We therefore went ahead and prettied up the logging library that Árni had worked on, re-naming it to log4es to distinguish it from the two existing log4js libraries.

http://lt-fannar:8088/launch/client?JSESSIONID=&Zignal-DmrSelector=Ekioh/db3073ab7ced&Zignal-DmrTypeSelector=Ekioh/Ekioh&Zignal-MacAddress=db3073ab7ced&renderingType=svg&Zignal-AccountSelector=1&Zignal-AccountPassword=1234&Zignal-DmrDriver=ekioh


Update : Redirect now works!

We set up a job scheduler which delegates to a timer adapter using the browser’s window.setTimeout(...) and window.clearTimeout(...) methods (as opposed to what’s needed on SVG browsers without a window object or in unit tests).

We next set up a model for the current playback selection and a pair of listeners for channel changes to:

1. Display the channel-switcher window, and set or reset the timer to hide it again for one second in the future.
2. Do nothing, but set or reset the timer to switch the playing channel for 300ms in the future.

Finally, add a job to repeatedly select a random channel every 3 seconds to trigger everything. To manually trigger channel changes, add the following code to the testbed.html file: <a href="javascript:userInputJob()">random channel!</a>

Finally, a loop will repeatedly wait for the user to click a button, then request a random channel from the server using a synchronous call and set the channel playback selection to that.

The two listeners will log to the firebug console what they would be doing in an actually developed system.

// import com.dustindiaz.publisher
// import tv.zignal.karateka.models.ObjectReferenceModel
// import dwr:interface/ScheduleClientApi

var channelPlaybackModel = new ObjectReferenceModel();

var channelPlaybackListener = function channelPlaybackListener(event) {
    var to = event.to ? event.to.url : "nothing";
    console.info("Ask PlaybackManager to start playing " + to);
}
channelPlaybackListener.subscribe(channelPlaybackModel.changed);

var channelSwitchListener = function channelSwitchListener(event) {
    var to = event.to ? event.to.title : "nothing";
    console.info("Display that we are watching " + to);
}
channelSwitchListener.subscribe(channelPlaybackModel.changed);

for( i=0; i<10; i++ ) {
    alert("Wait for user interaction");
    var channel;
    ScheduleClientApi.getRandomTvChannel({
        async:false,
        callback: function(result) {
            channel = result;
        }
    });
    channelPlaybackModel.set(channel);
}

			We’ve recently added a testbed to the zignal 2 server so javascript developers can write testbed.js files to test whatever library or application code they’re working with and run it in the context of the whole application. This blog is started as a place to publish these testbeds for others to look at, learn from and poach from as needed.

Anyone who feels like they need to post to it should create accounts on blog.industria.com and send the e-mail address to me for adding.
