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.
