Help with Javascript filter

Question

I have the following Javascript code:

JSON

var json = {

       "hotelPesquisa":[
          {
             "dtEntrada":"20170510",

             },
             "quarto":[

                }
             ]
          }
       ]
    };

Function

function filtro(min, max){
    var pesquisa = {
      min: min,
      max: max
    };
    var filtrados = json.hotelPesquisa.filter(function(hotel) {
        hotel.quarto[0].quartoUh = hotel.quarto[0].quartoUh.filter(function(quarto) {
            return quarto.tarifa.vlDiariaTotal  dados.min;
        });
        return hotel.quarto[0].quartoUh.length > 0;
    });
    console.log(filtrados);
}

I use Jquery UI the slider range that the code and:

$("#price-range").slider({
    range: true,
    min: 0,
    max: 1000,
    values: [ 0, 1000 ],
    slide: function( event, ui ) {
        tjq(".min-price-label").html(ui.values[ 0 ]);
        tjq(".max-price-label").html(ui.values[ 1 ]);
        filtro(ui.values[ 0 ], ui.values[ 1 ]);
    }
});

When I drag the slider it calls the filter function by passing the min and max parameters in order to filter the json with the minimum and maximum values of the slider. at first it even filters but after I drag the slider several times it returns empty:

[]

Does anyone know how I can fix this?

Example - Jsfiddle
The answers appears on the console.

Answer 1

The problem is that the array value was being overwritten in hotel.quarto[0].quartoUh = hotel.quarto[0].quartoUh.filter(....

Using

var filtrados = json.hotelPesquisa.filter(function(hotel) {
    var quartos = hotel.quarto[0].quartoUh.filter(function(quarto) {
        return quarto.tarifa.vlDiariaTotal < pesquisa.max && quarto.tarifa.vlDiariaTotal > pesquisa.min;
    });
    return quartos.length > 0;
});

already works well (https://jsfiddle.net/xrkuoqhq/4/). But to keep the part that filters rooms there are also different alternatives, one of them can be create clones like this: https://jsfiddle.net/xrkuoqhq/5/
