更改iframe网址更改父窗口网址 [英] changing iframe url changes parent window url
问题描述
我正在使用下一页在iframe中显示url的内容，并根据输入值对其进行更改.
i'm using following page to display content of a url in a iframe and changing it based on input value .
<html>
<head>
<script type="text/javascript">
function changeUrl()
{
var url=document.getElementById('browseurl').value;
if(url!="")
{
if(url.indexOf("http")==-1)
{
url="http://"+url;
}
document.getElementById('browserWnd').src=url;
}
}
</script>
</head>
<body>
<div >
<span>Url</span>
<input id="browseurl" name="browseurl" type='textbox' />
<input id="browse" type='button' value="changeurl" onclick="changeUrl()" />
</div>
<iframe id="browserWnd" src="http://www.coolmath.com/" height="700" width="625"></iframe>
</div>
</body>
</html>
我的问题是浏览iframe中加载的URL的某些内部页面 更改父窗口URL ，而不是iframe中加载...
my problem is browsing some inner pages of an url loaded in iframe changes the parent window url instead of loading in iframe ...
以前的 http://www.coolmath.com/会加载到iframe中，但在浏览某些链接时会在父窗口中加载整个页面.
for ex http://www.coolmath.com/ load in iframe but while browsing some links loads the entire page in parent window.
推荐答案
您可能会注意到，即使像这样的<iframe src='http://www.coolmath-games.com/0-fraction-splat/index.html'></iframe>也会产生相同的结果.这是一种称为框架破坏的技术.在他们页面的代码中:
You may notice that even something like this <iframe src='http://www.coolmath-games.com/0-fraction-splat/index.html'></iframe> results in the same. This is a technique called frame-busting. It's in their page's code:
<script>
<!-- Hide Script
if (top.location != self.location) {
top.location = self.location
}
//End Hide Script-->
</script>
如果您有一台服务器，可以响应HTTP/1.1 204 No Content标头，则可以按照
If you have a server, that can respond with a HTTP/1.1 204 No Content header, you may be able to "deactivate" this frame buster as described here.
