Re: iframe link to open Safari

Well, you're right, sort of... you'll need to access it via the parent page—a relative path vs. the frame; the following code does that:


<div onclick="parent.widget.openURL('http:// developer.apple.com/');">Click Me.</div>

I reason I had used if (window.widget) is that I had seen that code in several places in the Dashboard Tutorial. though the openURL example does a plain if (widget) test.

No, you _should_ always test to see if window.widget (or in an frame, parent.window.widget) is present. Sorry if I was unclear about that.


a related question is that to write dashboard code that allows testing in Safari, what's the recommended way to test since my understanding is that an undefined variable in JS isn't the same as null. e.g. (typeof(widget) != "undefined") ?

We recommend that you use if(window.widget) statements.

If running in a widget, "window.widget" will evaluate to a non-zero value (an address in memory), which is what's needed for an if statement to evaluate to true. If the you ask for window.widget outside of Dashboard, it's an undefined value, since it's not available in the runtime.

You don't need the "window.xxx."—the call is simply widget.openURL
(url).  The widget object that the Dashboard runtime injects into the
web view is independent of the DOM, so you don't have to trace back
to it, provide a path, etc.

I have a similar situation in 10.4.1.   I display one of two pages
in an iframe -- both come from a server that I control. one is PHP;
the other is vanilla HTML.

 I can use  "if (window.widget) window.widget.openURL(...)" in the
main window of my widget it works fine -- opens a Safari window

however, if I set up a script within an iframe to open a link,
window.widget fails.  so does window.top.widget and
window.parent.widget.

// in iframe
function wclick(link) {
    if (window.top && window.top.widget) {
        window.top.widget.openURL(link.href);
        return false;
    };
    link.target = "_top";
    return true;
}
...
<A href="some link" onClick="return wclick(this)">

clicking on the link works fine in Safari (i.e., displays link in
main window, not the iframe)
but widget displays in "_top" also -- doesn't use openURL.

if window.top isn't the correct way to access main window, what is?
or other workaround?

or is this a bug in current widget?  or somehow considered a
security hole?
