Question

need tips for creating a javascript widget

Answer 1

+1 A:

In your case I would recommend using an <iframe>. It should prevent any javascript conflicts occuring between your frame and the parent website, as well as been widely supported across all major web browsers.

You should then be able to open a popup window using the window.open method. I'd be cautious with popup windows as there is no reliable cross browser method to detect if a popup has been blocked, which may leave users confused.

Answer 2

A:

If it's a popup you can simply open on of those opening the feedback page on your webapp...

<head>
    <script type="text/javascript">
         function mypopup(url) {
              mypopup = window.open(
                 url,  
                 "mypopup",
                 "width=600,height=400,status=yes,scrollbars=yes,resizable=yes"
              );
              mypopup.focus();
         }
    </script>
</head>
<body>
    <a href="#" onclick="mypopup('http://example.com/feedbackform');"&gt;
       Open Feedback Form
    </a>
</body>

Answer 3

+1 A:

Or, if an iframe or popup window are not what you had in mind, you can still do this with AJAX, but you'll need to use JSONP or set the Access-Control-Allow-Origin header in all of your responses.

However, that said, your best bet is probably an iframe. This allows you to roll out bug fixes immediately and doesn't rely on the client to update their client to the latest version.
