Eric,
Yes, I changed the jev_get to `jev_get=: create` and then decommented
(they were commented in the previous version) the following two lines in
JS. Can you see what I can do now, please?
function ev_command_enter(){jdoajax(["command"],"");}
function ajax(ts) {jbyid("command").value=ts[0];}
*** event handler error
ev_command_enter 0
|syntax error: jev_tgsj_
| ev_command_enter 0
jdo jev_tgsj_ 0
jtype enter
jmid command
jsid
command fd 10
jdata
jwid
