Is there any possibility
how to change HTML
load() function to load the contents of another HTML file on your server and place it anywhere you want on the current page without refreshing (so you can even replace the current HTML if you like).
However, I know you say you can't refresh the page, but, if the only reason is because you need to keep the text in the textbox, you could use a form to
POST that text to another
.jsp page (or even the same
.jsp page, depending on how you go about it) where it will be available to you to use at your own discretion (to put it in another textbox, for example).
