worked perfect, thank you.
only one problem, I do birthday November 11, was born in 1987, I have not done 23 years, but it gives me message that I have 23 years ... do not know if you understood, would give me 22 years because I have not done 23 years yet.

Thank you.

function idade(object, birthDay){
	var now = new Date();
	bD = birthDay.value.split('/');
	if(bD.length==3){
		var born = new Date(bD[2], bD[1]*1-1, bD[0]);
		var age=now.getFullYear() - born.getFullYear();
		var yearBD = new Date(now.getFullYear(), bD[1]*1-1, bD[0]);
		if( now.valueOf() < yearBD.valueOf()  )
			--age;
		document.getElementById("computedAge").value = age;
	}
}
