Changelog verpflichtend machen mittels Tag

Um den Changelog zu einem Pflichtfeld zu machen muss folgender Code in die Personalisierung von Bookstack eingebaut werden: 

 <script type="module">

 const requiredMessage = 'Bitte geben Sie einen Changelog ein.';

 const form = document.querySelector('#main-content > form');

 const changelogInput = document.getElementById("summary-input");

 let changelogRequired = false;

 function isChangelogEmpty() {

 return changelogInput.value.trim() === "";

 }

 function checkChangelogOnSubmit(event) {

 if (!isChangelogEmpty() || !changelogRequired) {

 return;

 }

 event.preventDefault();

 window.$events.error(requiredMessage);

 }

 async function isChangelogRequired() {

 const bookSlugRegex = /\/books\/(.*?)\/(page|draft)\//;

 const slugMatchResults = bookSlugRegex.exec(window.location.href);

 if (slugMatchResults === null) {

 return false;

 }

 const bookSlug = slugMatchResults[1];

 const bookResp = await window.$http.get(`/books/${bookSlug}`);

 const parser = new DOMParser();

 const pageDom = parser.parseFromString(bookResp.data, 'text/html');

 return pageDom.querySelector('body.tag-pair-changelog-required') !== null;

 }

 if (form && changelogInput) {

 form.addEventListener("submit", checkChangelogOnSubmit);

 window.addEventListener('DOMContentLoaded', () => {

 isChangelogRequired().then(required => {

 changelogRequired = required;

 });

 });

 }

 window.addEventListener('editor-tinymce::setup', event => {

 const editor = event.detail.editor;

 editor.on('init', () => {

 editor.shortcuts.remove('meta+13');

 editor.shortcuts.add('meta+13', '', () => {

 if (!isChangelogEmpty() || !changelogRequired) {

 window.$events.emit('editor-save-page', {});

 } else {

 window.$events.error(requiredMessage);

 }

 });

 });

 });

</script> 

 Dieses Script nur dann aktiv, wenn ein Buch den Tag Changelog mit dem  Tagvalue required besitzt.
