如果你想阻止像POP广告这样的东西或来自你在IFRAME中展示的网站的东西 - 这很容易.
制作一个iframe指向的framefilter.php和javascriptfilter.php.您可以修改它以满足您的需求,例如onload blah blah等等.但是/是 - 它已经很好地为我工作了很长一段时间.希望能帮助到你.
用以下内容替换标准IFRAME HTML:
<IFRAME SRC="http://www.yourdomainhere.com/framefilter.php?furl=http://www.domainname.com" WIDTH=1000 HEIGHT=500>
If you can see this, your browser doesn't
understand IFRAMES. However, we'll still
<A HREF="http://www.domainname.com">link</A>
you to the page.
</IFRAME>

$raw=str_replace("script src=","script src=".$mydomain."javascriptfilter.php?jurl=",$raw);
//Or kill js files
//$raw=str_replace(".js",".off",$raw);
//Put in a base domain tag so images, flash and css are certain to work.

一个很老的问题,但我想我会提供一个更新的解决方案,因为这是谷歌的最佳结果。
如果您想阻止 iframe 打开窗口,您可以在 iframe 上使用新的 HTML5“沙箱”属性。
https://developer.mozilla.org/en/docs/Web/HTML/Element/iframe
这应该可以防止它做任何事情(除了运行页面正常运行可能需要的 javascript):
<iframe sandbox="allow-scripts" src="your/url/here"></iframe>
