I need some help. I'm new to React and I'm trying to translate app with ReactIntl and FormattedMessage. My question is: "Can I translate content of css pseudo element ::before, that is located in my App.css file?" And if it's possible, how? :-)
.btnAdd::before {
content: "Add";
}
Thanks!
A great way is to use html's lang attribute!
Like this:
html[lang="en"] .btnAdd:before {
content: 'Add';
}
html[lang="pl"] .btnAdd:before {
content: 'Dodaj';
}
html[lang="it"] .btnAdd:before {
content: 'Aggiungi';
}

I'm trying to customize the Quill editor for my needs. I managed to implement and insert custom blots, as described in https://quilljs.com/guides/cloning-medium-with-parchment/ But I need to edit data, which is attached to my blots, like the URL of a link for example. The default implementation of Quill displays a small "inline" edit box for links. I want to implement something like that myself, but just don't get it. I did not find any hints in the docs and guides. Reading the source code of Quill, I was not able to figure out where the editing dialog for links is implemented. Any starting point would be very appreciated.
I've tried something similar. Proper way of doing it should be creating a module. Unfortunately as you already know it is not as easy as it seems.
Let me point you to some useful resources that helped me a lot with understanding how to create extensions for quill.
Quills maintainer is curating Awesome quill list.
I recommend looking especially into
quill-emoji it contains code to display tooltip emoji while writing
quill-form maybe some form extension has some code that will point you in the right direction
Here is my try on to it using custom quill module.
const InlineBlot = Quill.import('blots/inline');
class NamedLinkBlot extends InlineBlot {
static create(value) {
const node = super.create(value);
node.setAttribute('href', value);
node.setAttribute('target', '_blank');
return node;
}
}
NamedLinkBlot.blotName = 'namedlink';
NamedLinkBlot.tagName = 'A';
Quill.register('formats/namedlink', NamedLinkBlot);
const Tooltip = Quill.import('ui/tooltip');
class NamedLinkTooltip extends Tooltip {
show() {
super.show();
this.root.classList.add('ql-editing');
}
}
NamedLinkTooltip.TEMPLATE = [
'<a class="ql-preview" target="_blank" href="about:blank"></a>',
'<input type="text" data-link="https://quilljs.com">',
'Url displayed',
'<input type="text" data-name="Link name">',
'<a class="ql-action"></a>',
'<a class="ql-remove"></a>',
].join('');
const QuillModule = Quill.import('core/module');
class NamedLinkModule extends QuillModule {
constructor(quill, options) {
super(quill, options);
this.tooltip = new NamedLinkTooltip(this.quill, options.bounds);
this.quill.getModule('toolbar').addHandler('namedlink', this.namedLinkHandler.bind(this));
}
namedLinkHandler(value) {
if (value) {
var range = this.quill.getSelection();
if (range == null || range.length === 0) return;
var preview = this.quill.getText(range);
this.tooltip.show();
}
}
}
Quill.register('modules/namedlink', NamedLinkModule);
const quill = new Quill('#editor', {
theme: 'snow',
modules: {
namedlink: {},
toolbar: {
container: [
'bold',
'link',
'namedlink'
]
}
}
});
CodePen Demo
To see the tooltip:
Select any word
Click invisible button on the right of link button, your cursor will turn to hand.
Main issues that need to be addressed:
in order to customize the tooltip you will need to copy majority of the code from SnowTooltip Main pain point is that you cannot easily extend That tooltip.
you need to also adapt the code of event listeners but it should be straightforward
Here's a partial answer. Please see lines 41-64 in file "https://github.com/quilljs/quill/blob/08107187eb039eababf925c8216ee2b7d5166d41/themes/snow.js" (Please note, that the authors have since moved to TypeScript, lines 45-70?, and possibly made other changes.)
I haven't tried implementing something similar but it looks like Quill is watching a "selection-change" event and checks if the selection is on a LinkBlot with a defined link.
The SnowTooltip class includes references to the selectors, 'a.ql-preview', 'ql-editing', 'a.ql-action', and 'a.ql-remove', which we find in the link-editing tooltip.
this.quill.on(
Emitter.events.SELECTION_CHANGE,
(range, oldRange, source) => {
if (range == null) return;
if (range.length === 0 && source === Emitter.sources.USER) {
const [link, offset] = this.quill.scroll.descendant(
LinkBlot,
range.index,
);
if (link != null) {
this.linkRange = new Range(range.index - offset, link.length());
const preview = LinkBlot.formats(link.domNode);
this.preview.textContent = preview;
this.preview.setAttribute('href', preview);
this.show();
this.position(this.quill.getBounds(this.linkRange));
return;
}
} else {
delete this.linkRange;
}
this.hide();
},
);
I'm trying to add a loading spinner. Per the docs for html and meteor, I installed the atmosphere package. Here is my attempt:
renderSpinner() {
Meteor.Spinner.options = {
lines: 13,
...
left: 'auto'
};
var target = document.getElementById('spinner');
var spinner = new Spinner(options).spin(target);
}
And:
render() {
<span id="spinner"></span>
{this.renderSpinner()}
}
But that doesn't produce desired outcome. So I guess my questions are:
How do I import the package into one of my files? (Or I don't need to?)
What is the equivalent of {{> spinner}} in React?
How do I make it work?
Sorry if these questions are very basic, I'm starting out and I bet I'm not the only one!
Ok I'm retarded. The solution is to just have
var options = { lines: 13, ... };
Easy peasy
I want to use Quill with bootstrap.
I need to add class="img-fluid" attribute to image tags in the editor.
I would try changing the selector on your css first:
.ql-snow .ql-editor img {
max-width: 100%;
display: block;
height: auto;
}
/* If your theme is different just change the selector */
If that doesn't work I think you can do it by extending the img embed blot, but it might be overkill.
Here is some sample code that extends the imageBlot, and adds your class to it. It should be fairly easy to adjust if you need something more specific.
class ImageBlot extends BlockEmbed {
static create(value) {
let node = super.create();
node.setAttribute('alt', value.alt);
node.setAttribute('src', value.url);
node.setAttribute('class', "img-fluid");
return node;
}
static value(node) {
return {
alt: node.getAttribute('alt'),
url: node.getAttribute('src')
};
}
}
ImageBlot.blotName = 'image';
ImageBlot.tagName = 'img';
Quill.register(ImageBlot);
You can use this code to add a custom class on each img tag:
var Image = Quill.import('formats/image');
Image.className = 'img-fluid';
Quill.register(Image, true);

How do I convert Deltas to pure HTML? I'm using Quill as a rich text editor, but I'm not sure how I would display the existing Deltas in a HTML context. Creating multiple Quill instances wouldn't be reasonable, but I couldn't come up with anything better yet.
I did my research, and I didn't find any way to do this.
Not very elegant, but this is how I had to do it.
function quillGetHTML(inputDelta) {
var tempCont = document.createElement("div");
(new Quill(tempCont)).setContents(inputDelta);
return tempCont.getElementsByClassName("ql-editor")[0].innerHTML;
}
Obviously this needs quill.js.
I guess you want the HTML inside it. Its fairly simple.
quill.root.innerHTML
If I've understood you correctly, there's a quill thread of discussion here, with the key information you're after.
I've quoted what should be of most value to you below:
Quill has always used Deltas as a more consistent and easier to use (no parsing)
data structure. There's no reason for Quill to reimplement DOM APIs in
addition to this. quill.root.innerHTML or document.querySelector(".ql-editor").innerHTML works just fine (quill.container.firstChild.innerHTML is a bit more brittle as it depends on child ordering) and the previous getHTML implementation did little more than this.
Simple, solution is here:
https://www.scalablepath.com/blog/using-quill-js-build-wysiwyg-editor-website/
The main code is:
console.log(quill.root.innerHTML);
This is a very common confusion when it comes to Quilljs. The thing is you should NOT retrieve your html just to display it. You should render and display your Quill container just the same way you do when it is an editor. This is one of the major advantages to Quilljs and the ONLY thing you need to do is:
$conf.readOnly = true;
This will remove the toolbar and make the content not editable.
I have accomplished it in the backend using php.
My input is json encoded delta and my output is the html string.
here is the code , if it is of any help to you.This function is still to handle lists though and some other formats but you can always extend those in operate function.
function formatAnswer($answer){
$formattedAnswer = '';
$answer = json_decode($answer,true);
foreach($answer['ops'] as $key=>$element){
if(empty($element['insert']['image'])){
$result = $element['insert'];
if(!empty($element['attributes'])){
foreach($element['attributes'] as $key=>$attribute){
$result = operate($result,$key,$attribute);
}
}
}else{
$image = $element['insert']['image'];
// if you are getting the image as url
if(strpos($image,'http://') !== false || strpos($image,'https://') !== false){
$result = "<img src='".$image."' />";
}else{
//if the image is uploaded
//saving the image somewhere and replacing it with its url
$imageUrl = getImageUrl($image);
$result = "<img src='".$imageUrl."' />";
}
}
$formattedAnswer = $formattedAnswer.$result;
}
return nl2br($formattedAnswer);
}
function operate($text,$ops,$attribute){
$operatedText = null;
switch($ops){
case 'bold':
$operatedText = '<strong>'.$text.'</strong>';
break;
case 'italic':
$operatedText = '<i>'.$text.'</i>';
break;
case 'strike':
$operatedText = '<s>'.$text.'</s>';
break;
case 'underline':
$operatedText = '<u>'.$text.'</u>';
break;
case 'link':
$operatedText = ''.$text.'';
break;
default:
$operatedText = $text;
}
return $operatedText;
}
Here's a full function using quill.root.innerHTML, as the others didn't quite cover the complete usage of it:
function quillGetHTML(inputDelta) {
var tempQuill=new Quill(document.createElement("div"));
tempQuill.setContents(inputDelta);
return tempQuill.root.innerHTML;
}
This is just a slight different variation of km6 's answer.
For Quill version 1.3.6, just use:
quill.root.innerHTML;
Try it online: https://jsfiddle.net/Imabot/86dtuhap/
Detailed explaination on my blog
This link if you have to post the Quill HTML content in a form
quill.root.innerHTML on the quill object works perfectly.
$scope.setTerm = function (form) {
var contents = JSON.stringify(quill.root.innerHTML)
$("#note").val(contents)
$scope.main.submitFrm(form)
}
I put together a node package to convert html or plain text to and from a Quill Delta.
My team used it to update our data model to include both Quill's Delta and HTML. This allows us to render on the client without an instance of Quill.
See node-quill-converter.
It features the following functions:
- convertTextToDelta
- convertHtmlToDelta
- convertDeltaToHtml
Behind the scenes it uses an instance of JSDOM. This may make it best suited for migration scripts as performance has not been tested in a typical app request lifecycle.
Try
console.log ( $('.ql-editor').html() );
Here is how I did it, for you Express folks. It seems to have worked very well in conjunction with express-sanitizer.
app.js
import expressSanitizer from 'express-sanitizer'
app.use(expressSanitizer())
app.post('/route', async (req, res) => {
const title = req.body.article.title
const content = req.sanitize(req.body.article.content)
// Do stuff with content
})
new.ejs
<head>
<link href="https://cdn.quilljs.com/1.3.2/quill.snow.css" rel="stylesheet">
</head>
...
<form action="/route" method="POST">
<input type="text" name="article[title]" placeholder="Enter Title">
<div id="editor"></div>
<input type="submit" onclick="return quillContents()" />
</form>
...
<script src="https://cdn.quilljs.com/1.3.2/quill.js"></script>
<script>
const quill = new Quill('#editor', {
theme: 'snow'
})
const quillContents = () => {
const form = document.forms[0]
const editor = document.createElement('input')
editor.type = 'hidden'
editor.name = 'article[content]'
editor.value = document.querySelector('.ql-editor').innerHTML
form.appendChild(editor)
return form.submit()
}
</script>
express-sanitizer (https://www.npmjs.com/package/express-sanitizer)
document.forms (https://developer.mozilla.org/en-US/docs/Web/API/Document/forms)
My view only has one form, so I used document.forms[0], but if you have multiple or may extend your view in the future to have multiple forms, check out the MDN reference.
What we are doing here is creating a hidden form input that we assign the contents of the Quill Div, and then we bootleg the form submit and pass it through our function to finish it off.
Now, to test it, make a post with <script>alert()</script> in it, and you won't have to worry about injection exploits.
That's all there is to it.
Here is a proper way to do it.
var QuillDeltaToHtmlConverter = require('quill-delta-to-html').QuillDeltaToHtmlConverter;
// TypeScript / ES6:
// import { QuillDeltaToHtmlConverter } from 'quill-delta-to-html';
var deltaOps = [
{insert: "Hello\n"},
{insert: "This is colorful", attributes: {color: '#f00'}}
];
var cfg = {};
var converter = new QuillDeltaToHtmlConverter(deltaOps, cfg);
var html = converter.convert();
Refer https://github.com/nozer/quill-delta-to-html
For a jQuery-style solution that allows getting and setting the Quill value I am doing the following:
Quill.prototype.val = function(newVal) {
if (newVal) {
this.container.querySelector('.ql-editor').innerHTML = newVal;
} else {
return this.container.querySelector('.ql-editor').innerHTML;
}
};
let editor = new Quill( ... );
//set the value
editor.val('<h3>My new editor value</h3>');
//get the value
let theValue = editor.val();
quill-render looks like it's what you want. From the docs:
var render = require('quill-render');
render([
{
"attributes": {
"bold": true
},
"insert": "Hi mom"
}
]);
// => '<b>Hi mom</b>'
If you want to render quill using nodejs, there is a package quite simple based on jsdom, usefull to render backside (only one file & last update 18 days from now) render quill delta to html string on server
Just use this clean library to convert from delta from/to text/html
node-quill-converter
example:
const { convertDeltaToHtml } = require('node-quill-converter');
let html = convertDeltaToHtml(delta);
console.log(html) ; // '<p>hello, <strong>world</strong></p>'
I'm trying to best integrate annotorious with angular. The Annotorius library although described, it is particularly difficult to debug. (see what I mean at annotorious.debug.js )
So far, I created my own solution with angular-annotorious (free MIT open source project DISCLAIMER: i'm the maintainer of it.), that offers 2 directives for tag and attribute cases, also a service to access the anno object.
I'm facing problems with dynamic contents, like sliders.
(note that I do know that for ng-src images special treatment may be needed due to the img src cycle)
The annotated images with an unique URL, once recreated in the DOM tree, it does not seem to get annotated once again if we call
anno.makeAnnotatable(img)
To reproduce it, see the colorbox example
(colorbox is a free open source modal library)
Are there any interesting ideas how to integrate/annotate dynamic content that may reappear?
I found the solution, instead of doing a "shutting down" annotorious, we simply call the reset function in the onLoad and onCleanup events which is critical for dynamic content like colorbox or fancybox.
The code for dynamic integration with colorbox looks like this:
$scope.annotateColorbox03 = {
rel: 'img-group-01',
slideshow: false,
open: false,
onComplete: function () {
console.log('03-complete');
var photo = colorboxService.getCurrentPhoto();
if (photo.src) {
console.log('annotateColorbox03 ' + photo.src);
annotoriousService.makeAnnotatable(photo);
var annotations = annotoriousService.getAnnotations(photo.src);
console.log(annotations);
if (annotations && annotations.length > 0) {
annotoriousService.showAnnotations(photo.src);
colorboxService.resize();
}
}
},
onLoad: function () {
console.log('03-onLoad');
annotatableImage();
},
onCleanup: function () {
console.log('03-cleanup');
annotatableImage();
}
};
function annotatableImage() {
var photo = colorboxService.getCurrentPhoto();
if (photo && photo.src) {
//required
annotoriousService.reset(photo.src);
}
}
The working example is now at:
Annotorious in Colorbox Gallery
This example relies on angular-annotorious using the annotoriousService.
