MarkupsCore沒有運行

Question

我已經按照https://developer.autodesk.com/en/docs/viewer/v2/reference/javascript/markupscore/ api來獲取標記，但是它無法運行，這是我在查看器中加載的代碼：

<script src="https://developer.api.autodesk.com/viewingservice/v1/viewers/three.min.js"></script>
<script src="https://developer.api.autodesk.com/viewingservice/v1/viewers/viewer3D.min.js"></script>
var viewerDiv = document.getElementById('MyViewerDiv');
viewer = new Autodesk.Viewing.Private.GuiViewer3D(viewerDiv);
viewer.start(svfUrl, modelOptions, onLoadModelSuccess, onLoadModelError);
var config = {markupDisableHotkeys:false};
markup=new Autodesk.Viewing.Extensions.Markups.Core.MarkupsCore(viewer,config);
console.log(markup);
var markupstatus=markup.enterEditMode();
console.log("markupstatus"+markupstatus);

但它無法運行並在以下位置引發錯誤：markup.enterEditMode（）;

TypeError: Argument 1 of Node.appendChild is not an object.  
...ESIZE_EVENT,this.onViewerResizeBinded),a.container.appendChild(this.svg),this.in...
viewer3D.min.js (42 row，19037 line)

任何幫助深表感謝！

此失敗消息表示未通過經驗法則正確初始化Autodesk.Viewing.Extensions.Markups.Core.MarkupsCore ，因此您只需在console.log(markup);之前添加一行markup.load() console.log(markup); ，它將消失。

這是我的測試代碼，希望您喜歡它〜

var viewer;
Autodesk.Viewing.Initializer(options, function onInitialized() {
  var viewerDiv = document.getElementById( 'viewer' );

  viewer = new Autodesk.Viewing.Private.GuiViewer3D( viewerDiv );
  viewer.start( svfUrl, modelOptions, onLoadModelSuccess, onLoadModelError );
});

function onLoadModelSuccess() {
  var config = { markupDisableHotkeys: false };
  markup = new Autodesk.Viewing.Extensions.Markups.Core.MarkupsCore( viewer,config );

  // Missing line here
  markup.load();

  var markupstatus = markup.enterEditMode();
  console.log( 'markupstatus: ' + markupstatus );
}

function onLoadModelError() {
  console.error( 'Failed to load model' );
}
