Custom message

Hello,

Can I customize alert function in JavaScript to show buttons other than "ok". such as "yes and no" or "ok cancel" ...

Alert:

<SCRIPT LANGUAGE="JavaScript">
<!--
window.alert("Type your message here...")
// -->
</SCRIPT>

Prompt

<SCRIPT LANGUAGE="JavaScript">
<!--
var NAME = prompt("Type your message here...","")
//ACTION
")
// -->
</SCRIPT>

Confirm

<SCRIPT LANGUAGE="JavaScript">
<!--
if (!confirm(Type your message here...)){
//ACTION
}
// -->
</SCRIPT>
