How can I add a new format (<hr> tag) to Quill.js?
I have still no idea why the question has downvotes, but however here is the solution:
Import the embed blot - important: not "block", not "embed", "block/embed"!
var Embed = Quill.import('blots/block/embed');
Define a new class that extends that Embed
class Hr extends Embed { static create(value) { let node = super.create(value); // give it some margin node.setAttribute('style', "height:0px; margin-top:10px; margin-bottom:10px;"); return node; }}
Define your tag
Hr.blotName = 'hr'; //now you can use .ql-hr classname in your toolbarHr.className = 'my-hr';Hr.tagName = 'hr';
Write a custom handler for the <hr> button
var customHrHandler = function(){ // get the position of the cursor var range = quill.getSelection(); if (range) { // insert the <hr> where the cursor is quill.insertEmbed(range.index,"hr","null") }}
Register your new format
Quill.register({ 'formats/hr': Hr});
Instantiate your Editor with the right selectors in your HTML
var quill = new Quill('#editor', { modules: { toolbar: { container: '#toolbar-container', handlers: { 'hr': customHrHandler } } }, theme: 'snow'});
The HTML part remains the same. The whole <hr> functionality can be done similar to the <img> format.
Thank you, you helpful community.
Not enough rep to comment, so posting as an answer, to address a minor issue.
The default prompt box caused by the embed shown in @Suisse's great answer has to be seemingly handled in a toolbar handler (with a second parameter), like so:
var toolbarOptions = { handlers: { // ... 'hr': function(value) { this.quill.format('hr', true); } }}
