Olyan HTML kód kellene nekem - ha van - ami letiltja a felugró ablakokat?

<script language='javascript'>

NS_ActualOpen=window.open;

function NS_NullWindow(){this.window;}

function

NS_NewOpen(url,nam,atr){return(new NS_NullWindow());}

window.open=NS_NewOpen;

</script>

vagy

<script language="JavaScript">

// Source: koszalka.com

function blockPopup(){return true;}

window.popup = blockpopup;}

</script>
