It wasn't a performance issue at all - it was the fact that the data kept jumping about (as a result of the function(s) run on the key strokes) while the user was bashing away. So then you try introducing a delay so that it only happens when they pause for breath. But nothing you do can make it work seamlessly. I am afraid it is futile - text areas are not text editors. You really need a bespoke widget for the job. Of course I would be happy to see a jfiddle or something that did it well - but for us it was given up as a bad job. We changed the underlying database in the end.
But anyway....I am not the OP - and he may find all of this helps him with his problem.

I wouldn't think there be any noticeable difference in the typing performance, regardless of delete/insert, etc. I've never heard any complaints where this type of function has been implemented but I don't know your environment, of course.
Thanks,
Todd

In my case I tried all of that - but of course it just causes mayhem when the user is constantly editing, deleting, inserting, cutting, pasting. It caused more support calls than it was worth.

Have you tried adding a function on the onKeyUp event? Count the characters entered and insert a CR/LF after 50 characters are entered. Reset the counter to 0 after the new line has been added.
Thanks,

Subject: [WEB400] textarea that works for blocks of text and keeps length of each line
Have a cgi web screen with various input fields plus a textarea of 5 rows,
50 cols (columns).
The data field is 250 bytes.
Moving the 250a to the textarea should always have byte 51 starting 2nd line, 101 starting 3rd line, etc.
CSS controls colors, fonts, etc, but nothing specific to textarea.
Chrome and IE don't match, and both jumble the appearance where the textarea is always shorter than the 50 characters (in IE, and longer in
Chrome) and wraps to the next line.
<sample>
LINE1TENxxSECOND10xxTHIRD10xxx
FOURTH10xxFIFTH10xxxLINE2TENxx
SECONDTEN...
There is plenty of room for the whole 50 bytes to fit within page.
<td><textarea name="LONG" rows="5" cols="50"
wrap="soft"><data></textarea></td>
Many hours of google, w3schools,stackflow, etc and trying lots of stuff has not improved the issue.
I have put textarea in it's own table, but no difference. I am assuming it's width affected by other input type="text" on same panel.
Users really want the ability to paste in up to 250 bytes and then edit it into 5 lines of 50 (it's a description that comes from other sources).
Later printed on form and the alignment in the textarea has to match print..
This to me seems a standard data entry issue for web applications.
Is "textarea" just unsuitable for this kind of entry? It worked better in older browsers.
Has anyone found a definition that works in the current web world (this app is for customers and they have various browsers. App's been up for 16 years.
