Fill Select Automatically via If and Else with Jquery

Question

I am in need of a help. I have a form that captures address information through the zip code.

I need a Jquery function that will select a field in a select depending on the automatically filled value in the input with id estado. See how I tried but it doesn’t work:

$("#estado").val(dados.uf); // preenche o input estado automaticamente (funciona)
var estado = this.val(dados.uf); // aqui quero pegar o valor preenchido para selecionar automaticamente o select com id `selecione-estado`
if(estado == 'SP') {
    $("#selecione-estado option[data-sigla='SP']").prop("selected", true);
}
else if(estado == 'GO') {
    $("#selecione-estado option[data-sigla='GO']").prop("selected", true);
}

My selectis like this:

<select name="zone_id" id="selecione-estado" class="form-control" data-value="" data-cep="uf">
    <option value="" data-sigla=''> --- Selecione --- </option>
    <option value="440" data-sigla='AC'>Acre</option>
    <option value="441" data-sigla='AL'>Alagoas</option>
    <option value="442" data-sigla='AP'>Amapá</option>
    <option value="443" data-sigla='AM'>Amazonas</option>

Answer 1

do as follows:

var data = { uf: 'SP' };
var estado = $("#estado");
var select = $("#selecione-estado");
var option = $("option[data-sigla='" + data.uf + "']");
estado.val(data.uf);
select.val(option.val());

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<input id="estado" type="text" />
<select name="zone_id" id="selecione-estado" class="form-control" data-value="" data-cep="uf">
