    {
        \"updated_at\" : \"2012-01-01T06:25         


        

Answer 1

You can create a closure and pass it that way here is my example working

$.get('https://data.seattle.gov/resource/3k2p-39jp.json?$limit=10&$where=within_circle(incident_location, 47.594972, -122.331518, 1609.34)', 
  function(responce) {

    var filter = 'event_clearance_group', //sort by key group name
    data = responce; 

    var compare = function (filter) {
        return function (a,b) {
            var a = a[filter],
                b = b[filter];

            if (a < b) {
                return -1;
            } else if (a > b) {
                return 1;
            } else {
                return 0;
            }
        };
    };

    filter = compare(filter); //set filter

    console.log(data.sort(filter));
});
