ImageRotatorApi – JW Player

The Image Rotator contains a small javascript API. It can be enabled by setting the flashvar enablejs=true. When set, the rotator can be controlled by calling the function sendEvent() on the rotator. Additionally, the rotator will automatically send updates to a global getUpdate() javascript function.

enablejs ¶

Here's an example of an embed code that enables the rotator javascript API:

    src="rotator.swf" 
    width="300" 
    height="300" 
    flashvars="file=playlist.xml&enablejs=true"
    name="rotator"
    id="rotator"
/>

    src = "rotator.swf"
    width = "300"
    height = "300"
    FlashVars = "file = playlist.xml & enablejs = true"
    nama = "rotator"
    id = "rotator"
/>

    src="rotator.swf" 
    width="300" 
    height="300" 
    flashvars="file=playlist.xml&enablejs=true"
    name="rotator"
    id="rotator"
/>

The enablejs=true flashvar turns on the API. The name and id flashvar give the rotator a unique ID in the HTML DOM, so its sendEvent function can be called.

sendEvent ¶

The sendEvent function can be directly called upon the rotator. If thename and id of the rotator is set to rotator (as in the above embed code), events can be sent like this:

function next() {
    // make the imagerotator jump to the next image.
    document.getElementById('rotator').sendEvent('next');
};

    / / Make the leap to the next image imagerotator.
    document.getElementById ('rotator') sendEvent ('next').;
};

    // make the imagerotator jump to the next image.
    document.getElementById('rotator').sendEvent('next');
};

    // make the imagerotator jump to the next image.
    document.getElementById('rotator').sendEvent('next');
};

The following events are available:

• getlink (index): redirect the browser to the link of photo number index.
• next: jump to the next image.
• playitem ( index ): jump to image number index .
• playpause: pause or resume the rotator (acts like a toggle).
• prev: jump to the previous image.
• volume (percent): set the volume of the audiotrack to percent (provided you use an audiotrack).

getUpdate ¶

When the enablejs=true flashvar is set, the rotator automatically sends status updates to javascript. In order to receive those, you need to define a javascript function called getUpdate on your page:

function getUpdate(type,parameter1,parameter2) { 
    alert('Received a '+type+' update from the rotator');
    alert('Parameters: '+parameter1+' - '+ parameter2);
};

    alert ('Accept' + type + 'update of the rotator');
    alert ('Parameter:' paramater1 + + '-' + parameter2);
};

    alert('Received a '+type+' update from the rotator');
    alert('Parameters: '+parameter1+' - '+ parameter2);
};

The rotator sends the following types of updates:

• item (index): the rotator switches to image number index.
• load (percent): the current image is loaded for percent percent.
• size (width,height): the current image has the dimensions width by height.
• state (index): the current playback state is state, whereby the state can be the following:
  • 0: the rotatot is paused.
  • 1: the rotator is buffering for playback.
  • 2: the rotator is playing.
  • 3: the rotator has completed playback.
  • 4: the rotator is idle; has not started yet.
• time (elapsed,remaining): the rotator has played the current image for elapsed seconds and has remaining seconds to go yet.
• volume (percent): the current volume of the rotator is percent.
