ajax? why use js + xml?

[ReDucTor]

sorry about messy post using on screen keyboard coz mine broke.

 

but why isnt ajax just..

 

function ajax(){
document.write("<script language=\"javascript\" src=\"ajax.php\" />");
t=setTimeout("ajax()",1000)
}
ajax()

 

whats wrong there?

Wouldn't that add the same script the the page indefinitely? Redefining functions etc. and generally causing errors. Not sure how asynchronous that is either...

 

Oh, and wrong forum. Moved to AJAX forum.

You would just output

e.g.

alert('new message');
