vue 集成 vis-network 实现网络拓扑图

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"

// }

];

for (let i = 1; i <= 100; i++) {

//let options = {};

let options = {

},

scaling: {

},

// 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
