Uniapp is a cross-platform application development framework based on Vue.js, which can build applications running on multiple platforms at the same time, such as WeChat applets, Apps, H5, etc. During the development process, we often need to implement the functions of announcement notifications and message reminders in order to send important information to users in a timely manner. The following describes how to use Uniapp to implement these two functions and provides code examples.
1. Implement the announcement and notification function
The announcement and notification function is usually used to publish some important announcements or notification information to ensure that users can obtain this information in a timely manner. Below is a simple example that demonstrates how to implement the announcement notification function in Uniapp.
Create an announcement list page
On the page, display the announcement list. Click an announcement to enter the announcement details page.
<template> <view> <view v-for="notice in notices" @click="goToNoticeDetail(notice)"> {{notice.title}} </view> </view> </template> <script> export default { data() { return { notices: [ { title: '公告1', content: '公告内容1' }, { title: '公告2', content: '公告内容2' }, { title: '公告3', content: '公告内容3' }, ] } }, methods: { goToNoticeDetail(notice) { uni.navigateTo({ url: `/pages/noticeDetail/noticeDetail?title=${notice.title}&content=${notice.content}` }) } }, } </script>
Create announcement details page
Display the details of the announcement, such as title and content, on this page.
<template> <view> <view> {{title}} </view> <view> {{content}} </view> </view> </template> <script> export default { data() { return { title: '', content: '', } }, onLoad(options) { this.title = options.title || '' this.content = options.content || '' } } </script>
Through the above code, we have implemented a simple announcement notification function. Users can see all announcements on the announcement list page. After clicking on an announcement, they will jump to the announcement details page to view the details of the announcement.
2. Implement the message reminder function
The message reminder function is usually used to send some instant messages to users, such as system notifications, new developments, etc. Below is a simple example that demonstrates how to implement the message reminder function in Uniapp.
Configure message push service
Configure in the main.js file of the project. The sample code is as follows:
import Vue from 'vue' import App from './App' Vue.config.productionTip = false App.mpType = 'app' // 配置消息推送服务 uni.request({ url: 'https://your-push-server.com/config', success(res) { uni.setPushProvider({ provider: 'your-push-provider', ...res.data }) } }) const app = new Vue({ ...App }) app.$mount()
Receive and display push messages
Add code to the page that needs to be received to receive and display messages. The sample code is as follows:
<template> <view> <view v-for="message in messages"> {{message.title}} </view> </view> </template> <script> export default { data() { return { messages: [], } }, onLoad() { uni.onPushMessage((res) => { const message = JSON.parse(res.content) this.messages.push(message) }) } } </script>
Through the above code, when our push service has new messages, Uniapp will automatically receive and display the title of the new message in the message list. We can further process these messages on the page, such as clicking on a message to jump to the corresponding page.
Summary:
Through the above code examples, we demonstrate how to implement announcement notification and message reminder functions in Uniapp. The announcement notification function ensures that users can obtain important information in a timely manner by displaying the announcement list and announcement details. The message reminder function can send instant notifications to users by configuring the message push service and receiving push messages. You can develop more complex functions based on these sample codes based on actual needs.
