Tooltip 插件用于在用户将鼠标悬停或点击图中的元素时,显示额外的信息。它可以帮助用户更好地理解图中的数据,提高交互体验。
最简单的 Tooltip 插件配置:
const graph = new Graph({// 其他配置...plugins: [{type: 'tooltip',},],});
属性 | 描述 | 类型 | 默认值 | 必选 |
---|---|---|---|---|
type | 插件类型 | string | tooltip | ✓ |
key | 标识符 | string | - | |
position | 气泡框位置 | top | bottom | left | right | top-left | top-right | bottom-left | bottom-right | top-right | |
enable | 插件是否启用 | boolean | ((event: IElementEvent, items: NodeData | EdgeData | ComboData[]) => boolean) | true | |
getContent | 自定义内容 | (event: IElementEvent, items: NodeData | EdgeData | ComboData[]) => Promise<HTMLElement | string> | - | |
onOpenChange | 显示隐藏的回调 | (open: boolean) => void | - | |
trigger | 触发行为 | hover | click | hover | |
container | tooltip自定义渲染的容器 | string | HTMLElement | - | |
offset | 偏移距离 | [number,number] | [10,10] | |
enterable | 指针是否可以进入 | boolean | false | |
title | 标题 | string | - | |
style | 样式对象 | Record<string,any> | {'.tooltip': { visibility: 'hidden'}} |
控制插件是否启用,支持传入函数动态调整启用逻辑。
示例:只对节点启用 Tooltip
import { Graph } from '@antv/g6';const data = {nodes: [{ id: 'node1', style: { x: 100, y: 100 }, data: { name: '服务器节点' } },{ id: 'node2', style: { x: 200, y: 100 }, data: { name: '数据库节点' } },],edges: [{ source: 'node1', target: 'node2', data: { type: '连接线' } }],};const graph = new Graph({container: 'container',width: 400,height: 200,data,plugins: [{type: 'tooltip',// 只对节点启用,边不显示tooltipenable: (e) => e.targetType === 'node',getContent: (e, items) => {return `<div>节点: ${items[0].data.name}</div>`;},},],});graph.render();
自定义渲染 Tooltip 内容,支持返回 HTMLElement 或 string。
示例:动态渲染自定义 HTML 内容
import { Graph } from '@antv/g6';const data = {nodes: [{id: 'node1',style: { x: 100, y: 100 },data: { name: '服务器A', type: '应用服务器', status: '运行中', cpu: '45%', memory: '2.1GB' },},{id: 'node2',style: { x: 250, y: 100 },data: { name: '数据库B', type: 'MySQL数据库', status: '正常', connections: 23, size: '500MB' },},],edges: [{ source: 'node1', target: 'node2', data: { bandwidth: '1Gbps', latency: '5ms' } }],};const graph = new Graph({container: 'container',width: 400,height: 200,data,plugins: [{type: 'tooltip',getContent: (e, items) => {const item = items[0];if (e.targetType === 'node') {return `<div><h4 style="margin: 0 0 8px 0; color: #333; border-bottom: 1px solid #eee; padding-bottom: 4px;">${item.data.name}</h4><div style="margin: 4px 0; color: #666;"><strong>类型:</strong> ${item.data.type}</div><div style="margin: 4px 0; color: #666;"><strong>状态:</strong><span style="color: ${item.data.status === '运行中' || item.data.status === '正常' ? '#52c41a' : '#ff4d4f'}">${item.data.status}</span></div>${item.data.cpu ? `<div style="margin: 4px 0; color: #666;"><strong>CPU:</strong> ${item.data.cpu}</div>` : ''}${item.data.memory ? `<div style="margin: 4px 0; color: #666;"><strong>内存:</strong> ${item.data.memory}</div>` : ''}${item.data.connections ? `<div style="margin: 4px 0; color: #666;"><strong>连接数:</strong> ${item.data.connections}</div>` : ''}${item.data.size ? `<div style="margin: 4px 0; color: #666;"><strong>大小:</strong> ${item.data.size}</div>` : ''}</div>`;} else if (e.targetType === 'edge') {return `<div><h4 style="margin: 0 0 8px 0; color: #333;">连接信息</h4><div style="margin: 4px 0; color: #666;"><strong>带宽:</strong> ${item.data.bandwidth}</div><div style="margin: 4px 0; color: #666;"><strong>延迟:</strong> ${item.data.latency}</div></div>`;}return '暂无信息';},},],});graph.render();
控制 Tooltip 的触发行为。
可选值:
hover
:鼠标移入元素时触发(默认)click
:鼠标点击元素时触发示例:点击触发 Tooltip
import { Graph } from '@antv/g6';const data = {nodes: [{ id: 'node1', style: { x: 100, y: 100 }, data: { name: '点击我' } },{ id: 'node2', style: { x: 200, y: 100 }, data: { name: '也点击我' } },],edges: [{ source: 'node1', target: 'node2' }],};const graph = new Graph({container: 'container',width: 350,height: 200,data,node: {style: {labelText: (d) => d.data.name,},},plugins: [{type: 'tooltip',trigger: 'click',getContent: (e, items) => {return `<div><div style="color: #0369a1; font-weight: bold; margin-bottom: 4px;">点击触发 🖱️</div><div style="color: #0c4a6e;">元素ID: ${items[0].id}<br/>名称: ${items[0].data?.name || '未命名'}</div></div>`;},},],});graph.render();
控制 Tooltip 相对于鼠标位置的显示位置。
可选值:
top
: 顶部bottom
: 底部left
: 左侧right
: 右侧top-left
: 顶部靠左top-right
: 顶部靠右(默认)bottom-left
: 底部靠左bottom-right
: 底部靠右示例:不同位置的 Tooltip
import { Graph } from '@antv/g6';const data = {nodes: [{ id: 'node1', style: { x: 100, y: 100 }, data: { label: 'TOP' } },{ id: 'node2', style: { x: 250, y: 100 }, data: { label: 'BOTTOM' } },{ id: 'node3', style: { x: 100, y: 250 }, data: { label: 'LEFT' } },{ id: 'node4', style: { x: 250, y: 250 }, data: { label: 'RIGHT' } },],};const graph = new Graph({container: 'container',width: 800,height: 400,data,node: { style: { labelText: (d) => d.data.label } },plugins: [{key: 'tooltip-top',type: 'tooltip',position: 'top',enable: (e, items) => items[0].id === 'node1',getContent: () => `顶部显示 ⬆️`,style: {'.tooltip': {background: ' #fff2e8',border: '1px solid #ffa940',borderRadius: 4,},},},{key: 'tooltip-bottom',type: 'tooltip',position: 'bottom',enable: (e, items) => items[0].id === 'node2',getContent: () => `底部显示 ⬇️`,style: {'.tooltip': {background: '#f6ffed',border: '1px solid #73d13d',borderRadius: 4,},},},{key: 'tooltip-left',type: 'tooltip',position: 'left',enable: (e, items) => items[0].id === 'node3',getContent: () => `左侧显示 ⬅️`,style: {'.tooltip': {background: '#fff1f0',border: '1px solid #ff7875',borderRadius: 4,},},},{key: 'tooltip-right',type: 'tooltip',position: 'right',enable: (e, items) => items[0].id === 'node4',getContent: () => `右侧显示 ➡️`,style: {'.tooltip': {background: '#f0f5ff',border: '1px solid #597ef7',borderRadius: 4,},},},],});graph.render();
设置 Tooltip 显示位置的偏移量,以鼠标位置为基点。
import { Graph } from '@antv/g6';const data = {nodes: [{ id: 'node1', style: { x: 100, y: 100 }, data: { label: '默认偏移' } },{ id: 'node2', style: { x: 250, y: 100 }, data: { label: '自定义偏移' } },],};const graph = new Graph({container: 'container',width: 800,height: 200,data,plugins: [{key: 'tooltip-default',type: 'tooltip',enable: (e, items) => items[0].id === 'node1',getContent: () => `默认偏移 [10,10]`,},{key: 'tooltip-custom',type: 'tooltip',offset: [30, -10], // 向右偏移30px,向上偏移10pxenable: (e, items) => items[0].id === 'node2',getContent: () => `自定义偏移 [30,-10]`,},],});graph.render();
控制鼠标指针是否可以进入气泡框,常用于需要在 Tooltip 内进行交互的场景。
import { Graph } from '@antv/g6';const data = {nodes: [{ id: 'node1', style: { x: 100, y: 100 }, data: { name: '用户A', email: 'usera@example.com' } },{ id: 'node2', style: { x: 250, y: 100 }, data: { name: '用户B', email: 'userb@example.com' } },],};const graph = new Graph({container: 'container',width: 400,height: 200,data,plugins: [{type: 'tooltip',enterable: true,position: 'right',getContent: (e, items) => {const item = items[0];return `<div><h4 style="margin: 0 0 12px 0; color: #333;">用户操作</h4><div style="margin-bottom: 8px; color: #666;"><strong>姓名:</strong> ${item.data.name}</div><div style="margin-bottom: 12px; color: #666;"><strong>邮箱:</strong> ${item.data.email}</div><div style="display: flex; gap: 8px;"><button onclick="alert('发送消息给 ${item.data.name}')"style="padding: 4px 12px; background: #1890ff; color: white; border: none; border-radius: 4px; cursor: pointer; font-size: 12px;">发消息</button><button onclick="alert('查看 ${item.data.name} 的详情')"style="padding: 4px 12px; background: #52c41a; color: white; border: none; border-radius: 4px; cursor: pointer; font-size: 12px;">详情</button></div></div>`;},style: {'.tooltip': {background: '#fff',borderRadius: '8px',boxShadow: '0 4px 20px rgba(0,0,0,0.15)',minWidth: '200px',},},},],});graph.render();
自定义 Tooltip 的样式。
import { Graph } from '@antv/g6';const data = {nodes: [{ id: 'node1', style: { x: 100, y: 100 }, data: { theme: 'dark', name: '深色主题' } },{ id: 'node2', style: { x: 250, y: 100 }, data: { theme: 'light', name: '浅色主题' } },],};const graph = new Graph({container: 'container',width: 400,height: 200,data,plugins: [{key: 'tooltip-dark',type: 'tooltip',enable: (e, items) => items[0].data.theme === 'dark',style: {'.tooltip': {background: '#1f1f1f',color: '#fff',border: '1px solid #333',borderRadius: '8px',fontSize: '14px',fontFamily: 'Arial, sans-serif',boxShadow: '0 4px 20px rgba(0,0,0,0.3)',},},getContent: (e, items) => {return `<div>🌙 ${items[0].data.name}</div>`;},},{key: 'tooltip-light',type: 'tooltip',enable: (e, items) => items[0].data.theme === 'light',style: {'.tooltip': {background: '#ffffff',color: '#333',border: '1px solid #d9d9d9',borderRadius: '8px',fontSize: '14px',fontFamily: 'Arial, sans-serif',boxShadow: '0 2px 8px rgba(0,0,0,0.15)',},},getContent: (e, items) => {return `<div>☀️ ${items[0].data.name}</div>`;},},],});graph.render();
