最近一个项目，选中某些文本，然后右键进行一些操作，使用了vue-contextmenujs插件

1. 安装vue-contextmenujs

npm install vue-contextmenujs

2. mian.js中引用该组件

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

3. 页面中使用

 <div
        class="reader-docx"
        id="bodyContainer"
        style="justify-content: center; align-items: center;width:100%; height:100%;overflow:auto;"
        @contextmenu.prevent="rightClick($event)"
      >
      </div>

4.判断是否在该文本区域内

 rightClick(event) {
      console.log("点击了右键", event);
      this.chapterText = ""; // 先清空，chapterText 保存选中文本
      let sel = window.getSelection
        ? window.getSelection()
        : document.selection.createRange();
      let text = sel.toString();
      if (!text) {
        return false;
      }

      let divId = "bodyContainer";
      if (sel.getRangeAt) {

        var range = sel.getRangeAt(0);
        var ancestor = range.commonAncestorContainer;
        while (
          ancestor.id != divId && // Check id, class or otherwise
          ancestor.parentElement != null
        ) {
          ancestor = ancestor.parentElement;
        }

        if (ancestor.id == divId) {
          // Selection is within the editor.
          console.log("在div内");
          this.chapterText = window.getSelection().toString();
          this.$contextmenu({
            items: this.rightMenuData,
            event, // 鼠标事件信息
            customClass: "custom-class", // 自定义菜单 class
            zIndex: 3, // 菜单样式 z-index
            minWidth: 150, // 主菜单最小宽度
          });
        } else {
          console.log("不在div内");
          return false;
        }
      } else {
        //
        return false;
      }

      return false;
    },

5.菜单

 rightMenuData: [
        {
          label: "翻译",
          onClick: () => {
            this.handleTranslate();
          },
        },
           ....
        },
      ],
