This is what i need Tony, I want to be able to count elements from the
database and use what i get from the database in my array without having to
explicitly hard code the number. If i have 5 elements i want to be able
show those 5 elements and if they are 8 i want to be able to use the 8
element, whatever number of elements is found in the table should be able
to automatically be accommodated in the JavaScript array for the slide show.
What i got from Stack Overflow works, I am able to extract elements
individually as requested but the problem comes when i have to use them in
my JavaScript array. I have to be specific and individually display them in
the array. Cant i just put a reference like this which holds any number of
elements and have those elements offloaded into the array as below:
*FUNCTION:*
*def form1Details(): form=db.compForm(request.args(0))
forms=db(db.compFormPages.formName==form.id).select(db.compFormPages.ALL)
return dict(forms=forms)*
*VIEW:*
*{{for pic in forms:}}{{pass}} <script> images =
["{{=URL('download', args=pic.formImage)}}"];
descriptions=['{{=pic1.formTitle}}'];*
and have this code show all the pics and their descriptions and not do like
below where i have to be specific with the number of elements i want in an
array!!
*images = ["{{=URL('download', args=pic1.formImage)}}", "{{=URL('download',
args=pic2.formImage)}}", "{{=URL('download',
args=pic3.formImage)}}"];descriptions=['{{=pic1.formTitle}}',
'{{=pic2.formTitle}}', '{{=pic3.formTitle}}'];*I do not not know if i give
sense but i hope i do.
