Get highlighted text from div and copy into textarea javascript

Managed to get highlighted text from within a textarea and transfer it into another textarea. But when the code is edited so that it gets the highlighted text from within a div instead, it does not work...
Any ideas why this is happening? Thanks.
<div id="quote"> load transcript in here instead and grab text from here</div> // does not work
<textarea id="quote" readonly> // works
load transcript in here
</textarea>
<textarea contenteditable="false" id="output" name="selected"></textarea> // outputs highlighted text here
<script>
var quotearea = document.getElementById('quote')
var output = document.getElementById('output')
quotearea.addEventListener('mouseup', function(){
if (this.selectionStart != this.selectionEnd){ // check the user has selected some text inside field
var selectedtext = this.value.substring(this.selectionStart, this.selectionEnd)
output.innerHTML = selectedtext
}
}, false)
</script>

I answered your question in the comments and deleted it.
You're using selectionStart and selectionEnd methods that works only on input elements. For your solution used instead document.selection.createRange().text that gets the selected text in the document (inputs, divs, etc., doesn't matter).
Here's the fiddle:
Working demo

Someone in the comments answered it with a fiddle that had two textarea, but edited one to a div and it seems to work. Cheers. (Edit- turns out a div was not required, it took straight from the page, so a workaround)
<div name="" id="original">
Load transcript in here.
</div>
<textarea name="" id="copied" cols="30" rows="10"></textarea>
<script>
var text = '';
function copyText(e) {
text = (document.all) ? document.selection.createRange().text : document.getSelection();
document.getElementById('copied').value = text;
}
document.onmouseup = copyText;
if (!document.all) {
document.captureEvents(Event.MOUSEUP);
}
</script>

Replacing [b][/b] to apply BOLD text on a DIV

On my Ionic App I have a Textarea where the user can select a text and with button [BOLD]
add [b] [/b] around the selection.
How can I apply BOLD formating, replacing the [b] [/b] on the output text?
Thats my code. And here's the JsFiddle
<textarea id="TheTextInput" rows="5"></textarea>
<input type="button" id="TheButton" value="click" />
<input type="button" id="bold" value="BOLD" />
<pre id="TheOutput"></pre>
$(document).ready(function () {
$('#TheButton').click(PutTextIntoDiv);
});
function PutTextIntoDiv() {
var TheText = encodeURIComponent($('#TheTextInput').val());
$('#TheOutput').text(decodeURIComponent(TheText));
}
$( "#bold" ).click(function() {
var textArea = document.getElementById("TheTextInput");
if (typeof(textArea.selectionStart) != "undefined") {
var begin = textArea.value.substr(0, textArea.selectionStart);
var selection = textArea.value.substr(textArea.selectionStart, textArea.selectionEnd - textArea.selectionStart);
var end = textArea.value.substr(textArea.selectionEnd);
textArea.value = begin + '[b]' + selection + '[/b]' + end;
}
});
Thanks for your help!!
*Its not duplicate from Is it possible to display bold and non-bold text in a textarea?
Cause I don't want format the text inside the textarea, but the OUTPUT text.

Consider PutTextIntoDiv() replacing with:
function PutTextIntoDiv() {
$('#TheOutput').html($('#TheTextInput').val().replace(/\[b\]/g, '<b>').replace(/\[\/b\]/g, '</b>'));
}
The <pre> in your JSFiddle should render <b> fine.

You can do a RegEx replace to convert the "BBCode" tags into html tags using .replace(/\[b\](.*)\[\/b\]/g, '<b>$1</b>'). Additionally, jQuery's .text() automatically encodes HTML entities, so you will not be able to add stylized text, so you should be using .html() instead. Overall, your code should be:
function PutTextIntoDiv() {
var TheText = encodeURIComponent($('#TheTextInput').val());
$('#TheOutput').html(decodeURIComponent(TheText).replace(/\[b\](.*?)\[\/b\]/g, '<b>$1</b>'));
}
I'm not sure what the purpose of encoding and immediately decoding uri components is, but I tried to keep as much as I can untouched. Here's an updated fiddle: http://jsfiddle.net/TheQueue841/62karfm1/

div search form with formatting

I am trying to create a syntax highlighted search field, where certain items are a particular color, bold, underline, etc. when I type. As I type, I would like the word in to become bold. This works with what I currently have, but when in is typed the cursor goes to the beginning of the div, and you can't type anything after the word in either. What can I do to fix this? You can see the jsfiddle here.
The JavaScript:
$(document).on("keyup", "#q", function(){
var val = $(this).text();
val = val.replace(/\sin\s/ig, " <b>in</b> ");
$(this).html(val);
});
The HTML
<div id="q" name="q" class="form-control input-lg" contenteditable="true"></div>

With the rangy library I was able to accomplish this like this:
$(document).on("keyup", "#q", function(){
var savedSel = rangy.saveSelection();
var val = $(this).html();
val = val.replace(/\sin\s/ig, " <b>in</b> ");
$(this).html(val);
rangy.restoreSelection(savedSel);
});

converting input type text to plain text

i'm working on a small html form with 1 textbox input, after the user enters any text and he presses a button on the end of the page i want the to change to a normal plain html text(so the whole page can be copy pasted into a word file including the written down text in the textbox).
as an example:
<input type="text" id="fileserver">
<button onclick="disable_all();">click!</button>
after the button is pressed i want the textbox to be converted to plain html text with no more textbox like this:
this is an example text after pressing the button!
click!
i have been searching around and have not found a working solution yet, hope someone can help me out

$('button').click(function(){
$('body *').replaceWith(function(){
return this.value || this.innerHTML;
});
});
http://jsfiddle.net/pYw9P/

This should do it I think.
function disable_all() {
var fs = $("#fileserver"), span = $( "<span>" + fs.val() + "</span>");
span.insertAfter(fs);
fs.remove(); // or fs.hide(); in case you want it later.
}

Try:
HTML:
<input type="text" id="fileserver">
<button id="but">click!</button>
JS:
$( "#but" ).click(function() {
var text=$( "#fileserver" ).val();
$( "body" ).html(text);
});

This should be helpful to you -
There are several way to achieve your task :
Solutions 1 -
function disable_all()
{
$('#content').remove();
$('#fileserver, button').hide();
$('body').append("<div id='content'>" + $('#fileserver').val() + "</div>")
}
Working Fiddle
Solution 2 -
function disable_all()
{
$("body").html($("#fileserver").val());
}
Working Fiddle

you can do this hiding the textbox
<input type="text" id="fileserver">
<div id="result"></div>
<button id="btn" >click!</button>
and
$(document).ready(function(){
$("#result").hide();
$("#btn").click(function(){
$("#result").text($("#fileserver").val());
$("#fileserver").hide();
$("#result").show();
});
});
demo

The first "non-jQuery" answer...
your HTML:
<input type="text" id="fileserver">
<div style="display: none;" id="fileserver_text"></div>
<button id="btn">click!</button>
your Javascript:
document.getElementById('btn').onclick = disable_all;
function disable_all() {
var input = document.getElementById('fileserver');
var disp = document.getElementById('fileserver_text')
disp.innerHTML = input.value; // get the text from the input and set the div text
disp.style.display = 'block'; // show the div
input.style.display = 'none'; // hide the input
}
JSFiddle

If you are using jQUery, this will help you,
http://jsfiddle.net/DCak6/
function save(){
$('input,textarea').each(function(){
var $this = $(this);
$this.after('<span class="value">' + $this.val() + '</span>');
$this.remove();
})
}

You may be better off with taking the text from the text field, copying the value and putting it into another div
<div id="textToCopy"></div>
<input type="text" id="fileserver">
<button onclick="disable_all();">click!</button>
<script type="text/javascript">
function disable_all() {
$('#textToCopy').html($('#fileserver').val());
$('#fileserver').hide();
}
</script>

Getting text from input to replace label text in another form

reposting for simplicity. i want to have the text users enter into an input to replace the label text of another form's input. Additionally, the form is a plugin which doesn't let me attach an id to the specific label tag of the text i want to change. how can i do this, in vanilla javascript please.
the input users put text into:
<input class="charInput" id="name1" type="text" onKeyUp="change1(this)" >
the form label i want to change the text in (p.s: cant use the class(not unique to this label), cant add id):
<div id="frm_field_53_container" class="frm_form_field form-field frm_top_container">
<label class="frm_primary_label" for="field_inputactor1">
TEXT TO REPLACE
<span class="frm_required"></span>
</label></div>

Maybe it is not the best solution, but it is a solution that works in Firefox and Chrome (not tested under IE)
findLabelToChange = function() {
var div = document.getElementById("frm_field_53_container");
return div.querySelector("label");
};
customizeText = function(text) {
return text + ' <span class="frm_required"></span>';
};
change1 = function() {
var label = findLabelToChange();
var text = document.getElementById("name1").value;
label.innerHTML = customizeText(text);
};
you can see a example in this feedle
http://jsfiddle.net/HAK5X/1/

Here is a fiddle.
It is one line of code.
http://jsfiddle.net/te3jv/6/
function change1(myInput){
document.getElementById('frm_field_53_container').querySelector("label").innerHTML =myInput.value;
}
Alternatively add <span class="frm_required"></span> to the end of HTML reassignment to keep your empty (but required?) span.
