1、去GraphVis官网下载对应的js，新版和旧版的js有所不同，看自己需求引入旧版还是新版（GraphVis官方网址：http://www.graphvis.cn/）
- visgraph.min.js （基本配置js）
- visgraph-layout.min.js（配置布局js）
2、在需要的vue文件引入js文件
import VisGraph from '@/assets/js/GraphVis/old/visgraph.min.js' // 自己对应的js文件位置
import LayoutFactory from '@/assets/js/GraphVis/old/visgraph-layout.min.js' // 自己对应的js文件位置
export default { components: { VisGraph, LayoutFactory } }
3、加载画布和配置
配置(自己根据需求修改配置)：
config: {
// 节点配置
node: {
label: { // 标签配置
show: true, // 是否显示
color: '250,250,250', // 字体颜色
font: 'normal 14px Microsoft YaHei', // 字体大小及类型
textPosition: 'Middle_Center', // 字体位置
wrapText: true // 节点包裹文字(该属性为true时只对于字体位置为Middle_Center时有效)
},
shape: 'circle', // 节点形状 circle,rect,square,ellipse,triangle,star,polygon,text
// width: 60, // 节点宽度(只对于shape为rect时有效)
// height: 60, // 节点高度(只对于shape为rect时有效)
color: '62,160,250', // 节点颜色
borderColor: '62,160,250', // 节点边框颜色
borderWidth: 0, // 节点边框宽度
borderRadius: 0, // 节点圆角
lineDash: [0], // 节点边框线条类型 [0] 表示实线 [5,8] 表示虚线 borderWidth > 0有效
alpha: 1, // 节点透明度
size: 60, // 节点大小
selected: { // 节点选中后样式
borderColor: '136,198,255', // 选中时边框颜色
borderAlpha: 1, // 选中时的边框透明
borderWidth: 3, // 选中是的边框宽度
showShadow: true, // 是否展示阴影
shadowColor: '136,198,255' // 选中是的阴影颜色
}
},
// 线条配置
link: {
label: { // 标签配置
show: true, // 是否显示
color: '100,100,200', // 标签颜色
font: 'normal 10px Arial' // 标签文字大小及类型
},
lineType: 'direct', // 线条类型direct,curver,vlink,hlink,bezier,vbezier,hbezier
colorType: 'defined', // 连线颜色类型 source:继承source颜色,target:继承target颜色 both:用双边颜色，defined:自定义
color: '200,200,200', // 线条颜色
alpha: 1, // 连线透明度
lineWidth: 1, // 连线宽度
lineDash: [0], // 虚线间隔样式如：[5,8]
showArrow: true, // 显示箭头
selected: { // 选中时的样式设置
color: '20,250,50', // 选中时的颜色
alpha: 1, // 选中时的透明度
lineWidth: 4, // 选中线条宽度
showShadow: true, // 显示阴影
shadowColor: '50,250,50' // 阴影颜色
}
},
highLightNeiber: true, // 相邻节点高度标志
wheelZoom: 0.8 // 滚轮缩放开关，不使用时不设置[0,1]
}
加载画布：
this.visgraph = new VisGraph(
document.getElementById(this.canvasId),
this.canvasConfig
)
this.visgraph.clearAll()
this.visgraph.drawData(this.graphData)
4、拓展功能：
无限拓展子节点，双击节点触发（ondblClick）：
this.visgraph.restoreHightLight() // 取消高亮
const allNodes = this.visgraph.getVisibleData()
this.currentNode.push(node.id)
allNodes.nodes.forEach(item => {
if (this.currentNode.indexOf(item.id) === (-1)) {
this.visgraph.deleteNode(item)
}
})
const findNodeNum = Math.round(Math.random() * 50)
const increamData = this.buildIncreamData(node, findNodeNum)
this.visgraph.activeAddNodeLinks(increamData.nodes, increamData.links)
this.visgraph.translateToCenter()
