input box to a span like in the
'With Label' example it updates.
span(id="days-off-count" value="28")
becomes
<span id="days-off-count" value="28"></span>
I have the foundation.js and the .slider.js included at the bottom of the page.
In addition, if I manually change the value of the input box via the keyboard the slider will jump to that position, so there is some sort of link there.
The software being used:
Ubuntu 14_04
Chrome
Node v0.10.25
Express 4.14.0
Jade 1.11.0
Foundation v5.5.0
Other things to note:
The page has more than one slider so any javascript solutions need to take this into account.
I think this is a bug (hasOwnProperty instead of hasAttribute #6221) in the version of Foundation (5.5.0) you're using. It seems that while it initially applied only to Firefox, it now applies to Chrome too.
Example with (broken) sliders from 5.5.0: jsfiddle.net/tymothytym/jth99pkw/3
Example with (working) sliders from 5.5.3: jsfiddle.net/tymothytym/tw1we8fk/3
The bug was fixed here: https://github.com/zurb/foundation-sites/commit/896e81f1275eefbbdb84ce4da9004ab059b26d45
Basically, go to foundation.slider.js and change this (line 157):
if (settings.display_selector != '') {
$(settings.display_selector).each(function(){
if (this.hasOwnProperty('value')) { // this is the mistake / bug
$(this).val(value);
} else {
$(this).text(value);
}
});
}
to this:
if (settings.display_selector != '') {
$(settings.display_selector).each(function(){
if (this.hasAttribute('value')) { // this should fix it
$(this).val(value);
} else {
$(this).text(value);
}
});
}
This is not my fix, it's the same as the patch, but it should mean that when you do upgrade you don't need to modify your application code to account for a workaround.
1) Maybe I be wrong... but you didn't specify the version, you give an example from Foundation v5... are you not have installed Foundation v6?
Try this example : https://foundation.zurb.com/sites/docs/slider.html
2) After you include your js files, you need to have this:
<script>
$(document).foundation();
</script>
Edit: Sorry, first time I didn't read all, maybe the problem is that the Foundation use the "value" attribute, which is an attribute designed for <input> tags:
value <button>, <input>, <li>, <option>, <meter>, <progress>, <param> Specifies the value of the element

I have a ul list and a button:
<form>{% csrf_token %}
<div class="list-arrows col-md-1 text-center">
<button class="btn btn-default btn-sm move-left">
<span class="glyphicon glyphicon-chevron-left"></span>
</button>
</div>
</form>
This triggers my ajax request:
function publListChanged()
{
var publs = $('.list-right ul li.active');
Dajaxice.awv_public.reload_stats(Dajax.process, {'publs': '10'})
}
$(function () {
[...]
$('.list-arrows button').click(function () {
var $button = $(this), actives = '';
if ($button.hasClass('move-left')) {
publListChanged();
}
}
}
Currently, for debugging, my method does nothing:
#dajaxice_register
def reload_stats(request, publs):
dajax = Dajax()
return dajax.json()
I get the following error: Dajaxice: Something went wrong. I have no idea where to look. What should I do?
I suspect what went wrong is that you're using the latest version of Django.
Djaxice is a dead project and stopped working after Django 1.6 was released, although the exact version when it broke doesn't appear to be documented. (This inference in this Github issue was the closest I could find to documenting exactly which version broke.)
I once tried upgrading Django in an existing project and found that it broke Djaxice. (This was a while back, so I don't remember what exactly the error was.)
Quoting from the official Github repo: "Should I use django-dajaxice? In a word, No."
Several people have tried to port Djaxice to newer versions of Django, but I've never seen a successful fork. (Maybe a new one was created since I last looked.) I've looked into porting it myself, but found it to be non-trivial.
I'm currently working on a rendering in Sitecore 7.2 (MVC) that will show a jwPlayer given a link to a video (either in the Media Library or from an external source, like YouTube). When I add the rendering (with a valid data source) through Presentation Details in the Content Editor everything looks fine, and works perfectly. The trouble that I'm running into right now, though, is that when I try to do the same thing from the Page Editor (with the exact same rendering and data source), nothing is showing up in that placeholder at all.
The part of the rendering that deals with the video is as follows:
#if (Model.VideoLink != null && Model.Image != null)
{
var vidid = Guid.NewGuid().ToString();
<div class="article-video-module">
<p class="video-placeholder-text">#Html.Raw(Model.Heading)</p>
<div id="#vidid">Loading the player...</div>
<script type="text/javascript">
jwplayer("#vidid").setup({
file: "#Model.VideoLink.Url",
image: "#Model.Image.Src",
width: "100%",
aspectratio: "16:9",
sharing: {
link: "#Model.VideoLink.Url"
},
primary: 'flash'
});
jwplayer('videodiv-#vidid').onPlay(function () {
$(this.container).closest('.fullbleed-video-module').find('.video-placeholder-text').hide();
});
jwplayer('videodiv-#vidid').onPause(function () {
$(this.container).closest('.fullbleed-video-module').find('.video-placeholder-text').show();
});
</script>
</div>
#Editable(a => Model.Description)
}
Other things that might help:
When I comment out everything in the <script> tag above the rendering shows up perfectly.
A reference to jwplayer.js is found on the page (that was my first thought)
Console errors in Javascript:
No suitable players found and fallback enabled on jwplayer.js
Uncaught TypeError: undefined is not a function on jwplayer("#vidid").setup({ and on jwplayer('videodiv-#vidid').onPlay(function () { from above.
How can I get jwPlayer and Page Editor to work nicely with each other?
The issue is that when you add a component through Page Editor, the script is fired before the div <div id="#vidid"> element is added to DOM. Don't ask me why...
The solution is really simple: wrap your javascript code with if condition, checking if the div is already there:
<script type="text/javascript">
if (document.getElementById("#vidid")) {
jwplayer("#vidid").setup({
file: "#Model.VideoLink.Url",
image: "#Model.Image.Src",
width: "100%",
aspectratio: "16:9",
sharing: {
link: "#Model.VideoLink.Url"
},
primary: 'flash'
});
jwplayer('videodiv-#vidid').onPlay(function () {
$(this.container).closest('.fullbleed-video-module').find('.video-placeholder-text').hide();
});
jwplayer('videodiv-#vidid').onPause(function () {
$(this.container).closest('.fullbleed-video-module').find('.video-placeholder-text').show();
});
}
</script>
There is also another issue with your code - Guid can start with number, and this is not a valid id for html elements. You should change your code to:
var vidid = "jwp-" + Guid.NewGuid().ToString();
I wouldn't rule out a conflict with the version of JQuery that the Page Editor uses - this usually messes stuff up. There's a good post here on to overcome the issues.
