vue-tree-chart樹形組件的實現(含鼠標右擊事件)
基於 vue-tree-chart,生成項目效果預覽,包含鼠標右擊事件;
vue-tree-chart:https://github.com/tower1229/Vue-Tree-Chart
大傢可以直接安裝使用(具體事例可以查看官網)
但是個人建議最好是下載整個項目,封裝成組件調用
基於官網初始代碼,封裝組件:
<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) ?

新建一個組件,調用組件並增加鼠標右擊事件:
