Vue自定义右键菜单功能实现

本文中使用vue-contextmenujs来实现右键菜单组件功能。
效果如下图示：

该组件支持父子菜单，支持设置菜单图标、点击事件、可用状态、分割线，支持自定义样式等功能，具体使用参看如下步骤。

快速安装

npm安装

npm install vue-contextmenujs
或
yarn add vue-contextmenujs

CDN

<script src="https://unpkg.com/vue-contextmenujs/dist/contextmenu.umd.js">

使用

引入

CDN引入则不需要 Vue.use(Contextmenu)
测试中使用的是element-ui图标

import Contextmenu from "vue-contextmenujs"
Vue.use(Contextmenu);

// 在组件中调用显示菜单
// this.$contextmenu(options:MenuOptions);
// 鼠标点击或滚轮自动销毁, 也可手动销毁
// this.$contextmenu.destroy();

// 去除浏览器默认菜单
// event.preventDefault();

页面使用

<template>
  <div id="app" style="width:100vw;height:100vh" @contextmenu.prevent="onContextmenu"></div>
</template>

<script>
export default {
  methods: {
    onContextmenu(event) {
      this.$contextmenu({
        items: [
          {
            label: "返回(B)",
            onClick: () => {
              this.message = "返回(B)";
              console.log("返回(B)");
            }
          },
          { label: "前进(F)", disabled: true },
          { label: "重新加载(R)", divided: true, icon: "el-icon-refresh" },
          { label: "另存为(A)..." },
          { label: "打印(P)...", icon: "el-icon-printer" },
          { label: "投射(C)...", divided: true },
          {
            label: "使用网页翻译(T)",
            divided: true,
            minWidth: 0,
            children: [{ label: "翻译成简体中文" }, { label: "翻译成繁体中文" }]
          },
          {
            label: "截取网页(R)",
            minWidth: 0,
            children: [
              {
                label: "截取可视化区域",
                onClick: () => {
                  this.message = "截取可视化区域";
                  console.log("截取可视化区域");
                }
              },
              { label: "截取全屏" }
            ]
          },
          { label: "查看网页源代码(V)", icon: "el-icon-view" },
          { label: "检查(N)" }
        ],
        event,
        //x: event.clientX,
        //y: event.clientY,
        customClass: "custom-class",
        zIndex: 3,
        minWidth: 230
      });
      return false;
    }
  }
};
</script>

自定义样式

<style type="text/css">
  /* custom */
  .custom-class .menu_item__available:hover,
