eliminar y añadir valor según radio pulsado

[Perr0]

hice unos cambios, la idea es que con cada clic, recorra el arreglo completo:

Código Javascript:

<script type="text/javascript">
var i
window.onload = function(){
    f = document.forms.item("formulario");
    for ( i = 0 ; i < f.length ; i++ ){
        if ( f.elements.item(i).type=="radio" ) f.elements.item(i).onclick = function(){recorrer();}
    }
}
 
function recorrer(){
    texto = document.getElementById("search_query_block")
    texto.value = ""
    sep = ""
    for ( i = 0 ; i < f.length ; i++ ){
        if ( f.elements.item(i).type=="radio" && f.elements.item(i).checked==true)
        {
            var nombre = f.elements.item(i).value
            texto.value = texto.value + sep + nombre
            if ( sep == "" ) sep = " ";
        }
    }
}
</script>
 
<div id="search_block_left" class="block exclusive">
    <form name="formulario" method="post" action="{$link->getPageLink('search', true)}" id="searchbox">
        <p class="block_content">
            <label for="search_query_block">{l s='Enter a product name or description.' mod='blocksearch'}</label>
            <input type="hidden" name="orderby" value="position" />
            <input type="hidden" name="controller" value="search" />
            <input type="hidden" name="orderway" value="desc" />
            
            <!-- Selectores Personal Shoppers -->

        </p>
    </form>
</div>
