Banging my head against Spry!

Question

I'm am creating a job search filter page:
Loading the XML with all the jobs, then from a selection of
options filter them down.
OK, done that. I am using the 'or' filtermode in the
SpryDataExtensions.js
You can filter by job and location.
So you can select to filter by job types:
'general office' or 'sales' or 'accounts'
then you can look for jobs at locations
'thame' or 'aylesbury' or 'benson'
so it brings back anything in the xml with 'general office'
or 'sales' or 'accounts' or 'thame' or 'aylesbury' or 'benson'
What I need it to do is
'general office' or 'sales' or 'accounts' AND 'thame' or
'aylesbury' or 'benson'
so a 'sales' job in 'oxford' will not appear but it only
returns job types I have selected in the towns I have selected.
Hope this is clear???
Have a look and play - you should see what I mean

My question is can it be done in single page?
If so, fantastic but how?

From a grouping perspective, I think that you're asking for
something like this:
('general office' or 'sales' or 'accounts') AND ('thame' or
'aylesbury' or 'benson')

I suspect that it can, but I think that you might need to
create a "master" filter that pulls in all of the checked checkbox
items for the job category and all of the location check boxes.
pseudo code:
function jobTypeAndCityFilter(ds, row, index){
var selectedJobTypes = {};
// cycle through all of the job type checkboxes
var atLeastOneJobType = false;
// Assumes an id of JobTypes on the table with the job type
checkboxes
// and that the job type checkboxes have a value set that
matches the job category
// leave the value empty for the show all and remove all
var jobTypeCBs = Spry.$$("#JobTypes
input[type=checkbox][value~='']");
for(var i=0; i< jobTypeCBs.length; i++){
if(jobTypeCBs
.checked){
selectedJobTypes[jobTypeCBs.value] = true;
// assumes that you add a value to each checkbox that matches
the job type to filter on
atLeastOneJobType = true;
var categoryFound = false;
// if no job types found, any category will do
// or if current row category is one of the checked job types
if(!atLeastOneJobType || row.Category in selectedJobTypes){
categoryFound = true;
var atLeastOneCity = false;
var selectedLocations = {};
// Assumes an id of Locations on the table with the location
checkboxes
// and that the location checkboxes have a value set that
matches the location in the dataset
// leave the value empty for the show all and remove all
var LocationsCBs= Spry.$$("#Locations
input[type=checkbox][value~='']");
// cycle through all of the city checkboxes
for(var i=0; i< LocationsCBs.length; i++){
if(LocationsCBs
.checked){
selectedLocations[LocationsCBs.value] = true;
atLeastOneCity = true;
var cityFound = false;
// if no city filters found, any location will do
// or if current row category is one of the checked job types
if(!atLeastOneCity || row.Location in selectedLocations){
cityFound = true;
// If we have found an appropriate category and an
appropriate city, return the row.
if(categoryFound && cityFound ){
return row;
} // end function
// Called onclick of each of the job type and locations:
function HandleJobCityFilterChange(){
// remove in case filter is already present to prevent
// multiple applications of the same filter, then readd it
dsDonuts.removeFilter(jobTypeAndCityFilter);
dsDonuts.addFilter(jobTypeAndCityFilter, true);
// Example checkbox:
<input name="GeneralOfficeCB" type="checkbox"
value="General Office" onclick="HandleJobCityFilterChange();" />
I think you'll need to call the HandleJobCityFilterChange
function at the end of your set/remove all options. The above
method simply polls all of the job categoy checkboxes and the
location checkboxesAnyway, this was all hacked together real
quickly as I've not done much with datasets, but in a very very
quick test using Thame and Sales, it appeared to work correctly to
show only one job: reference 10762
Hope that helps you on your way, but from here, I'm not sure
I'll be able to help much.
