Mobile Platform as a Service:Distribute messages

In Android versions earlier than 10.1.0, addNotifyListener could not receive notifications from postNotification if the data field was empty. This restriction was removed in version 10.1.60, and addNotifyListener now accepts empty data.

On Android, broadcasts are sent using LocalBroadcastManager. To receive these broadcasts, you must set up a listener for NEBULANOTIFY_ + name.

Use the postNotification API

AlipayJSBridge.call('postNotification', {
  name:'fortest',
  data:{}
}, function (result) {
  console.log(result);
});

Code example

The following example is a demo of a basic feature:

<h1>Click the buttons below to test</h1>
<p>This only tests the case within the same page. This API can communicate between different applications.</p>

<a href="#" class="btn start">Start Listener</a>
<a href="#" class="btn stop">Stop Listener</a>
<a href="#" class="btn send">Send Notification</a>
<script>
function callback(e){
  alert(JSON.stringify(e));
};

function ready(callback) {
  // If jsbridge is already injected, call it directly
  if (window.AlipayJSBridge) {
    callback && callback();
  } else {
    // If not injected, listen for the injection event
    document.addEventListener('AlipayJSBridgeReady', callback, false);
  }
}
ready(function(){
  document.querySelector('.start').addEventListener('click', function(){
    AlipayJSBridge.call('addNotifyListener', {
      name:'NEBULANOTIFY_TEST_EVENT' // To listen for an event sent from HTML5, you must use the `NEBULANOTIFY_` prefix.
    }, callback);
  });

  document.querySelector('.stop').addEventListener('click', function(){
    AlipayJSBridge.call('removeNotifyListener', {
      name:'NEBULANOTIFY_TEST_EVENT' // To listen for an event sent from HTML5, you must use the `NEBULANOTIFY_` prefix.
    }, function(e){
      alert(JSON.stringify(e));
    });
  });

  document.querySelector('.send').addEventListener('click', function(){
    AlipayJSBridge.call('postNotification', {
      name:'TEST_EVENT', // To listen for an event sent from HTML5, you must use the `NEBULANOTIFY_` prefix.
      data: {
        hello: 'world'
      }
    }, function(e){
      alert(JSON.stringify(e));
    });
  });
});
</script>
