suppose on window A I do

```
var newWindow = window.open('url', 'name', 'width=100');

```

and open a new window (call it window B)

then on window B I get a reference to the opener window (window A)

```
var opener = $(window.opener)

```

is there a way to use the opener variable above to detect from window B when window A gets refreshed and/or finished refreshing?
