js 强制弹出窗口代码研究－又一款代码

复制代码代码如下:
<script language="JavaScript">
var paypopupURL = "http://www.jb51.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>
