Hi



I'm making my first YUI application - an activity where the user drags

words into spaces in a body of text. This is to become a Moodle

question type.



So that I can assess how well the user has done, (and pass that

information to Moodle) when they click Submit, I need to work out which

words are in which spaces. I'm currently doing this by maintaining

a "Drop Record", but this is quite tedious. For example, if the user

drags a word off its target and drops it back in the "pool" of words I

have to update my drop record in the OnInvalidDrop method. I can't help

thinking I must be missing something.



Is there a simple way of asking a target what draggable items it has on

top of it? Or should I persevere with my drop record?

In the current release of DragDrop, there is no built-in way to do what you are

asking.



However, this example does basically what you are wanting:

Hi



I'm

making

my

first

YUI

application

-

an

activity

where

the

user

drags

words

into

spaces

in

a

body

of

text.

This

is

to

become

a

Moodle

question

type.



So

that

I

can

assess

how

well

the

user

has

done,

(and

pass

that

information

to

Moodle)

when

they

click

Submit,

I

need

to

work

out

which

words

are

in

which

spaces.

I'm

currently

doing

this

by

maintaining

a

"Drop

Record",

but

this

is

quite

tedious.

For

example,

if

the

user

drags

a

word

off

its

target

and

drops

it

back

in

the

"pool"

of

words

I

have

to

update

my

drop

record

in

the

OnInvalidDrop

method.

I

can't

help

thinking

I

must

be

missing

something.



Is

there

a

simple

way

of

asking

a

target

what

draggable

items

it

has

on

top

of

it?

Or

should

I

persevere

with

my

drop

record?

I didn't understand the code in that example very well, but your

message prompted me to look again and I can see now that, if I use a

similar approach, at the end of the user's interaction I can cycle

through the targets and, for those which have a "player" property, it

will point to the item on top of the target.



Thanks very much!
