vue-tree-chart 树形组件
aibujin 人气:0基于 vue-tree-chart，生成项目效果预览，包含鼠标右击事件；
vue-tree-chart：https://github.com/tower1229/Vue-Tree-Chart
大家可以直接安装使用(具体事例可以查看官网)
但是个人建议最好是下载整个项目,封装成组件调用
基于官网初始代码，封装组件：
<template>
<table v-if="treeData.name">
<tr>
<td :colspan="Array.isArray(treeData.children) ? treeData.children.length * 2 : 1"
:class="{parentLevel: Array.isArray(treeData.children) && treeData.children.length, extend: Array.isArray(treeData.children) && treeData.children.length && treeData.extend}"
>
<div :class="{node: true, hasMate: treeData.mate}">
<div class="person"
:class="Array.isArray(treeData.class) ? treeData.class : []"
>
<div class="avat">
<img :src="treeData.image_url" @contextmenu="$emit('click-node', treeData)"/>
</div>
<!-- <div class="name">{{treeData.name}}</div> -->
</div>
<div class="paeson_name">{{treeData.name}}</div>
<template v-if="Array.isArray(treeData.mate) && treeData.mate.length">
<div class="person" v-for="(mate, mateIndex) in treeData.mate" :key="treeData.name+mateIndex"
:class="Array.isArray(mate.class) ? mate.class : []"
@click="$emit('click-node', mate)"
>
<div class="avat">
<img :src="mate.image_url" />
</div>
<!-- <div class="name">{{mate.name}}</div> -->
</div>
<div class="paeson_name">{{treeData.name}}</div>
</template>
</div>
<div class="extend_handle" v-if="Array.isArray(treeData.children) && treeData.children.length" @click="toggleExtend(treeData)"></div>
</td>
</tr>
<tr v-if="Array.isArray(treeData.children) && treeData.children.length && treeData.extend">
<td v-for="(children, index) in treeData.children" :key="index" colspan="2" class="childLevel">
<TreeChart :json="children" @click-node="$emit('click-node', $event)"/>
</td>
</tr>
</table>
</template>
<script>
export default {

},
watch: {

let extendKey = function(jsonData){
jsonData.extend = (jsonData.extend===void 0 ? true: !!jsonData.extend);
if(Array.isArray(jsonData.children)){
jsonData.children.forEach(c => {
extendKey(c)
})
}
return jsonData;
}
if(Props){
this.treeData = extendKey(Props);

新建一个组件，调用组件并增加鼠标右击事件：
<template>
<div id="app">
<TreeChart :json="data" :class="{landscape: 1}" @click-node="clickNode" />
<div class="gl_prs_ctn" :style='[contextstyle]'>
<ul class='gl_prs_li'>
<li >添加</li>
<li >详情</li>
<li >编辑</li>
<li >删除</li>
</ul>
</div>
</div>
</template>
