主进程弹出菜单（主进程一般不弹出菜单）  渲染进程弹出菜单 index.html ``` ... <button onclick="openMenu()"></button> <script src="renderer/index.js"></script> ... ``` index.js ``` const {remote} = require("electron"); const menu,MenuItem=remote; funtion openMenu(){ const template=[ {lable:"第一个菜单项目"}, {lable:"点击测试",click:()=>{ console.log("点击成功"); }}, {role:"ondu"}, {lable:"旅游",type:"checkbox", checked:true}, {lable:"吃",type:"checkbox", checked:true}, {lable:"逛街",type:"checkbox", checked:false}, //new MenuItem({lable:"点击测试",click:()=>{ console.log("点击成功"); }}),//效果同上 //子菜单 { submenu:[ {label:"子菜单-1"}, {label:"子菜单-2"} {label:"子菜单-3"} ] } ]; const menu=Menu.buildFromTemplate(template); Menu.setApplicationMenu(); menu.popup(); } ```   >[danger]注意加上`Menu.setApplicationMenu();`后 点击弹出菜单窗口的横向菜单也会跟着改变，不想改变横向菜单可以将它注释掉
