Jquery UI自动完成的限制结果

Question

I wanted to ask, how can I limit results of search. This is piece of code, responsible for quering. I want to have only five autocomplete items.

Source:

 function( request, response ) {
        $.ajax({
            type : 'post',
            dataType: "json",
            data: {
                'person':request
            },

            url: 'PersonWatch/all',

            success: function(data) {
                response( $.map( data, function(item, i) {
                        return item.person
                }));
            }
        });
    }

Answer 1

Try

response($.map(data, function(item, i) {
             return i < 5 ? item.person : null
         })
        );
