我正在开发一个 vue3 项目。
main.js;
import { createApp } from "vue"; import App from "./App.vue"; const app = createApp(App); import store from "./store"; app.use(store); import router from "./router/index"; app.use(router); ... //just try... app.mount("#app");
和我的 public/index.html
<!DOCTYPE html> <html lang=""> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width,initial-scale=1.0"> <link rel="icon" href="<%= BASE_URL %>favicon.ico"> <title><%= htmlWebpackPlugin.options.title %></title> <style> body { margin: 0px; } </style> </head> <body> <noscript> <strong>We're sorry but <%= htmlWebpackPlugin.options.title %> doesn't work properly without JavaScript enabled. Please enable it to continue.</strong> </noscript> <div id="app"></div> <!-- built files will be auto injected --> </body> </html>
还有我的 App.vue;
<template> <button @click=openNewPage()>create new page</button> <span>{{message}}</span> <router-view /> </template> <script> methods:{ openNewPage(){ var t = window.open('second.html','newMonitor','height=700,width=700,left=100,top=100,resizable=yes,scrollbars=yes,toolbar=yes,menubar=no,location=no,directories=no, status=yes'); } } </script>
我的商店对象;
export default createStore({ state: { message:'Hello' } });
和我的第二个.html;
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <meta http-equiv="Cache-Control" content="no-store" /> <meta http-equiv="Pragma" content="no-cache" /> <meta http-equiv="Expires" content="0" /> <title></title> </head> <body> <div id="appSecond" style="height:100%"> <template> <span>{{message}}</span> </template> </div> </body> </html>
当我使用 OpenNewPage 方法打开第二个屏幕时,我无法访问商店对象,并且我想要使用的组件不起作用。我正在尝试;
第二个.js
const app2 = createApp({ }); export { app2 };
和我的方法
import { app2 } from "../second.js"; openNewPage(){ var t = window.open('second.html','newMonitor','height=700,width=700,left=100,top=100,resizable=yes,scrollbars=yes,toolbar=yes,menubar=no,location=no,directories=no, status=yes'); if (t) { t.onload = function () { t.window.app = app2; app2.mount("#appSecond"); } } }
不知何故,我尝试在 secondary.html 中运行,但收到类似“[Vue warn]:无法安装应用程序:安装目标选择器”的警告。无论如何,代码不起作用。你能帮我吗?
openNewPage()
无法为新打开的页面运行脚本;只有新页面可以运行自己的脚本。当openNewPage()
尝试app2.mount()
时,它在自己的页面(而不是新页面)上运行该代码,从而导致您观察到的错误。解决方案
删除
openNewPage()
中的挂载代码,使其仅打开新页面:更新
second.html
以加载挂载应用的脚本,并删除<div id="appSecond">
中不必要的<template>
:在
second.js
中,添加安装您的应用程序的代码:
