vis插件实现网络拓扑图
安装引入vis
1.npm安装vis
npm install vis
2.引入vis
import { DataSet, Network } from 'vis';
vis使用示例
methods:{
globalTrace () {
// create an array with nodes
var nodes = new DataSet([
{id: 1, label: 'Node 1'},
{id: 2, label: 'Node 2'},
{id: 3, label: 'Node 3'},
{id: 4, label: 'Node 4'},
{id: 5, label: 'Node 5'}
]);
// create an array with edges
var edges = new DataSet([
{from: 1, to: 3},
{from: 1, to: 2},
{from: 2, to: 4},
{from: 2, to: 5}
]);
// create a network
var container = document.querySelector('#global_trace_content');
// provide the data in the vis format
var data = {
nodes: nodes,
edges: edges
};
var options = {
//节点样式
nodes: {
shape: "box",//设置节点node样式为矩形
fixed:true,//节点node固定不可移动
font: {
color: "white", //字体的颜色
size: 30 //显示字体大小
},
scaling: {
min: 16,
max: 32 //缩放效果比例
},
},
//连接线的样式

color: "rgb(97, 168, 224)",
highlight: "rgb(97, 168, 224)",
hover: "green",
inherit: "from",
opacity: 1.0
},
font: {
align: "top",//连接线文字位置
},
smooth: true, //是否显示方向箭头
arrows: {to : true },//箭头指向from节点
},
layout: {
//以分层方式定位节点
hierarchical: {
direction: "LR",//分层排序方向

},
},

navigationButtons: true,
// hover: true, //鼠标移过后加粗该节点和连接线
selectConnectedEdges: false, //选择节点后是否显示连接线
},
};
// initialize your network!
this.network = new Network(container, data, options);
this.network.on("click",e=> this.showDetail(e));//单击事件
this.network.on("doubleClick",e=> this.enterService(e))//双击事件
},
},

vis.js网络拓扑图点击折叠节点和展开节点
首先看一下效果图
1.数据中要添加的属性如下图所示：
2.数据中添加入上图属性后，添加点击事件即可，代码如下：
//todo 双击时折叠和展开
network.on("doubleClick", function(params) {//双击事件
if (params.nodes.length != 0) {//确定为节点双击事件
var click_node_id = params.nodes[0];
remove_all_sub_nodes(click_node_id);
}
});
//todo 删除下级所有节点
function remove_all_sub_nodes(node_id) {
var sub_nodes = get_directly_sub_nodes(node_id);
// console.log('sub_nodes',sub_nodes)
if (sub_nodes.length == 0) {//当前点击的为叶子节点
//判断是否有下级节点
// console.log('sub',allNodes[node_id - 1]['subids']);
if (typeof (allNodes[node_id - 1]['subids']) != 'undefined') {
$.each(allNodes[node_id - 1]['subids'], function(index, item) {
// console.log('allNodes[item - 1]',allNodes[item - 1])
nodes.add(allNodes[item - 1]);
edges.add({id: node_id + '_' + item, from: node_id, to: item});
});
} else {
alert('当前为叶子节点');
}
} else {
$.each(sub_nodes, function(index, item) {
var sub_sub_nodes = get_directly_sub_nodes(item);
if (sub_sub_nodes.length == 0) {
nodes.remove({id: item});
edges.remove({id: node_id + '_' + item});
} else {
remove_all_sub_nodes(item);
}
nodes.remove({id: item});
edges.remove({id: node_id + '_' + item});
});
}
}
//todo 获取某节点直属下级节点
function get_directly_sub_nodes(node_id) {
var return_nodes = [];
var connectedNodes = network.getConnectedNodes(node_id);//获取所有连接节点
$.each(connectedNodes, function(index, item) {
// console.log('allNodes',allNodes)
if (item != allNodes[node_id - 1]['pid']) {//当前节点的父节点 ，不操作
return_nodes.push(item);
}
});
return return_nodes;
}
