This should get you started atleast with the effect.
<!DOCTYPE html>
<html>
<head>
<style>
div { background:#de9a44; margin:3px; width:80px;
height:40px; }
#one { background:#de9a44; margin:3px; width:80px;
height:40px; display:none; }
</style>
<script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
<div id="one"></div>
<div></div>
<div></div>
<script>
//sets a timer to 1sec
$(document).ready(function () {
window.setInterval(yourfunction, 1000);
});
//goes to a php file and return data to be appended to your div.
function yourfunction() {
$.get("test.php", function(data){
$("#one").html(data)
$("#one").slideDown("slow");
});
}
</script>
</body>
</html>
timer thanks to Kristof Claes and here more info on the jquery get() function. My recommendation for you is to map out a logic of what you want to accomplish, and search for how it might be called and start forming piece by piece your result..That's what I do, I'm no expert in jquery but i have an idea and thanks to great people in in S.O. and google I am able to accomplish awesome things.
