When we use LoadingController in Ionic 3, it takes the fullscreen control.
Is it possible to create loading screen just for an HTML element?
For Example I have 4 cards displayed in a page and each of them will show the loading until the data is loaded. In the mean time, rest of the elements should be available to the user.
I have tried to implement it but can not find help from Ionic 3 Doc
I have tried custom loading with the following code but it did not work. It still takes the full screen.
TS page:
presentLoadingCustom() {
let loading = this.loadingCtrl.create({
spinner: 'hide',
content: `
<div class="custom-spinner-container">
<div class="custom-spinner-box"></div>
</div>`,
duration: 5000
});
loading.onDidDismiss(() => {
console.log('Dismissed loading');
});
loading.present();
}
HTML page:
<div class="custom-spinner-container">
<div class="custom-spinner-box"> My content here...</div>
</div>

original title: VueJS with Bootstrap, stretched link with hidden button
I am trying to make clickable bootstrap cards in a VueJS project, I want clicking the card to open a collapsible element within the card, right now I have something that works using a button with the "stretched-link" class
<b-card
v-bind:img-src="`https://via.placeholder.com/200`"
img-alt="Image"
img-top
tag="article"
style="max-width: 20rem;"
class="mb-2">
<b-button v-b-toggle="'collapse-' + unique-identifier" variant="primary" class="stretched-link ">Toggle</b-button>
<b-collapse v-bind:id="'collapse-' + unique-identifier" class="mt-2">
<b-card>This is the collapsed content</b-card>
</b-collapse>
</b-card>
I'm trying to make this work without having a visible button in the card, I've tried using the invisibile class and the d-none class (class="stretched-link d-none" and class="stretched-link invisible")
In both cases, the button is made invisible but so is the stretched link. Is there any way to maintain the active stretched link area while hiding the button icon?
ok I figured out a solution for my particular use case with JQuery,
What I was really after was a clickable image with the functionality of a bootstrap button. So this is a solution for that problem, not exactly hidden stretched links.
In my Vue component I define the triggerButton method, which finds a button by its id and clicks it.
<script>
import $ from 'jquery'
export default {
props: //just filling this for structure,
data() {
return {
//stuff
}
},
async mounted() {
//more placeholder structure
},
methods: {
//here is the sauce
triggerButton(id) {
$("#"+id).click();
},
}
}
</script>
Then in the <template> body I have a hidden button. "unique-identifier" is just a unique number that is put in, it's needed in my case because im generating many of these elements in a for loop and they need to have distinct ids.
In this case I'm using the bootstrap button to trigger a unique modal.
<b-button style="display:none" v-bind:id="'button'+ unique-identifier" v-b-modal="'modal' + unique-identifier">Launch centered modal</b-button>
Then finally I have an image displayed in the bootstrap card, and on click i call the triggerButton method that will now display my modal.
<img v-on:click="showModal('button' + unique-identifier)" :src="`https://placekitten.com/g/200/200`"/>
I am using primefaces documentViewer which is based on mozilla PDF.js: 2.11.338
https://www.primefaces.org/showcase-ext/views/documentViewer.jsf
and I want to customize the viewer to control which buttons to appear in the toolbar like rotate & print & download only.
I couldn't find any guides about that in primefaces website.
There is no JS Widget for Document Viewer however this can be accomplished easily with a JS function like this.
Note: Some buttons like presentationMode are special and need to be hidden a little differently.
pdfHideButtons : function() {
var pdfViewer = $("#YourDivId");
if (pdfViewer) {
$(pdfViewer.contents().find("#openFile")).hide();
$(pdfViewer.contents().find("#viewBookmark")).hide();
}
}
Then on your page add this code to basically hide the buttons after the page loads.
<script>
$(document).ready(function() {
setTimeout(function(){ pdfHideButtons(); }, 1000);
});
</script>
After over 2h trying to troubleshoot this myself, here I am - a newbie!
Issue: I'm trying to create a MAGNIFIC LIGHTBOX GALLERY (just like the example: http://dimsemenov.com/plugins/magnific-popup/) but when you click on an image, it opens into a new page (so gallery doesn't work - see what's happening life here).
Here's my HTML:
<div class="grid gallery popup-gallery" id="portfolio-grid">
<div class="col-4_sm-6_xs-12">
</div>
<div class="col-4_sm-6_xs-12">
</div>
<div class="col-4_sm-6_xs-12">
</div>
<div class="col-4_sm-6_xs-12">
</div>
</div>
And my Javascript:
$(document).ready(function() {
$('.popup-gallery').each(function() { // the containers for all your galleries
$(this).magnificPopup({
delegate: 'a', // the selector for gallery item
type: 'image',
gallery: {
enabled:true
}
});
});
});
Side notes/Requirements: I'm using Gridlex Flexbox for wrapping images in a grid and it's a dynamic website so images are uploaded via Jekyll.
Any clues?
Thank you!
Using Html2canvas, jsPdf, and angularjs to take a screen shot of a portion of my webpage to show as a pdf preview. I was able to successfully export the content to the pdf, but it only shows half of the content. What can I do to fix this?
Here is the button that creates the pdf. (rollup.html)
<button ng-click="genPDF()">PDF Test</button>
Within the controller, I used the html2canvas function (rollup.js)
Here I believe 'document.body.appendChild' may be the key because when it is uncommented it shows another copy of the table within the webpage when 'pdfTest' is click, as well as within the pdf preview, but only half of the content.
app.controller('Rollup', function($scope, $rootScope, $http, $uibModal, headersvc, locFiltersvc) {
.....
$scope.genPDF = function(){
html2canvas(document.getElementById("testDiv"), {
onrendered: function (canvas) {
//document.body.appendChild(canvas);
var img = canvas.toDataURL("image/png");
var doc = new jsPDF();
doc.addImage(img, 'JPEG',10,10);
doc.save('test.pdf');
//IE 9-11 WORK AROUND
if (navigator.userAgent.indexOf("MSIE ") > 0 ||
navigator.userAgent.match(/Trident.*rv\:11\./))
{
var blob = canvas.msToBlob();
window.navigator.msSaveBlob(blob,'Test file.png');
}
},
//width: 300,
//height: 300
});
}
});
Of course within the html page where the table is created, I have an id of testDiv within the div to the content I want appearing in the pdf.(route.html)
<div class="row" id="testDiv">
....all the table content
</div>
How can I fit the full content to the pdf preview without it cutting off? Any help is greatly appreciated.
Found a solution where I add parameters to the doc.addImage.
doc.addImage(img, 'JPEG',10,10,190,200);
I am not sure how to make the image 100 % of the pdf page, but with this I can set parameters that work best for the table atleast. Hopefully I can find a better solution, but this works for now.
I have an image and when its clicked I want to show some html ( a div with some text and buttons). I know I can use the html config in a window or panel but is it possible to show the element without it being encapsulated in a component?
Here is the code for the image and click handler:
{
xtype:"image",
src:"/blah/helpicon.png",
listeners:{
render: function (c) {
c.getEl().on('click', function(e) {
//show html here, targeted on image icon
}, c);
}
}
}
Here is the html I want to show. All it is really is a fancy tooltip, thats all. And since its a tooltip i dont want to encapsulate it in a window:
<div id="test" class="hopscotch-bubble-container" style="width: 280px; padding: 15px;"><span class="hopscotch-bubble-number">1</span>
<div class="hopscotch-bubble-content"><h3 class="hopscotch-title">Step 1</h3>
<div class="hopscotch-content">Step 1 Instructions here.</div>
</div>
<div class="hopscotch-actions">
<button id="hopscotch-prev" class="hopscotch-nav-button prev hide">Back</button>
<a class="hopscotch-bubble-close" href="#" title="Close">Close</a>
</div>
thanks.
How about making your own Component with your custom html?
Ext.define('mycomponent', {
extend: 'Ext.Component',
cls: 'hopscotch-bubble-container',
width: 280,
padding: 15,
id: 'test',
html: [
'<span class="hopscotch-bubble-number">1</span>',
'<div class="hopscotch-bubble-content"><h3 class="hopscotch-title">Step 1</h3>',
'<div class="hopscotch-content">Step 1 Instructions here.</div>',
'</div>',
'<div class="hopscotch-actions">',
'<button id="hopscotch-prev" class="hopscotch-nav-button prev hide">Back</button>',
'<a class="hopscotch-bubble-close" href="#" title="Close">Close</a>'
]
});
By default a component will use a div to render your element, so by applying the outer html attributes to the component (cls, width, padding, and id) it will generate the outer most div correctly. The inner html is just passed through the html config. Now you can manage your component without having to deal with the html elements directly.
Here is a fiddle with an overly simple example of adding the new component to a container.
