强制弹出窗口代码研究－又一款代码

<script language="JavaScript">
var paypopupURL = "http://www.codesky.net";
var randkey = '13'; //bypass IE functions
 
 
function setupActiveX(){
    document.write(' <INPUT ID="autoHit" TYPE="TEXT" ONKEYPRESS="showActiveX()">');
}
 
 
function openActiveX(){
    document.getElementById('autoHit').fireEvent("onkeypress",(document.createEventObject().keyCode=escape(randkey).substring(1)));
}
 
 
function showActiveX(){
    var newWindow=window.open(paypopupURL,'abcdefg','width=200,height=200,top=50,left='+(screen.width-250));
}
 
setupActiveX();
openActiveX();
self.focus();
</script>
