<head>
<title>
Calculadora Ajax
</title>

<script src="jquery-1.2.3.min.js" type="text/javascript"> </script>
<script type="text/javascript">

function validar(formu)
{
numemp = parseInt(formu.numeroEmpleados.value, 10); //convierte en valores enteros los datos del formulario (base 10)
tc1 = parseInt(formu.TC1.value, 10);
cf = parseInt(formu.CF.value, 10);

if ( isNaN(numemp) && isNaN(tc1) ) { //valida que sean numeros
alert("Debe cumplimentar los dos campos con valores numericos.");
return false;

}
if ( numemp < 0 || tc1 < 0 ) { //valida que sean positivos
alert("Los valores numericos introducidos deben ser positivos.");
return false;
//ok, envio formulario
}

if (numemp >= 6 && numemp <=9 )
{ cf = tc1 * 0.007;
alert("Credito formativo = " + cf);
return true;
}
if (numemp > 10 && numemp < 49 )
{ cf = tc1 * 0.007 * 0.075;
alert("Credito formativo = " + cf);
return true;
}
if (numemp > 50 && numemp < 249 )
{ cf = tc1 * 0.007 * 0.060;
alert("Credito formativo = " + cf);
return true;
}
if (numemp > 250 )
{ cf = tc1 * 0.007 * 0.050;
alert("Credito formativo = " + cf);
return true;
}
}

</script>

</head>

<body>

<form name="miFormu" onSubmit="return validar(this);">

<p>

<input name="numeroEmpleados" type="text" size="10"> Numero empleados<br>
<input name="TC1" type="text" size="10"> TC1<br>
<input type="submit" name="miSubmit" value="Consultar">

</p>

</form>

</body>
