Filtering data source dynamically

[Gabriel]

Instead of listing the filters in code like this:

dataSource.filter([    

{ field: "orderId", operator: "neq", value: 42 },    

{ field: "unitPrice", operator: "ge", value: 3.14 }

]);

I would like to add them from a JSON array. How would I go about this? When I try, all I get is one filter being appended to the query string not in the correct format, rather looking like this:

filter[filters][]

instead of:

filter[filters][0][field]

filter[filters][0][operator]

filter[filters][0][value]

Not sure about the JSON bit, but I had luck using a straight forward array.  Maybe you need to cycle thru the JSON  and build an array then set using that?

 var A = new Array();
 A.push({ field: "somefld", operator: "eq", value: "Foo" });
 A.push({ field: "somefld", operator: "eq", value: "Fee" });
 A.push({ field: "someotherfld", operator: "eq", value: "Fi" });
 dataSource.filter(A);

Thanks Andrew. I had my Javascript arrays screwed up.
Cheers.
