Parse Multiple checkbox value Jquery ajax

Parse Multiple checkbox value Jquery ajax

I need to parse with ajax to php file the following form. I can't use use
serialize().
< input type="checkbox" name="Filter[0]" value="Train" id="Filter">
< input type="checkbox" name="Filter[1]" value="Airplane" id="Filter1">
I was thinking
var Filter = $('#Filter').val();
.....
data: {..., ..., Filter:Filter}
it doesn't work. Any Idea?
