推荐答案
如果您想阻止诸如 POP 弹出式广告或来自您在 IFRAME 中展示的网站的内容之类的内容 - 这很容易.
制作 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 等等.但按原样 - 它对我来说一直很好.希望有帮助.
用这个替换你的标准 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>
Framefilter.php
<?php
//Get the raw html.$furl=trim($_GET["furl"]);
$raw = file_get_contents($furl);
$mydomain="http://www.yourdomainhere.com/";
//Kill anoying popups.
$raw=str_replace("alert(","isNull(",$raw);
$raw=str_replace("window.open","isNull",$raw);
$raw=str_replace("prompt(","isNull(",$raw);
$raw=str_replace("Confirm: (","isNull(",$raw);
//Modify the javascript links so they go though a filter.
$raw=str_replace("script type="text/javascript" src="","script type="text/javascript" src="".$mydomain."javascriptfilter.php?jurl=",$raw);
$raw=str_replace("script src=","script src=".$mydomain."javascriptfilter.php?jurl=",$raw);
//Or kill js files//$raw=str_replace(".js",".off",$raw);
//Put in a base domain tag so images, flash and css are certain to work.$replacethis="<head>";
$replacestring="<head><base href='".$furl."/'>";
$raw=str_replace($replacethis,$replacestring,$raw);
//Echo the website html to the iframe.echo $raw;
?>javascriptfilter.php
<?php
//Get the raw html.$jurl=trim($_GET["jurl"]);
$raw = file_get_contents($jurl);
//Note, if trickyness like decode detected then display empty.
if(!preg_match("decode(", $raw)){
//Kill anoying popups.
$raw=str_replace("alert(","isNull(",$raw);
$raw=str_replace("window.open","isNull",$raw);
$raw=str_replace("prompt(","isNull(",$raw);
$raw=str_replace("Confirm: (","isNull(",$raw);
//Echo the website html to the iframe.
echo $raw;
