Hi All,
I have jsp code below try to implement dynamic dropdown list
I utilize javascript code Dynamic Option List from
http://www.mattkruse.com/javascript/
I want 4 line hard code below (from that jsp code)
listB.addOptions("1","bpp2","7","bpp3","8");
listB.addOptions("2","bdl1","4","bdl3","5");
listB.setDefaultOption("1","7");
listB.setDefaultOption("2","4");
to be replace with dynamic value extract from:
<html:optionsCollection property="locations" value="locationId"
label="locationName" />
become something like below
listB.addOptions( location[1].locationId, machine[1].machineName,
machine[1].machineId, machine[2].machineName, machine[2].machineId, ...,
machine[N].machineName, machine[N].machineId );
listB.addOptions( location[2].locationId, machine[1].machineName,
machine[1].machineId, machine[2].machineName, machine[2].machineId, ...,
machine[N].machineName, machine[N].machineId );
...
listB.addOptions( location[M].locationId, machine[1].machineName,
machine[1].machineId, machine[2].machineName, machine[2].machineId, ...,
machine[N].machineName, machine[N].machineId );
listB.setDefaultOption( location[1].locationId, machine[1].machineId );
listB.setDefaultOption( location[2].locationId, machine[1].machineId );
...
listB.setDefaultOption( location[M].locationId, machine[1].machineId );
THE PROBLEM is:
All properties I need, inside
<html:optionsCollection property="locations" value="locationId"
label="locationName" />
But I don't know how to transfer Location property (locationId) --as Object
array at Collection locations-- and Machine properties (machineId,
machineName) --as Object array on each Location-- into dynamic code above to
replace 4 line hardcode above.
Anyone expert out there can help?
Really appreciate your help.
TIA
-GI.
