Jquery Ajax Response

This is my code

controller =  $("#src_controller").val();
source_id =  '#' + $("#src_filter_tags").val();
$.ajax({
    type: "GET",
    data:"id=" + $(this).data('tagId'),
    dataType: "json",
    url: "index.php?controller=" + controller + "&action=FindByTag",
    success: function(response){
        var resultArray = [];
        $.each(response, function(k, v) {
            resultArray.push(v.*);
        });
        console.log('#' + $("#src_filter_tags").val());
        $(source_id).val(resultArray);
        return 1;
    },error: function() {
        console.log("error");
    }
});

What I want is on the line     resultArray.push (v. *); the asterisk is the name of the field that I bring from the database.

I want it to change dynamically, that is, assign a variable to that asterisk so that with each iteration of each I take a different variable.

Another solution would be to get the first value of what I get for JSON.

The problem is that depending on which table in my database asks the fields ids are different.

For example

Table1 = > table_id1 Table2 = > table_id2

So what I want to do is variable = table_id1 or table_id2 resultArray.push (v.variable);

I've managed to do it like this:

$.each(response, function(k, v) {
    $.each(v, function( k, v ) {
        resultArray.push(v);
        return false;
    });
});

I want to do this in a cleaner way
