I wrote the following codes where customised by myself. However their sources belong to their rightful owners, DO NOT claim them as your own work. Both scripts have been tested and work.
1. Automatic AJAX window in center of page
Place the following script between the header tags
Code
<script type="text/javascript">
window.onload = function ajaxauto(){
var ajax_data = 'content goes here'; new _uWnd('myname','title',300,350,{shadow:1,autosize:1,modal:0,close:1},ajax_data);}
</script>
2. Automatic AJAX window in bottom right of your page
Place the following script between the header tags
Code
<script type="text/javascript">
window.onload = function ajaxbtm() {_uWnd.alert('Content goes here','Title',{w:500,h:100,tm:10000});}
</script>
'Content goes here' - The content
'Title' - The title
300,350 / w:500,h:100 - The size measured in pixels (px)
tm:10000 - Duration before window closes
