yes. The storage inside the optionset is column-based (which is rather
unavoidable, technically). So the typical pattern in js is:
col_a = getList ("set.col_a");
col_b = getList ("set.col_b");
col_c = getList ("set.col_c");
for (var i = 0; i < col_a.length; ++i) {
echo ("coolfun (", col_a[i] + ", " + col_b[i] + "," + col_c[i] + ")\n");
}

Well, it should be quite possible to create a JS function that converts from
column-based to row-based representation, given a list of column-names of
interested (which may of not be all columns in the set!). I'll leave that as
an exercise to the reader ;-).
