How to make blueimp gallery textFactory work with an iframe - blueimp

I have followed the documentation here:
https://github.com/blueimp/Gallery
First loaded assets separatedly.
Then created blueimp-gallery-textFactory.js and loaded after core file, before video file, with the following contents:
blueimp.Gallery.prototype.textFactory = function (obj, callback) {
var $element = $('<div>')
.addClass('text-content')
.attr('title', obj.title);
var iframe=$('<iframe>', {
src: obj.href,
frameborder: 0,
height: '100%',
width: '100%',
scrolling: 'no'
});
$element.html(iframe);
callback({
type: 'load',
target: $element[0]
});
return $element[0];
};
So what changes from original example is that I'm not making an ajax request and then running callback, but instead creating an iframe and then running callback.
And also added the aditional css style to the stylesheet:
.blueimp-gallery > .slides > .slide > .text-content {
overflow: auto;
margin: 60px auto;
padding: 0 60px;
max-width: 920px;
text-align: left;
}
The issue I ran into is that the onLoad/complete event would never fire and the slideLoading class will be always on top of the iframe.

I started to look into the videoFactory plugin and youtube one to see what could be wrong.
So I've stole some CSS from the video plugin:
.blueimp-gallery > .slides > .slide > .text-content > iframe {
position: absolute;
top: 100%;
left: 0;
width: 100%;
height: 100%;
border: none;
}
.blueimp-gallery > .slides > .slide > .text-content > iframe {
top: 0;
}
This (helps) but did not solve the problem.
What did solve the problem was taken from blueimp-gallery-video.js and that is running the callback with this setTimeout function.
blueimp.Gallery.prototype.textFactory = function (obj, callback) {
var $element = $('<div>')
.addClass('text-content')
.attr('title', obj.title);
var iframe=$('<iframe>', {
src: obj.href,
frameborder: 0,
height: '100%',
width: '100%',
scrolling: 'no'
});
$element.html(iframe);
// callback({
// type: 'load',
// target: $element[0]
// });
this.setTimeout(callback, [
{
type: 'load',
target: $element[0]
}
]);
return $element[0];
};
This time the problem got solved. I guess with the $.get ajax call from original example there was no need to call setTimeout but with the iframe it was required.

Reinitialize matterjs after page changes in nuxtjs

I have a matterjs instance in my nuxt app that drops items on the floor. Everything works when I visit the page for the first time or do a page refresh. But when I change the pages (routes) inside my app, so I come back to the page with the matterjs instance, the instance is gone. I always have to do a page refresh...
How can I reinitialize matterjs?

Use the activated hook to restart the animation. The code when mounted() is still needed.
I assume the problem is that when you navigate away and you some back the initial animation is finished, but as Nuxt caches some pages they are served from cache and therefore the mounted() hook is not called. This is where the activated() hooks comes in. It's called when a page/component was keept alive and is reactivated.

Flickity Slider Animation and Gsap

The slider I am building have the active slider bigger than the others. I managed to make it work without the animation with flkty.reposition(). However, I am trying now to add the animation where the next slide grows in and the active decrease out. For The animation I am using GSAP.
The issue I am facing is to overwrite the left property with gsap so that it continuous animate. As of now, the left property (controlled by Flickity) does not take into account the final size (controlled by GSAP) of the selected slide.
https://codepen.io/stefanomonteiro/pen/VwzwjLw?editors=0010
As the left property of each slide is controlled by Flickity, we could use margin-left with a minus value as an alternative property to pull the selected slide to the left. I know margin is not a good property to animate but it works in this case without digging too deep into the Flickity core.
Here is the GSAP code:
gsap.to(slides, {
duration: 1,
width: "220px",
height: "336px"
});
gsap.to(selectedSlide, {
duration: 1,
marginLeft: "-248px", // the empty space calculated by newWidth - oldWidth
width: "468px",
height: "630px",
onComplete: () => {
// once all animations have been settled, we reset the margin
gsap.set(selectedSlide, { marginLeft: "" });
// and tell Flickity to update
flkty.resize();
flkty.reposition();
}
});
And the snippets
const animate = () => {
const flkty = Flickity.data(".carousel");
const selectedSlide = flkty.selectedElement;
const slides = flkty.getCellElements();
// remove the selected slides
slides.splice(flkty.selectedIndex, 1);
gsap.to(slides, {
duration: 1,
width: "220px",
height: "336px"
});
gsap.to(selectedSlide, {
duration: 1,
marginLeft: "-248px", // the empty space calculated by newWidth - oldWidth
width: "468px",
height: "630px",
onComplete: () => {
// once all animations have been settled, we reset the margin
gsap.set(selectedSlide, {
marginLeft: ""
});
// and tell Flickity to update
flkty.resize();
flkty.reposition();
}
});
};
new Flickity(".carousel", {
cellAlign: "right",
wrapAround: true,
percentPosition: false,
on: {
ready: () => animate()
}
});
const nextButton = document.querySelector(".flickity-button.next");
nextButton.addEventListener("click", () => animate());
/* external css: flickity.css */
* {
box-sizing: border-box;
}
body {
font-family: sans-serif;
}
.carousel {
background: #EEE;
}
.carousel-cell {
width: 220px;
height: 336px;
margin-right: 20px;
background: #8C8;
border-radius: 5px;
counter-increment: carousel-cell;
}
.carousel-cell.is-selected {
width: 468px;
height: 630px;
z-index: 1;
}
/* cell number */
.carousel-cell:before {
display: block;
text-align: center;
content: counter(carousel-cell);
line-height: 200px;
font-size: 80px;
color: white;
}

<h1>Flickity - wrapAround</h1>
<!-- Flickity HTML init -->
<div class="carousel">
<div class="carousel-cell"></div>
<div class="carousel-cell"></div>
<div class="carousel-cell"></div>
<div class="carousel-cell"></div>
<div class="carousel-cell"></div>
</div>
And the Codepen
You can also notice that we have to wait until the animation is finished until we perform the next click, otherwise, it would mess up the whole process. This is predictable. Hence, I personally will try not to manipulate this Flickity slider for this kind of animation. Just want to give you a solution, anyway.

How to force ECharts charts to a fixed width when printing?

I'm using some echarts in my Vue application with vue-echarts. All charts have :autoresize="true".
My problem is, that if I try to print the page, the width of the charts are set to match the width of the browser. If browser is full screen then some charts get clipped.
CSS:
.echarts {
width: 100%;
min-height: 200px;
}
#media print {
#page { margin: 1cm }
body {
width: 110mm;
height: 297mm;
margin: 25mm 25mm 25mm 25mm;
}
.echarts {width: 600px !important;} /* This does not work! */
}
In the generated DOM there is a container, and inside that another div with the style: position: relative; width: 567px; height: 400px; padding: 0px; margin: 0px; border-width: 0px; cursor: pointer;
Width of the inner container is updated when browser is resized.
Yes, I have faced the same problem. I have also tried before print and after print and call function to redraw the chart but some times its break when Brower gets a zoom out and zoom in.
I say it's not the best solution but it works perfectly.
Solution -
Overwrite the window.print method in mounted.
window.print = function () {
setTimeout(function () {
_print();
}, 500);
};
use flag print_mode for printing.
let self = this;
window.addEventListener('afterprint', function () {
self.print_mode = false;
});
user ref of the chart instance to get base64 data. call getDataURL() to get image data.
chart = echarts.init(chart_dom);
chart_img = chart.getDataURL()
<img v-if="print_mode" class="print-only" :src="chart_img"></img>
so while printing it display image and print and in normal mode, it shows a chart.

Jquery animate function doesn't work: Invalid keyframe value for property left

above is my jquery code. I want every time I click the frog image, it will move to the left 50 pixels. but when I run the code, it keeps saying "Invalid keyframe value for property left: +=50px"
google console
Here's a working example.
$("#clickme").click(function(){
$(this).animate({ "left": "-=50px" }, "slow" );
});
#clickme {

How can I add header and footer in PDF page using phantom-html2pdf

I am unable to find way of adding header and footer in pdf page using phantom-html2pdf with Express and Coffeescript. My code is as follows can you please review it and tell me what I am missing:
pdf = require('phantom-html2pdf')
exports.test_pdf = (req, res) ->
paperSize = {
format: 'A4',
margin: "1cm",
orientation: 'portrait'
header: {
height: "200cm",
contents: '<h1>This is the Header</h1>'
},
}
htmls = '<html><body><h2>PDF CONTENT</h2></body></html>';
options = {
html: htmls,
css: "./public/stylesheets/foundation.css",
paperSize : page.paperSize
}
pdf.convert options, (err, result) ->
if !err
result.toBuffer()
# Using a readable stream
result.toStream()
# Using the temp file path */
result.getTmpPath()
# Using the file writer and callback */
result.toFile("./html/pdf_file.pdf")
else
res.render('index', { title: 'Social Media'})
I have already done some research that to add header and footer, I need to export a paperSize object from a runnings file. https://github.com/bauhausjs/phantom-html2pdf/issues/30
but adding that too could not help me or I am not adding it correctly.
A little help will be much appreciated. Thanks in advance.
module.exports will resolve your problem. After creating the page object for header & footer. you will export the object with module.export.
Here is the sample code
module.exports = {
header: {
height: '3cm', contents: function (page) {
return '<header class="pdf-header" style=" overflow:hidden; font-size: 10px; padding: 10px; margin: 0 -15px; color: #fff; background: none repeat scroll 0 0 #00396f;"><img style="float: left;" alt="" src="../images/logo.jpg"><p> XYZ </p></header>'
}
},
footer: {
height: '3cm', contents: function (page) {
return '<footer class="pdf-footer" style="font-size: 10px; font-weight: bold; color: #000;><p style="margin: 0">Powered by XYZ</p></footer>'
}
},
}
Note: You need to create runing file and copy & paste given code in it.
