Send selected value of the option by parameter

Navigation

I'm developing a Java application where I get the data from the database and present it to a <select><option> but I do not know how to get the value selected and send per parameter.

  

JSP 

<c:choose>
<c:when test="${!empty param.descricao}">
<c:forEach items="${requestScope.produtos}" var="registro"> 
 <div class="col-sm-6 col-md-6"> 
  <h3>${registro.descricao}</h3>
  <p>${registro.codigo}</p>
  <div class="linha_compra"></div><br/><br/> 
  <div class="col-sm-6 col-md-6">
  <p>${registro.valor}</p> 

  <select id="parcelas">
   <option value="1"> ${registro.prod_parc1}</option>
   <option value="2">${registro.prod_parc2}</option>
   <option value="3">${registro.prod_parc3}</option>
   <option value="4">${registro.prod_parc4}</option>
   <option value="5">${registro.prod_parc5}</option>
   <option value="6">${registro.prod_parc6}</option>
   <option value="7">${registro.prod_parc7}</option>
   <option value="8">${registro.prod_parc8}</option>
   <option value="9">${registro.prod_parc9}</option>
   <option value="10">${registro.prod_parc10}</option>
  </select><br/><br/>  
  <div class="col-sm-6 col-md-6">
   <button type="button" onclick="" class="botao_comprar"><a href="http://localhost:8080/EccomerceJSP2/Carrinho?descricao=${registro.descricao}&valor=${registro.valor}&parcela=">COMPRAR</a></button> 
  </div>
 </div>
</c:foreach>

Good morning friend, before we help you, let's consider some changes.

You are using a link to make a request, in case: 

<a href="http://localhost:8080/EccomerceJSP2/Carrinho?descricao=${registro.descricao}&valor=${registro.valor}&parcela=">COMPRAR</a>
