在更改时更新vue文件 - Laravel Echo Pusher Notifications

Question

因此，在过去的几天里，我试图让这个模板在发生新事件时自动重新加载。这就是“通知”被修改后，通过添加新条目或已将通知标记为已读。

我使用下拉列表显示结果，现在我必须在发生事情时重新加载整个页面。对于现代应用来说，这不是很好。

PS。我对Vue完全不熟悉，因为这与laravel通知集成在一起。

这是我的.vue文件（你可以看到我自己尝试了一些没有成功的事情）

<template>

        <a href="#" class="dropdown-toggle icons" data-toggle="dropdown" role="button"

我的app.js.

Vue.component('notification', require('./components/Notification.vue'));

const app = new Vue({
    el: '#app',
    data: {
        notifications: ''
    },
    created() {
        axios.post('/notification/get').then(response => {
            this.notifications = response.data;
        });

        var userId = $('meta[name="userId"]').attr('content');
        Echo.private('App.User.' + userId).notification((notification) => {
            this.notifications.push(notification);
        });
    },
    computed: {
        notifications: function () {
            return this
        }
    }
});

提前感谢任何可以帮我解决此问题的人！

据我了解，您是否希望每次收到新的通知数据时都呈现多个通知？

在这种情况下，您可以使用props。如果您将props注入通知组件，则只要props更改，通知组件就会重新呈现

例

<notification :notifications='notifications'><notification>
