[Biojava-dev] Javascript to wordwrap Fasta format

[Richard Holland]

You need to implement the 'onkeypress' function. This page has an example:

http://www.w3schools.com/jsref/jsref_onkeypress.asp

What you'd then do is append the key code to the end of the text (unless
Javascript already did it for you before passing the event - I'm not sure
if it does), then read the textarea content into a buffer, process it by
stripping and replacing newlines, then write it back out to the textarea,
like this:

cheers,
Richard
