JS: why applet reloads after input value?

i don't catch what's happening to my JS code in this file...

i'm trying to introduce a certain value from the textarea into a parameter called e, inside the applet.

in essence, it goes like this:

<form name="Entrada" action="" onsubmit="NouValor(Entrada.inputField.value);

Entrada.inputField.value='';">

</form>

function NouValor(Value) {

var strInput = Math.round(Value * 2000 / document.ggbApplet.getValue("nt"));

document.ggbApplet.evalCommand('e = ' + strInput);

return false;

}

</script>

after introducing a value into the textarea and pressing return, the applet reloads!!

Hi,

pressing enter submits the form => sends the data via HTTP GET request. Try

onsubmit="NouValor(Entrada.inputField.value);Entrada.inputField.value='';return false;">

to prevent this.

(sometimes you get a great satisfaction when realising how reasonable a computer behaviour can be)
