Roll dice into a box

I need to take the data of an input and pass to a box! I have a Cod that takes the dice from a combo to play in a box!

Cod:

function move(Origem, Destino)
{
    var opt = document.createElement("option"); 

    for(i = 0; i < Origem.options.length; i++)
    {
        if (Origem.options[i].selected && Origem.options[i].value != "")
        {
            if(w_seq_qtde[Origem.options[i].value]==0)
                alert("sem periférico no estoque!");
            else
            {
                document.getElementById("cb_MenuDestino").options.add(opt);
                opt.text = Origem.options[i].text;
                opt.value = Origem.options[i].value;
                w_seq_qtde[Origem.options[i].value]--;
            }
        }
    }
}

input:

<input type="text" name="tx_MenuOrigem" value="">

button :

<input type="button" onClick="move(this.form.tx_MenuOrigem,this.form.cb_MenuDestino)" value="+++">

select:

<select multiple size="7" name="cb_MenuDestino" style="width:300"></select>

In this case when selecting the item in the combo and pressing on a button to add it plays in the box! But I want to take the dice in an input and play inside the box! If possible has to be more or less similar for better understanding?! Thanks to those who help!

function move(input, Destino)
{
 var opt = document.createElement("option"); 
 var valor = input.value;
 if(valor=="")
 return;

  if(valor==0)
  { 
    alert("sem periférico no estoque!"); 
   return;
  }            

  opt.text = valor ;
  opt.value = valor ;
  Destino.options.add(opt);

 }

  • I want to block if the data is the same as entered, as I do?

  • Can you explain how your answer solves the problem?

  • Function Jaexiste(Destination, value) { for(i = 0; i < Destination.options.length; i++) { if (Destination.options[i].value == value) Return true; } Return false; } &#Function moves(input, Destination) { var opt = Document.createelement("option"); var value = input.value; if(value==""|| Jaexiste(Destination,value)) Return; if(value==0) { Alert("without peripheral in stock!"); turn; } opt.text = value; opt.value = value ; Target.options.add(opt); }

Check if the value already exists

function JaExiste(Destino, valor)
{

for(i = 0; i < Destino.options.length; i++)
    {
        if (Destino.options[i].value == valor)
                   return true;
     }
return false;
}

Add value in select

function move(input, Destino)
{
//Obtém o valor digitado 
 var valor = input.value;

 //retorna se não houver valor ou se o valor já existir no destino

 if(valor==""|| JaExiste(Destino,valor)) return;

//Mensagem do explo caso o valor seja 0
  if(valor==0)
  { 
    alert("sem periférico no estoque!"); 
   return;
  }        
  var opt = document.createElement("option"); 
  opt.text = valor ;
  opt.value = valor ;
  Destino.options.add(opt);
 }
