实现打开网站后自动弹出新网页（代码片段）

<script type="text/javascript">window.onunload = function(){window.open("http://www.baidu.com");}</script>

代码

<script language="javascript">
function setCookie(by_itxmt_com, value, expire){window.document.cookie = by_itxmt_com + "=" + escape(value) + ((expire == null) ? "" : ("; expires=" + expire.toGMTString()));}
function getCookie(by_itxmt_com){var search = by_itxmt_com + "=";if(window.document.cookie.length > 0){offset = window.document.cookie.indexOf(search);if(offset != -1){offset += search.length;end = window.document.cookie.indexOf(";", offset)  if(end == -1)
end = window.document.cookie.length;return unescape(window.document.cookie.substring(offset, end));}}return null;}
function register(by_itxmt_com){var today = new Date();var expires = new Date();
expires.setTime(today.getTime() + 1000*60*60*24);//时间格式：1000*60*60*24代表24小时
setCookie("itxmt_com", by_itxmt_com, expires);}
var exitURL="https://by.itxmt.com/";//这个地方放置你的HTML地址
function openWin(){var c = getCookie("itxmt_com");if(c != null){return;}register("itxmt_com");var featureStr="''";
featureStr="";//这里是设置你上面的HTML弹出的高度和宽度的
self.focus();var ExitWindow = window.open(exitURL,'', featureStr);ExitWindow.focus();}
setTimeout("openWin()",3000);//3秒后弹出
window.focus();
</script>
