How to assign a value to a variable in struts from JavaScript?

Question

Good morning, I have been working on this problem for a while and I didn't found a solution in google for it.

There is a way to assign a value to a variable in Struts from JavaScript? I'm new working with Struts so is costing me a little..

This is a part of the code I'm using:

In some part of the code first i create this little guy:

<input type="hidden" name="identificadorProspecto" id="identificadorProspecto" value="-1">

After making some connections to data base I update this value

<script language="JavaScript" type="text/javascript" >
    var idContainer = document.getElementById('identificadorProspecto');
    alert("idContainer.value: "+contenedorIdentificacion.value);
</script>

<s:url id="car_suc_xx223" action="listar_sucursales.action" >
    <s:param name="cod_prospecto" value="%{identificadorProspecto}" />
</s:url>

When i get the alert message, I don't receive the same value that I get in the value="%{identificadorProspecto}" (this one has some random value)

You can do it by using a property tag. For example

<script type="text/javascript">
    var idContainer = document.getElementById('identificadorProspecto');
    idContainer.value = '<s:property value="%{identificadorProspecto}">'; 
    alert("idContainer.value: "+idContainer.value);
</script>
