我想创建一个图形,其中几个节点是“复合”节点,嵌入几个子节点,但不显示它们:应该显示子节点,但应该隐藏化合物。
作为布局,我正在使用cytoscape.js的扩展名dagre-cytoscape。
到目前为止,我已经创建了仅复合节点具有的“ compound”类,并且我尝试仅为该类设置opacity:0或visible:隐藏,但是子节点的这些选项中的每一个也变为不可见。
这是一个无效示例的容器:
<!DOCTYPE html>
<html>
<head>
<meta content="text/html;charset=utf-8" http-equiv="Content-Type">

<script>
window.addEventListener('DOMContentLoaded', function () {
var cy = window.cy = cytoscape({
container: document.getElementById('cy'),
layout: {
name: 'dagre'
},
style: [{

'background-color': 'teal',

}
},
{

style: {
'visibility': 'hidden'
}
}
],
elements: {
nodes: [{
data: {
id: 'n0'
}
},
{
data: {
id: 'n1',
parent: 'parent'
}
},
{
data: {
id: 'n2',
parent: 'parent'
}
},
{
data: {
id: 'parent'
},
classes: 'compound'
}
],
edges: [{
data: {
source: 'n0',
target: 'n1'
}
},
{
data: {
source: 'n0',
target: 'n2'
}
}
]
}
});
});
</script>
</head>
<body>
<h1>cytoscape-dagre test</h1>
<div id="cy"></div>
</body>
</html>
在此示例中,节点n1和n2以及父节点均被隐藏。我想使父项保持隐藏状态,但可以看到n1和n2。
答案 0 :(得分:0)
尝试将复合节点的background-opacity
和border-width
设置为0。
