I'm running a script to sanitize pasted text in a div with contenteditable.
It's working pretty good, but in FF the line-breaks are removed if the text is copied to the same or between the divs.
Any solution for that?If I paste text from a different source the line-breaks are intact.
I'm also open to different solutions than the one below.
// Paste fix for contenteditable
$(document).on('paste', '[contenteditable]', function (e) {
e.preventDefault();
if (window.clipboardData) {
content = window.clipboardData.getData('Text');
if (window.getSelection) {
var selObj = window.getSelection();
var selRange = selObj.getRangeAt(0);
selRange.deleteContents();
selRange.insertNode(document.createTextNode(content));
}
} else if (e.originalEvent.clipboardData) {
content = (e.originalEvent || e).clipboardData.getData('text/plain');
document.execCommand('insertText', false, content);
}
});
div {
white-space: pre-wrap;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div contenteditable="true">Copy
and
paste
this
back in the same box or the one below. Where do they line-breaks go in FF?</div>

As promised, here is a working solution of such implementation discussed in question's comments.
While working with Selection and Range API (https://developer.mozilla.org/en-US/docs/Web/API/Range), i found that Range object has a toString() method and i thought to test it to see if newlines were trimmed here, before, or later.
Fortunatly, i found out that the toString() method in FF Range object doesn't trim out newlines.
According to that, here is my code and fiddle to override default copy function, overwriting (on copy event) what's inside the clipboard.
$(document).on('copy', '[contenteditable]', function (e) {
e = e.originalEvent;
var selectedText = window.getSelection();
console.log("original copied text\n--------\n", selectedText.toString());
var range = selectedText.getRangeAt(0);
var selectedTextReplacement = range.toString()
console.log("replacement in clipboard\n--------\n", selectedTextReplacement);
e.clipboardData.setData('text/plain', selectedTextReplacement);
e.preventDefault(); // default behaviour is to copy any selected text
});
// Paste fix for contenteditable
$(document).on('paste', '[contenteditable]', function (e) {
e.preventDefault();
if (window.clipboardData) {
content = window.clipboardData.getData('Text');
if (window.getSelection) {
var selObj = window.getSelection();
var selRange = selObj.getRangeAt(0);
selRange.deleteContents();
selRange.insertNode(document.createTextNode(content));
}
} else if (e.originalEvent.clipboardData) {
content = (e.originalEvent || e).clipboardData.getData('text/plain');
document.execCommand('insertText', false, content);
}
});
div {
white-space: pre-wrap;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div contenteditable="true">Copy
and
paste
this
back in the same box or the one below. Where do they line-breaks go in FF?</div>
<div contenteditable="true">Copy
and
paste
this
back in the same box or the one above. Where do they line-breaks go FF?</div>
I also made rough test with edge and chrome, and that override "doesn't mess them up", so maybe you can keep it to have control over what they are doing when something is copied.
At the end of all, i still have a question that keeps yelling in my mind and it is:
Why use contenteditable div instead of textarea if you don't want html into your frontend element?

seems easy to do it for chrome but that option doesn't work in other browsers
I have a few requirements
I would like to copy text to clipboard
to be able to copy a section of html with multiple elements
To work in safari and chrome at least
Vanilla Javascript
I have found this solution and it works except that it copies the html tags as well?
i tried changing the .innerHTML to .value on the button, but that comes back undefined

sends html code inside #something to copyToClipboard and this behavior you mentiond is expected . what do you want to be copied to clipboard if not html ?

I'm building a chrome extension where selected text can have different highlighting styles applied to it. I used ranges to get this all to work, and I clone the range, put a span around it, and then delete the range and replace it with the cloned one. Everything seems fine except I've somehow managed to disable right clicking by triggering this behavior through the extension. I've narrowed it down the single line of range.surroundContents(span), but here's the full code section:
// Determines the selected text
document.onmouseup = function() {
var selection = document.getSelection();
selection = getSelectedText(color);
};
// Finds the text selected in the page, spans it, and gives it a class
function getSelectedText(inputColor) {
var span = document.createElement('span');
span.setAttribute('class', inputColor);
if(document.getSelection) {
var selection = document.getSelection();
if(selection.rangeCount == true) {
var range = selection.getRangeAt(0).cloneRange();
range.surroundContents(span);
selection.removeAllRanges();
selection.addRange(range);
}
}
}
Is there a way I can counter this? I've already tried using document.oncontextmenu = false directly following the problem line, but that's not bringing back right click. I also tried replacing it with newNode.appendChild(range.extractContents()); range.insertNode(newNode) as recommended by https://developer.mozilla.org/en-US/docs/Web/API/Range/surroundContents but then instead of highlighting text, it seems to just be removing it from the page.
#wOxxOm answered my question in a comment, but a setTimeout() is what worked. So for anyone else who might have a similar issue in the future:
// Finds the text selected in the page, spans it, and gives it a class
function getSelectedText(inputColor) {
var span = document.createElement('span');
span.setAttribute('class', inputColor);
if(document.getSelection) {
var selection = document.getSelection();
if(selection.rangeCount == true) {
var range = selection.getRangeAt(0).cloneRange();
setTimeout(function(){
range.surroundContents(span);
selection.removeAllRanges();
selection.addRange(range);
}, 100)
}
}
}
suppose to be we have a paragraph with this content " Hi , It's a new question in stackoverflow!"
and when we are selecting something in this paragraph , it's turn to be Red .for example we selected stackoverflow & then it turn to <span class="red">stackoverflow</span>.how can we do this with Javascript?
here is my codes :
var x = {};
x.getSelected = function() {
var t = '';
if (window.getSelection) {
t = window.getSelection();
} else if (document.getSelection) {
t = document.getSelection();
} else if (document.selection) {
t = document.selection.createRange().text;
}
return t;
}
$(document).ready(function() {
var selectedText;
$(document).bind("mouseup", function() {
selectedText = x.getSelected()
if (selectedText !=''){
alert(selectedText);
//Now I wanna set new content for selected item but not working
a=selectedText;
selectedText.html("<span class='red'>"+a+"</span>");
}
});
});
.red {
color : red;
}

You could have a stab at the styleWithCSS command of the editing API, execCommand that is.
However, before proceeding please note that:
This spec is incomplete and it is not expected that it will advance
beyond draft status. Authors should not use most of these features
directly, but instead use JavaScript editing libraries. The features
described in this document are not implemented consistently or fully
by user agents, and it is not expected that this will change in the
foreseeable future.... This spec is to meant to help implementations
in standardizing these existing features. It is predicted that in the
future both specs will be replaced by Content Editable Events and
Input Events....
Having clarified that, the following will work in most modern browsers viz. Edge, FireFox and Chrome that I could test in.
By default the foreColor command of execCommand wraps the selected text with a font tag, which is deprecated. So, you need to use the styleWithCSS command. Now this works with the editing API, which means that the element you are trying to work with, should have its contentEditable attribute set.
To work around this, you can temporarily set this attribute just before changing the color in the selected text fragment and then resetting the attribute once done.
Given your paragraph like this:
<p id="p">
Hi , It's a new question in StackOverflow!
</p>
When you select the word StackOverflow, the following code will result in this...
<p id="p">
Hi , It's a new question in <span style="color: rgb(255, 0, 0);">StackOverflow</span>!
</p>
... wrapping your selected text in a span with the style applied.
Fiddle: http://jsfiddle.net/abhitalks/j9w6dj7m/
Snippet:
p = document.getElementById('p');
p.addEventListener('mouseup', setColor);
function setColor() {
p.setAttribute('contentEditable', true);
document.execCommand('styleWithCSS', false, true);
document.execCommand('foreColor', false, "#f00");
p.setAttribute('contentEditable', false);
}
<p id="p" contentEditable="false">
Hi , It's a new question in stackoverflow!
</p>
Edit:
Now that you have added code (and what you have already tried) in your question, you could use the range selection to do what you are after.
Specifically, you will need to learn:
selection: https://developer.mozilla.org/en-US/docs/Web/API/Selection, this you have already done. Cheers!
range: https://developer.mozilla.org/en-US/docs/Web/API/Range/Range, because you will be dealing with ranges here
selection.getRangeAt(): https://developer.mozilla.org/en-US/docs/Web/API/Selection/getRangeAt, because you will need to extract the selected text as a range object
range.surroundContents(): https://developer.mozilla.org/en-US/docs/Web/API/range/surroundContents, because you will need to surround the selected text range with a span.
Putting it all together all you have to do is (explanation in code comments):
function setClass() {
var selection = x.getSelected(), range, // you have already done this
span = document.createElement("span"); // create a span element
span.classList.add('red'); // add the class to the span
if (selection != '') {
range = selection.getRangeAt(0); // get the range from selected text
range.surroundContents(span); // surround the range with span
}
}
Fiddle 2: http://jsfiddle.net/abhitalks/kn0u5frj/
Snippet 2:
var x = {},
p = document.getElementById('p');
p.addEventListener('mouseup', setClass);
function setClass() {
var selection = x.getSelected(), range,
span = document.createElement("span");
span.classList.add('red');
if (selection != '') {
range = selection.getRangeAt(0);
range.surroundContents(span);
}
}
x.getSelected = function() {
var t = '';
if (window.getSelection) {
t = window.getSelection();
} else if (document.getSelection) {
t = document.getSelection();
} else if (document.selection) {
t = document.selection.createRange().text;
}
return t;
}
.red { color: #f00; }
<p id="p">
Hi , It's a new question in stackoverflow!

You can use the getSelection() method
Below is the example:
Repeated Question:
How to get selected text in textarea?
You can use CSS with :: selection http://caniuse.com/#search=%3A%3Aselection
::selection {
background: #ffb7b7; /* WebKit/Blink Browsers */
}
::-moz-selection {
background: #ffb7b7; /* Gecko Browsers */

I'm working on a specialized Text/HTML Editor with Javascript and JQuery in a contenteditable div. I implemented the different text styles (bold, italic,...) with execcommand. This seems to work only if the selected text is not empty. What is the best way to solve this problem?
Here an example of what I want to do with Text being the text in the editor, HTML being the corresponding html code and | being the cursor Position:
Text: Hello| World
HTML: <b>Hello| World</b>
By pressing a "bold" button, the execcommand('bold')-command should be executed on the selected position and the caret should be placed inside the modified position.
Text: Hello| World
HTML: <b>Hello</b>|</b> World</b>
This does not work. I found a Workaround by adding an text node containing a blank. This seems to work in Internet Explorer, but not in Firefox. Here a simple example:
HTML:
<div id="textcontent" contenteditable="true" overflow:auto;"><p>Enter text</p></div>
<button type="button" id="setBold">Bold</button>
Javascript:
$('#setBold').click(function () {
if (document.getSelection() != "") {
document.execCommand('bold');
}
else {
var selObj = document.getSelection();
var selRange = selObj.getRangeAt(0);
var newNode = document.createTextNode(' ');
selRange.deleteContents();
selRange.insertNode(newNode);
selObj.removeAllRanges();
selObj.addRange(selRange);
document.execCommand('bold');
selRange.deleteContents();
selObj.removeAllRanges();
selObj.addRange(selRange);
}
});
And the corresponding jsfiddle here: http://jsfiddle.net/andibioticum/3V7pK/
I modified my workaround-solution by inserting a text node containing a letter, calling the execcommand on that node, deleting it afterwards and setting the caret with focus().
$('#setBold').click(function () {
if (document.getSelection() != "") {
document.execCommand('bold');
}
else {
//get selected position
var selObj = document.getSelection();
//get range of selected position
var selRange = selObj.getRangeAt(0);
//Insert node with dummy text 'd'
var newNode = document.createTextNode('d');
selRange.insertNode(newNode);
selObj.removeAllRanges();
selObj.addRange(selRange);
//Execute command on dummy
document.execCommand('bold');
//Delete dummy from range
selRange.setStart(newNode, 0);
selRange.setEnd(newNode, 1);
selRange.deleteContents();
selObj.removeAllRanges();
selObj.addRange(selRange);
//Focus on empty element
$('#textcontent').focus();
}
});
See the fiddle here: http://jsfiddle.net/andibioticum/XJuRf/
My JS code:
function getSelectedText(){
if(window.getSelection){
select = window.getSelection().getRangeAt(0);
var st_span = select.startContainer.parentNode.getAttribute("id").split("_")[1];
var end_span = select.endContainer.parentNode.getAttribute("id").split("_")[1];
console.log(select.endContainer);
var ret_urn=[st_span,end_span];
return ret_urn
}
else if(document.getSelection){
return document.getSelection();
}
}
$(document).ready(function() {
$("div#check_button button").click(function () {
var loc = getSelectedText();
console.log(loc);
});
});

It is hard to explain it, so I prepared short movie: http://www.youtube.com/watch?v=tVk4K70JO80
In a few words: when I press left mouse button and hold it to select text/numbers and start selection from the half of letter/number, although this letter/number is not highlighted, it is added to selection. I have to start selection precisely. It is ok with wide letters, but hard with letters like i,j or l.
This is second example of my movie. I pressed left button on 3/4 of length of number 5, although 5 is not highlighted, it is selected.
Tested on FF and Opera.
Ok just tried this demo. and it works flawlessly. it even works on firefox. Just tested opera and safari and it works on both of them as well. Even if i select half a letter or number, it just returns the highlighted text which is what is expected when you make a selection.
try it out on a fresh webpage though just for testing purposes. then when it works and you are satisfied with the results then start making changes to your existing page.
Its a lot more simpler than your code. This is a cross-browser script to get text selected by the user
<script language=javascript>
function getSelText()
{
var txt = '';
if (window.getSelection)
{
txt = window.getSelection();
}
else if (document.getSelection)
{
txt = document.getSelection();
}
else if (document.selection)
{
txt = document.selection.createRange().text;
}
else return;
document.aform.selectedtext.value = txt;
}
</script>
<input type="button" value="Get selection" onmousedown="getSelText()">
<form name=aform >
<textarea name="selectedtext" rows="5" cols="20"></textarea>
</form>
http://www.codetoad.com/javascript_get_selected_text.asp
Hope this helps.

There are multiple different boundary points for a selection that will look the same to the user. What you're seeing is probably the difference between the following, where | is a selection boundary:
<span>5</span><span>|6</span><span>7|</span><span>8</span>
and
<span>5|</span><span>6</span><span>7</span><span>|8</span>
In both cases, calling toString() on the selection will give you the same result ("67").
