Perhaps I was not making myself clear when I first posted this.
I know how to write the javascript, I know how to use struts
nested/logic tags. What I was looking for when I posted was
a solution whereby I could add new elements to a collection
in a form. Not update existing elements, thus increasing the
size of a collection based on properties from fields that
were added by client side scripting.
I've not been able to find a solution to this within the mailing
list. But I would like to the following.
I have a page with a collection of fields which are populated by
a form (via it's collection). I also have a button which would
allow the addition of a new row. (hopefully)
Name Descrip
[ xy ][ foo ]
[ ab ][ bar ]
Add
(1) I would like to have the add button add a new pair of text
input fields each time it is clicked. (2) I would like it if
clicking add did not make a request to the server this being the
case it suggests some kind of client side javascript adding the
new fields.
The problems of course with this are the following.
(1) client side code won't be able to utilise the struts tags
and as such I won't know what values to set the appropriate
input text element attributes to.
(2) It is highly likely that even if I solved problem (1) that
it would result in a IndexOutOfBounds exception, or just not
bother with the properties from the new fields.
Has anyone else solved this? Does struts have a mechanism for
dealing with this? I'm fully aware of nested/logic tags but
if they are the way I can't see how.
Suggestions would be appreciated, Thanks!
