Titanium Alloy - Create view without controller and access components inside that view


I have a Titanium Alloy view called overlay.xml that doesn't have a controller. I am creating it in another controller called episode.js and adding it to a container in episode.xml. I'm doing this in order to make overlay.xml into reusable view that can be added anywhere.

For example

episode.js

// create the overlay view
var overlay = Alloy.createController("overlay").getView();
// add it somewhere in episode.xml
$.episodeImage.add(overlay);

Inside overlay.xml I have several components, like buttons and labels, that I'd like to access in Episode View to add event listeners to. For example:

overlay.xml

<Alloy>
    <View id="overlay">
        <Button id="theButton" title="Click Me!" />
        <Label id="theLabel" text="I am a label" />
    </View>
</Alloy>

And then in episode.js for example:

var overlay = Alloy.createController("overlay").getView();
$.episodeImage.add(overlay);

// EXAMPLE: Get the button from overlay.xml and add an event listener
$.theButtonFromOverlayXML.addEventListener("click", function () {
    alert("You clicked the button from overlay.xml!"):
});

Is it possible to do this?


Solution

  • Yes, you can access views through their ids in another controller. The only need to assign controller object and view object to two different variables:

    episode.js

    var overlay = Alloy.createController("overlay");
    
    overlay.theButton.addEventListener('click', function() {
        alert('You clicked the button from overlay.xml!');
    });
    
    var overlayView = overlay.getView();
    $.episodeImage.add(overlayView);
    // shorter version
    $.episodeImage.add( overlay.getView() );
