[Webwork-user] Form - appending formnames based on row-number

[<rr...@ne...>]

To Webwork-users.

We have a form with a number of data. We save changed whenever the user
changes the data in a form-field (onChange event)
We need to make some calculations based on other values on the same row. =
In
order to handle this this want to append the row number on each field-nam=
e.
Example:
Item   Actual count   Min. count   Wanted count   Ordercount
   1              5            5             10            5
   5             10            5             10            0
   9              6            5             10            0
  15             12            5             10            0
Each formfield is named based on their column name eg:
itemId currCount      minValue     wantedValue    orderCount
There exist getxxx for each column. There exist and iterator to traverse
through the list of items.

Changing the field for item 9, min. count to 7 should change ordercount t=
o
4.
We need in the client javascript to be able to get each field and its val=
ue.

Furthermore we would like the user to be able to press key-down/up and ju=
mp
from field to field. (future option)

So from my point of view we have two options.
One is naming each formfield with the item-id. So the formfieldnames woul=
d
be
itemId1  currCount1   minValue1   wantedValue1  orderCount1
itemId5  currCount5   minValue5   wantedValue5  orderCount5
itemId9  currCount9   minValue9   wantedValue9  orderCount9
itemId15 currCount15  minValue15  wantedValue15 orderCount15
Calling the onChange script should then send the itemId as an parameter.
How could we name the field based on the itemId ? And how should this loo=
k
like for webwork ?

The second option (and our prefered) - using a rowcounter eg:
itemId1  currCount1   minValue1   wantedValue1  orderCount1
itemId2  currCount2   minValue2   wantedValue2  orderCount2
itemId3  currCount3   minValue3   wantedValue3  orderCount3
itemId4  currCount4   minValue4   wantedValue4  orderCount4
This will help us move up and down, and would be easier when we are not
using a simple primary-key like itemId.
How can we setup WebWork to handle a rowcounter in an iterator, and how c=
an
we append it to the name-field ??

And inputs would be really appreciated
thank in advance
