i have some javascript in the head of a page that controls an image gallery where the user clicks a thumbnail image and a larger image and some text are revealed in a span. there are 10 of these thumbnails per page and i need to find out how to set the 1st thumbnail's hidden span to "block" on page load.
<script type="text/javascript">
function hideSpan(spanName) {
var obj = document.getElementById(spanName);
obj.style.border="0px";
obj.style.color="#fff";
obj.style.display="none";
obj.style.left="333px";
obj.style.padding="0";
obj.style.position="absolute";
obj.style.top="55px";
obj.style.width="244px";
}
function showSpan(spanName) {
var spanEl, count = 1;
while(spanEl = document.getElementById('link' + count++)){
spanEl.style.display = 'none';
}
var obj = document.getElementById(spanName);
obj.style.display="block";
}
</script>
any help with this is VERY appreciated thank you.
