カスタムボタンの実装

Introduction

Custom buttons can be added to your app's details page. For example, you can add a Download button and/or a Location button. You are responsible for programming the button functionality.

Use cases

Here are some use cases for custom buttons:

• A Download button to allow users to download a copy of the video
• A Location button to allow users to tag their location on videos

Event flow

This diagram shows the event flow for a custom button:

Triggering events

The following events can be used in your plugin code to control custom buttons:

Event data

The following data can be passed with the button event:

Data notes:

• When calling detailsPageRemoveCustomButton

Code example

Here is the JavaScript code syntax used for creating a custom button:

window.postMessage({
  event: 'detailsPageAddCustomButton',
  data: {
    title:  'Test Button',
    font_awesome_icon: 'fa fa-info-circle',
    element_id: 'TEST_BTN_ID'
  }
}, window.location.origin);

Listening for events

The following events are listened for by the player when button events are dispatched in your OTT plugin code:

Event data

The following data is returned when the button clicked event is triggered:

Code example

Here is the JavaScript code syntax used to listen for a button click event:

switch (event.data.event) {
      
  case 'detailsPageExternalButtonWasClicked':
    if (event.data.data.element_id == 'download-button') {
      handleButtonClick('Download button'); 
    };
    if (event.data.data.element_id == 'location-button') {
      handleButtonClick('Location button');
    };
    break;

}

Example

Here is an example of the data object for a button clicked event:

detailsPageExternalButtonWasClicked

Module implementation

The following shows how functions using the side panel are implemented using JavaScript modules. Of course, you may implement your JavaScript in the manner of your choice. Further details on this module implementation can be found in the Implementing OTT Plugin Code Using Modules document.

index.js

Here is our example code:

import { addCustomButtonDetails, addCustomButtonDetailsParams, handleButtonClick } from './button-module.js';

window.addEventListener("message", (event) => {
  const originsAllowed = [
    'your Beacon app URL'
  ];
  if (originsAllowed.includes(event.origin)) {
    switch (event.data.event) {
      
      case 'detailsPageExternalButtonWasClicked':
        if (event.data.data.element_id == 'download-button') {
          handleButtonClick('Download button'); 
        };
        if (event.data.data.element_id == 'location-button') {
          handleButtonClick('Location button');
        };
        break;
        
      case 'onBeaconPageLoad':
        addCustomButtonDetailsParams('Download', 'fa fa-info-circle', 'download-button');
        addCustomButtonDetailsParams('Location', 'fa fa-info-circle', 'location-button');
      break;

    }
  }
},
  false
);

button-module.js

Here is our example code:

const addCustomButtonDetails = () => {
  
      window.postMessage({
        event: 'detailsPageAddCustomButton',
        data: {
          title:  'Test Button',
          font_awesome_icon: 'fa fa-info-circle',
          element_id: 'TEST_BTN_ID'
        }
      }, window.location.origin);
    
    };
    
const addCustomButtonDetailsParams = (pTitle, pFont, pID) => {
  
  window.postMessage({
    event: 'detailsPageAddCustomButton',
    data: {
      title:  pTitle,
      font_awesome_icon: pFont,
      element_id: pID
    }
  }, window.location.origin);

};

const handleButtonClick = (buttonString) => {

  alert('button was clicked ' + buttonString);

};

export { addCustomButtonDetails, addCustomButtonDetailsParams, handleButtonClick };
