修改屬性面板有幾種方法，

1. 最簡(jiǎn)單的就是直接操作當(dāng)前的屬性面板，比如：

  var propertyPanel = _viewer.getPropertyPanel(true)
  propertyPanel.setTitle('My Panel')
  propertyPanel.addProperty('test', 'john', 'new cat', null)
  propertyPanel.setVisible(true)

1. 如果需要對(duì)屬性面板整體來做調(diào)整，那么常見的方法是重載默認(rèn)的屬性面板，比如：

AutodeskNamespace('Viewing.ClassroomTrainning')

Viewing.ClassroomTrainning.AdnPropertyPanel = function (viewer) {
  var _panel = this
  var _viewer = viewer
  var _selectedNodeId = ''

  Autodesk.Viewing.Extensions.ViewerPropertyPanel.call(
    _panel,
    _viewer)

  _panel.setNodeProperties = function (nodeId) {
    Autodesk.Viewing.Extensions.ViewerPropertyPanel.prototype.setNodeProperties.call(
      _panel,
      nodeId)

    _selectedNodeId = nodeId
  }

  _panel.setProperties = function (properties) {
    Autodesk.Viewing.Extensions.ViewerPropertyPanel.prototype.setProperties.call(
      _panel, properties);

      var insTree = _viewer.model.getInstanceTree();
      var nodeName = insTree.getNodeName(_selectedNodeId);

    $.ajax({
      url: '/db/price/'+nodeName,
      type: 'GET',
      success: function (data) {
        console.log('successfull get price: ' + data)
        _panel.addProperty(
          'Node Price', // property name
          data, // property value
          'Database Information') // group name
      }
    })
  }
}

Viewing.ClassroomTrainning.AdnPropertyPanel.prototype =
  Object.create(
    Autodesk.Viewing.Extensions.ViewerPropertyPanel.prototype)

Viewing.ClassroomTrainning.AdnPropertyPanel.prototype.constructor =
  Viewing.ClassroomTrainning.AdnPropertyPanel

然后，將重載后的屬性面板設(shè)置為當(dāng)前的屬性面板，修改模型結(jié)構(gòu)的點(diǎn)擊事件來使用自定義的屬性面板：

Viewing.ClassroomTrainning.Extension.prototype.onGeometryLoaded = function () {
  var panel = new Viewing.ClassroomTrainning.AdnPropertyPanel(_viewer)
  _viewer.setPropertyPanel(panel)

  // Add onClick event for Model Structure Panel
  var structruePanel = _viewer.modelstructure
  structruePanel.onClick = _self.onModelStructureClick
}

Viewing.ClassroomTrainning.Extension.prototype.onModelStructureClick = function (node, e) {
  var propertyPanel = _viewer.getPropertyPanel(true)
  if (propertyPanel && propertyPanel.isVisible()) {
    propertyPanel.setNodeProperties(node)
  }
}
