Does Edge's IE compatibility mode also support the "channelmode" property of window.open?

Question

I need to open a maximized new window when making a website, but the window opened with "channelmode=yes" of window.open in Edge's IE compatibility mode is not a maximized window.
The size of the window is the same as the window opened without "channelmode=yes". Does Edge's IE compatibility mode do not support the "channelmode" attribute of window.open? Was it not supported at the beginning or was it not supported at the beginning of a certain version?
Thanks.

Hi @Archer ,

According to your description, I test the window.open function with channelmode. But the result I got is different from yours. The window opened in IE-mode is larger than the normal running Edge, although it is still not in full screen state. Therefore, I think it actually supports channelmode when using Edge-IE-mode, but the effect is not very satisfactory.

If you need to maximize the opened window, you can use javascript to achieve a similar function, like this:

var params = [  
        'height=' + screen.height,  
        'width=' + screen.width,  
        'channelmode=yes'  
        ].join(',');  
  
 var popup = window.open('http://www.google.com', 'popup_window', params);  
 popup.moveTo(0, 0);  

Hope this can help.

Best regards,
Xudong Peng
