需要哪些javascript包含文件才能获得布局扩展才能在cytoscape中工作？

Question

Cytoscape Javascript绘图软件随附了一些内置布局，但也包含其他创建为“扩展名”的布局。我尝试使用“ klay”布局，这是一个扩展，但我刚遇到JavaScript错误。 （我拥有的代码在内置布局（例如“ cose”）中可以正常工作，但在扩展名方面却无法使用。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/[email protected]/klay.js"></script>   
<script type="text/javascript" src="scripts/cytoscape-klay.js"></script>

所以我在这里做错了什么？一旦有了正确的“ include”文件，代码就应该起作用，因为内置布局的布局使用应与扩展布局相同。谢谢。

跟随demo，我像这样正常工作：

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: {
            id: "n8"
          }
        },
        {
          data: {
            id: "n9"
          }
        },
        {
          data: {

该演示通常使用本地cytoscape-klay文件，因此实际上应该没有问题。该代码对您有用吗？
