JS checks whether the webpage is in iframe or frame

Many methods provided on the Internet are implemented by judging whether the current window is the same as the top window.

The Code is as follows:

If (top! = This ){

// Process in frame

}

However, this script does not distinguish frame from iframe.

When using the script, I encountered a strange problem in IE: the page is normal only when the iframe has a problem in frame. In addition, Firefox and Chrome are both normal. I don't want to comment on IE anymore. I finally found the method on MSDN to determine whether the current page is in iframe. The script is as follows:

If (self. frameElement. tagName = "IFRAME "){

// Process the page in iframe

}
