Firepad 文本编辑器 - 文本区域未显示

Question

我正在按照 here 的说明创建一个 firepad 编辑器。

我的代码是：

    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>

问题是我得到了如图所示的选项按钮。

但是文本字段没有出现，即使我提到了正确的 id。原来会这样

我做错了什么。是否有其他可用的文本编辑器？

以下是 firebase pad 的示例：

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;
  }

<!-- Firebase -->

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

编辑：如果您将 firepad-container 放在另一个 div 中，则将高度设置为该 div 以避免 height:0px;（因此文本区域被隐藏)
