从主窗口隐藏iframe

Question

I have 2 <iframe> on my main HTML form.

These <iframe> are loaded from different external domains. Sometime external server goes offline and user see The page can't be dispayed message on my page.

Is there a way to hide these <iframe> when target server is not available?

Answer 1

You can use onload event to display iframe content. Make iframe invisible by default and set visible in onload event,

Answer 2

您可以为load事件设置一个侦听器，如果在特定时间段内未调用此事件，则可以隐藏框架。
