主進程彈出菜單（主進程一般不彈出菜單）  渲染進程彈出菜單 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:"第一個菜單項目"}, {lable:"點擊測試",click:()=>{ console.log("點擊成功"); }}, {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:"點擊測試",click:()=>{ console.log("點擊成功"); }}),//效果同上 //子菜單 { submenu:[ {label:"子菜單-1"}, {label:"子菜單-2"} {label:"子菜單-3"} ] } ]; const menu=Menu.buildFromTemplate(template); Menu.setApplicationMenu(); menu.popup(); } ```   >[danger]注意加上`Menu.setApplicationMenu();`后 點擊彈出菜單窗口的橫向菜單也會跟著改變，不想改變橫向菜單可以將它注釋掉
