Firepad text editor - text area not showing

问题

I'm following the instruction from here to create a firepad editor.

my code is:

    function init() {
      var firepadRef = getExampleRef();
      var codeMirror = CodeMirror(document.getElementById('firepad-container'), {
        lineWrapping: true
      });
      var firepad = Firepad.fromCodeMirror(firepadRef, codeMirror, {
        richTextToolbar: true,
        richTextShortcuts: true
      });
      firepad.on('ready', function() {
        if (firepad.isHistoryEmpty()) {
          firepad.setHtml('<span style="font-size: 24px;">Rich-text editing with <span style="color: red">Firepad!</span></span><br/><br/>Collaborative-editing made easy.\n');
        }
      });
    }

    function getExampleRef() {
      var ref = new Firebase('https://firepad.firebaseio-demo.com');
      var hash = window.location.hash.replace(/#/g, '');
      if (hash) {
        ref = ref.child(hash);
      } else {
        ref = ref.push();
        window.location = window.location + '#' + ref.key(); // add it as a hash to the URL.
      }
      return ref;
    }
    init();

<div class="page-content">
  <div id="firepad-container">
  </div>
</div>

The problem is i got the button for option as shown in the figure.

but the text field is not coming, even i mention the correct id. The original will be like this.

what i'm doing wrong. is there any other text editor available to work with?

Here is an example of firebase pad:

function init() {
  //// Initialize Firebase.
  var firepadRef = getExampleRef();
  // TODO: Replace above line with:
  // var firepadRef = new Firebase('<YOUR FIREBASE URL>');

  //// Create CodeMirror (with lineWrapping on).
  var codeMirror = CodeMirror(document.getElementById('firepad-container'), {
    lineWrapping: true
  });

  //// Create Firepad (with rich text toolbar and shortcuts enabled).
  var firepad = Firepad.fromCodeMirror(firepadRef, codeMirror, {
    richTextToolbar: true,
    richTextShortcuts: true
  });

  //// Initialize contents.
  firepad.on('ready', function() {
    if (firepad.isHistoryEmpty()) {
      firepad.setHtml('<span style="font-size: 24px;">Rich-text editing with <span style="color: red">Firepad!</span></span><br/><br/>Collaborative-editing made easy.\n');
    }
  });
}

// Helper to get hash from end of URL or generate a random one.
function getExampleRef() {
  var ref = new Firebase('https://firepad.firebaseio-demo.com');
  var hash = window.location.hash.replace(/#/g, '');
  if (hash) {
    ref = ref.child(hash);
  } else {
    ref = ref.push(); // generate unique location.
    window.location = window.location + '#' + ref.key(); // add it as a hash to the URL.
  }
  return ref;
}

init();

html {
    height: 100%;
  }
  body {
    margin: 0;
    height: 100%;
    position: relative;
    
    background-color:#c00000;
  }
  /* Height / width / positioning can be customized for your use case.
         For demo purposes, we make firepad fill the entire browser. */
  #firepad-container {
    width: 100%;
    height: 100%;
    background-color:#c5c5c5;
  }

<body style="border:2px;margin:50px;padding:5px;">
<div id="firepad-container"></div>
</body>

Edit: If you are putting the firepad-container within another div then set a height to that div to avoid height:0px; (and hence text-area being hidden)
