Always vertically center content of a textarea input - javascript

i'm working on a small project where textarea are used.
And the problem with textarea is that the text always start at the top left corner...
And what i want is to have the content inside of that textarea always centered. And then if I add a line it'll expend from the middle, something like this :
I looked for thing like vertical align and thing like that, but i also saw things about inserting a div... But i was wondering if there was a solution with textarea
Thanks !

I don't think you can align the text in textarea vertically, but you can fake it!
HTML and CSS:
Create a resizable div
Nest a contenteditable p in that div
Add a placeholder for the p when it's empty
Use flexbox to set the p in the middle: align-items: center;
Add p {white-space: pre-line;} to prevent the overflow when typing
Add p {outline: 0px solid transparent;} to remove the border on focus
JavaScript:
Get the target (p)
Add an event on keypress
Check for pressing Enter
Prevent the default event and insert a line break (new line) instead
Add an event on click to the div to focus the p (textarea behavior)
// Get the target
let p = document.querySelector('p');
let div = document.querySelector('div');
// Add event onkeypress
p.addEventListener('keypress', (e) => {
let keyCode = e.code || e.key;
// Check for pressing 'Enter'
if(keyCode === 'Enter') {
// Prevent the default event and insert line break (new line) instead
document.execCommand('insertLineBreak');
e.preventDefault();
}
});
// Add event onclick
div.addEventListener('click', () => {
// Focus on p to get the textarea behavior
p.focus();
});
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
div {
resize: both;
width: 200px;
height: 150px;
border: 1px solid;
overflow: auto;
margin: 30px auto;
display: flex;
align-items: center;

}

}
<div>
<p contenteditable="true" placeholder="Type here..."></p>

After adding span tag in contenteditable cursor move to end in IOS safari

I have a feature where users can click on the tag and the same has been added to contenteditable div. this works fine but when I do it back and forth the cursor moves the end of the div.
This is when user adds variable first time and cursor seems fine.
This is when user remove and add tag again
The tag has been added by the following code and this issue is happing in ios safari only.
insertTextAtCursor = (text, paste = false) => {
const sel = window.getSelection();
// Make sure we're focused on the compose element
this.compose.focus(); // contenteditable div ref
if (sel.getRangeAt && sel.rangeCount) {
const range = sel.getRangeAt(0);
range.deleteContents();
if (paste) {
range.insertNode(document.createTextNode(text));
range.selectNode(document.createTextNode(text));
} else {
range.insertNode(text);
range.selectNode(text);
}
// calling deleteContents and replacing with HTML leaves behind an empty node, so here we clean discard it.
const newRange = range.cloneRange();
range.setEndBefore(text);
newRange.setStartAfter(text);
newRange.setEndAfter(text);
sel.removeAllRanges();
sel.addRange(newRange);
}
}
Edit
The cursor becomes too big after adding display: inline-block property.
HTML
<div id="variable-message-input-message-fb39fc57-7909-47e2-9de8-042e70eee3ad" class="variable-message__compose" contenteditable="true" name="message" placeholder="" style="
/* display: inline-block; */"><span spellcheck="false" contenteditable="false" id="span-First Name" class="variable-message__variable"><i>{</i><div>First</div><b>_</b><div>Name</div><i>}</i><span class="variable-message__close"></span></span></div>
CSS
background-color: #fcfcfc;
border: 1px solid #e3e3e3;
border-top-left-radius: .2rem;
border-top-right-radius: .2rem;
color: #404040;
min-height: 4rem;
padding: 1rem 1.2rem;
Try add this below css
[contenteditable] {
display: inline-block;
}

How can I "word wrap" a div within a container div?

I am making a comma separated "tag" type system, and I want the tags to scroll left to right, then go to the next line if the next tag would cause that line to be wider than the max width of the container.
I get different results if I use <span> or <div>
<span class="tag"><span class="tagspan" ></span></span>
<div class="tag"><span class="tagspan" ></span></div>
but neither one correctly wraps to the next line. ( If I use span it WILL wrap to next line, but it will break the tag in half and place the rest of it on the next line ).
Surely there must be an easy fix for this. I am trying to avoid having to calculate the width of each line and compare its current width to the width it would be if the next tag were added, then deciding if there needs to be a line break or not.
Any suggestions would be greatly appreciated.
JS Bin Here
jQuery:
$('document').ready( function() {
var value;
var tag;
var cloned;
$('#tag').on( 'change keyup', function(){
value = $('#tag').val();
tag = value.split(',');
if (tag[1] != null && tag[0] !== ''){
cloned = $('.tag').first().clone().appendTo('#container');
$(cloned).find('span').html(tag[0]);
$(cloned).css({'opacity' : '1', 'width' : $(cloned).find('span').width() + 'px'});
$('#tag').val('');
}
if (tag[1] != null && tag[0] === ''){
$('#tag').val('');
}
console.log($('.tagspan').width() + 'px');
});
});
You can use float:left to your tag elements instead of the container and drop the display:inline-flex attribute which results in a line break if your tags reach the end of the line. Edit: change the outer span elements to divs for that effect.
// thanks Gary ;)
This is more related to CSS styling than JavaScript code, I think I got it working just tweaking two classes in your CSS code:
span {
vertical-align:middle;
display: inline-flex;
word-break: keep-all;
}
#container {
text-align: left;
display: block;
min-width:400px;
max-width:400px;
height:100px;
border:1px solid;
}
This is how it looks like:
The thing is, span elements must fit into its parent element, that's why you should make children display inline and not its parent.
Working example: Wrap span tags into DIV
Given that you were working with flexbox, you might want to try add to your .container class flex-wrap:wrap; This acheives a similar effect.
There are a few styles that are causing problems for you (referencing the JSBin you posted). The following should fix your problems:
.tag {
border: 3px ridge #336699;
height: 20px;
background: rgba(0, 0, 170, .25);
border-radius: 20px;
text-align: center;
font-family: arial;
font-size: 15px;
color: #336699;
font-weight: bold;
padding: 2px 8px;
margin: 2px;
opacity: 0.0001;
float: left;
display: none;
}
#container {
width: 400px;
height: 100px;
border: 1px solid;
}
then adjust your JavaScript to the following:
$(function() {
var value,
tag,
cloned;
$('#tag').on('change keyup', function(e) {
value = $('#tag').val();
tag = value.split(',');
if (tag[1] != null && tag[0] !== '') {
cloned = $('.tag').first().clone().appendTo('#container');
$(cloned).find('span').html(tag[0]);
$(cloned).css({'opacity' : '1', 'min-width' : $(cloned).find('span').width() + 'px', 'display': 'inline-block'});
$('#tag').val('');
}
if (tag[1] != null && tag[0] === '') {
$('#tag').val('');
}
});
});

Edit cursor not displayed on Chrome in contenteditable

When you open this page (see Live demo) with Chrome :
<span id="myspan" contenteditable=true></span>
CSS :
#myspan { border: 0; outline: 0;}
JS :
$(myspan).focus();
the contenteditable span has focus (you can start to write things and you will see that it already had focus), but we don't see the "I" edit cursor.
How to make that this cursor is displayed ? (Remark : outline:0 is needed, as well as the fact that the span is empty even with no white space).
Note : With Firefox, the cursor is displayed.
The problem is that spans are inline elements. Just add display:block; to your CSS and it will fix the problem.
$(myspan).focus();
#myspan {
border: 0;
outline: 0;
display: block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<span id="myspan" contenteditable=true></span>
I added padding to the left and the cursor appears.
#myspan
{
border: 0;
outline: 0;
min-width: 100px;
height: 30px;
padding-left: 1px;
}
Demo in jsFiddle
.cont_edit {
outline: 1px solid transparent;
}
This just has to do with the way an empty ContentEditable area is rendered. To prove it's not about the focus, add some text to your editable div, and then delete it. When the last character is gone, the cursor will disappear
From the question Setting the caret position to an empty node inside a contentEditable element
The selection/range model is based around indexes into text content, disregarding element boundaries. I believe it may be impossible to set the input focus inside an inline element with no text in it. Certainly with your example I cannot set focus inside the last element by clicking or arrow keys.
It almost works if you set each span to display: block, though there's still some highly strange behaviour, dependent on the existence of whitespace in the parent. Hacking the display to look inline with tricks like float, inline-block and absolute position make IE treat each element as a separate editing box. Relative-positioned block elements next to each other work, but that's probably impractical.
You could also try adding a zero-width character like ​
document.getElementById('myspan').focus();
#myspan {
border: 0;
outline: 0;
}
<span id="myspan" contenteditable="true">​</span>
The solution was to change <span> to <div> (I've seen that this solves many contenteditable problems in other questions here and there) + to add a min-width.
Indeed, with the following code, the size of the <div> would be 0px x 18px ! That explains why the caret (edit cursor) would be hidden !
HTML
<div id="blah" contenteditable=true></div>
CSS
#blah {
outline: 0;
position: absolute;
top:10px;
left:10px;
}
JS
$("#blah").focus();
Then, adding
min-width: 2px;
in the CSS will allow the caret to be displayed, even with Chrome : http://jsfiddle.net/38e9mkf4/2/
The issue I faced on Chrome v89.0.4389.90 was that contenteditable fields would sometimes show the blinking caret on focusin and sometimes not. I noticed it always blinks when there's already content in the field before focusing. It's when there's no content that the sometimes will/won't behavior occurs.
At first, I thought there must be some conflicting event handler that's erratically taking focus away. I disabled all my event binds and timers. Still the same erratic behavior. Then I thought it might be some conflicting CSS, so I disabled all stylesheets. At least now the behavior was consistent: the caret blinks 100% of the time when the field has content; the caret does not blink 100% of the time when the field has no content.
I enabled binds and stylesheets again. My div was already set to display: block; with min-width, min-height, and padding set in the final computed style set. None of the other answers here worked. I do have a placeholder on :empty:before that was a possible culprit. I commented that out. Now the behavior was consistent again, same as if the stylesheet was off. Oddly enough, the runnable snippet on SO works with the same computed CSS stack. I want to keep the placeholder, so it requires further research with my actual codebase...
The only solution I could get to work 100% of the time with my current issue involved forcibly placing the caret inside empty fields by creating a blank space and removing it immediately afterwards. Best I can do for a workaround until debugging the root cause.
//force caret to blink inside masks
let force_caret = function() {
if (!this.textContent) {
this.textContent = ' ';
let r = document.createRange(),
s = window.getSelection();
r.setStart(this.childNodes[0], 0);
r.collapse(true);
s.removeAllRanges();
s.addRange(r);
this.textContent = '';
}
}
//binds
let els = document.querySelectorAll("[contenteditable]");
for (let i = 0; i < els.length; i++) {
els[i].addEventListener('focusin', force_caret, false);
}

<span>x</span>
<div maxlength="5" contenteditable="true" class="mask"></div>
</div>
Add a CSS style of
min-height: 15px;
you may also need
display: block;
to your contenteditable="true" tag
For me setting it content of contenteditable div to <br> works. I tried setting it to nbsp; but that creates extra character space in the div before i start editing. So, i choose this:
<div id="blah" contenteditable=true><br></div>
over:
<div id="blah" contenteditable=true>nbsp;</div>
Hope this helps.
I use Chrome and your Code works fine.
Try to use cursor: text; in your CSS. See here

How to prevent textarea from scrolling to the top when its value changed?

Consider the following example: (Live demo here)
HTML:
<textarea></textarea>
<div id="button">Click Here</div>
CSS:
textarea {
height: 80px;
width: 150px;
background-color: #bbb;
resize: none;
border: none;
}
#button {
width: 150px;
background-color: #333;
color: #eee;
text-align: center;
}
JS:
$(function() {
var textarea = $("textarea");
textarea.val("Hello\nStack\nOverflow!\nThere\nAre\nLots\nOf\nGreat\nPeople\nHere");
$("#button").click(function() {
textarea.val(textarea.val() + "!");
});
textarea.scrollTop(9999).focus(); // Arbitrary big enough number to scroll to the bottom
});
When the #button is clicked, textarea value changes, and for some reason the scroll bar goes to the top (I checked this in Firefox, not sure about other browsers).
Why this is happening ?
How could I fix that ?
I found here one possible solution, but I wonder if there are other solutions.
You can save the scrollTop offset, set the value, and reset the scrollTop to the old offset:
var $textarea = ...;
var top = $textarea.scrollTop();
$textarea.val('foo');
$textarea.scrollTop(top);
Try it here: http://jsfiddle.net/QGJeE/7/
Another solution(harder to imply as there is no unique cross-browser-way):
Instead of changing the value of the textarea create a textRange of the textarea's content and modify the ranges text.

contenteditable single-line input

For an application we're developing at the company where I work, we need an input that supports inserting emoticons inside our JS-based web app. We're currently using an input with the emoticon shortcodes (ie ':-)') and would like to switch to inserting actual, graphical images.
Our original plan was to use a contenteditable <div>. We're using listeners for the paste event as well as the different key/mouse interactions to ensure no unwanted markup enters the contenteditable (we strip text out of its container tags and leave only image tags that we inserted ourselves).
However, the problem right now is that the div resizes if you put in enough content (ie its height increases). We don't want this to happen, nor is it acceptable for the text to just be hidden (ie plain overflow: hidden). So:
Is there a way to make the contenteditable div behave like a single-line input?
I'd like it best if there is a relatively simple attribute/css property that I've missed that will do what I want, but if necessary CSS+JS suggestions will also be appreciated.
[contenteditable="true"].single-line {
white-space: nowrap;
width:200px;
overflow: hidden;
}
[contenteditable="true"].single-line br {
display:none;
}
[contenteditable="true"].single-line * {
display:inline;
white-space:nowrap;
}
<div contenteditable="true" class="single-line">
This should work.
</div>​
Other answers are wrong and contain few mistakes (on 2019-05-07). Other solutions suggest to use "white-space: nowrap" (prevents carrying to another line) + "overflow: hidden" (prevents long text going beyond the field) + hiding <br> and other.
First mistake in that solutions is "overflow: hidden" also prevents scrolling the text. User will not be able to scroll the text by:
Pressing mouse middle button
Selecting the text and moving mouse pointer to the left or right
Using horizontal mouse scroll (when user have such a thing)
The only way he can scroll is using keyboard arrows.
You can solve this problem by using "overflow: hidden" and "overflow: auto" (or "scroll") at the same time. You should create parent div with "overflow: hidden" to hide content user should not see. This element must have input borders and other design. And you should create child div with "overflow-x: auto" and "contenteditable" attribute. This element will have scrollbar so user can scroll it without any limitations and he will not see this scrollbar because of hiding overflow in parent element.
Example of solution:
document.querySelectorAll('.CETextInput').forEach(el => {
//Focusing on child element after clicking parent. We need it because parent element has bigger width than child.
el.parentNode.addEventListener('mousedown', function(e) {
if (e.target === this) {
setTimeout(() => this.children[0].focus(), 0);
}
});
//Prevent Enter. See purpose in "Step 2" in answer.
el.parentNode.addEventListener('keydown', function(e) {
if (e.keyCode === 13)
e.preventDefault();
});
});
.CETextInputBorder { /*This element is needed to prevent cursor: text on border*/
display: inline-block;
border: 1px solid #aaa;
}
.CETextInputCont {
overflow: hidden;
cursor: text; /*You must set it because parent elements is bigger then child contenteditable element. Also you must add javascript to focus child element on click parent*/
/*Style:*/
width: 10em;
height: 1em;
line-height: 1em;
padding: 5px;
font-size: 20px;
font-family: sans-serif;
}
.CETextInput {
white-space: pre; /*"pre" is like "nowrap" but displays all spaces correctly (with "nowrap" last space is not displayed in Firefox, tested on Firefox 66, 2019-05-15)*/
overflow-x: auto;
min-height: 100%; /*to prevent zero-height with no text*/
/*We will duplicate vertical padding to let user click contenteditable element on top and bottom. We would do same thing for horizontal padding but it is not working properly (in all browsers when scroll is in middle position and in Firefox when scroll is at the end). You can also replace vertical padding with just bigger line height.*/
padding: 5px 0;
margin-top: -5px;
outline: none; /*Prevent border on focus in some browsers*/
}
<div class="CETextInputBorder">
<div class="CETextInputCont">
<div class="CETextInput" contenteditable></div>
</div>
</div>
Step 2: Solving problem with <br> and other:
Also there is a problem that user or extensions can paste
<br> (can be pasted by user)
<img> (may have big size) (can be pasted by user)
elements with another "white-space" value
<div> and other elements that carry text to another line
elements with unsuitable "display" value
But advise to hide all <br> is wrong too. That is because Mozilla Firefox adds <br> element to empty field (I guess it may be workaround of bug with text cursor disappearing after deleting last character; checked in Firefox 66 released on 2019-03-19). If you hide this element then when user moves focus to field caret will be set in this hidden <br> element and text cursor will be hidden too (always).
You can fix this if you will be <br> when you know field is empty. You need some javascript here (you cannot use :empty selector because field contains <br> elements and not empty). Example of solution:
document.querySelectorAll('.CETextInput').forEach(el => {
//OLD CODE:
//Focusing on child element after clicking parent. We need it because parent element has bigger width than child.
el.parentNode.addEventListener('mousedown', function(e) {
if (e.target === this) {
setTimeout(() => this.children[0].focus(), 0);
}
});
//Prevent Enter to prevent blur on Enter
el.parentNode.addEventListener('keydown', function(e) {
if (e.keyCode === 13)
e.preventDefault();
});
//NEW CODE:
//Update "empty" class on all "CETextInput" elements:
updateEmpty.call(el); //init
el.addEventListener('input', updateEmpty);
function updateEmpty(e) {
const s = this.innerText.replace(/[\r\n]+/g, ''); //You must use this replace, see explanation below in "Step 3"
this.classList.toggle('empty', !s);
}
});
/*OLD CODE:*/
.CETextInputBorder { /*This element is needed to prevent cursor: text on border*/
display: inline-block;
border: 1px solid #aaa;
}
.CETextInputCont {
overflow: hidden;
cursor: text; /*You must set it because parent elements is bigger then child contenteditable element. Also you must add javascript to focus child element on click parent*/
/*Style:*/
width: 10em;
height: 1em;
line-height: 1em;
padding: 5px;
font-size: 20px;
font-family: sans-serif;
}
.CETextInput {
white-space: pre; /*"pre" is like "nowrap" but displays all spaces correctly (with "nowrap" last space is not displayed in Firefox, tested on Firefox 66, 2019-05-15)*/
overflow-x: auto;
min-height: 100%; /*to prevent zero-height with no text*/
/*We will duplicate vertical padding to let user click contenteditable element on top and bottom. We would do same thing for horizontal padding but it is not working properly (in all browsers when scroll is in middle position and in Firefox when scroll is at the end). You can also replace vertical padding with just bigger line height.*/
padding: 5px 0;
margin-top: -5px;
outline: none; /*Prevent border on focus in some browsers*/
}
/*NEW CODE:*/
.CETextInput:not(.empty) br,
.CETextInput img { /*We hide <img> here. If you need images do not hide them but set maximum height. User can paste image by pressing Ctrl+V or Ctrl+Insert.*/
display: none;
}
.CETextInput * {
display: inline;
white-space: pre;
}
<!--OLD CODE:-->
<div class="CETextInputBorder">
<div class="CETextInputCont">
<div class="CETextInput" contenteditable></div>
</div>
</div>
Step 3: Solving problem with getting value:
We hided <br> elements so "innerText" value will not contain them. But:
When "empty" class is set result may contain <br> elements.
Your other styles or extensions may override "display: none" by "!important" mark or by rule with higher priority.
So when you get value you should make replace to avoid accidental getting line breaks:
s = s.replace(/[\r\n]+/g, '');
Do not use javascript for hiding <br>
Also you could solve the problem with <br> by removing them by javascript but this is very bad solution because after every removing user cannot use "undo" action anymore for canceling changes was made before removing.
Also you could use document.execCommand('delete') to delete <br> but it is hard to implement + user can undo your deletion and restore <br> elements.
Adding placeholder
It was not asked in question but I guess many people using single-line contenteditable elements will need it. Here is example how to make placeholder using css and "empty" class we talked above:
//OLD CODE:
document.querySelectorAll('.CETextInput').forEach(el => {
//Focusing on child element after clicking parent. We need it because parent element has bigger width than child.
el.parentNode.addEventListener('mousedown', function(e) {
if (e.target === this) {
setTimeout(() => this.children[0].focus(), 0);
}
});
//Prevent Enter to prevent blur on Enter
el.parentNode.addEventListener('keydown', function(e) {
if (e.keyCode === 13)
e.preventDefault();
});
//Update "empty" class on all "CETextInput" elements:
updateEmpty.call(el); //init
el.addEventListener('input', updateEmpty);
function updateEmpty(e) {
const s = this.innerText.replace(/[\r\n]+/g, ''); //You must use this replace, see explanation below in "Step 3"
this.classList.toggle('empty', !s);
//NEW CODE:
//Make element always have <br>. See description in html. I guess it is not needed because only Firefox has bug with bad cursor position but Firefox always adds this element by itself except on init. But on init we are adding it by ourselves (see html).
if (!s && !Array.prototype.filter.call(this.children, el => el.nodeName === 'BR').length)
this.appendChild(document.createElement('br'));
}
});
/*OLD CODE:*/
.CETextInputBorder { /*This element is needed to prevent cursor: text on border*/
display: inline-block;
border: 1px solid #aaa;
}
.CETextInputCont {
overflow: hidden;
cursor: text; /*You must set it because parent elements is bigger then child contenteditable element. Also you must add javascript to focus child element on click parent*/
/*Style:*/
width: 10em;
height: 1em;
line-height: 1em;
padding: 5px;
font-size: 20px;
font-family: sans-serif;
}
.CETextInput {
white-space: pre; /*"pre" is like "nowrap" but displays all spaces correctly (with "nowrap" last space is not displayed in Firefox, tested on Firefox 66, 2019-05-15)*/
overflow-x: auto;
min-height: 100%; /*to prevent zero-height with no text*/
/*We will duplicate vertical padding to let user click contenteditable element on top and bottom. We would do same thing for horizontal padding but it is not working properly (in all browsers when scroll is in middle position and in Firefox when scroll is at the end).

padding: 5px 0;
margin-top: -5px;

Solution with only one div and "scrollbar-width"
You can also use only one div by setting "overflow-x: auto", "overflow-y: hidden" and "scrollbar-width: none". But "scrollbar-width" is new property and works only in Firefox 64+ and no other browsers yet.
You can also add:
webkit-prefixed version: "-webkit-scrollbar-width: none"
non-standardized ".CETextInput::-webkit-scrollbar { display: none; }" (for webkit-based browsers)
"-ms-overflow-style: none"
I would not recommend to use this solution, but here is example:
//OLD CODE:
document.querySelectorAll('.CETextInput').forEach(el => {
//Focusing on child is not needed anymore
//Prevent Enter to prevent blur on Enter
el.addEventListener('keydown', function(e) {
if (e.keyCode === 13)
e.preventDefault();
});
//Update "empty" class on all "CETextInput" elements:
updateEmpty.call(el); //init
el.addEventListener('input', updateEmpty);
function updateEmpty(e) {
const s = this.innerText.replace(/[\r\n]+/g, ''); //You must use this replace, see explanation below in "Step 3"
this.classList.toggle('empty', !s);
}
});
/*NEW CODE:*/
.CETextInput {
white-space: pre; /*"pre" is like "nowrap" but displays all spaces correctly (with "nowrap" last space is not displayed in Firefox, tested on Firefox 66, 2019-05-15)*/
overflow-x: auto; /*or "scroll"*/
overflow-y: hidden;
-webkit-scrollbar-width: none; /*Chrome 4+ (probably), webkit based*/
scrollbar-width: none; /*FF 64+, Chrome ??+, webkit based, Edge ??+*/
-ms-overflow-style: none; /*IE ??*/
/*Style:*/
width: 10em;
height: 1em;
line-height: 1em;
padding: 5px;
border: 1px solid #aaa;
font-size: 20px;
font-family: sans-serif;
}
.CETextInput::-webkit-scrollbar {
display: none; /*Chrome ??, webkit based*/
}
/*OLD CODE:*/
.CETextInput:not(.empty) br,
.CETextInput img { /*We hide <img> here. If you need images do not hide them but set maximum height. User can paste image by pressing Ctrl+V or Ctrl+Insert.*/
display: none;
}
.CETextInput * {
display: inline;
white-space: pre;
}
<!--NEW CODE:-->
<div class="CETextInput" contenteditable></div>
This solution has 3 problems with paddings:
In Firefox (tested on 2019-05-11, Firefox 66) there is no right padding when long text is typed. That is because Firefox does not display bottom or right padding when using padding in the same element that have scrollbar and when content is scrolled to the end.
In all browsers there is no padding when scrolling long text in middle position. It looks worse. <input type="text"> does not have this problem.
When user press home or end browsers scroll to place paddings are not visible.
To solve these problems you need use 3 elements like we used before but in this case you don't need use scrollbar-width. Our solution with 3 elements does not have these problems.
Other problems (in every solution):
Blur on pasting text ends with line break. I will think how to fix it.
When using paddings this.children[0].focus() is not enough in webkit-based browsers (cursor position is not where user clicked). I will think how to fix it.
Firefox (tested on 2019-05-11, Firefox 66): When short text is typed user cannot select last word by double clicking on the right of it. I will think about it.
When user starts text selection in the page he can end it in our field. Usual <input type="text"> does not have this behavior. But I don't think it is critical.
I think you are looking for a contenteditable div with only one line of text that scrolls horizontally when it overflows the div. This should do the trick: http://jsfiddle.net/F6C9T/1
div {
font-family: Arial;
font-size: 18px;
min-height: 40px;
width: 300px;
border: 1px solid red;
overflow: hidden;
white-space: nowrap;
}
<div contenteditable>
Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas.
</div>
The min-height: 40px incorporates the height for when the horizontal scroll bar appears. A min-height:20px would automatically expand when the horizontal scroll bar appears, but this doesn't work in IE7 (though you could use conditional comments to apply separate styling if you wanted it).
I adapted the #tw16 accepted solution (on 5th Dec 2019) to add in scrolling. The trick was to add scrolling using overflow-x: auto but then hide the scrollbar (https://stackoverflow.com/a/49278385)
/* Existing Solution */
[contenteditable="true"].single-line {
white-space: nowrap;
width: 200px;
overflow: hidden;
}
[contenteditable="true"].single-line br {
display:none;
}
[contenteditable="true"].single-line * {
display:inline;
white-space:nowrap;
}
/* Make Scrollable */
[contenteditable="true"].single-line {
overflow-x: auto;
overflow-y: hidden;
scrollbar-width: none; /* Firefox */
-ms-overflow-style: none; /* Internet Explorer 10+ */
}
[contenteditable="true"].single-line::-webkit-scrollbar { /* WebKit */
width: 0;
height: 0;
}
<div contenteditable="true" class="single-line">
This should scroll when you have really long text!
</div>​
Here's a relatively simple solution that uses the contenteditable's input event to scan the dom and filter out various flavors of new lines (so it should be robust against copy/paste, drag 'n drop, hitting enter on the keyboard, etc). It condenses multiple TextNodes into single TextNodes, strips newlines from TextNodes, kills BRs, and puts a "display: inline" on any other element that it touches. Tested on Chrome, no guarantees anywhere else.
var editable = $('#editable')
editable.on('input', function() {
return filter_newlines(editable);
});
function filter_newlines(div) {
var node, prev, _i, _len, _ref, _results;
prev = null;
_ref = div.contents();
_results = [];
for (_i = 0, _len = _ref.length; _i < _len; _i++) {
node = _ref[_i];
if (node.nodeType === 3) {
node.nodeValue = node.nodeValue.replace('\n', '');
if (prev) {
node.nodeValue = prev.nodeValue + node.nodeValue;
$(prev).remove();
}
_results.push(prev = node);
} else if (node.tagName.toLowerCase() === 'br') {
_results.push($(node).remove());
} else {
$(node).css('display', 'inline');
filter_newlines($(node));
_results.push(prev = null);
}
}
return _results;
}
#editable {
width: 200px;
height: 20px;
border: 1px solid black;
}
<div id="editable" contenteditable="true"></div>
Or here's the fiddle: http://jsfiddle.net/tG9Qa/
If you want a different way of solving it other than changing the requirements, with a little display:table it is fully possible =)
.container1 {
height:20px;
width:273px;
overflow:hidden;
border:1px solid green;
}
.container2 {
display:table;
}
.textarea {
width:273px;
font-size: 18px;
font-weight: normal;
line-height: 18px;
outline: none;
display: table-cell;
position: relative;
-webkit-user-select: text;
-moz-user-select: text;
-ms-user-select: text;
user-select: text;
word-wrap: break-word;
overflow:hidden;
}
<div class="container1">
<div class="container2">
<div contenteditable="true" class="textarea"></div>
</div>
</div>
So, for posterity: the simplest solution is to get your product manager to change the requirements so you can do multiline editing. This is what ended up happening in our case.
However, before that happened, I ended up going quite a way in creating a manually moving single-line richtext editor. I wrapped it up in a jQuery plugin in the end. I don't have time to finish it up (there are probably bugs in IE, Firefox works best and Chrome works pretty well - comments are sparse and sometimes not very clear). It uses parts of the Rangy library (extracted because I didn't want to rely on the complete library) to get screen positions of selections in order to test for mouse position vs. selection (so you can drag selections and move the box).
Roughly, it works by using 3 elements. An outer div (the thing you call the plugin on), which gets overflow: hidden, and then 2 levels of nesting inside it. The first level is absolutely positioned, the second level is the actual contenteditable. This separation is necessary because otherwise some browsers will give the contenteditable absolutely positioned element grippies, to let the user move it around...
In any case, then there is a whole bunch of code to move the absolutely positioned element around inside the top element, thus moving the actual contenteditable. The contenteditable itself has white-space nowrap, etc. etc. to force it to stay a single line.
There is also code in the plugin that strips out anything that isn't an image (like br, tables, etc. etc.) from any text that's pasted / dragged into the box. You need some parts of this (like the brs, stripping/normalizing paragraphs, etc.) but maybe you would normally want to keep links, em, strong and/or some other formatting.

Check out this answer I just posted. This should help you out:
How to create a HTML5 single line contentEditable tab which listens to Enter and Esc
Here is the HTML markup:
<span contenteditable="false"></span>
Here is the jQuery/javascript:
$(document).ready(function() {
$('[contenteditable]').dblclick(function() {
$(this).attr('contenteditable', 'true');
clearSelection();
$(this).trigger('focus');
});
$('[contenteditable]').live('focus', function() {
before = $(this).text();
if($(this).attr('contenteditable') == "true") { $(this).css('border', '1px solid #ffd646'); }
//}).live('paste', function() {
}).live('blur', function() {
$(this).attr('contenteditable', 'false');
$(this).css('border', '1px solid #fafafa');
$(this).text($(this).text().replace(/(\r\n|\n|\r)/gm,""));
if (before != $(this).text()) { $(this).trigger('change'); }
}).live('keyup', function(event) {
// ESC=27, Enter=13
if (event.which == 27) {
$(this).text(before);
$(this).trigger('blur');
} else if (event.which == 13) {
$(this).trigger('blur');
}
});
$('[contenteditable]').live('change', function() {
var $thisText = $(this).text();
//Do something with the new value.
});
});
function clearSelection() {
if ( document.selection ) {
document.selection.empty();
} else if ( window.getSelection ) {
window.getSelection().removeAllRanges();
}
}
Hope this helps someone!!!
You can replace this div with text input (after onclick event is called).
I have used something similar to this plugin and it worked fine.
with jQuery I have set a .keypress event and then tests for e.keyCode == 13 (return key) and if is return false from the event and the editing is not able to make multilines
$('*[contenteditable=yes]').keypress(function(e) {
if(e.keyCode == 13 && !$(this).data('multiline')) {
return false;
}
})
