Fix cross-origin error in File Mode

[w00000dy]

Hi,
when you use the UI in File Mode the Peek-Button does not work because of this error:

To fix this, I simply changed line 48 in liveviewws.htm from

var ws = top.window.ws;

to

var ws;

.

I'm a bit confused why you did implement it like this. As far as I know, top.window.ws is the same as ws. Or am I wrong here?

Anyway, I tested File Mode and now I don't get this error anymore and the Peek-Button now works again:

Also in Online Mode Peek still works.

Hey!
Since the liveview is loaded in an iframe, top.window.ws will attempt to use the WebSocket connection of the parent page (UI), which puts less strain on the ESP. Your change will open a second WS connection instead.
I've pushed an alternate solution, a try/catch block that will only open a second connection in File mode.

Hi!
Thanks for your explanation.
I think your implementation is a good solution here.
