官方文档是react实现的，但项目里使用的vue3+elementPlus，经过研究后通过以下方式实现：
- 在根目录的index.html里添加右键菜单的元素
<body>
<!-- 模型的自定义工具容器 -->
+ <div id="graph-dropdown"></div>
<div id="app"><div id="loader-wrapper"><div id="loader"></div><div class="loader-section section-left"></div><div class="loader-section section-right"></div><div class="load_title">正在加载系统资源，请耐心等待</div></div>
</div>
还有该元素的css属性
#graph-dropdown {position: absolute;z-index: 2;background-color: #fff;top: 0;left: 0;
}
- 定义工具类
contextMenuTool.jsx
import { ElDropdown, ElButton } from 'element-plus'
import { ToolsView } from '@antv/x6'
import { createApp } from 'vue'// ContextMenu挂载的Vue实例
let app = null;
let timer = null; // timerclass ContextMenuTool extends ToolsView.ToolItem {toggleContextMenu(visible, pos) {if (app) {// 清空上次内容app.unmount();document.getElementById('graph-dropdown').innerHTML = '';app = null}document.removeEventListener('mousedown', this.onMouseDown)if (visible && pos) {app = createApp(<ElDropdowntrigger={['contextmenu']}>{{default: () => {// menu是在createEdge传入的argsif (Array.isArray(this.options.menu)) {return <div style="padding: 10px;">{this.options.menu.map(item => {return <ElButton style="margin-left: 0;display:block;border: 0;" icon={item.icon} onClick={item.onClick}>{ item.label }</ElButton>})}</div>}}}}</ElDropdown>)// 减去本身元素的宽高document.getElementById('graph-dropdown').style = `left: ${pos.x - 40}px;top: ${pos.y - 40}px;`app.mount('#graph-dropdown')document.addEventListener('mousedown', this.onMouseDown)}}onMouseDown = () => {timer = window.setTimeout(() => {this.toggleContextMenu(false)},200)}onContextMenu({ e }) {debuggerif (timer) {clearTimeout(timer)timer = 0}this.toggleContextMenu(true, { x: e.pageX, y: e.pageY })}delegateEvents() {this.cellView.on('cell:contextmenu', this.onContextMenu, this)return super.delegateEvents()}onRemove() {this.cellView.off('cell:contextmenu', this.onContextMenu, this)}
}ContextMenuTool.config({tagName: 'div',isSVGElement: false
})export {ContextMenuTool
}- vue中使用
// 画布中自定义右键菜单工具的类
import { ContextMenuTool } from "../components/contextMenuTool"// 在初始化画布之前注册自定义工具
Graph.registerEdgeTool('contextmenu', ContextMenuTool, true)graph = new Graph({container: document.getElementById('container'),...GRAPH_CONFIG,connecting: { // 连线规则...CONNECTING_CONFIG,createEdge() {return new Shape.Edge({tools: [{name: 'contextmenu',args: {menu: [{ label: '删除连接线', onClick: () => console.log('删除'), icon: Delete },{ label: '对应关系', onClick: () => console.log('查看'), icon: Connection }]}}]})}}});
若是使用的其他ui框架，变更下拉菜单组件即可。
