Thank you for this great snippet! I had some trouble with appended input elements that could contain a value, since. This snippet saved me from a lot of extra work. Has anyone gotten that to work? Those having trouble with this code might check what other events are bubbling through the DOM. For example, if you trying to fire the code in the example from an up-arrow keypress, the code will run properly [and move the cursor to the end of the input field], but then the up arrow keypress will bubble up to the browser [which directs it to move the cursor to the start of the input field].

Change: target. Author Commented: It doesn't work, the cursor is still at the most top-left position.While working on another project, I needed a way to insert some text at the current cursor position in a textarea to auto-complete what user is typing.

It turns out this simple task is almost impossible to achieve if you want the browser to not choke on a big text inside a textarea. Of course, as I stumbled onto this problem, I reached out to a trusty search engine pointing me towards ever-prevailing StackOverflow and a couple of answers there 12.

While this does work, I became very suspicious that it might not perform well with large documents. A quick check in JSBin revealed that on a decent-sized document Firefox, IE and Edge spend around 10msms on my beefy desktop computer and Chrome is spending more than 45ms.

In Chrome the delay is noticeable even without other work. If we try to push the size of the data in the textarea even further, things become truly grim. The regular input, however, stays very responsive. At this point, I remembered about document. Performance is on par with regular text input by the user, and the code is extremely simple:. Firefox, unfortunately, does not support this behavior. After some significant digging through MDN I stumbled upon a non-standard setRangeText that did not have any documentation, but did exactly what I wanted, except for updating cursor position and sending input event, but both are super easy to fix.

So together we now have:. It looks like we might be done, but if you pay attention, there is still on browser missing — IE And there is a good reason for it. Probably a better title of this section is "a story on how not to deal with backward compatibility. What it means in practice is that the code shown at the end of the previous section does not work in version 11, and neither does any method, except for the re-setting the value.

When I was almost ready to give, I noticed that the following code did add stuff to the textarea when it was empty:. The code did error out if I tried to insert on pretty much any other position than 0but it got me curious. Armed with developer tools and a bunch of console log statements I was able to figure out that unlike every other browser, IE11 treats the content of a textarea as a text node.

With regular interaction, you either have none if the textarea is empty, or one text node. What is interesting though, is that the browser allows multiple text nodes inside.

My next evil plan was to use the splitText method of the Text node and then insert a new text node manually at the right position. Unfortunately, this resulted in all kind of weird behavior where IE would just insert things at random places. Since Range seemed to have almost worked, I decided to get back to that idea, but instead of setting up Range on the textarea itself, I set it up on the child nodes. The calculations to figure out starting and ending node is a bit hairy:.

The result is worth the effort though. Insertions are again on par with regular text input. One unfortunate thing is that it does not work for regular text inputs only textareasbut I would not expect anyone to put a few hundred KB text into an input, so it seems ok. As I mentioned at the start of the article, I have gathered all of the code from this article, sprinkled some extra code for resilience in case any of the browsers decide to drop support for undocumented features the code relies on and published it as an npm package.
