如果你在运行代码时出现了 `Uncaught TypeError: Cannot read properties of undefined (reading 'Right')` 的错误,说明在设置 `defaultDirection` 属性时,`go.LayoutDirection` 未被正确加载。
请确保在使用 `ContinuousForceDirectedLayout` 之前,正确地加载了 GoJS 库,并且 `go.LayoutDirection` 被正确定义。可以在 HTML 页面中将以下代码加入到 `<head>` 标签中,以加载 GoJS 库:
```
<script src="https://unpkg.com/gojs/release/go.js"></script>
```
同时,还需要确保在 `ContinuousForceDirectedLayout` 之前,已经定义了 `go` 对象,并且 `go.LayoutDirection` 被正确定义。可以在 `<script>` 标签中添加以下代码:
```
var go = go || {};
go.LayoutDirection = go.LayoutDirection || {};
go.LayoutDirection.Right = 1;
```
这样就可以确保 `go.LayoutDirection` 被正确加载,并且 `defaultDirection` 属性可以被正确设置。
