Hi Anthony,
In my case, the form is displaying question, image and 4 choices from a
database. Since the database has many other information like answers etc, i
decided to customize the form completely by handcoding the html. In between
the html, i am having statements like {{=db.quiz[1].Achoice}} to inject
data from the database.
Now, when the user enters a choice by selecting a radio button and submits
the form, I want to navigate the DOM. There is no statement like
form=SQLFORM(...) or form=FORM(....) etc in my controller. So how should i
now do the DOM parsing ?
Regards,
Bhaskar
