通过React.js将vis.js网络渲染到容器中

Question

如何将vis.js网络渲染到具体的html容器中？
我尝试了以下内容,但它不起作用:

<div id="network">
   {new vis.Network("network", data, options)}
</div>

或者我应该按照以下方式呈现它？

ReactDOM.render(<App />, document.getElementById('app'));
ReactDOM.render(<Network />, document.getElementById('network'));

虽然元素"app"和"network"位于包装器html容器中.

我希望将vis.js网络呈现到根文档中的解决方案:

 ReactDOM.render(<App />, document.getElementById('root'));

干杯!

这对我有用:

 var nodes = new vis.DataSet([
        {id: 1, label: 'Node 1'},
        {id: 2, label: 'Node 2'},
        {id: 3, label: 'Node 3'},
        {id: 4, label: 'Node 4'},
        {id: 5, label: 'Node 5'}
    ]);

    // create an array with edges
    var edges = new vis.DataSet([
        {from: 1, to: 3},
        {from: 1, to: 2},
        {from: 2, to: 4},
        {from: 2, to: 5}
    ]);

var data = {
        nodes: nodes,
        edges: edges
    };
    var options = {};

    // initialize your network!


var VisNetwork = React.createClass({

    componentDidMount(){
            var network = new vis.Network(this.refs.myRef, data, options);
  },

  render: function() {
    return <div ref="myRef"></div>;
  }
});

ReactDOM.render(
  <VisNetwork />,
  document.getElementById('container')
);

从 React 16.3 开始，推荐使用React.createRef Docs

用 16.3 风格更新@Gino 的答案。

import { DataSet, Network } from 'vis';
import React, { Component, createRef } from "react";

const nodes = new DataSet([
  { id: 1, label: 'Node 1' },
  { id: 2, label: 'Node 2' },
  { id: 3, label: 'Node 3' },
  { id: 4, label: 'Node 4' },
  { id: 5, label: 'Node 5' }
]);

// create an array with edges
const edges = new DataSet([
  { from: 1, to: 3 },
  { from: 1, to: 2 },
  { from: 2, to: 4 },
  { from: 2, to: 5 }
]);

const data = {
  nodes: nodes,
  edges: edges
};
const options = {};

// initialize your network!


class VisNetwork extends Component {

  constructor() {
    super();
    this.network = {};
    this.appRef = createRef();
  }

  componentDidMount() {
    this.network = new Network(this.appRef.current, data, options);
  }

  render() {
    return (
      <div ref={this.appRef} />
    );
  }
}

这是一个使用函数式组件和 React 钩子的现代示例。

package.json

{
  "dependencies": {
    "react": "16.13.0",
    "react-dom": "16.13.0",
    "vis-network": "7.4.0"
  }
}

VisNetwork.js

import React, { useEffect, useRef } from 'react';
import { DataSet, Network} from 'vis-network/standalone/esm/vis-network';

const VisNetwork = () => {
  // A reference to the div rendered by this component
  const domNode = useRef(null);

  // A reference to the vis network instance
  const network = useRef(null);

  // An array of nodes
  const nodes = new DataSet([
    { id: 1, label: 'Node 1' },
    { id: 2, label: 'Node 2' },
    { id: 3, label: 'Node 3' },
    { id: 4, label: 'Node 4' },
    { id: 5, label: 'Node 5' }
  ]);

  // An array of edges
  const edges = new DataSet([
    { from: 1, to: 3 },
    { from: 1, to: 2 },
    { from: 2, to: 4 },
    { from: 2, to: 5 }
  ]);

  const data = {
    nodes,
    edges
  };

  const options = {};

  useEffect(
    () => {
      network.current = new Network(domNode.current, data, options);
    },
    [domNode, network, data, options]
  );

  return (
    <div ref = { domNode } />
  );
};

export default VisNetwork;
