JavaScript innerHTML Won't Update While Script is Running?
I am appending text to document.body.innerHTML, but it doesn't appear in the document until after my script terminates. The code works fine; the output is just not visible. [When I use Firebug, I can see the correct output every time it stops at a breakpoint.]
I am trying to simulate an old-style CGA environment: upper-case white text on a black background with 80 characters per line and 16 lines on the screen (you probably won't remember the TRS-80 unless you're over 30). This means I have to write four functions: inputChar, outputChar, inputLine, and outputLine. Not a big deal, but the user can't view the output until the script terminates. The trouble is that the script can't terminate until we go through the input, output, input, output many times - the ultimate catch-22.
While typing, I figured out that I can redesign the code to make everything trigger on the user's keypress, but that's a major logic rewrite. Can you think of any other way I can show the output immediately rather than after the script terminates?

what is triggering your script now? Just running at loading? Whatever scripts need to run at loading have to finish first.
You could try starting your script with a timer, leave it as is but not be triggered at loading, but I have a feeling the keyboard trigger will be much better.
