This is a small plugin guide to create your own interaction plugin. It is designed for developers who have web programming skills (e.g. HTML, JavaScript, CSS, etc.).
Note: For interaction plugins, version 0.1.82 or higher is needed.
Basics[edit]
An interaction plugin is nothing more than a simple HTML page that is loaded into a background iframe. You do not even need to add any JavaScript or CSS file. Therefore, any HTML page can be loaded as an interaction plugin (at least if the page does not refuse it via the X-Frame-Options HTTP header). Please see following example screenshot & code.
Screenshot[edit]
Note: The background color of the iframe is transparent.
Code[edit]
<!DOCTYPE html>
<html>
<head>
<title>My Interaction Plugin</title>
<style type="text/css">
h1 {
font-family: sans-serif;
color: white;
}
</style>
</head>
<body>
<h1>My Interaction Plugin</h1>
</body>
</html>
Tasks[edit]
An interaction plugin will not receive any input (i.e. it is not possible to handle key, mouse, or touch events). Therefore, you should not implement any controls or buttons, because they can not be controlled anyway. The only task of an interaction plugin is to handle events, data, or requests (e.g. to load content, playlists, or slideshows from your plugin or to execute specific actions). Generally, an interaction plugin does not contain any UI components. All interactions are managed by the TVXInteractionPlugin interface. Add the JavaScript file http://msx.benzac.de/js/tvx-plugin.min.js to your HTML page to make this interface available. Additionally, add some JavaScript lines to interact with this interface. Please see following example code.
Code[edit]
<!DOCTYPE html>
<html>
<head>
<title>My Interaction Plugin</title>
<style type="text/css">
h1 {
font-family: sans-serif;
color: white;
}
</style>
<script type="text/javascript" src="http://msx.benzac.de/js/tvx-plugin.min.js"></script>
<script type="text/javascript">
function MyHandler() {
this.init = function() {
//Init handler
};
this.ready = function() {
//Handler is ready
};
this.handleEvent = function(data) {
//Handle event
};
this.handleData = function(data) {
//Handle data
};
this.handleRequest = function(dataId, data, callback) {
//Handle request
callback(null);
};
}
window.onload = function() {
TVXInteractionPlugin.setupHandler(new MyHandler());
TVXInteractionPlugin.init();
};
</script>
</head>
<body>
<h1>My Interaction Plugin</h1>
</body>
</html>
API[edit]
Beside the TVXInteractionPlugin interface, the JavaScript file exposes some more classes. Please see Plugin API Reference for more information.
Examples[edit]
Here are some examples that you can use as reference to implement your own interaction plugin. Just open the implementation script or the link from the action syntax and analyze it with your browser developer tools (e.g. Chrome Developer Tools).
Alternatively, if you prefer TypeScript, please have a look at this GitHub project: https://github.com/benzac-de/msx-interaction-plugin-examples.
| Plugin | Implementation Script | Action Syntax |
|---|---|---|
| Template | http://msx.benzac.de/interaction/js/template.js | interaction:load:http://msx.benzac.de/interaction/template.html
|
| Search Example | http://msx.benzac.de/interaction/js/search.js | content:request:interaction:init@http://msx.benzac.de/interaction/search.html
|
| Settings Example | http://msx.benzac.de/interaction/js/settings.js | content:request:interaction:init@http://msx.benzac.de/interaction/settings.html
|
| Observer Example | http://msx.benzac.de/interaction/js/observer.js | content:request:interaction:init@http://msx.benzac.de/interaction/observer.html
