Cytoscape Javascript 绘图软件带有几个内置布局，还有其他作为“扩展”创建的布局。我尝试使用“klay”布局，这是一个扩展，但我只是收到 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>那么我在这里做错了什么？一旦我有了正确的“包含”文件，代码应该可以工作，因为内置布局的布局的使用应该与扩展布局相同。谢谢。

在演示之后，我让它像这样正常工作：
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: [{

});

该演示通常使用本地的 cytoscape-klay 文件，因此应该没有问题。这段代码对你有用吗？
