需要哪些 javascript 包含文件才能使布局扩展在 cytoscape 中工作？

Question

Cytoscape Javascript 绘图软件带有几个内置布局，但也有其他创建为 'extensions' 的布局。我尝试使用 'klay' 布局，这是一个扩展，但我只收到 JavaScript 错误。（我的代码在 'cose' 等内置布局中运行良好，但在扩展时失败。这是我使用的包含文件：

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/cytoscape/3.14.0/cytoscape.min.js"></script>
<script src="https://unpkg.com/klayjs@0.4.1/klay.js"></script>   
<script type="text/javascript" src="scripts/cytoscape-klay.js"></script>

那么我做错了什么？一旦我有了正确的 'include' 文件，代码就应该可以工作了，因为对于内置布局和扩展布局，布局的使用应该是一样的。谢谢

在 demo 之后，我让它像这样工作得很好：

document.addEventListener("DOMContentLoaded", function() {
  var cy = (window.cy = cytoscape({
    container: document.getElementById("cy"),

    // demo your layout
    layout: {
      name: "klay"

      // some more options here...
    },

    style: [{
        selector: "node",
        style: {
          "background-color": "#dd4de2"
        }
      },

      {
        selector: "edge",
        style: {
          "curve-style": "bezier",
          "target-arrow-shape": "triangle",
          "line-color": "#dd4de2",
          "target-arrow-color": "#dd4de2",
          opacity: 0.5
        }
      }
    ],

    elements: {
      nodes: [{
          data: {
            id: "n0"
          }
        },
        {
          data: {
            id: "n1"
          }
        },
        {
          data: {
            id: "n2"
          }
        },
        {
          data: {
            id: "n3"
          }
        },
        {
          data: {
            id: "n4"
          }
        },
        {
          data: {

          }
        },
        {
          data: {

          data: {

        },
        {
          data: {
            id: "n9"
          }
        },
        {

demo正常使用的是本地的cytoscape-klay文件，应该没有问题。这段代码对你有用吗？
