I am trying to run this code from this thread in Stack Overflow in Oracle ApeX and it looks as if the setTimeout call is not working as suppose to:

[see thread][1]

<html lang="en">
<head>
<title>Dashboard Example</title>
<style type="text/css">
body, html { margin: 0; padding: 0; width: 100%; height: 100%; overflow: hidden; }
iframe { border: none; }
</style>
<script type="text/javascript">
var Dash = {
    nextIndex: 0,

    dashboards: [
        {url: "http://www.google.com", time: 5},
        {url: "http://www.yahoo.com", t开发者_如何学Goime: 10},
        {url: "http://www.stackoverflow.com", time: 15}
    ],

    display: function()
    {
        var dashboard = Dash.dashboards[Dash.nextIndex];
        frames["displayArea"].location.href = dashboard.url;
        Dash.nextIndex = (Dash.nextIndex + 1) % Dash.dashboards.length;
        setTimeout(Dash.display, dashboard.time * 1000);
    }
};

window.onload = Dash.display;
</script>
</head>
<body>
<iframe name="displayArea" width="100%" height="100%"></iframe>
</body>
</html>

How can I get this call to work in Oracle ApEx v3.0.1?

This problem is nothing to do with Apex - in fact you can take the HTML you posted, save it to a file, and run that file in a browser to test it.

Unfortunately, www.google.com is a URL that will not work with this code, because it contains some "framebusting" Javascript of its own that pops it out of the frame into the browser window, after which your code is no longer running. stackoverflow.com does something similar. If you change the first URL to www.bbc.com for example then it works (on IE anyway) until it gets to stakoverflow.com, when it pops out of the frame.
