Error while calculating fields in IOS safari

Question

I have a problem in the development of a small calculation system where the user needs to put a value in a field and the system brings the results according to a specific account.

In all windows browsers on computers and Android works properly, however for safari on IOS the fields simply do not work. Is there any systemic compatibility on this?

Follows code:

<script>
jQuery('.simularparcela')[0].type = 'button';
jQuery(".simularparcela").click(function() {
var valorparcelas = jQuery(".valorparcela");
var parcelas = jQuery('input[name="meses[]"]:checked');
var valorparcela = valorparcelas[0].value;
var parcela = parcelas[0].value;
      jQuery.ajax({
        dataType: 'json',
        type : "POST",
        url: "http://www.mettaconsultoria.com.br/calculoparcela.php",
        data: { valorparcela: valorparcela, parcela: parcela, id: 1 },
        complete: function(result) {
        console.log(result);
          var json = JSON.parse(result.responseText);
          switch(json.code) {
            case 200:
            parcela = parcela.replace(/(d)(?=(ddd)+(?!d))/g, "$1.");
            jQuery('input[name="vlrCredito"]')[0].value = json.Credito;
            jQuery('#td_parcela_consorcio')[0].innerHTML = parcela;
            jQuery('#td_parcela_financiamento')[0].innerHTML = parcela;
            jQuery('#td_credito_consorcio')[0].innerHTML = json.Credito;
            jQuery('#td_credito_financiamento')[0].innerHTML = json.Credito;
            jQuery('#td_vlr_parcela_consorcio')[0].innerHTML = valorparcela;
        jQuery('#td_vlr_parcela_financiamento')[0].innerHTML = json.parcelaFinanciamento;
            jQuery('#td_totais_consorcio')[0].innerHTML = json.ValorSaldoDevedor;
            jQuery('#td_totais_financiamento')[0].innerHTML = json.financiamento;
            jQuery('#td_economia')[0].innerHTML = json.diferenca;
            jQuery('#comple_tabela')[0].hidden = false;
            jQuery('#tabela')[0].hidden = false;
            jQuery('.oculta').css("display","");
            jQuery('.info').css('display','');
            break;
            case 400:
            $(".overlap").hide();
            alert(json.msg);
            break;
          }
        }
      });
