vue 集成 vis-network 实现网络拓扑图的方法

vis.js  网站

https://visjs.org/

vs  code 下安装命令

npm install vis-network

在vue  下引入 vis-network组件

const vis = require("vis-network/dist/vis-network.min.js");require("vis-network/dist/vis-network.min.css");

例子代码使用

let DIR = "/jtopo/";let nodes = [{ id: 1, shape: "circularImage", image: DIR + "server.png" },{ id: 2, shape: "circularImage", image: DIR + "server.png" },{ id: 3, shape: "circularImage", image: DIR + "server.png" },{id: 4,shape: "circularImage",image: DIR + "gather.png",label: "pictures by this guy!"},{ id: 5, shape: "circularImage", image: DIR + "wanjet.png" },{ id: 6, shape: "circularImage", image: DIR + "center.png" },{ id: 7, shape: "circularImage", image: DIR + "cloud.png" },{ id: 8, shape: "circularImage", image: DIR + "center.png" },{ id: 9, shape: "circularImage", image: DIR + "wanjet.png" },{ id: 10, shape: "circularImage", image: DIR + "gather.png" }// { id: 11, shape: "circularImage", image: DIR + "11.png" },// { id: 12, shape: "circularImage", image: DIR + "12.png" },// { id: 13, shape: "circularImage", image: DIR + "13.png" },// { id: 14, shape: "circularImage", image: DIR + "14.png" },// {// id: 15,// shape: "circularImage",// image: DIR + "missing.png",// brokenImage: DIR + "missingBrokenImage.png",// label: "when images\nfail\nto load"// },// {// id: 16,// shape: "circularImage",// image: DIR + "anotherMissing.png",// brokenImage: DIR + "9.png",// label: "fallback image in action"// }];let edges = [{ from: 1, to: 4 },{ from: 2, to: 4 },{ from: 3, to: 4 },{ from: 4, to: 5 },{ from: 5, to: 6 },{ from: 6, to: 7 },{ from: 8, to: 7 },{ from: 9, to: 8 },{ from: 10, to: 9 }// { from: 8, to: 10 },// { from: 10, to: 11 },// { from: 11, to: 12 },// { from: 12, to: 13 },// { from: 13, to: 14 },// { from: 9, to: 16 }];for (let i = 1; i <= 100; i++) {num = i + 10;nodes.push({id: num,label: num.toString()});edges.push({ from: num, to: 10 });}let data = {nodes: nodes,edges: edges};let container = document.getElementById("mynetwork");//let options = {};let options = {nodes: {font: {color: "white", //字体的颜色size: 30 //显示字体大小},scaling: {min: 16,max: 32 //缩放效果比例},borderWidth: 0,color: {border: "white",background: "white" //若是引用图标，背景颜色}},groups: {ws: {//系统定义的形状 dot等 这些官网都可以找到shape: "dot",color: "white"}},edges: {//连接线的样式color: {color: "white",highlight: "white",hover: "#848484",inherit: "from",opacity: 1.0}},layout: {randomSeed: 1 //配置每次生成的节点位置都一样，参数为数字1、2等},physics: {// barnesHut: { gravitationalConstant: -30000 },barnesHut: {gravitationalConstant: -80000,springConstant: 0.001,springLength: 200},stabilization: false//{ iterations: 2500 }},interaction: {// navigationButtons: true,hover: true, //鼠标移过后加粗该节点和连接线selectConnectedEdges: false, //选择节点后是否显示连接线hoverConnectedEdges: false, //鼠标滑动节点后是否显示连接线tooltipDelay: 200,zoomView: true //是否能缩放画布},edges: {shadow: true, //连接线阴影配置smooth: true //是否显示方向箭头// arrows: {to : true }//箭头指向from节点}};that.network = new vis.Network(container, data, options);that.network.on("click", function(params) {});

设置 stabilization: false  可以快速生成10000个节点
