有没有办法在 cytoscape.js 的样式选择器中使用节点度数？
Is there a way to use node degree in a style selector in cytoscape.js?
我希望每个节点的背景颜色由节点的度决定。有没有办法在初始化时将其设置为样式规则？我正在寻找类似以下内容的内容：
var cy = cytoscape({
...
style: [
{
selector: 'node[degree < 3]',
style: {
'background-color': 'red'
}
},
{
selector: 'node[degree >= 3]',
style: {
'background-color': 'green'
}
},
...
]
...
});
关于这是否可能有任何想法吗？
文档说明了这一点：
- [[...]]（元数据括号）：使用双方括号代替方括号来匹配元数据而不是数据
- [[degree > 2]] 匹配度数大于 2
的元素
- 支持的属性包括度、入度和出度
所以只需使用 node[[degree > 3]] 而不是 node[degree > 3] 就可以了：
document.addEventListener("DOMContentLoaded", function() {
var cy = (window.cy = cytoscape({
container: document.getElementById("cy"),
autounselectify: true,
boxSelectionEnabled: false,
layout: {
name: "cola",

fit: false
},
style: [{
