1.安装vuecli脚手架

2.终端输入

cnpm i element-ui -S

安装element-ui

3.按需引入select组件

在main.js中写入如下代码

/* 导入第三方库开始 */import 'element-ui/lib/theme-chalk/index.css';// 按需加载Select组件import {Select,Option,Dialog,Button} from 'element-ui'Vue.use(Select)Vue.use(Option)Vue.use(Dialog)Vue.use(Button)// Vue.component(Select.name,Select);// 或写为Vue.use(Button)/* 导入第三方库结束 */

HelloWorld.vue代码

<template><div>  <el-dialog   title="提示"   :visible.sync="dialogVisible"   width="30%">   <span>{{selVal}}</span>   <span slot="footer" class="dialog-footer">    <el-button @click="dialogVisible = false">取 消</el-button>    <el-button type="primary" @click="dialogVisible = false">确 定</el-button>   </span>  </el-dialog>   <el-select v-model="value" multiple placeholder="请选择" @change="currentSel">    <el-option     v-for="item in options"     :key="item.value"     :label="item.label"     :value="item.label">    </el-option>   </el-select></div></template><script> export default {  data() {   return {    options: [{     value: '选项1',     label: '黄金糕'    }, {     value: '选项2',     label: '双皮奶'    }, {     value: '选项3',     label: '蚵仔煎'    }, {     value: '选项4',     label: '龙须面'    }, {     value: '选项5',     label: '北京烤鸭'    }],    value: '',    dialogVisible: false,    selVal : ''   }  },  methods: {   currentSel(selVal){    this.selVal = selVal;    this.dialogVisible = true;   }  } }</script>
