Edit: As of 2018, this solution no longer works. So you are back to opening about:blank in a new window and adding content to it.

Don't "write" to the window, just open it with the contents you need:

var data = "
This is 'myWindow'
";
myWindow = window.open("data:text/html," + encodeURIComponent(data),
                       "_blank", "width=200,height=100");
myWindow.focus();
