How to use Vue and Element Plus to implement message notifications and pop-up prompts

Introduction:
In web application development, message notifications and pop-up prompts are one of the very important functions. As a popular front-end framework, Vue, combined with Element Plus, an excellent UI library, can easily implement various pop-up prompts and message notification functions. This article will introduce how to use the Element Plus component library in a Vue project to implement message notification and pop-up prompt functions, and attach relevant code examples.

1. Install and configure Element Plus
First, we need to install and configure the Element Plus component library in the Vue project. Open the terminal, enter the root directory of the Vue project, and execute the following command to install:

npm install element-plus --save

After the installation is complete, add the following code to the main.js file of the project:

import { createApp } from 'vue'
import ElementPlus from 'element-plus'
import 'element-plus/lib/theme-chalk/index.css'

const app = createApp(App)
app.use(ElementPlus)
app.mount('#app')

2. Use the message notification component
Element Plus provides the ElNotification component, which can be used to display various message notifications. The following is a simple example showing how to use the ElNotification component to display a success prompt:

<template>
  <div>
    <el-button @click="showSuccess">显示成功提示</el-button>
  </div>
</template>

<script>
export default {
  methods: {
    showSuccess() {
      this.$notify({
        title: '成功',
        message: '操作成功',
        type: 'success'
      })
    }
  }
}
</script>

In the above code, we call the ElNotification component through the this.$notify method and pass in the relevant Configuration parameters. The title parameter is used to set the title of the prompt, message is used to set the content of the prompt, type is used to set the type of prompt, here we set it to success indicates success prompt. Once the button is clicked, a success message is displayed.

In addition to success prompts, the ElNotification component also supports other types of prompts, such as warning, info, error, etc. By setting different type parameters, different styles of prompts can be achieved.

3. Use the pop-up window component
Element Plus provides the ElMessageBox component for displaying various pop-up window prompts. The following is an example showing how to use the ElMessageBox component to display a confirmation dialog box:

<template>
  <div>
    <el-button @click="showConfirm">显示确认对话框</el-button>
  </div>
</template>

<script>
export default {
  methods: {
    showConfirm() {
      this.$confirm('确定删除吗？', '提示', {
        confirmButtonText: '确定',
        cancelButtonText: '取消',
        type: 'warning'
      }).then(() => {
        // 确认删除操作
      }).catch(() => {
        // 取消删除操作
      })
    }
  }
}
</script>

In the above code, the ElMessageBox component is called through the this.$confirm method and the relevant configuration parameters are passed in. The first parameter is used to set the prompt content of the dialog box, and the second parameter is used to set the title of the dialog box. The OK button and Cancel button can be set through the confirmButtonText and cancelButtonText parameters. Text, type parameters are used to set the style of the dialog box.

After clicking the button, a confirmation dialog box will be displayed. Pressing the OK button will execute the logic in the then function; pressing the Cancel button or closing the dialog box will execute the logic in the catch function.

Summary:
Through Vue and Element Plus, we can easily implement message notification and pop-up prompt functions. In this article, we describe how to install and configure the Element Plus component library and provide code examples for using the ElNotification component and the ElMessageBox component. In actual projects, we can configure and customize it according to needs to meet different business needs. I hope this article can help you implement message notification and pop-up prompt functions in your Vue project.
