Question

Fade-in image on page load using scriptaculous / prototype

Asked by: freshwaterwest

I'm trying to find how to simply fade-in or slide-in an image on page load using scriptaculous/prototype (avoid using flash for such a simple requirement)-

I'm sure there is probably a very simple solution but unfortunately my lack of javascript knowledge is preventing me from sussing it out.

I have the javascripts loaded correctly as I also have a vertical accordion menu which is working fine.

Tried using a couple of examples online (body onload and also a head script) to affect an id either on a div or an image (with a display:none; style added directly to the div/image), but can't get any to work.

thanks

sorry, think I' might have misled you by adding to jscript section - I already have prototype scriptaculous effects etc. loaded - so would prefer to utilise the effects within these..

<script type="text/javascript" src="javascript/prototype.js"></script>
<script type="text/javascript" src="javascript/effects.js"></script>
<script type="text/javascript" src="javascript/accordion.js"></script>

I'm simply looking to have an image fade-in or slide-down when the page first loads

i.e. Effect.Appear - just not sure how to use it on page load

thanks

 

by: hieloPosted on 2008-02-18 at 09:51:13ID: 20921953

You need to "schedule" a function to be executed upon page load:
window.onload = begin;

You will also need to define your function:
function begin()
{
new Effect.Appear(document.getElementById('thePictureId'));
}

This is what I have tried based on your comment and previous attempts, not sure what I need to do here to make it work:


<script type="text/javascript">
window.onload = begin;

function begin()
{
new Effect.Appear('pageimage', { duration: 3.0 });}

</script>
</head>

<body>
<div id="container"><img id="pageimage" style="display:none;" src="images/about_back.jpg" alt="About us" width="800" height="170" />

You might try JQuery, instead of prototype. www.jquery.com

Then it would be very simple: 

$('#element').fadeIn();

probably smaller code too perhaps?
