i can parent window name in javascript, , don't know how in dart. have tried down cast window.opener window in dart, throw exception. according html5.1 nightly, should expect implemented window basic attribute?
//js version: window.opener.name //dart version: (window.opener ?).name
for popup window.opener can used , iframe window.parent. both return _domwindowcrossframe not support name implement windowbase. that's reason why can't cast window. should use postmessage communicate , exchange information.
see implementation note: its fields , methods can accessed via javascript.
