2godoom,
А самому проверить? )))
<div id="show">123</div>
<div id="test">123</div>
<script type="text/javascript">
var show = document.getElementById('show');
var test = document.getElementById('test');
function checkLable(b, a) {
b.innerHTML += b.id + ' ' + a +'<br />';
b.style.backgroundColor = a % 2 ? "#f00" : "";
a-- && window.setTimeout( function () { checkLable(b, a) }, 300)
};
checkLable(test, 7)
checkLable(show, 6)
</script>
