推荐答案
如果您想阻止POP广告或来自某个网站的内容，您将在IFRAME中显示 - 这是相当简单。
If you are wanting to block something like POP up ads or something coming from a website you are showing in an IFRAME - it's fairly easy.
制作iframe指向的 framefilter.php 和 javascriptfilter.php 。
您可以对其进行修改以满足您的需求，例如onload等等等等。
但是，作为/是 - 它对我来说工作了很长时间。希望它有帮助。
Make a framefilter.php and javascriptfilter.php which your iframe points to. You can modify it to meet your needs such as the onload blah blah and etc. But as/is - it's been working fine for me for quite a while. Hope it helps.
用您的标准IFRAME HTML替换：
Replace your standard IFRAME HTML with this:
<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;
?>
javascript filter.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;
}
?>
