Don't break the preview on websocket errors

[Acuario]

My html page has a websocket to connect to my server. Obviously in the preview this is not used but it throws an error dialog box which requires an action.
Can websocket errors be ignored as they are not relevant to the preview.

Code that causes the error:

Code: Select all

var host = location.hostname;
function WebSocketConnect()
{
    if ("WebSocket" in window)
    {
        // Open a web socket
        var ws = new WebSocket("ws://" + host + "/ws");
    }
}

I know I can avoid the error by checking if host is an empty string and not attempting the open if it is empty, but I feel it would be preferable not to see the error.

During development, can't you just not use this code? Once you've got the HTML working, then add the socket code?
