How to implement notifications and message prompts in Vue?

Vue is a popular JavaScript framework for building modern web applications. In daily use, notifications and message prompts are indispensable functions. This article will introduce how to use Vue to implement notifications and message prompts.

1. Using Toast

Toast is a lightweight message prompt. Using Vue.js, you can easily add a Toast pop-up window on a web page. Here is an example of a basic Vue.js implementation: Various styles and themes can be added.

<div id="app">
  <button v-on:click="showNotification">显示通知</button>
  
  <div class="notification-overlay" v-show="notification" v-bind:class="{'notification-success':notificationType === 'success', 'notification-danger': notificationType === 'danger'}">
    {{ notificationMessage }}
  </div>
</div>

<script>
new Vue({
  el: '#app',
  data: {
    notification: false,
    notificationType: '',
    notificationMessage: ''
  },
  methods: {
    showNotification: function(type, message) {
      this.notificationType = type;
      this.notificationMessage = message;
      this.notification = true;
      setTimeout(function() {
        this.notification = false;
      }, 5000);
    }
  }
});
</script>

2. Using the Notification API

In addition, Vue provides convenient syntactic sugar when using the new Notification API. Using Vue.js, you can easily implement the notification system that comes with the browser without having to implement it yourself. Here is a basic example:

<div id="app">
  <button v-on:click="showNotification">显示通知</button>
</div>

<script>
new Vue({
  el: '#app',
  methods: {
    showNotification: function() {
      if (!("Notification" in window)) {
        alert("This browser does not support desktop notification");
      } else if (Notification.permission === "granted") {
        var notification = new Notification("通知标题", {
          body: "通知内容"
        });
      } else if (Notification.permission !== 'denied') {
        Notification.requestPermission(function(permission) {
          if (permission === "granted") {
              var notification = new Notification("通知标题", {
              body: "通知内容"
            });
          }
        });
      }
    }
  }
});
</script>

In this example, we use the Notification object to create a new notification. When a user clicks or checks in to a notification, it should be sent to your website for further processing.
