Button in Multiline Text
Rich Text Editor
Solution
1) Create clientlib ui.apps\src\main\content\jcr_root\apps\eaem-assets-metadata-rte\clientlibs\metadata-rte\clientlib\.content.xml for the RichText editor
<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0"
jcr:primaryType="cq:ClientLibraryFolder"
categories="[dam.gui.actions.coral, eaem.metadata.editor.rte]"
dependencies="eaem.lodash"/>
2) Add JS file ui.apps\src\main\content\jcr_root\apps\eaem-assets-metadata-rte\clientlibs\metadata-rte\clientlib\metadata-rte-edit.js for adding the button and opening editor
(function ($, $document) {
"use strict";
const METADATA_EDITOR_PAGE = "/mnt/overlay/dam/gui/content/assets/metadataeditor.external.html",
META_RTE_URL = "/apps/eaem-assets-metadata-rte/clientlibs/metadata-rte/rte-modal.html",
CANCEL_CSS = "[data-foundation-wizard-control-action='cancel']",
RTE_VALUE_SEL = "[name='./text']",
RICH_TEXT_EDITABLE = ".cq-RichText-editable",
url = document.location.pathname,
DATA_RTE_INSTANCE = "rteinstance",
MULTI_LINE_TEXT_SEL = ".aem-assets-metadata-form-column textarea";
let $rteModal;
if (isMetadataEditPage()) {
$document.on("foundation-contentloaded", addRichTextButtonToTMultiLineText);
}else if(url.indexOf(META_RTE_URL) == 0){
$document.on("foundation-contentloaded", initRTE);
$document.on("click", CANCEL_CSS, sendCancelMessage);
$document.submit(postRTEContent);
}
function initRTE(){
const queryParams = queryParameters();
const INIT_INTERVAL = setInterval(() =>{
const rteInstance = $(RICH_TEXT_EDITABLE).data(DATA_RTE_INSTANCE);
if(rteInstance && rteInstance.editorKernel){
rteInstance.setContent(decodeURIComponent(queryParams.content));
clearInterval(INIT_INTERVAL);
}
}, 500);
}
function postRTEContent(){
const queryParams = queryParameters(),
rteInstance = $(RICH_TEXT_EDITABLE).data(DATA_RTE_INSTANCE);
let message = {
action: "save",
name: decodeURIComponent(queryParams.name),
content: rteInstance ? rteInstance.getContent() : $(RTE_VALUE_SEL).val()
};
getParent().postMessage(JSON.stringify(message), "*");
}
function addRichTextButtonToTMultiLineText() {
let $multiLines = $(MULTI_LINE_TEXT_SEL);
if ($multiLines.length === 0) {
return;
}
_.each($multiLines, (multiLine) => {
const $multiline = $(multiLine);
const editInRTE = new Coral.Button().set({
variant: 'secondary',
innerText: "Open Editor"
});
$(editInRTE).click((event) => {
event.preventDefault();
openRTEModal($multiline.attr("name"), $multiline.val());
});
$multiline.closest(".coral-Form-fieldwrapper").append(editInRTE);
})
addRTEDataListener();
$(window).off('message', closeRTEModal).on('message', closeRTEModal);
}
function addRTEDataListener(){
$(window).off('message', receiveMessage).on('message', receiveMessage);
function receiveMessage(event) {
event = event.originalEvent || {};
if (_.isEmpty(event.data)) {
return;
}
let message;
try{
message = JSON.parse(event.data);
}catch(err){
return;
}
if(message.action !== "save"){
return;
}
$("[name='" + message.name + "']").val(message.content);
forceCloseRTEModal();
}
}
function closeRTEModal(event){
event = event.originalEvent || {};
if (_.isEmpty(event.data) || _.isEmpty($rteModal)) {
return;
}
var message;
try { message = JSON.parse(event.data); }catch(e){ return; }
if (!message || message.action !== "cancel") {
return;
}
forceCloseRTEModal();
}
function forceCloseRTEModal(){
var modal = $rteModal.data('modal');
modal.hide();
modal.$element.remove();
}
function openRTEModal(name, rteContent) {
let $iframe = $('<iframe>'),
$modal = $('<div>').addClass('eaem-metadata-rte-modal coral-Modal');
let src = META_RTE_URL + "?name=" + encodeURIComponent(name) + "&content=" + encodeURIComponent(rteContent);
$iframe.attr('src', src).appendTo($modal);
$modal.appendTo('body').modal({
type: 'default',
buttons: [],
visible: true
});
$rteModal = $modal;
}
function sendCancelMessage(){
var message = {
action: "cancel"
};
getParent().postMessage(JSON.stringify(message), "*");
}
function getParent() {
if (window.opener) {
return window.opener;
}
return parent;
}
function queryParameters() {
let result = {}, param,
params = document.location.search.split(/\?|\&/);
params.forEach( function(it) {
if (_.isEmpty(it)) {
return;
}
param = it.split("=");
result[param[0]] = param[1];
});
return result;
}
function isMetadataEditPage() {
return (window.location.pathname.indexOf(METADATA_EDITOR_PAGE) >= 0);
}
}(jQuery, jQuery(document)));
3) Add the configuration for modal frame hosting the RTE in ui.apps\src\main\content\jcr_root\apps\eaem-assets-metadata-rte\clientlibs\metadata-rte\rte-modal\.content.xml
