How to use Vue and Element Plus to implement data export and print functions

In recent years, with the rapid development of front-end development, more and more web applications need to provide data export and print functions to meet the needs of Users’ diverse usage needs for data. As a popular JavaScript framework, Vue can easily implement data export and printing functions when used with the Element Plus component library. This article will introduce a data export and printing implementation method based on Vue and Element Plus, with code examples.

1. Implementation of data export function

The data export function refers to exporting the data in the front-end page into an Excel file for users to download and use locally. Vue and Element Plus provide related components and methods to help us achieve this function.

First, introduce the two core components of Element Plus into the Vue component: Table and Button. Table is used to display data, and Button is used to trigger export operations.

<template>
  <div>
    <el-button type="primary" @click="handleDownload">導出</el-button>
    <el-table :data="tableData">
      <!-- 表格列的具體定義 -->
      ...
    </el-table>
  </div>
</template>

<script>
import { ref } from 'vue'
import { ElButton, ElTable } from 'element-plus'
import { exportToExcel } from 'your-export-utils'

export default {
  components: {
    ElButton,
    ElTable
  },
  setup() {
    const tableData = ref([]) // 表格數(shù)據(jù)

    // 處理導出按鈕點擊事件
    const handleDownload = () => {
      exportToExcel(tableData.value, '文件名') // 調(diào)用導出函數(shù)，傳入數(shù)據(jù)和文件名
    }

    return {
      tableData,
      handleDownload
    }
  }
}
</script>

Among them, exportToExcel is a custom export function that needs to be implemented according to specific business needs. The implementation of the export function can use libraries such as xlsx to convert data into Excel files and provide download links. The specific implementation of exportToExcel is not the focus of this article. Readers can conduct research and practice based on the actual situation.

2. Implementation of data printing function

The data printing function refers to outputting the data in the front-end page in paper form. Vue and Element Plus can easily implement this function, allowing users to print data conveniently.

First, introduce the two core components of Element Plus into the Vue component: Table and Button. Table is used to display data, and Button is used to trigger printing operations.

<template>
  <div>
    <el-button type="primary" @click="handlePrint">打印</el-button>
    <el-table :data="tableData">
      <!-- 表格列的具體定義 -->
      ...
    </el-table>
  </div>
</template>

<script>
import { ref } from 'vue'
import { ElButton, ElTable } from 'element-plus'

export default {
  components: {
    ElButton,
    ElTable
  },
  setup() {
    const tableData = ref([]) // 表格數(shù)據(jù)

    // 處理打印按鈕點擊事件
    const handlePrint = () => {
      window.print() // 調(diào)用瀏覽器的打印功能
    }

    return {
      tableData,
      handlePrint
    }
  }
}
</script>

In the above code, we simply call the browser’s print function. At this time, the data on the page will be presented in table form and the browser's print operation will be automatically triggered. Readers can further beautify and optimize the printing style of data according to actual needs.

Summary:

This article introduces how to use Vue and Element Plus to implement data export and printing functions. By calling relevant components and methods, we can easily implement the data export function and data printing function. In the code example, we use two Element Plus components, Table and Button, and implement data export and printing operations through customized export functions and the browser's print function. I hope this article will be helpful to readers and guide you to further learn and practice the use of Vue and Element Plus.
