Question

How do I convert the jquery code below to prototype?

<script> 
    $(document).ready (function() {
        $("#valor").keyup(function(){
            var resultVal = 0.0;
            var objRegExp = '\s+';
            $("#valor").each ( function() {
                resultVal += parseFloat ( $j(this).val().replace(/\s/g,'').replace(',','.'));
            });
            $("#total").val(resultVal);  
        });
    });
</script>

Thanks.

I don’t know, but pure JavaScript is always nice:

function doLoad() {
     var valor = document.getElementById("valor");
     valor.onkeyup = function() {
          var resultVal = 0.0;
          var objRegExp = '\s+';
          for(var i = 0; i < valor.childNodes.length; i++) {
               var n = valor.childNodes[i];
               if(n.nodeType === 1) resultVal += parseFloat(n.value.replace(/\s/g, '').replace(',', '.'));
          }
          document.getElementById("total").value = resultVal.toString();
     };
}

if(window.addEventListener)
     window.addEventListener("load", doLoad, false);
else
     window.attachEvent("onload", doLoad);
