1.安裝vuecli腳手架

2.終端輸入

cnpm i element-ui -S

安裝element-ui

3.按需引入select組件

在main.js中寫入如下代碼

/* 導入第三方庫開始 */import 'element-ui/lib/theme-chalk/index.css';// 按需加載Select組件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);// 或寫為Vue.use(Button)/* 導入第三方庫結束 */

HelloWorld.vue代碼

<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">確 定</el-button>   </span>  </el-dialog>   <el-select v-model="value" multiple placeholder="請選擇" @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: '選項1',     label: '黃金糕'    }, {     value: '選項2',     label: '雙皮奶'    }, {     value: '選項3',     label: '蚵仔煎'    }, {     value: '選項4',     label: '龍須面'    }, {     value: '選項5',     label: '北京烤鴨'    }],    value: '',    dialogVisible: false,    selVal : ''   }  },  methods: {   currentSel(selVal){    this.selVal = selVal;    this.dialogVisible = true;   }  } }</script>
