关于jQuery的Autocomplete插件的远程url取json数据的问题

$("#autocomplete").autocomplete("data.aspx", {
                    minChars: 0, 
                    max:15, 
                    width: 200,
                    scroll: false,
                    scrollHeight: 500,
              //需要把data转换成json数据格式
              parse: function(data) {
            return $.map(eval(data), function(row) {
                return {
                    data: row,
                    value: row.name,
                    result: row.name + " <" + row.to + ">"
                }
            });
        },
            formatItem: function(data, i, total) { 
                   return "<div style='float:left'>"+data.name+data.to+"</div>"
             },
             formatMatch: function(data, i, total) {
                        return data.name; 
                    },
             formatResult: function(data, value) { 
                        return data.name;
                    }
                }).result(function(event, data, formatted) {
                        $("#twoColum_abbr").val(data.to);
                    });
