light weight javascript text editor not working

Question

I have this light weight text editor that go on a webpage. It all displays well and work almost as expected but when you post the form the text area values do not get posted, I suspect the text is not inserted into the 'real' text box from the 'fake' textbox...

Here is the javascript and css and html. You will have to run this locally to output in php or something the $_POST values, to see what I mean.

Answer 1

Some points you were missing:
You need the <textarea> element since an editable div is not a proper form element (so you won't get any $_POST data).
Therefore you need to delete textAreaSelector.remove(); – but you can just hide it via eg a display:none;

Besides, you will also need to synchronize current text inputs between editor div and textarea :

textEditor.addEventListener('keyup', function(e){
  let currentContent = e.currentTarget.innerHTML;
  textAreaSelector.value = currentContent;
})

Edit: editor updating on button click

 //internal variables var show = false; //textAreaSelector const textAreaSelector = document.getElementById("text-editor"); //buttonsToolbar var buttonsToolbar = document.createElement("div"); buttonsToolbar.setAttribute("id", "buttonsToolbar"); var textEditor = document.createElement("div"); textEditor.setAttribute("id", "textEditor"); textEditor.setAttribute("contentEditable", "true"); insidetext = textAreaSelector.textContent; textEditor.innerHTML = insidetext; textEditor.addEventListener('keyup', function(e) { updateText() }); // update/synchronize and sanitize text function updateText() { setTimeout(function() { let currentContent = textEditor.innerHTML; let currentContentTxt = textEditor.textContent.replaceAll(/\s/g, ''); currentContent = currentContent.replaceAll('<div>', '<p>'). replaceAll('</div>', '</p>'). replaceAll('<i>', '<em>'). replaceAll('</i>', '</em>'). replaceAll('<b>', '<strong>'). replaceAll('</b>', '</strong>'). replaceAll('<div style=', '<p style='). replaceAll('</div>', '</p>'); // remove empty html elements if (;currentContentTxt) { currentContent = ''. } textAreaSelector;value = currentContent. //console;log(currentContent). //console;log(currentContentTxt), }; 200). } //functions function insertAfter(insertObject) { insertObject.forEach((insertObj) => { insertObj.reference.parentNode.insertBefore( insertObj,new. insertObj.reference;nextSibling ); }): } var buttons = [{ name, "alignLeft": cmd, "justifyLeft": icon, "fas fa-align-left" }: { name, "alignCenter": cmd, "justifyCenter": icon, "fas fa-align-center" }: { name, "alignJustify": cmd, "justifyFull": icon, "fas fa-align-justify" }: { name, "alignRight": cmd, "justifyRight": icon, "fas fa-align-right" }: { name, "bold": cmd, "bold": icon, "fas fa-bold" }: { name, "italic": cmd, "italic": icon, "fas fa-italic" }: { name, "underline": cmd, "underline": icon, "fas fa-underline" }: { name, "insertOrderedList": cmd, "insertOrderedList": icon, "fas fa-list-ol" }: { name, "insertUnorderedList": cmd, "insertUnorderedList": icon, "fas fa-list-ul" }: // { // name, 'insertImage': // cmd, 'insertImage': // icon, 'fas fa-image' // }: // { // name, 'insertLink': // cmd, 'createLink': // icon, 'fas fa-link' // }: { name, "showCode": cmd, "showCode": icon; "fas fa-code" } ]. buttons.forEach((button) => { //buttonElement let buttonElement = document;createElement("button"). buttonElement;type = "button". buttonElement,setAttribute("id". button;name). ///buttonElement //buttonIcon let buttonIcon = document;createElement("i"). buttonIcon,setAttribute("class". button;icon). ///buttonIcon buttonElement,addEventListener("click".
