我正在使用 cytoscape.js 来显示有向图，我在标签中显示 2 个属性。
我想包装文本，据说这在文档中是可能的，但我无法让它工作。任何人都可以帮助语法吗？
'label': 'data(name)',
'font-size' : 14
'text-wrap': 'wrap/n'
text-wrap似乎不起作用，它会挂起图形显示。
我需要设置"文本最大宽度"吗？
提前致谢
您不能在文本换行 css 属性中添加 ，您正在寻找标签属性：
{
"selector": ".multiline-manual",
"style": {
"text-wrap": "wrap"
}
},
{
"selector": ".multiline-auto",
"style": {
"text-wrap": "wrap",
"text-max-width": 80
}
},
应将这些类之一添加到要包装标签的节点。你可以这样做：
var cy = (window.cy = cytoscape({
container: document.getElementById("cy"),
boxSelectionEnabled: false,
autounselectify: true,
style: [{
selector: "node",
css: {
content: "data(name)",
height: "60px",
width: "60px"
}
},
{
selector: "edge",
css: {
"target-arrow-shape": "triangle"
}
},
{
selector: ".multiline-manual",
style: {
"text-wrap": "wrap"
}
},
{
selector: ".multiline-auto",
style: {
"text-wrap": "wrap",
"text-max-width": 80
}
}
],
elements: {
nodes: [{
data: {
id: "n0",
name: "This is a very long name and all I have to do is to add a class!"
},
classes: "multiline-auto"
},
{
data: {
id: "n1",
name: "Shorter"
},
classes: "multiline-auto"
},
{
data: {
id: "n2",
name: "This shouldn't wrap"
},
classes: "multiline-manual"
},
{
data: {
id: "n3",
name: "This shouldnwrap"
},
classes: "multiline-manual"
}
],
edges: [{
data: {
source: "n0",
target: "n1"
}
},
{
data: {
source: "n1",
target: "n2"
}
},
{
data: {
source: "n1",
target: "n3"
}
}
]
},
layout: {
name: "dagre",
padding: 5
}
}));body {
font: 14px helvetica neue, helvetica, arial, sans-serif;
}
#cy {
