Posted by: admin November 7, Leave a comment. I believe I would have to store in a variable the current cursor position when they are leaving focus of the div, and then re-set this when they have focus inside again, but I have not been able to put together, or find a working code sample yet.

Perhaps only for textarea How to move cursor to end of contenteditable entity.

Test your JavaScript, CSS, HTML or CoffeeScript online with JSFiddle code editor.

This is compatible with the standards-based browsers, but will probably fail in IE. This works perfectly unless you want the selection to be restored when the user clicks the div aswell which is a bit unintuitative as normally you expect the cursor to go where you click but code included for completeness.

To achieve this the onclick and onmousedown events are canceled by the function cancelEvent which is a cross browser function to cancel the event. This allows click events to be cancelled only if the div is not in focus otherwise you would not be able to change the selection at all. If you wish to the selection to be change when the div is focused by a click, and not restore the selection onclick and only when focus is given to the element programtically using document.

The onblur event and the onDivBlur and cancelEvent functions can also safely be removed in these circumstances. This code should work if dropped directly into the body of an html page if you want to test it quickly:. Browsers it works in are IE 5. Note that selections may be made backwards in browsers so that the focus node is at the start of the selection and hitting the right or left cursor key will move the caret to a position relative to the start of the selection.

I had a related situation, where I specifically needed to set the cursor position to the END of a contenteditable div. In the end, I came up with this simple jQuery function to set the carat position to the end of a contenteditable div:.

The theory is simple: append a span to the end of the editable, select it, and then remove the span — leaving us with a cursor at the end of the div. You could adapt this solution to insert the span wherever you want, thus putting the cursor at a specific spot.

I'm finding tons of good, crossbrowser anwers on how to SET the cursor or caret index position in a contentEditable element, but none on how to GET or find its index So, when the user is typing text, I can at any point know its cursor's index within the contentEditable element.

If you need a more general approach that will work content with nested elements, try this answer:. Kinda late to the party, but in case anyone else is struggling. None of the Google searches I've found for the past two days have come up with anything that works, but I came up with a concise and elegant solution that will always work no matter how many nested tags you have:. It selects all the way back to the beginning of the paragraph and then counts the length of the string to get the current position and then undoes the selection to return the cursor to the current position.

If you want to do this for an entire document more than one paragraphthen change paragraphboundary to documentboundary or whatever granularity for your case. Check out the API for more details. Note: the range object its self can be stored in a variable, and can be re-selected at any time unless the contents of the contenteditable div change. As this took me forever to figure out using the new window.

Note that MDN suggests there is wider support for window. Here is a jsfiddle that fires on keyup. Note however, that rapid directional key presses, as well as rapid deletion seems to be skip events.

A straight forward way, that iterates through all the chidren of the contenteditable div until it hits the endContainer.

Then I add the end container offset and we have the character index. Should work with any number of nestings.I am a bit confused. Other elements p, div seem to be OK! I only need solution for compliant browsers. What do you mean the index? Index, by my definition is, the numbers indicate the position order of elements within a container. In this code, the id blinking represents the node where the caret is.

What I am trying to archive is, when I open a working document, I want the caret to be exact position when I left off.

To do so I need to store the words offset and the node which contain the caret, but the node returned by selection. Therefore, we need to get the index value of the node. There is a stack overflow question which was very easy to find via google addressing your issue.

Those codes on Stackoverflow basically get selection, and restore it as long as page is live. The tricky part is to get the node index, as you can see in function setCaretPos, there is node index utilizing. And I attained it by using jquery index function, as seen in alert function above. For this snippet work correctly, The html inside contenteditable needs to be controlled strictly. Hopefully, I can improve it to work with arbitrary html.

Actually it works because of the error in my console Uncaught TypeError: Cannot read property 'value' of undefined. The rerendering is never triggered so it's normal the caret does not jump, but it does not work actually because I need to update the state.

This prevents the caret from jumping. Polling innerHTML would not make much practical sense at all I think, it could be prohibitively expensive and for most cases you wouldn't want it. I think there's some experimentation going on with controlled content-editables, but uncontrolled is the only sane way for now AFAIK.

Ah, yes, my answer was wrong. The only idea I have now is to change shouldComponentUpdate like this:. Then the cursor does not jump when the user types, But it still jumps when the change comes from the script.

It would be interesting to know if this could be done in a more controlled way. You need to get the cursor position before setting and restore it after. The cursor does not jump if you do not touch the nodes of the selection I think, works for me. I know this is an old closed issue but I wanted to chime in on a simple solution for people that run into it.

This only happens when you mutate the value so the DOM representation is different to a state value that's being set. Simple solution - add a ref, mutate the ref's value to the manipulated one, then update the state.

It's not quite as clean but it solves all the problems. For anyone else who, like me, ends up looking at this ticket because they think they need to roll their own contentEditable for a fancier text input: make sure to check out Facebook's DraftJS and the 3rd-party DraftJS Plugins project --might save you a lot of time.

This works perfectly unless you want the selection to be restored when the user clicks the div aswell which is a bit unintuitative as normally you expect the cursor to go where you click but code included for completeness. To achieve this the onclick and onmousedown events are canceled by the function cancelEvent which is a cross browser function to cancel the event.

The cancelEvent function also runs the restoreSelection function because as the click event is cancelled the div doesn't receive focus and therefore nothing is selected at all unless this functions is run. The variable isInFocus stores whether it is in focus and is changed to "false" onblur and "true" onfocus. This allows click events to be cancelled only if the div is not in focus otherwise you would not be able to change the selection at all. If you wish to the selection to be change when the div is focused by a click, and not restore the selection onclick and only when focus is given to the element programtically using document.

I've written a cross-browser range and selection library called Rangy that incorporates an improved version of the code I posted below. You can use the selection save and restore module for this particular question, although I'd be tempted to use something like Nico Burns's answer if you're not doing anything else with selections in your project and don't need the bulk of a library.

I've created a demo of a script that does this. It works in everything I've tried it in so far except for a bug in Opera 9, which I haven't had time to look into yet. Browsers it works in are IE 5. Note that selections may be made backwards in browsers so that the focus node is at the start of the selection and hitting the right or left cursor key will move the caret to a position relative to the start of the selection.

I don't think it is possible to replicate this when restoring a selection, so the focus node is always at the end of the selection. I had a related situation, where I specifically needed to set the cursor position to the END of a contenteditable div.

I didn't want to use a full fledged library like Rangy, and many solutions were far too heavyweight.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I have contentEditable element can be p, div, I can normally achieve it with this piece of code:.

This works fine while the element contains just text. This is actually a more useful result than a character offset within the text of the whole document: the startOffset property of a DOM Range which is what window. However, if you really want a character offset, here's a function that will do it. This is a very old post, but still one of the first results searching on Google, so maybe still useful.

This works for me to get right position considering html tags and newlines as well tested on Firefox :.

Could you please try to fix it as I've tried it with no luck. I've changed your code to display caret position inline and also it would react to keyup event.

The code works well, but it returns wrong result when caret is at the start or the end of tag. Try it yourself, just click in contentEditable div and keep pressing right arrow key to move caret.
