<h3>操作示例</h3>
<h4>1.增加事件监听</h4>
<h5>接口</h5>
<ul>
<li><code>addEventListener(eventType, callback)</code> 增加事件监听</li>
</ul>
<h5>参数</h5>
<ul>
<li>eventType : <code>BCore.Static.EventType.event</code> - Bcore注册静态变量事件类型</li>
<li>callback : <code>Function</code> - 回调函数</li>
</ul>
<h5>示例</h5>
<pre><code class="language-javascript">let mApplication3DConfig = new BCore.Application.Application3DConfig();
let mApplication3D = new BCore.Application.Application3D(mApplication3DConfig);
let mViewer3D = new BCore.Viewer.Viewer3D('bcorecontanier', new BCore.Viewer.Viewer3DConfig());
mApplication3D.addViewer3D(mViewer3D);
//必须先注册'ViewAdded'事件 再调用 Viewer3D.initViewer3D()
mApplication3D.addEventListener(BCore.Static.EventType.ViewAdded,()=&gt;{mViewer3D.addModel('fileId')});
mViewer3D.initViewer3D('092596df957f4b4caa52397e61724fe7');
let myEventCallback = ()=&gt;{console.log('ModelAdding')};
mViewer3D.addEventListener(BCore.Static.EventType.ModelAdding,myEventCallback);</code></pre>
<h4>2.移除事件监听</h4>
<ul>
<li><code>removeEventListener(eventType, callBack)</code> 移除事件监听</li>
</ul>
<h5>参数</h5>
<ul>
<li>eventType : <code>BCore.Static.EventType.event</code> - Bcore注册静态变量事件类型</li>
<li>callback : <code>Function</code> - 回调函数</li>
</ul>
<h5>示例</h5>
<pre><code class="language-javascript">let mApplication3DConfig = new BCore.Application.Application3DConfig();
let mApplication3D = new BCore.Application.Application3D(mApplication3DConfig);
let mViewer3D = new BCore.Viewer.Viewer3D('bcorecontanier', new BCore.Viewer.Viewer3DConfig());
mApplication3D.addViewer3D(mViewer3D);
//必须先注册'ViewAdded'事件 再调用 Viewer3D.initViewer3D()
mApplication3D.addEventListener(BCore.Static.EventType.ViewAdded,()=&gt;{mViewer3D.addModel('fileId')});
mViewer3D.initViewer3D('092596df957f4b4caa52397e61724fe7');
let myEventCallback = ()=&gt;{console.log('ModelAdding')};
mViewer3D.addEventListener(BCore.Static.EventType.ModelAdding,myEventCallback);
mViewer3D.removeEventListener(BCore.Static.EventType.ModelAdding,myEventCallback);</code></pre>
