JavaWeb_Web前端_Element组件库

快速入门

安装ElementUI组件库

在当前工程的目录下, 打开命令行执行如下指令:
npm install [email protected]

引入ElementUI组件库

在main.js中添加如下代码:

import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';

Vue.use(ElementUI);

添加组件并导入到根组件

添加组件

在views目录下创建element目录, 并在element目录下创建ElementView.vue, 代码如下所示:

<template>
  <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>
</template>

<script>
export default {};
</script>

<style>
</style>

导入到根组件

在App.vue的template的div中输入如下代码:

<!-- 注意先打尖括号 -->
<element-view></element-view>

自动生成代码如下:

// 模板部分, 生成HTML代码
<template>
  <div id="app">
    ...

    <!-- 注意先打尖括号 -->
    <element-view></element-view>
  </div>
</template>

// 控制模板的数据来源和行为
<script>
import ElementView from './views/element/ElementView.vue';
export default {
  components: { ElementView },
  data() {
    ...
  },
};
</script>

// css样式部分
<style>
</style>
