Hola

A ver si te sirve esto:
Código javascript
:
Ver original<html>
<head>
<script type="text/javascript">
function copiar(frm) {
frm.oculto.value = frm.t1.value+' '+frm.t2.value+' '+frm.t3.value;
}
</script>
</head>
<body>
<form>
<input type="text" name="t1" onkeyup="copiar(this.form)" />
<input type="text" name="t2" onkeyup="copiar(this.form)" />
<input type="text" name="t3" onkeyup="copiar(this.form)" />
<input type="hidden" name="oculto" />
</form>
</body>
</html>
Saludos,
