Hey Raul,
I am certainly in no position to give any advice on web programming, but in my
stumbling about I found the most useful area on investigation for JHS was to
look at the demo's. Specifically demo1 and the link to demo1.ijs on the demo
page show how jsubmit is used (it looks like it is one way for javascript
functions and j verbs to communicate, as long as naming conventions are
followed) The core javascript function are kept in JS_jhs_ and I was able to
find ev_log_enter in the jijx.ijs script where JS_jhs_ is defined.
Hope this helps.
Cheers, bob
