使用上面@deceze提到的javascript代码(我将其粘贴在下面)，

Using the javascript code that @deceze mentioned above (I pasted it in below),

if (parent.frames.length > 0) { ... }

如果以上代码注意到该页面显示在iframe中，则通过ajax调用调用"IAmInIFRAME.php"(仅作为示例).

If the above code noticed the page was displayed within iframe, then call 'IAmInIFRAME.php'(just example) via ajax call.
