AJAX-Prinzip mit PHP

[omata]

Versuch es doch mal so...

Code:

<script type="text/javascript">
function show (elem) {
  if (document.getElementById)
    document.getElementById(elem).style.visibility = "visible";
}

function hide (elem) {
  if (document.getElementById)
    document.getElementById(elem).style.visibility = "hidden";
}
</script>

Gruss
