This is my chats' sign out function. It works perfectly when I open the chat on a page alone.e.g. www.abc.com/chatbox/index.htm But when its with other elements in the same page using iFrame it will not work.e.g.www.abc.com/chat&paintIframe.htm

Bu benim kodudur

<script type="text/javascript">
function singout(){

data="user=" + "" +"&oper=signout"
Ajax_Send("POST","chatbox/users.php",data,checkSignOut);
alert("Singout");
return false;     
}
</script>

ve burada ben onu aramak

<iframe height="300" width="600" frameborder="0" src="chatbox/index.htm"     onbeforeunload="singout()"></iframe> 

Herhangi bir yardım takdir ..
