Mascara para data(resovi e estou passando para outros membros)

<script language=JavaScript>

function formatar(src, mask) {

	var i = src.value.length;

	var saida = mask.substring(i,i+1);

	var ascii = event.keyCode;

	if (saida == "A") {

 if ((ascii >=97) && (ascii <= 122)) { event.keyCode -= 32; }

 else { event.keyCode = 0; }

	} else if (saida == "0") {

 if ((ascii >= 48) && (ascii <= 57)) { return }

 else { event.keyCode = 0 }

	} else if (saida == "#") {

 return;

	} else {

 src.value += saida;

 if (saida == "A") {

 if ((ascii >=97) && (ascii <= 122)) { event.keyCode -= 32; }

 } else { return; }

	}

}
