How to use Vue and Element-UI to create a table that dynamically loads data
In modern web development, data tables are one of the common interface components. Vue.js is a very popular front-end framework nowadays, and Element-UI is a set of component libraries developed based on Vue.js, which provides a rich set of UI components for us to use. This article will introduce how to use Vue and Element-UI to create a table that can dynamically load data, and give corresponding code examples.
First, we need to install and introduce Vue and Element-UI.
// 安装Vue npm install vue // 引入Vue import Vue from 'vue' // 安装Element-UI npm install element-ui // 引入Element-UI import ElementUI from 'element-ui' import 'element-ui/lib/theme-chalk/index.css' // 使用Element-UI Vue.use(ElementUI)
Next, we need to create a Vue component to display the table.
<template> <div> <el-table :data="tableData" style="width: 100%"> <el-table-column prop="name" label="姓名"></el-table-column> <el-table-column prop="age" label="年龄"></el-table-column> <el-table-column prop="gender" label="性别"></el-table-column> </el-table> <el-pagination @size-change="handleSizeChange" @current-change="handleCurrentChange" :page-size="pageSize" :total="total" layout="prev, pager, next" style="margin-top: 20px" > </el-pagination> </div> </template> <script> export default { data() { return { tableData: [], currentPage: 1, pageSize: 10, total: 0 } }, created() { this.getData() }, methods: { getData() { // 发送请求获取数据 // 这里假设我们通过接口获取了一个包含多条数据的数组 // 假设接口返回的数据格式为:{ data: [], total: 0 } // data是一个数组,total是数据的总数 // 这里省略了具体的请求代码 const response = { data: [{ name: '张三', age: 18, gender: '男' }, { name: '李四', age: 20, gender: '女' }], total: 2 } this.tableData = response.data this.total = response.total }, handleSizeChange(size) { this.pageSize = size this.getData() }, handleCurrentChange(page) { this.currentPage = page this.getData() } } } </script>
In the above code, we use a el-table
component and a el-pagination
component to implement the table display and paging functions. tableData
is the data we obtain from the background interface. Call the getData
method in the created
life cycle hook to initialize the data. The handleSizeChange
and handleCurrentChange
methods are used to handle changes in the number of items displayed on each page and changes in the current page respectively. These two methods will be called when the user changes the number of items displayed on each page and when the user clicks on the page number. We re-call the getData
method here to obtain the corresponding data.
Finally, register the component in our entry file and start the Vue instance.
// 引入我们之前创建的组件 import DynamicTable from './DynamicTable.vue' // 创建Vue实例 new Vue({ el: '#app', components: { DynamicTable }, template: '<DynamicTable />' })
At this point, we have completed using Vue and Element-UI to create a table that dynamically loads data. We obtain data by calling the interface, control the amount of displayed data through paging, and display data tables and paging components to complete the entire function.
Summary:
This article introduces how to use Vue and Element-UI to create a table that dynamically loads data. We obtain data by calling the interface and control the amount of data displayed on each page through paging. We use el-table
components and el-pagination
components to display data tables and paging components. I hope this article will be helpful for you to learn Vue.js and Element-UI.

vue中props可以传递函数;vue中可以将字符串、数组、数字和对象作为props传递,props主要用于组件的传值,目的为了接收外面传过来的数据,语法为“export default {methods: {myFunction() {// ...}}};”。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
