Need to set 1 span's style to display:block on page load for an image gallery made up of span's set to display:none
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.s开发者_开发问答tyle.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.
The simple, breezy way is to do this:
<body onload="showSpan('link1');">
The trouble here is that the onload event attached to body that way is executed a little late in the page loading (After all the parts-- including images-- are loaded) so it'll be murder for your dial up users. jQuery implements a much better way:
$(document).ready(function () {
showSpan('link1');
});
If you're not using jQuery, then someone here much wiser than I more than likely knows the correct way to do it using "proper" JavaScript, I don't remember the event name that jQuery uses off the top of my head.
