怎么在vue中利用vis-network实现网络拓扑图-创新互联
本篇文章为大家展示了怎么在vue中利用vis-network 实现网络拓扑图，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。
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 data = {
nodes: nodes,

let container = document.getElementById("mynetwork");
//let options = {};
let options = {
nodes: {

Vue是一套用于构建用户界面的渐进式JavaScript框架，Vue与其它大型框架的区别是，使用Vue可以自底向上逐层应用，其核心库只关注视图层，方便与第三方库和项目整合，且使用Vue可以采用单文件组件和Vue生态系统支持的库开发复杂的单页应用。
