The idea is this -
There is a contenteditable element with some text in it. Am trying to build out a tagging mechanism (kind of like twitter's people tagging when you type '#'). Whenever a user types '#', it shows up a popover with suggestions and filters when they continue typing. Until here it's easy and I have got it figured out. The problem comes when I need to show the popover if/only if the caret is over the element containing the tag.
<div contenteditable="">
<p>Some random text before
<a href="javascript:;"
class="name-suggest"
style="color:inherit !important;text-decoration:inherit !important">#samadams</a>
Some random text after</p>
</div>
Now, whenever the user moves the caret over the a tag / clicks on it, I want to trigger an event that shows the popover, and remove it whenever the caret leaves the a tag. (kind of like focus / blur but they don't seem to work). onmousedown works but there is no way to tell if the cursor has been moved into the anchor tag with the keyboard.
Also, am doing this in angularjs, so, any solution targeted towards that would be preferable but not necessary.
Have been trying to get this to work for a day and any help is greatly appreciated.
This will let you know when your caret position is in an anchor node containing an #
$('#content').on('mouseup keydown keyup', function (event) {
var sel = getSelection();
if (sel.type === "Caret") {
var anchorNodeVal = sel.anchorNode.nodeValue;
if ( anchorNodeVal.indexOf('#') >= 0) {
$('#pop').show()
} else {
$('#pop').hide()
}
}
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="content" contenteditable="">
<p>Some random text before
<a href="javascript:;"
class="name-suggest"
style="color:inherit !important;text-decoration:inherit !important">#samadams</a>
Some random text after</p>
</div>
<div id="pop" style="display:none">Twitter node found</div>
You could add some regex to further validate the selection.
There is a weird move with RegExps and offset calculation in the code below, but let me explain why it's a better solution.
I've been building a complicated editor using contenteditable about a year ago. It wasn't just a disaster. It was a fucking disaster. There is no cover-all-the-cases spec. Browsers behave differently in every possible detail and it changes frequently. Put a caret before # char and you will get this is Gecko:
<a href="#">|#name
And this in WebKit:
|<a href="#">#name
Well, unless <a> is paragraph's first child. Then result would be the same as in Gecko. Try to put caret after the nickname and both will tell it's inside the link. Start typing, and caret will pop out the element - a year ago Gecko wasn't doing it.
I've used native Selection & Range APIs in this example, they are IE9+. You may want to use Rangy instead.
$el = $('#content');
var showTip = function (nickname) {
// ...
console.log('Show: ' + nickname);
};
var dismissTip = function () {
// ...
console.log('Hide');
};
// I'm sure there is a better RegExp for this :)
var nicknameRegexp = /(^|\b|\s)\#(\w+)(\s|\b|$)/g;
var trackSelection = function () {
var selection = window.getSelection(),
range = selection.rangeCount > 0 ? selection.getRangeAt(0) : null;
if (range == null || $el[0].contains(range.commonAncestorContainer) == false) {
return dismissTip();
}
var comparer = range.cloneRange();
comparer.setStart($el[0], 0);
var offset = comparer.toString().length;
var match, from, to;
while (match = nicknameRegexp.exec($el[0].textContent)) {
from = match.index + match[1].length;
to = match.index + match[1].length + match[2].length + 1;
if (offset >= from && offset <= to) {
// Force rewind, otherwise next time result might be incorrect
nicknameRegexp.lastIndex = 0;
return showTip(match[2]);
}
}
return dismissTip();
};
$el.on({
// `mousedown` can happen outside #content
'mousedown': function (e) {
$(document).one('mouseup', function (e) {
// Calling function without a tiny delay will lead to a wrong selection info
setTimeout(trackSelection, 5);
});
},
'keyup': trackSelection
});
Just looked at Fire event when caret enters span element which led me here, pretending your case was quite similar except finding if current word is specifically beginning with # for the modal to show...
The thing you need is a way to get the word we're on at the moment we move or type, then check the first character and hide/show the modal pane accordingly will be pretty easy.
function getSelectedWord(grab=document.getSelection()) {
var i = grab.focusOffset, node = grab.focusNode, // find cursor
text = node.data || node.innerText, // get focus-node text
a = text.substr(0, i), p = text.substr(i); // split on caret
return a.split(/\s/).pop() + p.split(/\s/)[0]} // cut-out at spaces
Now you can listen for keydown or selectionchange events and show your pane knowning what have already been written of the current/selected word.
editor.addEventListener('keydown', ev => {
if (ev.key.substr(0, 5) != 'Arrow') // react when we move caret or
if (ev.key != '#') return; // react when we type an '#' or quit
var word = getSelectedWord(); // <-- checking value
if (word[0] == '#') showModal(word.substr(1)); // pass without '#'
});
Note that social networks and code completion usually stops at caret position while I did check for word tail... You can go usual by removing p off of getSelectedWord function definition if desired.
Hope this still helps; Happy coding ! ;)
I have a paragraph of text in which the user may place a "pin" to mark a position. Once a pin has been placed, I would like to allow the user to move its position by dragging it to a new location in the paragraph. This is simple to do with block elements, but I have yet to see a good way to do it with inline elements. How might I accomplish this?
I have already implemented it using window.selection as a way to find the cursor's location in the paragraph, but it is not as smooth as I would like.
As a note, I am using the Rangy library to wrap the native Range and Selection functionality, but it works the same way as the native functions do.
Here is the code:
$(document).on("mousedown", '.pin', function () {
//define what a pin is
var el = document.createElement("span");
el.className = "pin";
el.id = "test";
//make it contain an empty space so we can color it
el.appendChild(document.createTextNode("d"));
$(document).on("mousemove", function () {
//get the current selection
var selection = rangy.getSelection();
//collapse the selection to either the front
//or back, since we do not want the user to see it.
if (selection.isBackwards()) {
selection.collapseToStart();
} else {
selection.collapseToEnd();
}
//remove the old pin
$('.pin').remove();
//place the new pin at the current selection
selection.getAllRanges()[0].insertNode(el);
});
//remove the handler when the user has stopped dragging it
$(document).on("mouseup", function () {
$(document).off("mousemove");
});
});
And here is a working demo: http://jsfiddle.net/j1LLmr5b/22/ .
As you can see, it works(usually), but the user can see the selection being made. Have any ideas on how to move the span without showing the selection highlight? I will also accept an alternate method that does not use the selection at all. The goal is to allow movement of the span as cleanly as possible.
You can do this using ranges instead using code similar to this answer. Unfortunately the code is a bit longer than ideal because IE hasn't yet implemented document.caretPositionFromPoint(). However, the old proprietary TextRange object, still present in IE 11, comes to the rescue.
Here's a demo:
http://jsfiddle.net/j1LLmr5b/26/
Here's the relevant code:
var range, textRange, x = e.clientX, y = e.clientY;
//remove the old pin
$('.pin').remove();
// Try the standards-based way first
if (document.caretPositionFromPoint) {
var pos = document.caretPositionFromPoint(x, y);
range = document.createRange();
range.setStart(pos.offsetNode, pos.offset);
range.collapse();
}
// Next, the WebKit way
else if (document.caretRangeFromPoint) {
range = document.caretRangeFromPoint(x, y);
}
// Finally, the IE way
else if (document.body.createTextRange) {
textRange = document.body.createTextRange();
textRange.moveToPoint(x, y);
var spanId = "temp_" + ("" + Math.random()).slice(2);
textRange.pasteHTML('<span id="' + spanId + '"> </span>');
var span = document.getElementById(spanId);
//place the new pin
span.parentNode.replaceChild(el, span);
}
if (range) {
//place the new pin
range.insertNode(el);
}
Try this my friend
el.appendChild(document.createTextNode("d"));
You have create empty span tag that's why you found empty.
add after
el.id = "test";
this
var value = $('.pin').text();
$(el).text(value);
You can hide selection with css
::selection {color:red;background:yellow;}
::-moz-selection {color:red;background:yellow;}
that's all how i can help for a now
I'm looking to move the caret exactly four spaces ahead of its current position so that I can insert a tab properly. I've already got the HTML insertion at the caret's position working, but when I insert the HTML, the caret is left behind. I've spent the past hour or so looking at various ways to do this and I've tried plenty of them, but I can't get any of them to work for me. Here's the most recent method I've tried:
function moveCaret(input, distance) {
if(input.setSelectionRange) {
input.focus();
input.setSelectionRange(distance, distance);
} else if(input.createTextRange) {
var range = input.createTextRange();
range.collapse(true);
range.moveEnd(distance);
range.moveStart(distance);
range.select();
}
}
It does absolutely nothing--doesn't move the caret, throw any errors or anything. This leaves me baffled. And yes, I know that the above method set (is supposed to) set the caret at a certain position from the beginning of the specified node (that is, input), but even that's not working. So, what exactly am I doing wrong, and how can I do it right?
Edit: Based on the links that o.v. provided, I've managed to cobble something together that's finally doing something: throwing an error. Yay! Here's the new code:
this.moveCaret = function(distance) {
if(that.win.getSelection) {
var range = that.win.getSelection().getRangeAt(0);
range.setStart(range.startOffset + distance);
} else if (that.win.document.selection) {
var range = that.win.document.selection.createRange();
range.setStart(range.startOffset + distance);
}
}
Now, this gives the error Uncaught Error: NOT_FOUND_ERR: DOM Exception 8. Any ideas why?
The code snippet you have is for text inputs and textareas, not contenteditable elements.
Provided that all your content is in a single text node and the selection is completely contained within it, the following will work in all major browsers, including IE 6.
Demo: http://jsfiddle.net/9sdrZ/
Code:
function moveCaret(win, charCount) {
var sel, range;
if (win.getSelection) {
// IE9+ and other browsers
sel = win.getSelection();
if (sel.rangeCount > 0) {
var textNode = sel.focusNode;
var newOffset = sel.focusOffset + charCount;
sel.collapse(textNode, Math.min(textNode.length, newOffset));
}
} else if ( (sel = win.document.selection) ) {
// IE <= 8
if (sel.type != "Control") {
range = sel.createRange();
range.move("character", charCount);
range.select();
}
}
}
What is the best way (and I presume simplest way) to place the cursor at the end of the text in a input text element via JavaScript - after focus has been set to the element?
There's a simple way to get it working in most browsers.
this.selectionStart = this.selectionEnd = this.value.length;
However, due to the *quirks of a few browsers, a more inclusive answer looks more like this
setTimeout(function(){ that.selectionStart = that.selectionEnd = 10000; }, 0);
Using jQuery (to set the listener, but it's not necessary otherwise)
$('#el').focus(function(){
var that = this;
setTimeout(function(){ that.selectionStart = that.selectionEnd = 10000; }, 0);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id='el' type='text' value='put cursor at end'>
Using Vanilla JS (borrowing addEvent function from this answer)
// Basic cross browser addEvent
function addEvent(elem, event, fn){
if(elem.addEventListener){
elem.addEventListener(event, fn, false);
}else{
elem.attachEvent("on" + event,
function(){ return(fn.call(elem, window.event)); });
}}
var element = document.getElementById('el');
addEvent(element,'focus',function(){
var that = this;
setTimeout(function(){ that.selectionStart = that.selectionEnd = 10000; }, 0);
});
<input id='el' type='text' value='put cursor at end'>
Quirks
Chrome has an odd quirk where the focus event fires before the cursor is moved into the field; which screws my simple solution up. Two options to fix this:
You can add a timeout of 0 ms (to defer the operation until the stack is clear)
You can change the event from focus to mouseup. This would be pretty annoying for the user unless you still kept track of focus. I'm not really in love with either of these options.
Also, #vladkras pointed out that some older versions of Opera incorrectly calculate the length when it has spaces. For this you can use a huge number that should be larger than your string.
Try this, it has worked for me:
//input is the input element
input.focus(); //sets focus to element
var val = this.input.value; //store the value of the element
this.input.value = ''; //clear the value of the element
this.input.value = val; //set that value back.
For the cursor to be move to the end, the input has to have focus first, then when the value is changed it will goto the end. If you set .value to the same, it won't change in chrome.
I faced this same issue (after setting focus through RJS/prototype) in IE.
Firefox was already leaving the cursor at the end when there is already a value for the field. IE was forcing the cursor to the beginning of the text.
The solution I arrived at is as follows:
<input id="search" type="text" value="mycurrtext" size="30"
onfocus="this.value = this.value;" name="search"/>
This works in both IE7 and FF3 but doesn't work in modern browsers (see comments) as it is not specified that UA must overwrite the value in this case (edited in accordance with meta policy).
After hacking around with this a bit, I found the best way was to use the setSelectionRange function if the browser supports it; if not, revert to using the method in Mike Berrow's answer (i.e. replace the value with itself).
I'm also setting scrollTop to a high value in case we're in a vertically-scrollable textarea. (Using an arbitrary high value seems more reliable than $(this).height() in Firefox and Chrome.)
I've made it is as a jQuery plugin. (If you're not using jQuery I trust you can still get the gist easily enough.)
I've tested in IE6, IE7, IE8, Firefox 3.5.5, Google Chrome 3.0, Safari 4.0.4, Opera 10.00.
It's available on jquery.com as the PutCursorAtEnd plugin. For your convenience, the code for release 1.0 is as follows:
// jQuery plugin: PutCursorAtEnd 1.0
// http://plugins.jquery.com/project/PutCursorAtEnd
// by teedyay
//
// Puts the cursor at the end of a textbox/ textarea
// codesnippet: 691e18b1-f4f9-41b4-8fe8-bc8ee51b48d4
(function($)
{
jQuery.fn.putCursorAtEnd = function()
{
return this.each(function()
{
$(this).focus()
// If this function exists...
if (this.setSelectionRange)
{
// ... then use it
// (Doesn't work in IE)
// Double the length because Opera is inconsistent about whether a carriage return is one character or two. Sigh.
var len = $(this).val().length * 2;
this.setSelectionRange(len, len);
}
else
{
// ... otherwise replace the contents with itself
// (Doesn't work in Google Chrome)
$(this).val($(this).val());
}
// Scroll to the bottom, in case we're in a tall textarea
// (Necessary for Firefox and Google Chrome)
this.scrollTop = 999999;
});
};
})(jQuery);
<script type="text/javascript">
function SetEnd(txt) {
if (txt.createTextRange) {
//IE
var FieldRange = txt.createTextRange();
FieldRange.moveStart('character', txt.value.length);
FieldRange.collapse();
FieldRange.select();
}
else {
//Firefox and Opera
txt.focus();
var length = txt.value.length;
txt.setSelectionRange(length, length);
}
}
</script>
This function works for me in IE9, Firefox 6.x, and Opera 11.x
It's 2019 and none of the methods above worked for me, but this one did, taken from https://css-tricks.com/snippets/javascript/move-cursor-to-end-of-input/
function moveCursorToEnd(id) {
var el = document.getElementById(id)
el.focus()
if (typeof el.selectionStart == "number") {
el.selectionStart = el.selectionEnd = el.value.length;
} else if (typeof el.createTextRange != "undefined") {
var range = el.createTextRange();
range.collapse(false);
range.select();
}
}
<input id="myinput" type="text" />
Move cursor to end
I've tried the following with quite great success in chrome
$("input.focus").focus(function () {
var val = this.value,
$this = $(this);
$this.val("");
setTimeout(function () {
$this.val(val);
}, 1);
});
Quick rundown:
It takes every input field with the class focus on it, then stores the old value of the input field in a variable, afterwards it applies the empty string to the input field.
Then it waits 1 milisecond and puts in the old value again.
el.setSelectionRange(-1, -1);
https://codesandbox.io/s/peaceful-bash-x2mti
This method updates the HTMLInputElement.selectionStart, selectionEnd,
and selectionDirection properties in one call.
https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement/setSelectionRange
In other js methods -1 usually means (to the) last character. This is the case for this one too, but I couldn't find explicit mention of this behavior in the docs.
Simple. When editing or changing values, first put the focus then set value.
$("#catg_name").focus();
$("#catg_name").val(catg_name);
Still the intermediate variable is needed, (see var val=)
else the cursor behaves strange, we need it at the end.
<body onload="document.getElementById('userinput').focus();">
<form>
<input id="userinput" onfocus="var val=this.value; this.value=''; this.value= val;"
class=large type="text" size="10" maxlength="50" value="beans" name="myinput">
</form>
</body>
const end = input.value.length
input.setSelectionRange(end, end)
// 👇 scroll to the bottom if a textarea has long text
input.focus()
Try this one works with Vanilla JavaScript.
<input type="text" id="yourId" onfocus="let value = this.value; this.value = null; this.value=value" name="nameYouWant" class="yourClass" value="yourValue" placeholder="yourPlaceholder...">
In Js
document.getElementById("yourId").focus()
For all browsers for all cases:
function moveCursorToEnd(el) {
window.setTimeout(function () {
if (typeof el.selectionStart == "number") {
el.selectionStart = el.selectionEnd = el.value.length;
} else if (typeof el.createTextRange != "undefined") {
var range = el.createTextRange();
range.collapse(false);
range.select();
}
}, 1);
}
Timeout required if you need to move cursor from onFocus event handler
I like the accepted answer a lot, but it stopped working in Chrome. In Chrome, for the cursor to go to the end, input value needs to change. The solution is as follow:
<input id="search" type="text" value="mycurrtext" size="30"
onfocus="var value = this.value; this.value = null; this.value = value;" name="search"/>
document.querySelector('input').addEventListener('focus', e => {
const { value } = e.target;
e.target.setSelectionRange(value.length, value.length);
});
<input value="my text" />
In jQuery, that's
$(document).ready(function () {
$('input').focus(function () {
$(this).attr('value',$(this).attr('value'));
}
}
I just found that in iOS, setting textarea.textContent property will place the cursor at the end of the text in the textarea element every time. The behavior was a bug in my app, but seems to be something that you could use intentionally.
This problem is interesting. The most confusing thing about it is that no solution I found solved the problem completely.
+++++++ SOLUTION +++++++
You need a JS function, like this:
function moveCursorToEnd(obj) {
if (!(obj.updating)) {
obj.updating = true;
var oldValue = obj.value;
obj.value = '';
setTimeout(function(){ obj.value = oldValue; obj.updating = false; }, 100);
}
}
You need to call this guy in the onfocus and onclick events.
<input type="text" value="Test Field" onfocus="moveCursorToEnd(this)" onclick="moveCursorToEnd(this)">
IT WORKS ON ALL DEVICES AN BROWSERS!!!!
var valsrch = $('#search').val();
$('#search').val('').focus().val(valsrch);
Taking some of the answers .. making a single-line jquery.
$('#search').focus().val($('#search').val());
If the input field just needs a static default value I usually do this with jQuery:
$('#input').focus().val('Default value');
This seems to work in all browsers.
While this may be an old question with lots of answers, I ran across a similar issue and none of the answers were quite what I wanted and/or were poorly explained. The issue with selectionStart and selectionEnd properties is that they don't exist for input type number (while the question was asked for text type, I reckon it might help others who might have other input types that they need to focus). So if you don't know whether the input type the function will focus is a type number or not, you cannot use that solution.
The solution that works cross browser and for all input types is rather simple:
get and store the value of input in a variable
focus the input
set the value of input to the stored value
That way the cursor is at the end of the input element.
So all you'd do is something like this (using jquery, provided the element selector that one wishes to focus is accessible via 'data-focus-element' data attribute of the clicked element and the function executes after clicking on '.foo' element):
$('.foo').click(function() {
element_selector = $(this).attr('data-focus-element');
$focus = $(element_selector);
value = $focus.val();
$focus.focus();
$focus.val(value);
});
Why does this work? Simply, when the .focus() is called, the focus will be added to the beginning of the input element (which is the core problem here), ignoring the fact, that the input element already has a value in it. However, when the value of an input is changed, the cursor is automatically placed at the end of the value inside input element. So if you override the value with the same value that had been previously entered in the input, the value will look untouched, the cursor will, however, move to the end.
Super easy (you may have to focus on the input element)
inputEl = getElementById('inputId');
var temp = inputEl.value;
inputEl.value = '';
inputEl.value = temp;
Set the cursor when click on text area to the end of text...
Variation of this code is...ALSO works! for Firefox, IE, Safari, Chrome..
In server-side code:
txtAddNoteMessage.Attributes.Add("onClick", "sendCursorToEnd('" & txtAddNoteMessage.ClientID & "');")
In Javascript:
function sendCursorToEnd(obj) {
var value = $(obj).val(); //store the value of the element
var message = "";
if (value != "") {
message = value + "\n";
};
$(obj).focus().val(message);
$(obj).unbind();
}
If you set the value first and then set the focus, the cursor will always appear at the end.
$("#search-button").click(function (event) {
event.preventDefault();
$('#textbox').val('this');
$("#textbox").focus();
return false;
});
Here is the fiddle to test
https://jsfiddle.net/5on50caf/1/
I wanted to put cursor at the end of a "div" element where contenteditable = true, and I got a solution with Xeoncross code:
<input type="button" value="Paste HTML" onclick="document.getElementById('test').focus(); pasteHtmlAtCaret('<b>INSERTED</b>'); ">
<div id="test" contenteditable="true">
Here is some nice text
</div>
And this function do magic:
function pasteHtmlAtCaret(html) {
var sel, range;
if (window.getSelection) {
// IE9 and non-IE
sel = window.getSelection();
if (sel.getRangeAt && sel.rangeCount) {
range = sel.getRangeAt(0);
range.deleteContents();
// Range.createContextualFragment() would be useful here but is
// non-standard and not supported in all browsers (IE9, for one)
var el = document.createElement("div");
el.innerHTML = html;
var frag = document.createDocumentFragment(), node, lastNode;
while ( (node = el.firstChild) ) {
lastNode = frag.appendChild(node);
}
range.insertNode(frag);
// Preserve the selection
if (lastNode) {
range = range.cloneRange();
range.setStartAfter(lastNode);
range.collapse(true);
sel.removeAllRanges();
sel.addRange(range);
}
}
} else if (document.selection && document.selection.type != "Control") {
// IE < 9
document.selection.createRange().pasteHTML(html);
}
}
Works fine for most browsers, please check it, this code puts text and put focus at the end of the text in div element (not input element)

Thanks, Xeoncross
I also faced same problem. Finally this gonna work for me:
jQuery.fn.putCursorAtEnd = = function() {
return this.each(function() {
// Cache references
var $el = $(this),
el = this;
// Only focus if input isn't already
if (!$el.is(":focus")) {
$el.focus();
}
// If this function exists... (IE 9+)
if (el.setSelectionRange) {
// Double the length because Opera is inconsistent about whether a carriage return is one character or two.
var len = $el.val().length * 2;
// Timeout seems to be required for Blink
setTimeout(function() {
el.setSelectionRange(len, len);
}, 1);
} else {
// As a fallback, replace the contents with itself
// Doesn't work in Chrome, but Chrome supports setSelectionRange
$el.val($el.val());
}
// Scroll to the bottom, in case we're in a tall textarea
// (Necessary for Firefox and Chrome)
this.scrollTop = 999999;
});
};
This is how we can call this:
var searchInput = $("#searchInputOrTextarea");
searchInput
.putCursorAtEnd() // should be chainable
.on("focus", function() { // could be on any event
searchInput.putCursorAtEnd()
});
It's works for me in safari, IE, Chrome, Mozilla. On mobile devices I didn't tried this.
Check this solution!
//fn setCurPosition
$.fn.setCurPosition = function(pos) {
this.focus();
this.each(function(index, elem) {
if (elem.setSelectionRange) {
elem.setSelectionRange(pos, pos);
} else if (elem.createTextRange) {
var range = elem.createTextRange();
range.collapse(true);
range.moveEnd('character', pos);
range.moveStart('character', pos);
range.select();
}
});
return this;
};
// USAGE - Set Cursor ends
$('#str1').setCurPosition($('#str1').val().length);
// USAGE - Set Cursor at 7 position
// $('#str2').setCurPosition(7);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<p>Set cursor at any position</p>
<p><input type="text" id="str1" value="my string here" /></p>
<p><input type="text" id="str2" value="my string here" /></p>
I took the best answers from here, and created a function that works well in Chrome.
You will need to wrap the logic in a timeout, because you have to wait for the focus to finish before accessing the selection
To place the cursor at the end, the selection start needs to be placed at the end
In order to scroll to the end of the input field, the scrollLeft needs to match the scrollWidth
/**
* Upon focus, set the cursor to the end of the text input
* #param {HTMLInputElement} inputEl - An HTML <input> element
*/
