I want to manage the content of the page from a content editor where I am getting page content from the API.
Check this screenshot.
I used two different react modules for this react-html-parser and react-string-replace but it is still not working.
Here is my code.
let pageData = '';
pageData = ReactHtmlParser(page.content);
// replacing contact us form with a contact us form component
pageData = reactStringReplace(pageData, '{CONTACT_US_FORM}', (match, i) => (
<ContactUsForm />
));
return <div>{pageData}</div>;
react-html-parser -> It is used to parse HTML tags which are in string format into tree of elements.
react-string-replace -> It is used to replace a string into react a component.
Note: If I use react-html-parser or react-string-replace individually then it works fine but it does not work together.
Any suggestion?
Depends on the expected structure of page.content. If it contains HTML you are right in using react-html-parser, which has a replace option.
import parse from 'html-react-parser';
const macro = '{CONTACT_US_FORM}';
const replaceContactUsForm = (domhandlerNode) => {
if (domhandlerNode.type === 'text' && domhandlerNode.data.includes(macro))
return <ContactUsForm />;
};
// ...
const elements = parse(page.content, { replace: replaceContactUsForm });
return <div>{elements}</div>;
Additionally, If the string {CONTACT_US_FORM} is embedded in text you could use react-string-replace to keep the rest of the text intact:
const replaceContactUsForm = (domhandlerNode) => {
if (domhandlerNode.type === 'text' && domhandlerNode.data.includes(macro))
return <>{reactStringReplace(domhandlerNode.data, macro, () => (<ContactUsForm />))}</>;
};
If page.content does not contain HTML you do not need react-html-parser. But judging from your screenshot some markup is probably contained.
Elementor Pro has a new widget, video playlist. It appends a parameter to the URL, like so: http://aaronpenton.net/ampcreative/vip/about-vip/?playlist=f68425e&video=b8a9967
This is obviously terrible for SEO and UX. Is there a way to remove the ?playlist=f68425e&video=b8a9967 ?
My brother help me with the next script.
Put a "HTML Elementor Widget" with the following:
<script>
function getURLParameter(name) {
return decodeURI((RegExp(name + '=' + '(.+?)(&|$)').exec(location.search)||[,null])[1]);
}
function hideURLParams() {
//Parameters to hide (ie ?playlist=value, ?video=value, etc)
var hide = ['playlist','video'];
for(var h in hide) {
if(getURLParameter(h)) {
history.replaceState(null, document.getElementsByTagName("title")[0].innerHTML, window.location.pathname);
}
}
}
window.onload = hideURLParams;
</script>
This should do the trick.
const url = 'http://aaronpenton.net/ampcreative/vip/about-vip/?playlist=f68425e&video=b8a9967'
url.replace(url.split('/')[6], '')
split, well.. splits the string into an array by the /
character.
At index 6 the array contains the ?playlist=f68425e&video=b8a9967 substring which can than be removed (i.e. replaced by the empty string) using replace.
A more general approach to removing the last part of the url might
be to use the array length instead of specifying the index:
const url = 'http://aaronpenton.net/ampcreative/vip/about-vip/?playlist=f68425e&video=b8a9967'
const urlArr = url.split('/')
url.replace(urlArr[urlArr.length - 1], '')
Update:
Another way to do this is using the URL API
const url = new URL('http://aaronpenton.net/ampcreative/vip/about-vip/?playlist=f68425e&video=b8a9967');
const result = url.origin + url.pathname
or in a function:
const removeParameter = u => {
const url = new URL(u);
return url.origin + url.pathname
}
You might have to check the specification for further details (browser support etc)
How to implement a component so that when I pass text to it.
All the hyperlinks (https://somelink.com) in the text should become tappable.
All the emails(example#example.com) in the text should open the default mail app on the device
Assuming you want a ready-to-go implementation, you could use react-string-replace following the Multiple replacements on a single string section of the docs:
const text = 'Hey #ian_sinn, check out this link https://github.com/iansinnott/ Hope to see you at #reactconf';
let replacedText;
// Match URLs
replacedText = reactStringReplace(text, /(https?:\/\/\S+)/g, (match, i) => (
<a key={match + i} href={match}>{match}</a>
));
// Match #-mentions
replacedText = reactStringReplace(replacedText, /#(\w+)/g, (match, i) => (
<a key={match + i} href={`https://twitter.com/${match}`}>#{match}</a>
));
Adjust the regexes used and components rendered to match your use case.

I want to get the title, thumnail, and video, date feilds from this response but unable to get the video because it is in div element.
You need to use DOMParser to read the HTML string into a JavaScript document. The you can use DOM methods like querySelector and getElementById on it.
Here's a function to return the video src from an HTML embed string.
const getEmbedSrc = (embed) => {
const parser = new DOMParser();
const doc = parser.parseFromString(embed, "text/html");
return doc.getElementsByTagName('iframe')[0].src;
}
const embed = "<div style='width:100%;height:0px;position:relative;padding-bottom:calc(56.25% + 335px);' class='_scorebatEmbeddedPlayerW_'><iframe src='https://www.somestream.com/embed/g/934437/?s=2' frameborder='0' width='560' height='650' allowfullscreen allow='autoplay; fullscreen' style='width:100%;height:100%;position:absolute;left:0px;top:0px;overflow:hidden;' class='_scorebatEmbeddedPlayer_'></iframe></div>";
console.log(getEmbedSrc(embed));
Alternatively, you can find a match using regex.
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>'
