Array filtering with multiple(or not) items

Question

I'm trying do a array filtering with multiples values, when i select the first filter(ALAMEDA CLUBE RESIDENCIAL(BEERSERV-01, BEERSERV-02) passing through that select the machine value(BEERSERV-01,BEERSERV-02) i receive in my filtered array the product linked with BEERSERV-01, and linked with BEERSERV-02. But if i add the another value in filter(PARQUE ECOVILLE(BEERSERV-03)) my array will be null(because when pass all theses values in filtering, will be nufied because isn't tested one by one. How i can fix that?

 public async gerarListaPDV(){
    let filtered = []
    this.filterarr = []
    console.log(this.filterarr.length)
    for(var x in this.pdvs_selecionados){
      for(var y in this.pdvs_selecionados[x].equipamentos){
        this.filterarr.push(this.pdvs_selecionados[x].equipamentos[y].nome_equipamento)
      }
    }
   
    this.lista_vendas_filtrada.filter((obj)=>{
           if(this.filterarr.includes(obj.equipamento)){
             console.log(this.filterarr)
             filtered.push(obj)
           }
    })
    this.exibir_por_pdv = filtered

    console.log(this.filterarr)
    if(this.filterarr.length >= 1){
      this.lista_vendas_filtrada = this.exibir_por_pdv 
    }
    else{
      this.lista_vendas_filtrada = this.lista_vendas_constante
    }
    this.carregarRelatorioTotal(true)
  
  }

Answer 1

your problem statement is hard to understand. I don't know what your issue is, but based on your code , there's an issue:

you're calling filter on this.lista_vendas_filtrada , but you're not returning anything in the callback. Please take a look at what filter method does - link

filter callback should return true if you want to keep the value in the new array that it returns, or false if you want to remove it from the new array it returns . filter does not modify the array it's called on.

Hope this helps. If you need more concrete answer, please edit your question to be minimal reproduceable example , write code in English, and format your question so it's not all in one unformatted paragraph.
