VistasGet div's value to insert to textarea js
I have a div behaving as a textarea where I can insert text. I want to mirror value as user typing in this div, to a second textarea in order to be formatted and to send to DB consequently. However, I seem to be having trouble taking div's value. It worked smoothly as I had a regular textarea. Here I used .text() instead of .val() but it doesn't add br. It is supposed to add br as user start a new line.

$('#fake_textarea').keyup(function(){
var val = $('#fake_textarea').text();
val = val.replace(/\n/g, '<br />\n')
$('#second').val(val);
});
.textbox {
-moz-appearance: textfield-multiline;
-webkit-appearance: textarea;
border: 1px solid gray;
font: medium -moz-fixed;
font: -webkit-small-control;
height: 28px;
overflow: auto;
padding: 2px;
resize: both;
width: 200px;
min-height: 50px;
}
textarea {
width: 200px;
height: 50px;
}<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="textbox" id="fake_textarea" contenteditable></div>
<textarea type="text" id="second"></textarea>2 Respuestas

When using contenteditable, the child element is created in html element, so you have to parse it and change it to text. The appropriate property at this time is textContent.
$('#fake_textarea').on('input', function(){
var val = $('#fake_textarea')
.contents()
.map((_,el)=> el.textContent + '<br/>\n')
.toArray()
.join('');
$('#second').val(val);
});

Easy using vanilla JS.
The text you enter in your divis internally wrapped into sub-div elements. Just connect those subdivs' textContentwith a newline character, and assign it to the textarea's textContent.
fake_textarea.addEventListener('input', (e) => {
second.textContent = [...fake_textarea.querySelectorAll('div:not(.textbox)')].map(e => e.textContent).join('\n')
}).textbox {
-moz-appearance: textfield-multiline;
-webkit-appearance: textarea;
border: 1px solid gray;
font: medium -moz-fixed;
font: -webkit-small-control;
height: 28px;
overflow: auto;
padding: 2px;
resize: both;
width: 200px;
min-height: 50px;
}
textarea {
width: 200px;
height: 50px;
}<div class="textbox" id="fake_textarea" contenteditable></div>
<textarea type="text" id="second"></textarea>
