vue3 + antv x6 实现修改节点的大小和颜色

本文主要是介绍vue3 + antv x6 实现修改节点的大小和颜色，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

节点的属性：

内置节点：

修改节点属性的核心方法：

source.prop('size', { width: 120, height: 50 }) // 修改 x 坐标
source.attr('rect/fill', '#ccc') // 修改填充色，等价于 source.prop('attrs/rect/fill', '#ccc')

在React中的用法：

change = (command: string) => {const nodes = this.graph.getNodes()switch (command) {case 'prop':nodes.forEach((node) => {const width = 100 + Math.floor(Math.random() * 50)const height = 40 + Math.floor(Math.random() * 10)node.prop('size', { width, height })})breakcase 'attr':nodes.forEach((node) => {const color = Color.random().toHex()node.attr('body/fill', color)})breakdefault:break}
}

vue3实现修改节点大小

<script setup>
import {Graph} from '@antv/x6'
import {onMounted, ref} from "vue";
import {Snapline} from "@antv/x6-plugin-snapline";const data = {nodes: [{id: 'node1',shape: 'rect',x: 40,y: 40,width: 100,height: 40,label: 'hello',attrs: {// body 是选择器名称，选中的是 rect 元素body: {stroke: '#8f8f8f',strokeWidth: 1,fill: '#fff',rx: 6,ry: 6,},},},{id: 'node2',shape: 'rect',x: 160,y: 180,width: 100,height: 40,label: 'world',attrs: {body: {stroke: '#8f8f8f',strokeWidth: 1,fill: '#fff',rx: 6,ry: 6,},},},],// 边：连接节点edges: [{shape: 'edge',source: 'node1', // 开始节点target: 'node2', // 目标节点，会建立从开始节点到目标节点的连线label: 'x6',attrs: {// line 是选择器名称，选中的边的 path 元素line: {stroke: '#8f8f8f',strokeWidth: 1,},},},],
}const graph = ref() // 图对象
// 修改大小
const updateSize = () => {const nodes = graph.value.getNodes()nodes.forEach((node) => {const width = 100 + Math.floor(Math.random() * 50)const height = 40 + Math.floor(Math.random() * 10)node.prop('size', {width, height})})
}onMounted(() => {graph.value = new Graph({container: document.getElementById('container'),width: 800,height: 600,background: {color: '#F2F7FA',},})graph.value.fromJSON(data) // 渲染元素graph.value.centerContent() // 居中显示// 使用插件graph.value.use(// 自动对齐new Snapline({enabled: true,}),)// 数据导出console.log(graph.value.toJSON())
})
</script><template><div><div><button @click="updateSize">修改节点大小</button></div><div id="container"></div></div>
</template><style scoped></style>

vue3实现修改节点颜色

<script setup>
import {Color, Graph} from '@antv/x6'
import {onMounted, ref} from "vue";
import {Snapline} from "@antv/x6-plugin-snapline";const data = {nodes: [{id: 'node1',shape: 'rect',x: 40,y: 40,width: 100,height: 40,label: 'hello',attrs: {// body 是选择器名称，选中的是 rect 元素body: {stroke: '#8f8f8f',strokeWidth: 1,fill: '#fff',rx: 6,ry: 6,},},},{id: 'node2',shape: 'rect',x: 160,y: 180,width: 100,height: 40,label: 'world',attrs: {body: {stroke: '#8f8f8f',strokeWidth: 1,fill: '#fff',rx: 6,ry: 6,},},},],// 边：连接节点edges: [{shape: 'edge',source: 'node1', // 开始节点target: 'node2', // 目标节点，会建立从开始节点到目标节点的连线label: 'x6',attrs: {// line 是选择器名称，选中的边的 path 元素line: {stroke: '#8f8f8f',strokeWidth: 1,},},},],
}const graph = ref() // 图对象
// 修改大小
const updateSize = () => {const nodes = graph.value.getNodes()nodes.forEach((node) => {const width = 100 + Math.floor(Math.random() * 50)const height = 40 + Math.floor(Math.random() * 10)node.prop('size', {width, height})})
}
// 修改颜色
const updateColor = () => {const nodes = graph.value.getNodes()nodes.forEach((node) => {const color = Color.random().toHex()node.attr('body/fill', color)})
}
onMounted(() => {graph.value = new Graph({container: document.getElementById('container'),width: 800,height: 600,background: {color: '#F2F7FA',},})graph.value.fromJSON(data) // 渲染元素graph.value.centerContent() // 居中显示// 使用插件graph.value.use(// 自动对齐new Snapline({enabled: true,}),)// 数据导出console.log(graph.value.toJSON())
})
</script><template><div><div><button @click="updateSize">修改节点大小</button><button @click="updateColor">修改节点颜色</button></div><div id="container"></div></div>
</template><style scoped></style>
