本文主要是介绍vue3中使用antv-X6实现关系图,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!
先看效果图:
1、安装 npm install@antv/x6 --save
这里使用的X6中自定义节点的方式实现的,项目目录如下,hooks里面存放一些函数和变量
nodes里面是自定义节点的页面,最外围的index.vue就是主渲染页面
2、testSh/index.vue
注意:
(1)代码如下,里面有个useMouse()函数,追踪鼠标位置,这个需要项目中安装vueuse,可以查看下面文章去自行安装,Vueuse中文文档详解_笔记大全_设计学院

4、hooks/comGraph.ts
存放一些静态变量
// 线的样式
export const edgeStyle = {attrs: {line: {stroke: "rgb(26, 97, 211)", //线条颜色strokeWidth: 1, //线条粗细targetMarker: null, //不设置箭头},},allowNode: true,snap: true,allowLoop: false,router: {// 路由类型 normal orth(正交路由)name: "manhattan", //智能正交,自动避开障碍args: {step: 70,padding: 50,offset: 24,},},allowMulti: true,connector: {name: "jumpover",args: {radius: 14,},},
};
// 设置线
export const setEdge = (source: string, target: string, showLable: boolean) => {return {shape: "double-edge",source: { cell: source },target: { cell: target },label: showLable ? [] : "",...edgeStyle,};
};
//线和节点数据
export const Data = {"tables": [{"name": "产品线","path": "productlines","fields": [{"code": "productLine","name": "主键",},{"code": "textDescription","name": "纯文本描述",}]},{"name": "客户表","path": "customers","fields": [{"code": "phone","name": "联系电话",},{"code": "addressLine1","name": "联系地址1",},{"code": "addressLine2","name": "联系地址2",},{"code": "city","name": "所在城市",},{"code": "state","name": "州",},]},{"name": "订单表","path": "orders","fields": [{"code": "orderDate","name": "下单日期",},{"code": "requiredDate","name": "需用日期",},{"code": "shippedDate","name": "发货日期",},{"code": "status","name": "状态",},]},{"name": "订单明细表","path": "orderdetails","fields": [{"code": "orderNumber","name": "订单编号",},{"code": "productCode","name": "产品编号",},]},{"name": "员工表","path": "employees","fields": [{"code": "employeeNumber","name": "员工编号",},{"code": "lastName","name": "姓",},{"code": "firstName","name": "名",},{"code": "extension","name": "分机号",},{"code": "email","name": "电子邮件",},]},{"name": "付款","path": "payments","fields": [{"code": "customerNumber","name": "客户编号",},{"code": "checkNumber","name": "检验数",},{"code": "paymentDate","name": "付款日",},{"code": "amount","name": "金额",}]},{"name": "产品","path": "products","fields": [{"code": "productCode","name": "产品编码",},{"code": "productName","name": "产品名称",},{"code": "productLine","name": "产品线",},{"code": "productScale","name": "生产规模",}]}],"links": [{"sourcePath": "orders","targetPath": "customers",},{"sourcePath": "payments","targetPath": "customers",},{"sourcePath": "customers","targetPath": "employees",},{"sourcePath": "orderdetails","targetPath": "products",},{"sourcePath": "orderdetails","targetPath": "orders",},{"sourcePath": "products","targetPath": "productlines",}]
