Brian, I see you switched to trying ajax in your latest version. I can
take a look at it tomorrow. Here's the version from your previous
message. It correctly fires ev_command_enter on my chrome browser when
I hit enter. It also returns the result of the evaluation:
I suspect your ajax version had the same issue. You need to return a
valid HTTP response from the POST or ajax response. In this case, I am
calling create with the parameter evaluated from ev_command_enter. The
valid HTTP response is created and output using jhr
coclass'tgsj'
coinsert'jhs'
HBS=: 0 : 0
'<h2>Type in a turtle command</h2>'
'command' jhtext '1+1';20
'Result: <RESULT>'
'<canvas width="600" height="300" id="glcanvas"></canvas>'
)
jev_get=: create
create=: 3 : 0
'tgsj'jhr'RESULT';y
T=: 20
)
ev_command_enter=: 3 : 0
T=:T+1
s=: getv 'command'
ret=:". s
NB. return valid HTTP response
create ": ret
)
JS=: 0 : 0 NB. javascript
function ev_body_load(){} // must use JHS framework load handler
function ev_command_enter(){jsubmit();}
)
