Redução de código

Olá Galéra, ... minha dúvida é que sou meio fraco com JS, e gostária de saber se existe uma forma mais eficiênte de fazer o mesmo que o código abaixo faz:

function altera_div(valor)
{

if(valor == 1){

document.getElementById('div_fundo').style.display = "inline";
document.getElementById('div_erro').style.display = "none";
document.getElementById('div_questionario').style.display = "none";
document.getElementById('div_caixa_texto').style.display = "none";
document.getElementById('div_texto_abertura').style.display = "none";
document.getElementById('div_texto_agradecimento').style.display = "none";
document.getElementById('div_texto_questao').style.display = "none";
document.getElementById('div_logo').style.display = "none";
document.getElementById('div_barra_progresso').style.display = "none";

}

else if(valor == 12){

document.getElementById('div_caixa_texto').style.display = "inline";
document.getElementById('div_erro').style.display = "none";

document.getElementById('div_fundo').style.display = "none"

document.getElementById('div_questionario').style.display = "none";
document.getElementById('div_texto_abertura').style.display = "none";
document.getElementById('div_texto_agradecimento').style.display = "none";
document.getElementById('div_texto_questao').style.display = "none";
document.getElementById('div_logo').style.display = "none";
document.getElementById('div_barra_progresso').style.display = "none";

}

else if(valor == 3){

document.getElementById('div_questionario').style.display = "inline";
document.getElementById('div_erro').style.display = "none";

document.getElementById('div_fundo').style.display = "none"

document.getElementById('div_caixa_texto').style.display = "none";
