Eric,
It appears my ev_command_enter is NOT being triggered by pressing the Enter
key while in the text field. I have even placed a debugging counter, T, in
ev_command_enter, but it is not being incremented.
Could you or others look at the excerpt of code below, please? I have
patterned it after both Eric's demogl1.ijs and Bob's vlitejwiki.ijs, but
cannot seem to get over this bump in the road.
coclass'tgsj'
coinsert'jhs'
HBS=: 0 : 0
'<h2>Type in a turtle command</h2>'
'command' jhtext 'fd 10';50
'<canvas width="600" height="600" id="glcanvas"></canvas>'
)
jev_get=: create
create=: 3 : 0
'tgsj'jhr''
T=: 20
initTurtles 1
)
ev_command_enter=: 3 : 0
T=:T+1
s=: getv 'command'
". s
)
JS=: 0 : 0 NB. javascript
function ev_body_load(){init();} // must use JHS framework load handler
function ev_command_enter(){jsubmit();}
)
Thanks,
