Feedback on http://docs.angularjs.org/#!/api/angular.Array.filter

Hi there, 

I read http://docs.angularjs.org/#!/api/angular.Array.filter and wanted to ask .... 

I have an JSON array:

phones = [{"name": "Nexus S",

                  "snippet": "Fast just got faster with Nexus S.","specs":[{"camera": "15px",

                  "FFC": "No"}]},

                 {"name": "Motorola XOOM with Wi-Fi",

                  "snippet": "The Next, Next Generation tablet.","specs":[{"camera": "11px",

                  "FFC": "No"}]},

                 {"name": "MOTOROLA XOOM",

                  "snippet": "The Next, Next Generation tablet.","specs":[{"camera": "15px",

                  "FFC": "No"}]},

           {"name": "MOTOROLA XOOM",

                  "snippet": "The Next, Next Generation tablet.","specs":[{"camera": "15px",

                  "FFC": "No"}]}];

Presently I am able to filter phones on basis of name, snippet and specs, however I am not able to search on basis of camera, can anyone explain ho to do that.

Regards

Use function as filter argument:

angular.Array.filter(phones, function(p) {

return p.specs[0].camera == '15px';

});

angular.Array.filter(phones, function(p) { for (var i = 0; i < p.specs.length; i++) { if (p.specs[i].camera == '15px') return true; } return false; });

Thanks for your replay, however want to know where should I use this
function, whether in the controller or in the view.

You need to unit test this, so the answer is: in controller.

You can't define function in template..
