查看本地文件时如何加载扩展

Question

我正在使用取自 viewer-javascsript-offline.sample

的示例

我有一个使用 nodejs 教程 (link) 创建的扩展，我使用教程代码注册了该扩展。但是，当我使用离线查看器代码示例（使用 viewer3D 而不是 viewingApplication）尝试相同的操作时，我无法查看扩展程序的按钮。

注意：我可以保证 handleselectionextension.js 工作正常，因为我已经在教程版本中使用它了。

代码：
index.css 和 index.html

.handleSelectionToolbarButton {
  background-image: url(https://github.com/encharm/Font-Awesome-SVG-PNG/raw/master/white/png/24/object-group.png);
  background-size: 24px;
  background-repeat: no-repeat;
  background-position: center;
}

      'document': "0/1/Design.svf",
      'extensions': ["HandleSelectionExtension"]
    };
    Autodesk.Viewing.Initializer(options, function() {
      viewer.start(options.document, options);
    });

扩展配置不适用于 Initializer，您必须像这样将其传递给查看器构造函数的第二个参数：

var config3d = {
    'extensions': ["HandleSelectionExtension"]
};

var myViewerDiv = document.getElementById('MyViewerDiv');
var viewer = new Autodesk.Viewing.Private.GuiViewer3D(myViewerDiv, config3d);

var options = {
  'env': 'Local',
  'document': "0/1/Design.svf"
};

Autodesk.Viewing.Initializer(options, function() {
  viewer.start(options.document, options);
});
