What I would like is for the user to click on the text box.
If they then backspace, the text box clears. Otherwise any
other keystrokes are allowed to do normal editing (including
a subsequent use of the backspace).
thebox.value = "";
Here I simulate the user's previous search with defaults.
<INPUT type="text" name="/author" size="30" value="Mark Twain" maxlength="100" onClick="clearbox(this);">
As a first step, clearing the box is fine. I now want to fix
the function so that it watchs for keystrokes. If the first
keystroke is a backspace, test with
if (evt.keyCode == "8" )
and allow the line
to run, otherwise the keystroke is left in whatever buffer
it sits in, and the function just exits. As long as the user
doesn't click again (to avoid invoking the function) all
subsequent keystrokes (I hope) will just be editing.
My problem is that I don't know how to get the function to
read a single keystroke. I only know how to read keystrokes
with lines in the html like
onKeyPress = myFunction(event);
