Is there a way to verify the success of a Firebase push event upon submitting a form?

Here is the code for my polymer form and JavaScript. It works well in pushing data. What I would like to achieve is a way to verify if the push operation was successful or not. If it was successful, I want to hide the form and display a confirmation message, or redirect users to another page.

My question is: How can I check if a Firebase push request was successful?

<form is="iron-form" method="get" action="firebaseURL/events" id="eventsDemo">
  <paper-input name="name" label="Name" required auto-validate></paper-input>
  <paper-input name="password" label="Password" type="password" required auto-validate></paper-input>
  <paper-checkbox name="read" required>You must check this box</paper-checkbox><br>
  <paper-button raised onclick="_delayedSubmit(event)" disabled id="eventsDemoSubmit">
    <paper-spinner id="spinner" hidden></paper-spinner>Submit</paper-button>
  <div class="output"></div>
</form>   
<script>
function _delayedSubmit(event) {
    event.preventDefault();
    spinner.active = true;
    spinner.hidden = false;
    eventsDemoSubmit.disabled = true;
    // Simulate a slow server response.
    setTimeout(function() {
      //Polymer.dom(event).localTarget.parentElement.submit();
      var firebase = new Firebase(eventsDemo.getAttribute('action'));
      firebase.push(eventsDemo.serialize());
    }, 100);
  }
</script>

When using Firebase's write methods, you have the option to include a completion listener that will be triggered once the data has been successfully written to the server. According to the details provided in the guide on completion callbacks:

To receive confirmation that your data has been stored, you can attach a completion callback to both set() and update() methods. This callback will notify you when the writing process is completed. In case of any errors during the operation, the callback function will receive an error object explaining the cause of failure.

dataRef.set("I'm adding new data", function(error) {
  if (error) {
    alert("Failed to save data: " + error);
  } else {
    alert("Data saved successfully.");
  }
});

For comprehensive guidance, I suggest going through the Firebase web programming guide thoroughly. It contains valuable insights that can prevent potential issues in the future.

Hey there Frank! I appreciate your input. Here is a revised edition of @Frank's solution tailored for ES6 using arrow functions:

updatedDataRef.store("I am updating the data", failure => {
  if (failure) {
    alert("There was an issue saving the data: " + failure);
  } else {
    alert("Data saved successfully!");
  }
});
