我正在使用Cytoscape-JS通过力导向的布局可视化（相当小的）图形。布局算法本身不太重要。目前，我只是做这样的事情（顺便说一下，我正在使用Typescript）：
this.cyLayout = this.cytoscape.elements().createLayout({
name: 'cola'
});
this.cyLayout.run();
有没有一种方法可以具有连续的布局，这意味着每当我拖动一个节点时，都应该连续更新布局，并且网络应该根据力导向算法的规则再次稳定下来。我已经在Google上搜索了很多，但似乎找不到解决方法。在我看来，这是非常标准的行为（默认情况下其他库提供此行为），并且应该可以通过一个简单的选项对其进行配置。
非常感谢您提供解决方案，在此先感谢您！
如果您想使用cola.js，实际上有一个用于此目的的layout属性。
您可以查看cola.js GitHub page，在其中可以找到infinite: true选项。这将无限地继续进行布局计算，并且可以完成您想要的操作：
document.addEventListener("DOMContentLoaded", function() {
var cy = (window.cy = cytoscape({
container: document.getElementById("cy"),
autounselectify: true,
boxSelectionEnabled: false,
layout: {
name: "cola",
infinite: true
},
