Question

我正在尝试使用Cordova构建混合应用。我正在使用VueJS进行路由和AJAX请求。

不幸的是，我无法捕获一些Cordova事件。甚至deviceReady事件都没有起作用。
这是我的档案：

require('./bootstrap');


var Vue = require('vue');
var VueRouter = require('vue-router');

Vue.use(VueRouter);

// Some components
Vue.component('test', require('./Vue/components/test.vue'));
Vue.component('mainnav', require('./Vue/partials/mainnav.vue'));

// Route-components
const Home = Vue.component('home', require('./Vue/pages/home.vue'));
const Login = Vue.component('login', require('./Vue/pages/auth/login.vue'));
const Register = Vue.component('register', require('./Vue/pages/auth/register.vue'));
const notFound = Vue.component('notFound', require('./Vue/pages/404.vue'));

// the routes
const routes = [
    { path: '', component: Home },
    { path: '/', component: Home },
    { path: '/login', component: Login },
    { path: '/register', component: Register },
    { path: '*', component: notFound }
];

const router = new VueRouter({
    mode: 'history',
    routes // short for routes: routes
});

const vueApp = new Vue({
    router,
    mounted: function(){
        //alert('VueJS is ready!');
        document.addEventListener('deviceReady', this.onDeviceReady, false);
    },
    methods: {
        onDeviceReady: function() {
            alert('Device is ready!');
        }
    }
}).$mount('#app');

也许我没有收到消息，因为在Vue准备好之前设备已准备就绪。但是我该如何处理呢？

我可以访问其他选项，例如来自Vue vibration-plugin的{{1}}和vue组件：

root-instance

任何想法，我如何在Vue中捕获设备就绪事件？

Answer 1

这可能是一个并发问题。尝试设置一些简单的信号量锁，只有当两者都打开时才触发一个函数（未经测试，但你明白了）：

let deviceReady = false
let vueMounted = false

const vueApp = new Vue({
  router,
  mounted: function(){
    vueMounted = true
    if (deviceReady) vueApp.everythingReady()
  },
  methods: {
    everythingReady: function() {
        alert('Vue is mounted and everything is ready')
    }
  }
}).$mount('#app')

document.addEventListener('deviceReady', () => {
  deviceReady = true
  if (vueMounted) vueApp.everythingReady()
}, false)

尝试：

vueApp = new Vue({ 
   //...
    methods: { 
          onDeviceReady: function() {
               alert('Device is ready!');
            } 
       } 
});

document.addEventListener(
      'deviceready', 
       vueApp.onDeviceReady
);

对于vue应用，您必须将<script src="cordova.js"></script>明确添加到public/index.html

<!DOCTYPE html>
<html lang="es">
  <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>My app</title>
  </head>
  <body>
    <script src="cordova.js"></script> <!-- dude, add this -->
    <div id="app"></div>
    <noscript>
      <strong
        >We're sorry but ia doesn't work properly without JavaScript enabled.
        Please enable it to continue.</strong
      >
    </noscript>
  </body>
</html>

Vue无法收听Cordova活动
