如何强制仅在IFrame中加载页面? [英] How to Force the page to be loaded only within an IFrame?
问题描述
我有一组asp.net页面，希望它们仅在从IFrame加载时才可以访问或加载.如果试图通过浏览器地址栏直接访问页面，则该页面根本不会显示或向用户显示消息.
I have a set of asp.net pages which I wish they should only be accessible or loaded when they are loaded from an IFrame. If an attempt is made to access the pages directly via browser address bar then the page should not be displayed at all or display the message to the user.
我尝试使用Cookie和会话，但是它们并不是那么有效，因为一旦创建了cookie/会话，您就可以绕过IFrame直接从浏览器访问页面.
I tried using cookies and sesions, but they are not that effective becuase once the cookie/session is created you can access the pages directly from browser, bypassing IFrame.

推荐答案
这是将脚本放在head标记中的几次更好的例子之一.
This is an example of one of the few times it is better to put the script in the head tag.
<html>
<head>
<title>sandBox</title>
<script type="text/javascript">
if (frameElement == null) {
//change location or close
window.location = "http://stackoverflow.com";
// or window.close();
}
</script>
</head>
<body>
content goes here
</body>
</html>
