Element 介绍

Element：是饿了么团队研发的，一套为开发者、 设计师和产品经理准备的基于Vue 2.0的桌面端组件库。
组件：组成网页的部件，例如超链接、按钮、图片、表格、表单、分页条等等。
官网: https://element.eleme.cn/#/zh-CNListener

快速入门

• 安装 ElementUI 组件库（在当前工程的目录下），在命令执行指令：

npm install element-ui@2.15.3

• 引入 ElementUI 组件库（官网有）

main.js

import Vue from 'vue';
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
import App from './App.vue';Vue.use(ElementUI);new Vue({el: '#app',render: h => h(App)
});

• 访问官网复制组件代码，调整（比如按钮）

views/element/ElementView.vue 中

<template><div><el-row><el-button>默认按钮</el-button><el-button type="primary">主要按钮</el-button><el-button type="success">成功按钮</el-button><el-button type="info">信息按钮</el-button><el-button type="warning">警告按钮</el-button><el-button type="danger">危险按钮</el-button></el-row></div>
</template>
<script>
export default {name: "ElementView"
}
</script>
<style scoped></style>

App.vue 中导入上述组件

<template><div id="app"><ElementView></ElementView></div>
</template><style>
</style>
<script setup>
import ElementView from "@/views/element/ElementView.vue";
</script>

常见组件

表格

每一个组件对应的属性，在组件底部都有说明。

<template><el-table:data="tableData"style="width: 100%"><el-table-columnprop="date"label="日期"width="180"></el-table-column><el-table-columnprop="name"label="姓名"width="180"></el-table-column><el-table-columnprop="address"label="地址"></el-table-column></el-table></template><script>export default {data() {return {tableData: [{date: '2016-05-02',name: '王小虎',address: '上海市普陀区金沙江路 1518 弄'}, {date: '2016-05-04',name: '王小虎',address: '上海市普陀区金沙江路 1517 弄'}, {date: '2016-05-01',name: '王小虎',address: '上海市普陀区金沙江路 1519 弄'}, {date: '2016-05-03',name: '王小虎',address: '上海市普陀区金沙江路 1516 弄'}]}}}</script>

分页

<el-paginationbackgroundlayout="sizes, prev, pager, next, jumper, total"@size-change="handleSizeChange"@current-change="handleCurrentChange":total="1000">
</el-pagination>
<script>
export default {methods: {handleSizeChange: function (val) {alert("每页记录数变化" + val)},handleCurrentChange: function (val) {alert("页码发生变化" + val)}}
}</script>

layout 与下面组件的对应关系


size-change 和 current-change 事件来处理页码大小和当前页变动时候触发的事件。
