Is it possible to filter a Slickgrid without using the DataView?
In case it isn't possible, how should the data array be structured in order to display correctly?
I don't have a working example atm. Thanks
Later edit:
After doing some more homework, a filterable datagrid is all about getting matching indexes in a nested array... to get a live sorted result-set that gets updated with grid.setData(filterData);grid render; one should do the following
function intersect(a, b) // find an intersection of 2 arrays (google result on SO
{
var ai=0, bi=0;
var a = a.sort();
var b = b.sort();
var result = new Array();
while( ai < a.length && bi < b.length )
{
if (a[ai] < b[bi] ){ ai++; }
else if (a[ai] > b[bi] ){ bi++; }
else /* they're equal */
{
result.push(a[ai]);
ai++;
bi++;
}
}
return result;
}
// given results sets are arrays of indexes matching search criteria
a = [1,2,3,4];
b = [2,3,4,5];
c = [3,4,5,6];
d = [4,5,6,7];
// should reunite in a nested array
array = [a,b,c,d];
// check intersections for each array[k] and array[k+1]
k = array[0];
for (var i = 0; i<array.length-1; i++){
k = intersect(k,array[i+1]);
}
console.log(k) // returns 4
// k array is the index array that
// is used to build filterData[i] = data[j]
// depends if id is stored in data or in case
// of a database, it is stored in data
// tested in firebug
// thanks

Filter the underlying data array and call grid.setData(filteredData)
.
